Standard Practice for The Sectional Repair of Damaged Pipe By Means of An Inverted Cured-In-Place Liner

Standard Practice for The Sectional Repair of Damaged Pipe By Means of An Inverted Cured-In-Place Liner

SIGNIFICANCE AND USE
This practice is for use by designers and specifiers, regulatory agencies, owners, and inspection organizations who are involved in the rehabilitation of pipes through the use of a resin-impregnated tube installed within a damaged existing pipe. As for any practice, modifications may be required for specific job conditions.
SCOPE
1.1 This practice covers requirements and test methods for the sectional cured-in-place lining (SCIPL) repair of a pipe line (4 in, through 60 in. ) by the installation of a continuous resin-impregnated-textile tube into an existing pipe by means of air or water inversion and inflation. The tube is pressed against the host pipe by air or water pressure and held in place until the thermo set resins have cured. When cured, the sectional liner shall extend over a predetermined length of the host pipe as a continuous, one piece, tight fitting, corrosion resistant and verifiable non-leaking cured-in-place pipe.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that provided for information only and are not considered standard.
1.3 There is no similar or equivalent ISO Standard.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Particular attention is drawn to those safety regulations and requirements involving entering into and working in confined spaces.

Standard Test Method for Joint Restraint Products for Use with PVC Pipe

ABSTRACT
This test method describes a procedure for qualifying the performance of joint restraint products for use on PVC pressure pipe systems by evaluating the effect of the joint restraint product on the performance characteristics of PVC pipe during cyclic pressure tests and static pressure tests. This test method is useful for establishing any effects that a joint restraint product has on the performance of PVC pressure pipe. This test method is designed so that success in all three parts of the test provides reasonable assurance that a joint restraint product may be used on PVC pipe at the full pressure rating and capacity of the pipe. Pipe specimen length, minimum burst pressure test, sustained pressure test, and cyclic surge pressure test shall be performed to conform with the specified requirements.
SIGNIFICANCE AND USE
4.1 This test method is useful for establishing any effects that a joint restraint product has on the performance of PVC pressure pipe. This test method is designed so that success in all three parts of the test provides reasonable assurance that a joint restraint product may be used on PVC pipe at the full pressure rating and capacity of the pipe.  
4.2 Restrained joint test specimens shall be subjected to internal pressures that are equal to the minimum burst pressure requirements for the pipe alone. The minimum burst pressure requirements for some common dimension ratios are shown in Table 1. The minimum burst pressures for other dimension ratios of pipe produced from 12454 PVC Compound (that is, pipe conforming to Specification D1785) may be determined based on a hoop stress of 6400 psi (44.13 MPa).  (A) The pressures listed approximate a hoop stress of 6400 psi (44.13 MPa). Some minor adjustments have been made to keep the test pressures uniform in order to simplify testing.  
4.3 Testing of restrained joint test specimens for 1000 h at the sustained pressure requirements indicates any tendency of the restraint to fail in the long term. The minimum sustained pressure requirements for some common dimension ratios are shown in Table 2. The minimum sustained pressure for other dimension ratios of pipe produced from 12454 PVC Compound (for example, pipe conforming to Specification D1785) may be determined based on a hoop stress of 4200 psi (28.96 MPa).  (A) The pressures listed approximate a hoop stress of 4200 psi (28.96 MPa). Some minor adjustments have been made to keep the test pressures uniform in order to simplify testing.  
4.4 A cyclic surge pressure test of restrained joint test specimens determines the effect of the joint restraint product on the cyclic fatigue life of PVC pipe. This test method provides a means for quickly identifying any reduction in performance that might result from the combination of the joint restraint product and the pipe. The...
SCOPE
1.1 This test method describes a procedure for qualifying the performance of joint restraint products for use on PVC pressure pipe systems by evaluating the effect of the joint restraint product on the performance characteristics of PVC pipe during cyclic pressure tests and static pressure tests. The PVC pipe property values referenced in this test method are for the 12454 compound as described in Specification D1784 and a 4,000 HDB shall be obtained by categorizing the LTHS in accordance with Table 1 in Test Method D2837. That includes, but is not limited to, pipe produced in accordance with the following standards: Specifications D1785 and D2241, and AWWA C900.  
1.2 This test method determines the short-term performance of a joint restraint product on PVC pipe, which involves the testing of restrained joint test sections to the minimum burst pressure requirements of the pipe to determine quick burst performance.  
1.3 This test method determines the long-term effect of a joint restraint product on PVC pipe, which involves the testing of restrained joint test sections to the sustained pressure requirements of...

