This category of clamps is designed for online sealing of leaks for various pressure-ratings and materials. Its convenient installation process, innovative sealing system, and the high degree of customization-room present in the design make the Pipe-Fit series a market leader as the solution to a variety of damage profiles. These clamps can be further seal welded or injected with sealant to achieve higher degrees of defenses against corrosion or other environmental factors.

The Pipe-Tight connection system is a mechanical fitting to join and reinforce two pipe bare ends. Used for repair, replace, and reroute operations with minimum installation time supports the resumption of the operation before much loss of revenue occurs. The Pipe-Tight can be anchored by back up clamps, extra bolting, or welding according to specific pipeline requirements.
Pipe-Tight products connect two onshore pipe ends without a flange by centralizing and gripping the ends while sealing the connection. We design both one sided flange Pipe-Tight models and enhanced models with extra sealing rows and added gripping trust screws for specific applications.
The coupling contains a seamless shell, sealing gaskets, pushing rings, circumferential trust screws, activation screws along with features like lifting lugs, welding edges and optional back up ring clamps. Material selection is as per project specific requirement; Normally A216 cast, A105 forged, A106 pipe, or A516 plate for metallic components and NBR, HNBR, Viton for elastomers. PipeTights are available from 4” to 56” for API 5L standard pipelines.
