U.S. Bellows designed and fabricated two tied universal expansion joints for a pipe carrying sulfur dioxide. It is designed to carry hot gas that can be as high as one-thousand-twenty-two degrees Fahrenheit (1022°F).

Dual Interlocking Hinge Series. The DIH Series is designed for expansion joint openings with the ability to provide a smooth and virtually impact-free transition between opposing floor surfaces in addition to accommodating heavy rolling loads and multi-directional seismic movement. The dual interlocking center slide plates are hinged to allow the system to remain flush with finished floor surface.

The Tefbellows is an expansion joint that combines the properties of metal and PTFE into the most advanced expansion joint available for highly corrosive piping systems. Normal design temperatures are from -300F to +400F, and they will retain their pressure carrying capacity up to 1,200F in an upset condition, sufficient time for system shut ...

Expansion joints accommodate movement and absorb vibration in a piping system and, in doing so, they protect adjacent piping and equipment from damage. To make an expansion joint, we weld various end fittings on to a flexible bellows component. Relatively thin-walled tubing is used to form a single or multi-ply corrugated cylinder.

Pipe expansion joints are necessary in systems that convey high temperature substances such as steam or exhaust gases, or to absorb movement and vibration. A typical joint is a bellows of metal (most commonly stainless steel), plastic (such as PTFE), fabric (such as glass fibre) or an elastomer such as rubber. Most common types of expansion joints can be seen on Pentamet website.

Fabric expansion joints perform a function of compensating for duct misalignment and duct thermal growth typical in power plants and other ducting systems. Fabric expansion joints are …

Pressure Balanced Elbows are metal expansion joints which can consist of a single or double bellows in the flow section, and a balancing bellows of equal area on the back side of the elbow. Tie rods attach the outboard end of the balancing bellows to the outboard end of the flow bellows.

Metallic Expansion Joints. Metallic Expansion Joints are installed in pipe work and duct systems to prevent damage caused by thermal growth, vibration, pressure thrust and other mechanical forces. There is a wide range of metallic bellows designs in a variety of materials. Options range from the simplest convoluted bellows …

The universal pipe expansion joint consists of two bellows separated by a pipe section or spool. The primary purpose of this arrangement is to have a unit which will accept large amounts of lateral deflection. The amount of lateral deflection they can accept is a function of the amount of angulation each bellows can absorb and the distance between the bellows.

Vibration Isolation: unnecessary vibration in piping systems can cause severe damage to the system and surrounding equipment.; Wide Temperature & Pressure Rages: metal expansion joints can handle a wide range of hot and low temperatures, conveying liquids, solids and abrasive materials. They also offer high pressure ratings. Low Maintenance: Metallic expansion joints …
