Rubber Expansion Joint,PTFE Expansion Joint,Metal Stainless Steel Expansion Joint Manufacturer

The rubber expansion joint can be as simple as a caulked separation between two sections of the same materials.In concrete and concrete block ("CMU") construction, the term applied is control joint, but serves a similar purpose.Expansion joints are cut into the concrete or asphalt to help with expansion and contraction of the material through the change in temperature, or due to movement of the road or bridge. The joints are cut into the structure at regular intervals to prevent it cracking or splitting.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, but flexible enough to accept the axial, lateral, and/or angular deflections.

What about Expansion Joint

An expansion joint is an assembly designed to safely absorb the heat-induced expansion and contraction of various construction materials, to absorb vibration, or to allow movement due to ground settlement or earthquakes. They are commonly found between sections of sidewalks, bridges, railway tracks, piping systems, and other structures.The expansion joint can be as simple as a caulked separation between two sections of the same materials. More recently, expansion joints have been included in the design of, or added to existing, brick exterior veneer walls for similar purposes. In concrete and concrete block ("CMU") construction, the term applied is control joint, but serves a similar purpose.

Metal Stainless Steel Expansion Joint

	JF-500 Stainless Steel expansion joint The newly developed product, JF-500 VERSA JOINT, can substitute the rubber vibration. In piping system, when consider the quality, character and economy of product. It can get best sffect to absorb the vibration and thermal expansion. 1.Absorbing in vibration and noise which making by pump and air compressor. 2.Connecting pipe line of ship engines' cooling system. 3.Air-Conditioning, Fire-Protection and steam system of piping. 4.General piping system.

	High temperature expansion joints Metal Stainless Steel Expansion Joints are designed for use in power,rifinery and cement plants that are mainly applicable to the high-temperature,medium-temperature and low-temperature hot air ducts,flue and air ducts as well as the pipelines with high-frequency vibration that are used to absorb axial,lateral or angular movements that occur at the same time.The expansions of the series are computer designed using EJMA standards as guidelines which are good at flexbility,resisting erosive,high temperature,long life and so on.
