BS EN 1736 is a European Standard that describes the requirements, design, and installation of flexible pipe elements (e. g. metallic flexible pipe, metallic flexible tube, vibration isolator, expansion joint) and non-metallic tube used in the refrigerant circuits of refrigerating systems and heat pumps.
BS EN 1736 also describes the requirements to qualify the tightness of non-metallic tubes (e.g. plastic) used in evaporating and/or condensing sides of refrigerating systems and heat pumps.
BS EN 1736 does not apply to flexible pipes that are only occasionally stressed beyond the elastic limit, e. g. during repair work, or to joints that are free to rotate or hinge.
BS EN 1736 on refrigerating systems and heat pumps useful for:
The use of flexible pipe elements is required where impermissible stresses are to be eliminated from refrigerating circuits and pipe expansion or relative movements of components are to be absorbed.
BS EN 1736 provides you with best industry requirements of materials, pressure and pulsation requirements, allowable permeabilities for non-metallic flexible tubes, along with test methods that help demonstrate whether the flexible pipe elements are safe, reliable and effective at the point of use.
If you are a manufacturer of flexible pipe elements used in refrigerating systems and heat pumps, BS EN 1736 can not only minimize the risk of product failures but also ensure that its contribution to the environmental impact due to the permeation of a refrigerant through flexible tubes, remains as low as reasonably practicable.
