BS EN 448:2019

What is BS EN 448 - District heating pipes about?  

BS EN 448 is a European standard on district heating pipes bearings that discusses the best procedures and specifications required for manufacturing high-quality thermally insulated bonded single fitting assemblies. BS EN 448 specifies requirements and test methods for factory-made thermally insulated bonded fitting assemblies for hot water networks by EN 13941‑1, comprising a steel service fitting, rigid polyurethane foam thermal insulation, and a casing of polyethylene. 

The fitting assembly could also include the following additional elements: measuring wires, spacers, and diffusion barriers. 

NOTE 1: BS EN 448 covers the following fitting assemblies: bend, tee, reducer, single-use compensator, and anchor. 

NOTE 2: BS EN 448 applies to fitting assemblies with a minimum design pressure of 1,6 MPa (overpressure). 

Who is BS EN 448 - District heating pipes for?  

BS EN 448 on district heating pipes is relevant to: 

• Manufacturer of thermally insulated fitting assemblies  

Why should you use BS EN 448- District heating pipes? 

Thermal insulation aims to prevent heat loss in heating systems and warm water supplies.  

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 448 navigates you through the steel parts, casing, polyurethane (PUR) foam thermal insulation, fitting assemblies, surveillance system, and test methods. 

BS EN 448 exemplifies the required non-destructive examination that helps you achieve precision in terms of product functionality. 

As a user of BS EN 448, you can be ensured of all the requirements and test methods of thermally insulated fitting assemblies for hot water networks. BS EN 448 supplies tried and tested methods that will help users achieve precision in terms of products specification. BS EN 448 takes into account safety and protection while also prolonging the service life of the polyurethane (PUR) foam thermally insulated fitting assemblies.
