SCOPE
1.1 This specification covers billets made from stress-rated high-density polyethylene (HDPE) materials.
1.2 The billets are manufactured by application of molten extruded material onto a rotating mandrel to form a monolithic mass. Removal of the mandrel provides a billet in the approximate shape of a thick-walled cylindrical shell. Machining prior to dimensioning is acceptable.
Note 1: Although it is impossible to address all manufacturing details related to the fabrication of billets in this specification, successful heat fusion bonding of HDPE is obtained through controlled application of sufficient heat to cause melting in combination with applied force over a period of time.
1.3 The billets are intended for fabrication into pipe fittings such as flange adapters and reducers.
1.4 Requirements for and use of the fabricated pipe fittings shall be in accordance with an applicable product specification. This specification for billets does not include requirements for items fabricated from the billets.
1.5 This specification includes thermoplastic pipe material designation codes for selection of appropriate stress-rated material, together with performance requirements for billets and test methods for determining conformance with the requirements.
1.6 Minimum quality control measures are prescribed for manufacturers. See Annex A1 for quality control for billets conforming to this specification.
1.7 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.8 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.
1.9 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.

Overview
ASTM F3034-21: Standard Specification for Billets made by Winding Molten Extruded Stress-Rated High Density Polyethylene (HDPE) sets forth the requirements for billets manufactured from stress-rated HDPE materials. These billets are produced by winding molten, extruded HDPE onto a rotating mandrel, resulting in a monolithic cylindrical shell. Primarily intended for fabrication into pipe fittings such as flange adapters and reducers, the standard specifies the necessary material properties, performance criteria, and quality assurance practices to ensure the integrity and durability of billets that serve as the starting point for further processing.
This specification provides material designation codes, test methods for performance validation, limitations on dimensions and tolerances (when sold as billets), and prescribes essential in-plant quality control measures.
Key Topics
Material Requirements:
- Only stress-rated HDPE compounds (e.g., PE3608, PE4608, PE4710 with cell classification 333344C per ASTM D3350) are permitted.
- Virgin or reworked PE compounds which meet all criteria are allowed.
- For potable water applications, certification to NSF/ANSI Standard No. 61 or the health effects portion of Standard No. 14 is required.
Manufacturing Process:
- Billets are formed by layering molten HDPE onto a rotating mandrel.
- Final billets resemble thick-walled cylindrical shells, which can be further machined to required dimensions.
Performance Requirements:
- Criteria include acceptable carbon black content (2.0-3.0 wt%), minimum elongation at break in tensile tests (radial and circumferential), and sufficient thermal stability.
- Workmanship standards require billets to be free from visible defects impacting wall integrity.
Dimensional Tolerances:
- Dimensional requirements apply only when billets are transferred prior to fabrication into fittings. Dimensions are defined per standardized tables for various mandrel sizes.
Testing and Certification:
- Stringent tests for thermal stability, carbon black content, and tensile properties are mandated.
- Billets must be sampled and conditioned as per referenced ASTM test methods (e.g., D638, D1603, D2122).
- Annual qualifications test billets of smallest and largest outside diameters for continued compliance.
Marking & Documentation:
- Markings must include the ASTM designation, size, material code/cell classification, manufacturer ID, and production details.
- Certification of compliance is required when stated in the purchase order.
Applications
ASTM F3034-21 is critical in industries that rely on high-quality, stress-rated HDPE billets for further fabrication into pipe fittings. Key application areas include:
Municipal and Industrial Pipe Systems:
- Billets fabricated into flange adapters, reducers, and other essential pipe fittings used in water supply, wastewater, and chemical transport systems.
Potable Water Systems:
- When HDPE billets are intended for drinking water applications, compliance with NSF/ANSI health standards ensures suitability and regulatory acceptance.
Infrastructure Projects:
- Essential for manufacturers creating large-diameter HDPE piping systems for sewers, stormwater, and drainage.
Custom HDPE Fittings Manufacturing:
- Used as blanks for CNC machining or additional fabrication steps to produce custom pipe connection solutions.
By standardizing billet quality, ASTM F3034-21 supports consistency across the HDPE piping supply chain, enhances product reliability, and reduces risk of failure in the field.
Related Standards
For optimal results and conformance with ASTM F3034-21, reference and compatibility with the following standards should be ensured:

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: F3034 − 15 (Reapproved 2020) F3034 − 21 An American National Standard
Standard Specification for
Billets made by Winding Molten Extruded Stress-Rated High
Density Polyethylene (HDPE)
This standard is issued under the fixed designation F3034; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope*
1.1 This specification covers billets made from stress-rated high-density polyethylene (HDPE) materials.
1.2 The billets are manufactured by application of molten extruded material onto a rotating mandrel to form a monolithic mass.
Removal of the mandrel provides a billet in the approximate shape of a thick-walled cylindrical shell. Machining prior to
dimensioning is acceptable.
NOTE 1—Although it is impossible to address all manufacturing details related to the fabrication of billets in this specification, successful heat fusion
bonding of HDPE is obtained through controlled application of sufficient heat to cause melting in combination with applied force over a period of time.
1.3 The billets are intended for fabrication into pipe fittings such as flange adapters and reducers.
1.4 Requirements for and use of the fabricated pipe fittings shall be in accordance with an applicable product specification. This
specification for billets does not include requirements for items fabricated from the billets.
1.5 This specification includes thermoplastic pipe material designation codes for selection of appropriate stress-rated material,
together with performance requirements for billets and test methods for determining conformance with the requirements.
1.6 Minimum quality control measures are prescribed for manufacturers. See Annex A1 for quality control for billets conforming
to this specification.
1.7 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and are not considered standard.
1.8 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.
1.9 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.
This specification is under the jurisdiction of ASTM Committee F17 on Plastic Piping Systems and is the direct responsibility of Subcommittee F17.26 on Olefin Based
Pipe.

5.2.2 Length—Any length shall be allowable, provided it is agreeable to both buyer and seller. When specified, the minimum
length shall be measured following conditioning according to Practice D618, Procedure A to standard temperature without regard
to relative humidity.
5.2.3 Special Sizes—Where existing system conditions or special local requirements make other average outside diameters or
minimum wall thicknesses necessary, other average outside diameters or minimum wall thicknesses, or both, shall be acceptable
when mutually agreed upon by the customer and the manufacturer, provided the billet meets all other requirements of this
specification. For average outside diameters not shown in Table 1 or Table 2, the tolerance shall be the same percentage as that
used in Table 1 or Table 2 for the next smaller listed average outside diameter. Maximum and minimum wall thicknesses for
mandrel sizes not shown in Table 1 or Table 2 shall be determined by subtracting the mandrel size from the maximum and
minimum average outside diameter, respectively, then dividing by 2 and, finally, by rounding the third decimal place of the
resulting value to give the maximum or minimum wall thickness respectively.
5.3 Thermal Stability—The PE material shall contain sufficient antioxidant so that the minimum induction temperature for
mid-wall, outside diameter and inside diameter shall each be 428°F (220°C) when tested in accordance with both Specification
D3350 and 6.4 Thermal Stability Testing. Failure to meet this requirement shall be cause to reject the billet as unsuitable for this
standard without allowance for retesting.
