Double Flanged Loose Sleeve Force Transfer Joint

In the demanding world of pipeline construction and maintenance, ensuring reliable connections that allow for controlled movement and easy assembly is paramount. Our DI Double Flange Power Transmission Dismantling Joint stands as a robust solution engineered for superior performance. This specialized fitting is designed to transmit thrust forces efficiently while providing a convenient breakpoint for pipeline disassembly, a feature critical for system integrity and serviceability. For projects requiring a versatile and secure connection, our standard Double Flange Dismantling Joint offers exceptional adaptability across various applications. For the highest level of structural integrity under significant pressure and axial loads, we recommend our premium Ductile Iron Double Flange Dismantling Joint with Tie Rods. This reinforced design incorporates high-strength tie rods to constrain movement and absorb pipeline thrust, making it ideal for critical installations.

The primary function of the Double Flanged Loose Sleeve Force Transfer Joint is to manage pipeline stresses effectively. It accommodates axial extension, contraction, and minor angular deflection while simultaneously transferring the pipeline's thrust force to the adjacent structure or anchor point. This prevents stress concentration on pumps, valves, and other sensitive equipment. Key to its design is the loose sleeve, which allows for the controlled telescopic movement. The double-flanged configuration facilitates straightforward bolting to standard pipeline flanges, ensuring a leak-tight seal and significantly reducing installation time compared to welded alternatives. Gaskets, typically supplied with the joint, are selected based on the service media to guarantee long-term sealing reliability.
