Product Description
The insulation joint we produce has obtained a national patent (No. ZL 032135939), passed ISO9001-2000 International Standard Quality System Certification, ranked as recommended products by China Petrol-Chemical Group, and successively obtained physical market entrance permissions awarded by major oil fields within nationwide. The insulation joint is of sealing performance and strength capability required by buried steel pipeline and insulating property required by electrical corrosion, which consists assembly, insulating plate, filler, seal ring, nozzle stub, etc. The insulation joint is the replacement of insulating flange. The insulation joint adopts integral extrusion welding but not bolts or flange connection, clasping and fixing the insulation and sealing materials into the barrel (which is the assembly).
Features of insulation joint
1. Good insulating property: 100V megger test insulation resistance ≥10MΩ, breakdown voltage ≥3K.
2. Life Time: The same life time and equal strength with the pipeline.
3. Strength: Pressure test ≥1.5PN (Design Pressure)
4. Application Temperature: -30 centigrade to +90 centigrade
5. Applicable Medium: Oil, gas, water, chemical materials, CWM, etc.
