Thinking about using the Walraven BISMAT® Clamp?

Have a look at some quick FAQs to help you decide

How do I accommodate thermal expansion in pipe installations?

Pipework expands and contracts as temperatures change. The right support arrangement, with fixed and sliding points, helps maintain system integrity and prevent unnecessary stress on the pipework. Walraven BISMAT® Flash and Walraven BISMAT® 1000 have an integrated sound insulating lining according to DIN 4109.

Why use Walraven BISMAT® 5000 instead of a standard pipe clamp?

Standard pipe clamps may restrict pipe movement, which can cause stress in plastic pipe systems. Walraven BISMAT® 5000 is designed specifically for plastic pipes and features a smooth, UV-resistant EPDM lining that supports thermal expansion and contraction. Combined with removable spacer washers for fixed or sliding point installations, it helps create a safer and more durable pipe support system.

How do I install pipe clamps faster when working overhead?

When installing large numbers of pipe supports, every second counts. Walraven BISMAT® Flash features a quick-closing mechanism that lets you lock the clamp with a simple thumb push; no tool is needed. This reduces handling time and makes repetitive overhead installations easier.
