Product performance

The product is manufacture through welding or metal casting ,and the loosing part is sealed by echelon ring rubber .operated by gland and bolt and based on the principle of rubber’s elastic deformation under pressure ,the seal ring will be deformed and static seal will be done between joint body and expansion pipe wall .according to clients demand and product performance ,metal and seal ring materials will be selected strictly .high strength antifouling paint is painted outside and the joint bolt is made of high strength carbon steel or stainless ,since there is some space between body and expansion ,so axes and radial displacement will appear .inside pipe ,it become available to compensate and release pipe blind plate propulsion and make it easy to maintain and change pump and valve .therefore ,it is an ideal matching product for pipes’ installation and operation.

The metal expansion joint including the bellow product:

SSJB(gland loosing expansion joint)

Product installation note:

SSJB gland type loose tube expansion joint is suitable for both side and the pipe plug, without welding, organization is reasonable, reliable sealing, convenient installation.

SSJB-3(gland loosing stop expansion joint)

After installed on the pipeline ,tighten the nut elastic sealing ring ,under the action of nut gland ,rely on each other slope ,compression in the tube outer ring seal and connection function .when the temperature change can be in the middle of the joint pipe free of scale ,when the foundation sink ,the pipe can be skewed ,and ensure the sealing with no leakage ,thereby the purpose of automatic compensation.

Flange loosign expansion joint:

Flange loosing expansion joint is pumps, valve ,piping ,equipment and pipeline connection of new products, connected by the bolt ,making it a whole ,and has certain displacement ,so you can at the time of installation and maintenance ,according to the on-site installation size adjustment ,at work ,can put the axial thrust and also to the whole pipeline system ,so not only improve the work efficiency ,and cut the pump ,valve ,pipeline equipment play a protective role .

single flange loose set limit expansion joints 

single flange loose set limit expansion joints are metal products, which have superior high tensile and compressive strength, soft sealing performance, easy handling and other functions , is widely used in electric power, metallurgy, chemical industry, water supply and sewage treatment and other industries, a major role in the pump between the valves and piping connections. Single flange expansion joints have a certain role in the multi-displacement pipeline operation, the pipeline in operation due to the heating or cooling, crustal subsidence and stress have an important role in the expansion and contraction of compensation, so expansion joints can ease the pipeline running the blind thrust, the pipeline play a protective, especially for the installation and maintenance of the pipeline provides a great convenience.

Double-flange loosing-stop expansion joint

Double-flange loosing-stop expansion joint mainly applied to all kinds of residence, hotel buildings, factories and building plumbing ventilation pipes, as well as water supply and drainage, sewage treatment, petrochemical and industrial pipelines and metallurgy, industrial automation, military industry, aviation, shipbuilding and other fields.

Folding double-flange loosing force-transferring joint

Folding double-flange loosing force-transferring joint is make up of flange loose tube expansion joint and short of pipe flange and dowel screw components, can reduce the pressure of by fitting thrust and compensation pipeline installation error, double flanged joint force can’t absorb the axial displacement. Double flange dowel joint is mainly used for loose tube connection of pumps, valves and other accessories .double flange loose set of dowel joint is a loose set of expansion joint and short of pipe flange and dowel screw components, it can deliver the fitting of a pressure thrust and error compensation pipes can’t absorb the axial displacement. Important for pumps, valves, piping accessories such as loose tube connection.

Two-end flange limit expansion joint installed in some equipment’s one side such as the valve, water meter etc, in order to convince the installation, disassembly and maintenance, And for long distance pipeline caused by temperature difference of heat bilges cold shrink its role to ease . Due to expansion appliance has the good comprehensive performance, so it is widely used in chemical industry, building, water supply, water drainage, oil, light and heavy industry, freezing, sanitary, plumbing, fire protection, electric power and other infrastructure.
