APP’s lined hold down clamps are constructed to dampen vibration in piping systems and designed for heavy-load scenarios in high-stress environments, such as compressors and reciprocating equipment. These clamps prolong the life of your piping system.
We offer numerous hold down clamp liners, including APP’s proprietary dual-layer VibraTek liner, Fabreeka®, Urethane, Neoprene, and sodium-etched Teflon, to meet or exceed your project’s specifications.
Our most popular liner, the dual-layer VibraTek liner, incorporates specialized fiber-backed Teflon to add a low coefficient of friction between the pipe and the clamp to the liner’s vibration-dampening qualities.
The VibraTek liner has been used in high-stress projects across the world. It minimizes stress to piping and structural components and, because of mechanical bonds created by fibers infused during manufacturing, it won’t delaminate. This liner reduces energy consumption, noise, and costs.
APP-VibraTek and HB-Teflon
If VibraTek is not desired, other options include Fabreeka®, Urethane, Neoprene, and sodium-etched Teflon.
-60°F to +450°F
Will fabricate to specific dimensions.
Yes — we can line hold down clamps with your choice of lining materials: proprietary dual-layer VibraTek liner, Fabreeka®, Urethane, Neoprene, or sodium-etched Teflon.
Yes — we can fabricate clamps to your exact dimensions. We can also make them with or without base plates as required.
Hot-dip galvanization is the most common finish for hold down clamps, but APP is able to paint per your specifications as well.
With the VibraTek liner, the maximum compressive strength is 20,000 lbs with a temperature range of -60°F to +450°F and a tensile strength (ASTM D412) of 725 psi.
No — HB Teflon will not delaminate, thanks to the strong mechanical bond created by the fibers infused during manufacturing.
hold down straps are designed to protect the coating of uninsulated carbon steel pipes while keeping the pipe securely in place.View Product
ProTek u-bolts restrain the pipe while shielding it from metal to metal contact and rough abrasion from pipe movement.View Product
Standard u-bolts are are bent to form a U that fits around a pipe or tube. It is threaded on both ends to allow attachment to a beam or structure.View Product
