These types of expansion joints can be supplied with limit rods, liners, covers, rods, hinges or gimbals.
Weld end KB expansion joints are supplied with pipe connections in a wide range of carbon steel, stainless steel, and nickel alloy grades. The pipe dimensions can be manufactured according to international industry standards or customized to meet specific project requirements. With extensive manufacturing capabilities, KLINGER offers tailor-made solutions designed to suit demanding operating conditions.
These expansion joints are widely used across many industries and can be designed as either single or universal configurations, depending on the required movement and operating conditions. They are particularly well suited for high-pressure applications where welding is acceptable and leak prevention is critical.
Compared to flanged expansion joints, weld end designs offer a more economical solution, as they eliminate the need for costly flanges and gaskets. The welded connections provide a permanent, leak-tight installation with minimal maintenance requirements throughout their service life.
Benefits / Properties
Steel expansion joints utilize one or more flexible elements to absorb movements in piping systems caused by thermal expansion and contraction. The flexible element consists of one or more stainless steel bellows, with the material grade and design selected to match the specific application and operating conditions.
KLINGER Denmark can supply expansion joints in a wide range of material grades, including AISI 304, 316, 321, 310S, 904L, Duplex 2205, Duplex 2207, and more. Solutions are available with control rods, reinforcements, internal liners, and pressure-balanced bellows designs. Our specialists can advise on the optimal expansion joint solution and provide comprehensive documentation for the supplied equipment.
KLINGER Denmark supplies steel expansion joints with fixed flanges, loose flanges, weld ends, or threaded connections. You can learn more about the available designs and solutions on this page.
