What is BS EN 156981- 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 156981 is the first part of a series of documents on district heating pipes. BS EN 156981 specifies requirements and test methods for straight lengths of factory-made thermally insulated bonded twin-pipe assemblies for directly buried hot water networks by EN 13941-1, comprising two steel service pipes, rigid 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. 

Who is BS EN 156981- Twin-pipe assembly for?  

BS EN 156981 on thermally insulated bonded twin-pipe assemblies is relevant to: 

  • Manufacturer of thermally insulated bonded twin-pipe assemblies  

Why should you use BS EN 156981- 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 156981 navigates you through the steel service pipe, casing, polyurethane (PUR) rigid foam thermal insulation, pipe assembly, twisting of steel service pipes, axial shear strength, expected thermal life, and long term temperature resistance, thermal conductivity in unaged condition and test methods. 

BS EN 156981 exemplifies the required casing diameters that help you achieve precision in terms of product functionality. 

As a user of BS EN 156981, you would get appropriate guidance regarding the requirements and test methods of thermally insulated bonded twin-pipe assemblies for directly buried hot water networks. BS EN 156981 supplies tried and tested methods that will help users achieve high-quality installations. BS EN 156981 takes into account safety and protection while also prolonging the service life of the twin-pipe assembly.
