BS EN 253:2019

What is BS EN 253 - District heating pipes about?  

BS EN 253 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 pipe assemblies. BS EN 253 specifies requirements and test methods for straight lengths of factory-made thermally insulated bonded single pipe assemblies for hot water networks by EN 13941-1, comprising a steel service pipe, polyurethane foam thermal insulation, and a casing of polyethylene. 

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

Who is BS EN 253- District heating pipes for?  

BS EN 253 on district heating pipes is relevant to: 

• Manufacturer of thermally insulated bonded single pipe assemblies 

Why should you use BS EN 253- 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 253 navigates you through the surface condition, material composition, melt mass-flow rate, thermal stability, casing properties,  polyurethane (PUR) foam thermal insulation, pipe assembly, and test methods 

BS EN 253 exemplifies the required steel service pipe dimensions, casing dimensions, and thermal insulation series that help you achieve precision in terms of product functionality. 

As a user of BS EN 253, you can be ensured of all the requirements and test methods of thermally insulated bonded single pipe assemblies for hot water networks. BS EN 253 supplies tried and tested methods that will help users achieve precision in terms of products specification. BS EN 253 takes into account safety and protection while also prolonging the service life of the polyurethane (PUR) foam thermally insulated pipe assembly. 

What’s changed since the last update?  

BS EN 253:2019 supersedes BS EN 253:2009+A2:2015, which is withdrawn. 

In comparison with the previous edition, the main changes in this new edition of EN 253 are: 

• Editorial changes to the new structure of standards prepared by the Technical Committee CEN/TC 107
• Specification of steel grade moved into EN 13941-1 
• Added thermal insulation series, and linear water tightness: requirements and test method 
• Revised description of expected thermal life and long term temperature resistance in balance with EN 13941-1, revised description on shear strength: requirements and test method 
• Removed Tangential shear strength and long-term creep resistance and modulus
• Revised Annex A, “Relation between actual continuous operating condition and accelerated aging test conditions” 
• Removed Annex C, “Calculated Continuous Operating Temperature (CCOT)”
