What is BS EN 15698‑2 - Twin-pipe assembly about?
BS EN 15698 is a series of European standards on district heating pipes that discusses the best procedures and specifications required for building safe thermally insulated bonded twin-pipe assemblies. BS EN 15698‑2 is the second part of a series of documents on district heating pipes. BS EN 15698‑2 specifies requirements and test methods for fittings of factory-made thermally insulated bonded twin-pipe assemblies for hot water networks by EN 13941‑1, comprising two steel services fittings and/or valves, polyurethane foam thermal insulation, and one casing of polyethylene.
The pipe assembly can also include the following additional elements: measuring wires, spacers, and diffusion barriers.
NOTE 1: BS EN 15698‑2 covers the following assemblies:
- Fittings: bends, T-pieces, and reducers
- Valve construction
NOTE 2: BS EN 15698‑2 applies to fitting and valve assemblies with a minimum design pressure of 1,6 MPa (overpressure).
Who is BS EN 15698‑2 - Twin-pipe assembly for?
BS EN 15698‑2 on district heating pipes is relevant to:
- Manufacturer of thermally insulated bonded twin-pipe assemblies
Why should you use BS EN 15698‑2 - Twin-pipe assembly?
Thermally insulating bonding and coating compounds help in lowering heat transfer and improving product reliability in many applications ranging from electronics devices to ovens to processing equipment to pipes to appliances.
BS EN 15698‑2 navigates you through the welding of steel pipes and elements, welding of fixing bars placing of the fixing bars, polyurethane (PUR) rigid foam thermal insulation, fitting and valve assemblies, requirements for effective operation and maintenance, surveillance system.
As a user of BS EN 15698‑2, you would get appropriate guidance regarding the requirements and test methods for manufacturing thermally insulated bonded twin-pipe assemblies for directly buried hot water networks. BS EN 15698‑2 supplies tried and tested methods that will help users achieve high-quality installations. BS EN 15698‑2 takes into account safety and protection while also prolonging the service life of the twin-pipe assembly.
What’s changed since the last update?
BS EN 15698‑2:2019 supersedes BS EN 15698‑2:2015, which is withdrawn.
In comparison with the previous edition, the main changes in EN 15698‑2 are:
- Editorial changes to the new structure of standards prepared by the Technical Committee CEN/TC 107