Standard Test Methods for Holiday Detection of Coatings used to Protect Pipelines

SIGNIFICANCE AND USE
5.1 Method A—Low voltage holiday detection is used to locate holidays and pinholes in thin-film coatings (up to 0.508 mm (20 mils) using a sponge wetted with tap water (and a wetting agent for coatings thicker than 10 mils). The water carries the current from the electrode through the holiday to the conductive substrate. The detector is grounded to the coated substrate. When the detector senses this flow of current it alarms.  
5.2 Method B—High voltage holiday detection is used to locate holidays and pinholes in thick-film coatings (greater than 20 mils), but can be used on coatings as low as 10 mils thick. A test voltage is selected and set. A charged Electrode is placed in contact with the coating, and the Detector is grounded to the coated substrate. When Electrical Breakdown occurs, electric current flows between the Detector’s electrode and the conductive substrate and emits an audible alarm.  
5.3 This standard does not apply to holiday detection of tape wraps used to protect pipe or coatings containing conductive raw materials such as conductive pigments and extenders.  
5.4 The thickness of a coating applied to ductile iron pipe, fittings, or other iron castings may vary substantially due to the inherent roughness of the substrate. For these applications, consult the coating manufacturer for their recommended test voltage setting when using Method B. The coating manufacturer’s recommended test voltage setting may be subject to approval by the owner.
Note 1: Use of voltage settings lower than those listed in this standard may increase the likelihood of non-detection.
SCOPE
1.1 These test methods cover the apparatus and procedures for detecting pinholes and holidays in coatings used to protect pipelines.  
1.2 Method A is designed to detect pinholes and holidays in thin-film coatings from 0.025 mm to 0.254 mm (1 mils to 10 mils) in thickness using ordinary tap water and an applied voltage of less than 100 V d-c. It is effective on films up to 0.508 mm (20 mils) thickness if a wetting agent is used with the water.  
1.3 Method B is designed to detect pinholes and holidays in thick-film coatings >0.508 mm (20 mils) This method can be used on any thickness of pipeline coating and utilizes applied voltages between 3.4 and 35 kV d-c.  
1.4 The values stated in SI units to three significant decimals are to be regarded as the standard. The values given in parentheses are for information only.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Pneumatic Leak Testing of Tubing

SIGNIFICANCE AND USE
5.1 When permitted by a specification or the order, this test method may be used for detecting leaks in tubing in lieu of the air underwater pressure test.
SCOPE
1.1 This test method provides procedures for the leak testing of tubing using pneumatic pressure. This test method involves measuring the change in pressure inside the tubing over time. There are three procedures that may be used, all of which are intended to be equivalent. It is a qualitative not a quantitative test method. Any of the three procedures are intended to be capable of leak detection and, as such, are intended to be equivalent for that purpose.  
1.2 The procedures will produce consistent results upon which acceptance standards can be based. This test may be performed in accordance with the Pressure Differential (Procedure A), the Pressure Decay (Procedure B), or the Vacuum Decay (Procedure C) method.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.3.1 Within the text, the SI units are shown in brackets.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Determination of Elemental Sulfur in Natural Gas

SIGNIFICANCE AND USE
5.1 Elemental sulfur impacts the quality of pipeline natural gas and deposits on pipeline flanges, fittings and valves, thereby impacting their performance. Natural gas suppliers and distributers require a standardized test method for measuring elemental sulfur. Some government regulators are also interested in measuring elemental sulfur since it would provide a means for assessing the contribution of elemental sulfur in pipelines to the SOx emission inventory from burning of gaseous fuels. Use of this method in concert with sulfur gas laboratory test methods such as Test Methods D4084, D4468, D5504, and D6228 or on-line methods such as D7165 or D7166 can provide users with a comprehensive sulfur compound profile for natural gas or other gaseous fuels. Other applications may include elemental sulfur in particulate deposits such as diesel exhausts.
SCOPE
1.1 This test method is primarily for the determination of elemental sulfur in natural gas pipelines, but it may be applied to other gaseous fuel pipelines and applications provided the user has validated its suitability for use. The detection range for elemental sulfur, reported as sulfur, is 0.0018 mg/L to 30 mg/L. The results may also be reported in units of mg/kg or ppm.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM E2929-18(2022)(Practice)
Standard Practice for Guided Wave Testing of Above Ground Steel Piping with Magnetostrictive Transduction

