DIN standard PN25 rubber expansion joints

DIN standard PN25 rubber expansion joints

 Technical Conditions :

Main feature:

1,Small volume, light weight, good flexibility, easy installation and maintenance

2,When installation can produce transverse and axial, angular displacement, not affected by pipeline impassability heart, thread unparallel limit

3,Work can reduce structure transfer noise, vibration absorbing ability

4,We developed the company in seamless pressure rubber joint, in high temperature resistance, acid and alkali resistant, oil resistant pipe more effectively prevent the corrosive medium to rubber joint wall erosion and improve the service life

5,Because of flexible rubber joint can be bent with good comprehensive performance, so it is widely used in chemical industry, building, water supply, drainage, oil, heavy industries, frozen, health, plumbing, fire control, electric power and other basic engineering.

Main connecting dimension

The application of our rubber expansion joint

Because the rubber joint has good comprehensive properties, 

so it is widely used in chemical industry, construction, water supply, drainage, circulating water,

oil, light and heavy industry, frozen, sanitary, plumbing, electricity and other infrastructure projects.

 fire protection, papermaking, pharmaceutical, petrochemical, shipbuilding, water pump, compressor, fan and other piping systems.

Installation Instruction of Rubber  expansion Joint

I. Installation over displacement limit is not allowed when installing the flexible compound rubber joint .

II. For ground-horizontally ,suspense and vertically installed rubber joints with over 1.0Mpa pressure,both sides of the pipeline shall have 

support or support bracket,to avoid fall or damage.

III.The force of fixing support or bracket shall be greater than the axial force of working.Otherwise the anti-fall devise is required .

IV. It shall install the GB/T9115.1(RF) standard flange(small diameter flange) when installing the corresponding flange of flexible compound rubber joints.The size of flange D2 and do shall not be too small for preventing the leakage of sealing face.

V. It shall screw down symmetrically and gradually when installing the flange screw of flexible compound rubber joint,To avoid the partly leakage or damaging the sealing face of the rubber joint.

VI. When the rubber joint is installed vertically or in suspense with over 1.0Mpa pressure ,the screw shall be installed with gasket for preventing partly leakage due to loosened screw.

VII.The flexible compound rubber joint shall have fixing support when vertical installation is made .Heavy press on the rubber joint is forbidden .
