Product Description





Pipe joints which have the sealing performance , Strength properties and electric

 corrosion resistance of buried steel pipeline requirement, called insulating joint


it makes of insulating slab, sealing parts,insulating coating and short pipe ,

sleeve pipe etc. Between the two short pipes have one butt joint, 

the butt joint with sealing  and insulating parts which form the performance of insulation 

and double sealing structure. the sleeve pipe takes two kinds of welding ,

Groove welding and directly welding on guiding pipe,it makes insulating parts and 

short pipes fixed stably and be a "sealing capacity" to ensure the good insulating 

performance .meanwhile,it highly improves  the pressure-bearing ability. 

Insulating joint is the upgrading proudtcs  of insulated flange As the insulated flange 

have problem during the usage. 

insulating joint is the essential main pressured parts 

widely used in the Steel pipeline cathodic protection system.


Insulating joint should take overall extrusion welding form but not connect by bolts 

or flange. Our insulating joint adopt the forming which let the insulated parts 

and sealing materials inside with sleeve pipe . 

Fixing all the parts stably at its location after assembly.  

Under the earth pressure and stipulated pipe operating pressure go on hydro. test, 

the whole insulating joints keep complete fine.

 the sealing parts is closed to the insulating slad and have permanent elasticity.

meanwhile,the sealing element does not come into direct contact with the bare metal 

surface, to ensure the compactness of joint.

 Installation  Notice

Insulation joint installation place within 50 meters should not be allowed 

have welding die mouth.

After connection Insulation joint and pipeline , the pipe lifting  will be forbid within 

5 meters

When the insulating joint and pipe connection and do pressure test ,

the  speed of pressure increased should be less than 0.5MPa/min

After insulation joint and pipeline connection should fill the mouth as 

requirements,anticorrosion operation is not allowed  the insulation joint 

surface temperature higher than 

100 degrees

Insulating joint can be installed on the underground pipeline  

When install above ground , the insulation joint shall be installed on the straight 

pipe of 20 metres away from elbow and set up the stand

Avoid Insulating joint buried installation where the perennial stagnant water
