What certainly draws attention is the solid workmanship . Walraven BIS clamps are characterized by the ability to carry large and heavy loads. All this is due to the CO 2 welded connection nut, solid closure, and high-quality steel. It should not be forgotten that each clamp is tested for its functional properties in the event of a fire .

The Walraven clamp is suitable for both indoor and outdoor use. It is corrosion resistant (suitable for corrosive environments: C1-c4 according to ISO 12944-2). This is proven by the fact that all applied surface finishes have successfully passed the 1000-hour salt spray test .
Moreover, these products have been awarded the RAL certificate . In accordance with the requirements of RAL-GZ 655, the test results of products marked with the "RAL" symbol are certified and monitored by independent research institutes. The maximum recommended load (Fa, z) is calculated using statistical methods in relation to the breaking force, the element deformation up to 1.5 mm or 2% of the nominal clamp size is taken into account for the calculation.
BIS HD 1501 pipe clamp with EPDM lining
The discussed BIS HD 1501 clamp is made of 1.0332 steel (according to EN 10111) and EDPM sound-insulating lining (according to DIN4109). The surface is covered with an element of the BIS UltraProtect 1000 system. Thanks to this surface, the BIS HD 1501 clamp can also be used outside buildings.
