Rectangular Metal Expansion Joints

Talk To An Expert

Triad Bellows has years of experience designing and fabricating stainless steel rectangular bellows and expansion joints. Fabric joints are popular in many rectangular applications, but cannot operate properly under stressful, high heat conditions. Stainless steel bellows can be designed to accommodate for heat and pressure requirements, while still maintaining stated movements and cycle life.

Triad specializes in Rectangular Metal Expansion Joints with the trusted camera corner design. Our designs are in accordance with EJMA standards and can be made in an unlimited combination of metal bellows, flange and flow liner materials. Universal Rectangular Metal Expansion Joints provide increased lateral and axial movement. As with circular metal expansion joints, metal rectangular joints take up three types of piping movement: axial, lateral and angular. In order to properly design rectangular bellows, it is critical to know in which direction the lateral and angular movements will occur in relation to the long and/or short side of the bellows. EJMA 10th Edition data sheets are provided for all rectangular metal bellows expansion joint quotations.
