For gas insulated connector factory, the insulating joint factory, the JY series insulating joint factory insulated joint is at the same time required sealing performance of buried steel pipeline, strength properties and electrical etching the required insulation properties of the pipe joints collectively. It contains the assembly of the insulating plate, packing, sealing rings, short tube. It is the alternative insulating flange. The structural properties of insulating joint overall extrusion welded, not bolted flange connection type. The insulating joint insulation and sealing materials folder and fixed in the sleeve (assembly) in the form of. Insulating joint after assembly to the internal components should be fixed in the corresponding position. Pressure in the soil pipeline operating pressure and in-plant or on-site pressure test of the entire insulating joints remain intact. The insulating joint sealing member abuts the connector internal insulation plate, having a permanently too elastic, and both surfaces of the sealing member is directly in contact with the bare metal surface does not move, to ensure the tightness of the joints. Features good insulation: 2500V shake table testing insulation resistance ≥ 200MΩ, the breakdown voltage ≥ 3KV. Long life: with the life of the pipeline, such as strength. High strength: the pressure ≥ 1.5PN test (design pressure). Use temperature: -30 ° C - +90 ° C. Applicable medium: oil, gas, water, chemical raw materials, coal slurry. Material characteristics: the materials used meet the following requirements: Insulation material: high-strength epoxy resin and glass fiber layered meet the material: ASTM D709 G11. Bending strength: ≥ 390MPa longitudinal, transverse ≥ 290MPa; Tensile strength: ≥ 340MPa longitudinal, transverse ≥ 240MPa; compressive strength: ≥ 340MPa; water absorption: ≤ 30 mg; resistance after immersion in water ≥ 5 * 108Ω breakdown voltage ≥ 35KV composite steel The body: 16Mn the JB4726, ASTM A694 F52, F60 short tube: 20 #, 16Mn, GB8163-99; X70, X65, X56, X52, X46, API SPEC.5L. Sealing materials: O-shaped or U-shaped seal ring: fluorine-containing rubber, nitrile butadiene rubber, and comply with ASTM D2000. Filling materials: cold curing resin; insulation coatings; imported liquid epoxy resin; corrosion-resistant materials: heat-shrinkable anti-corrosion materials; installation requirements: insulating joint installed at 50 meters, to avoid to be welded shut the mouth. Insulating joints and pipeline connection, and not in the joint lifting line 5 meters. Insulating joint pipeline equipment pressure test. Insulating joints and pipeline connection should be required to fill the mouth are not allowed to make the insulating joint surface temperature higher than 120 ° C, anticorrosion. 5 insulating joints can be installed in underground straight pipe. 6 the insulating joint ground-mounted, should be installed in just 20 meters away from the elbow segment and set the bracket. 7 insulation joints to avoid installed in the riser. Buried installation should be avoided installed at the perennial water.
