General Information
Frequently Asked Questions
ICS 23.040.07 is a classification code in the International Classification for Standards (ICS) system. It covers "Pipeline and its parts for district heat". The ICS is a hierarchical classification system used to organize international, regional, and national standards, facilitating the search and identification of standards across different fields.
There are 121 standards classified under ICS 23.040.07 (Pipeline and its parts for district heat). These standards are published by international and regional standardization bodies including ISO, IEC, CEN, CENELEC, and ETSI.
The International Classification for Standards (ICS) is a hierarchical classification system maintained by ISO to organize standards and related documents. It uses a three-level structure with field (2 digits), group (3 digits), and sub-group (2 digits) codes. The ICS helps users find standards by subject area and enables statistical analysis of standards development activities.

The principles of the standard may be applied to thermal insulated pipe systems with pressures higher than 2,5 MPa, provided that special attention is paid to the effects of pressure.
Adjacent pipes, not buried, but belonging to the network (e. g. pipes in ducts, valve chambers, road crossings above ground etc.) may be designed and installed according to this standard.
This standard presupposes the use of treated water, which by softening, demineralisation, de-aeration, adding of chemicals, or otherwise has been treated to effectively prevent internal corrosion and deposits in the pipes.
This standard is not applicable for such units as:
a) pumps;
b) heat exchangers;

SCOPE
1.1 This specification covers direct buried underground pre-insulated, hot water piping systems with an upper temperature limit of 250 °F (121 °C) used to convey pressurized fluids for district heating. In the pre-insulated pipe industry and in this standard, this temperature range is called “low temperature hot water”.
1.2 This specification shall not be used for low-pressure steam systems, steam trap discharge or pressurized condensate systems, since there is a high risk of exceeding the upper temperature limits. Pumped condensate return lines that are vented to atmosphere are considered to be low temperature hot water and are acceptable for this application.
1.3 This specification covers only piping systems insulated and jacketed with bonded polyurethane (PUR) rigid foam. A piping system consists of both straight sections of pre-insulated piping as well as pre-insulated fittings and field closures of the insulation system, and all materials required to ensure a water tight insulation system which will preclude water from entering the insulation from the surrounding soil. This specification does not encompass insulating or jacketing materials, or insulation methods, which do not produce factory, pre-fabricated, insulated and jacketed units for assembly at the field site.
1.4 The insulated piping systems covered by this specification do not possess an air gap between the carrier pipe and the insulation nor between the insulation and jacket. For straight pipe sections of the piping systems covered by this specification, these three components are bonded together.
1.5 The carrier piping that is part of the insulated piping system covered by this specification shall be designed, fabricated, and tested to the requirements of ANSI/ASME B31.1 (Power Piping).
1.6 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 are provided for information only and are not considered to be the standard.
1.7 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.
1.8 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 document specifies the methods of examining the knowledge and skill set of the fitter required to carry out on-site joint casing connections on thermally insulated single and twin pipe systems for directly buried hot and cold water networks according to .The application of these specified methods specifications ensures that the examination is carried out according to a standardised examining procedure.This document covers the following processes:
- preparatory works for joint casing assembly;
- assembling and testing the elements for surveillance systems;
For special surveillance systems it can be important to have additional training.preparing work for joint casing system installation;
- assembling sealable joint casing system;
- verifying joint tightness (leakage testing);
- thermally insulating the joint casing ( PUR foaming or half-shells);
- sealing fill & vent openings (weldable or sealable plugs);
- assessing overall installation quality of the completed joint connection (non-destructive).

This European Standard specifies requirements for design, calculation and installation of factory made thermal insulated bonded single and twin pipe systems for directly buried hot water networks for continuous operation with treated hot water at various temperatures up to 120 ºC and occasionally with peak temperatures up to 140 ºC and maximum internal pressure 2,5 MPa. Flexible pipe systems according to EN 15632 are not under the scope of this standard.
The standard EN 13941, Design and installation of thermal insulated bonded single and twin pipe systems for directly buried hot water networks consists of two parts:
a) prEN 13941-1: Design;
b) prEN 13941-2: Installation.
The requirements and stipulations in this part: EN 13941-1, form an unbreakable unity with those of prEN 13941-2. This part shall therefore exclusively be used in combination with prEN 13941-2.
The principles of the standard may be applied to thermal insulated pipe systems with pressures higher than 2,5 MPa, provided that special attention is paid to the effects of pressure.
Adjacent pipes, not buried, but belonging to the network (e. g. pipes in ducts, valve chambers, road crossings above ground etc.) may be designed and installed according to this standard.
This standard presupposes the use of treated water, which by softening, demineralisation, de-aeration, adding of chemicals, or otherwise has been treated to effectively prevent internal corrosion and deposits in the pipes.
NOTE For further information on water qualities to be used in district heating pipe systems see also [1].
This standard is not applicable for such units as:
a) pumps;
b) heat exchangers;
c) boilers, tanks;
d) systems behind domestic substations.