SIGNIFICANCE AND USE
5.1 The purpose of this practice is to outline a procedure for using GWT to locate areas in metal pipes in which wall loss has occurred due to corrosion or erosion.  
5.2 GWT does not provide a direct measurement of wall thickness, but is sensitive to a combination of the CSC (or reflection coefficient) and circumferential extent and axial extent of any metal loss. Based on this information, a classification of the severity can be assigned.  
5.3 The GWT method provides a screening tool to quickly identify any discontinuity along the pipe. Where a possible defect is found, a follow-up inspection of suspected areas with ultrasonic testing or other NDT methods is normally required to obtain detailed thickness information, nature, and extent of damage.  
5.4 GWT also provides some information on the axial length of a discontinuity, provided that the axial length is longer than roughly a quarter of the wavelength.  
5.5 The identification and severity assessment of any possible defects is qualitative only. An interpretation process to differentiate between relevant and non-relevant signals is necessary.  
5.6 This practice only covers the application specified in the scope. The GWT method has the capability and can be used for applications where the pipe is insulated, buried, in road crossings, and where access is limited.  
5.7 GWT shall be performed by qualified and certified personnel, as specified in the contract or purchase order. Qualifications shall include training specific to the use of the equipment employed, interpretation of the test results, and guided wave technology.  
5.8 A documented program which includes training, examination, and experience for the GWT personnel certification shall be maintained by the supplying party.
SCOPE
1.1 This practice provides a guide for the use of waves generated using magnetostrictive transduction for guided wave testing (GWT) welded tubulars. Magnetostrictive materials transduce or convert time varying magnetic fields into mechanical energy. As a magnetostrictive material is magnetized, it strains. Conversely, if an external force produces a strain in a magnetostrictive material, the material’s magnetic state will change. This bi-directional coupling between the magnetic and mechanical states of a magnetostrictive material provides a transduction capability that can be used for both actuation and sensing devices.  
1.2 GWT utilizes ultrasonic guided waves in the 10 to approximately 250 kHz range, sent in the axial direction of the pipe, to non-destructively test pipes for discontinuities or other features by detecting changes in the cross-section or stiffness of the pipe, or both.  
1.3 GWT is a screening tool. The method does not provide a direct measurement of wall thickness or the exact dimensions of discontinuities. However, an estimate of the severity of the discontinuity can be obtained.  
1.4 This practice is intended for use with tubular carbon steel products having nominal pipe size (NPS) 2 to 48 corresponding to 60.3 to 1219.2 mm (2.375 to 48 in.) outer diameter, and wall thickness between 3.81 and 25.4 mm (0.15 and 1 in.).  
1.5 This practice only applies to GWT of basic pipe configuration. This includes pipes that are straight, constructed of a single pipe size and schedules, fully accessible at the test location, jointed by girth welds, supported by simple contact supports and free of internal, or external coatings, or both; the pipe may be insulated or painted.  
1.6 This practice provides a general practice for performing the examination. The interpretation of the guided wave data obtained is complex and training is required to properly perform data interpretation.  
1.7 This practice does not establish an acceptance criterion. Specific acceptance criteria shall be specified in the contractual agreement by the cognizant engineer.  
1.8 Units—The values stated in SI units are to be regarded as standard. The values given...

(10.2 cm through 152 cm)) by the installation of a continuous resin-impregnated-textile tube into an existing host pipe by means of air or water inversion and inflation. The tube is pressed against the host pipe by air or water pressure and held in place until the thermoset resins have cured. When cured, the sectional liner shall extend over a predetermined length of the host pipe as a continuous, one piece, tight fitting, corrosion resistant, and verifiable non-leaking cured-in-place pipe.
