A pipe bellows are a major part of the expansion joint system. A rubber expansion joint can absorb vibration, some misalignment, and handle axial and limited lateral movement. A metal expansion joint uses bellows in the pipe system. The metal bellows handle thermal growth and pressure thrust. When a piping system gets warm the thermal dynamics ...
Expansion Joints. Expansion joints contain either one or multiple flexible elements to compensate for dimensional changes, which may be caused by thermal expansion or contraction of a pipeline, duct or vessel. Bellows type expansion joints, a "specialty" of KLINGER, are characterized by being virtually maintenance-free.
Ultralon expansion joints can offer working temperatures from -300°F to +400°F, and a choice of bellows rated for working pressures of 50, 150, or 300 psi. Gimbal, hinged, dual externally pressurized, and pressure balanced styles are construction options. Flanges are available in carbon steel, stainless steel, or Teflon coated.
expansion joints decouple vibrations and structure-born noise from diesel engines, turbines, pumps and compressors, preventing their transfer to the continuing lines. At the …
Make the piping systems fit the expansion joint. By stretching, compressing, or offsetting the joint to fit the piping, the joint may be overstressed when the system is in service. It is good practice to leave one flange loose until the expansion joint has been fitted into position. Make necessary adjustment of loose flange before welding.
Slip type (Dresser® Style) pipe expansion joints are used when the primary problem is a large axial movement. Materials can be selected to accommodate high temperatures and pressures. Design details include …

Expansion Joints - TEGUFLEX®. A wide range of moulded standard bellows up to 1000 mm with a large variety of rubber linings to meet almost all kinds of medium. Easy to install with good performance and long service life. Go to Customized Expansion Joints.
Toroidal pipe expansion joint may consist of one convolution or multiple convolutions. This joint is also known as an Omega bellows pipe expansion joint for it resembles the Greek letter Omega. Most toroidal bellows are hydraulically formed which requires high pressure. Others are free-formed, similar to blowing up a balloon.
Liners: A240-T304. Covers: Carbon steel. Tie Rods, Hinges, Gimbals: Carbon steel. The universal pipe expansion joint consists of two bellows separated by a pipe section or …
To call pipe bellows a Flexible bellows, maybe a stretch. That is an expansion joint joke or pun. Expansion Joints can be made of metal or rubber. A different type of expansion joint is used in concrete to allow the expansion of pouring foundations, sidewalks, streets, and driveways. The concrete exposition joints have nothing to do with pipe ...
Precompression of the Expansion Joint must be made as per instructions above. All anchor bases, anchors, and guides must be installed and secured to some rigid part of the installation. Only after these instructions have been complied with, can Bellows Systems Expansion Joints be hydrostatically tested at 1-1/2 times their rated working pressure.
In a piping system a Expansion joints alternately known as Bellows are like sealed springs. Sealed because it is required to contain the fluid pressure which is flowing …

The gimbal pipe expansion joint is basically the same as the hinge type, except that instead of being limited to deflection in only one plane, it can accept bending or angulation in any plane. It contains two sets of hinge pins or pivots, the axis of each set perpendicular to the other. Each set of pins is connected to each other with a central ...
A typical type of expansion joint for pipe systems is a bellows which can be manufactured from metal (most commonly stainless steel), plastic (such as PTFE), or an elastomer such as rubber. A bellows is made up of a series of one or more convolutions, with the shape of the convolution designed to withstand the internal pressures of the pipe ...
