Insulated joints for gas transmission and distribution and petroleum pipelines dedicated pipeline joints
Function or purpose: Insulating joint is a general term for pipe joints that have both the sealing performance, strength performance and the insulation performance required for electrical corrosion protection required for buried steel pipelines.
Product introduction: Insulating flange is a general term for pipeline flange joints that have both the sealing performance required by buried steel pipelines and the electrical insulation performance required by electrical corrosion protection projects. It includes a pair of steel flanges, insulation seals between the two flanges, flange fasteners and fastener insulation parts, and a pair of steel short pipes that have been respectively welded to the two flanges.
Insulating flanges and insulating joints are products produced by our factory for the petroleum and chemical industries for many years. It has simple structure, safe use and reliable performance, and has been widely used and well received.
Insulating flange is a general term for pipe flange joints that have both the sealing performance required by buried steel pipes and the electrical insulation performance required by electrical corrosion protection projects. It includes a pair of steel flanges, insulation seals between the two flanges, flange fasteners and fastener insulation parts, and a pair of steel short pipes respectively welded to the two flanges.
Insulation flange products have formed a series. When there are special circumstances, they can be designed and manufactured separately according to user requirements. Warmly welcome all users to choose our products.
Installation maintenance and instructions
1. There should be dead holes to be welded within 12 meters of both ends of the insulating joint and insulating flange installation.
2. Buried insulating joints should be located at the level of the pipeline, and should not be installed in low-lying places where water is accumulated throughout the year or the pipeline runs.
3. The installation position of the insulation joint and the insulation flange should be convenient for inspection and maintenance. The insulation joint and the insulation flange should be set outside the ESD valve block of the entry and exit station.
4. Insulated joints There should be a distance of 6 times the nominal diameter and no less than 3 meters between the insulating flange and the pipe fittings.
5. Insulating joints Insulating flanges should not be used as compensation parts for thermal deformation. When welding with the pipeline, it should be aligned with the pipeline, and the pairing should not be strong, and the weld should be free to expand and contract without obstruction. During field installation and welding, the temperature in the middle of the insulating joint and insulating flange should not exceed 120°C.
6. Insulated joint After the insulated flange is welded to the pipeline, the lower end should have a stable support.
7. Insulated joints The high-voltage surge protection of insulated flanges should be implemented in accordance with SY/T0086
8. Buried insulating joints can be landfilled only after passing the system pressure test and tightness test after being checked to be correct.
| Introduction | Pipe joints which have the sealing performance , Strength properties and electric corrosion resistance of buried steel pipeline requirement, called insulating joint | ||||||
| component | 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. | ||||||
| Advantage | 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. | ||||||
| working life | same with the pipeline | ||||||
| Applied Medium | Oil, air,water,Chemical,mineral | ||||||
| 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 | |||||||
