Million Swiss insulation joint large supply manufacturers

Million Swiss insulation joints Large supply of factory insulated joints are based insulating flange many problems that exist in the use of production practices while upgrading and updating of products, steel pipeline cathodic protection systems are necessary and important pressure piping components, extensive insulation joints cathodic protection systems applied to steel pipes. We produce insulated connectors according to the latest domestic and international standards, with a dual seal design, can not overcome the buried insulating flange, easy to leak, small rigidity, short life and other ills, to achieve a maintenance-free features buried the insulating joints Use the same period and the steel pipeline. Second, the product structure of the insulating joint is composed of the following parts: a sleeve, flange, lower flange, tube, down tube, seals, insulation, insulation coating. Insulating connector flange, a lower flange butt end unit, there are the seals and insulation, forming an insulating performance with dual seal structure. Sleeve groove weld or use two forms directly on the catheter and welding, the insulating member and the top tube, down tube is firmly sealed wrap to form a "sealed containers", which not only ensures good insulation effect, but also greatly enhance the bearing capacity of the insulation structure. Third, the quality requirements 1, insulation joint performance: 2.5KV shake table testing insulation resistance ≥200MΩ, breakdown voltage ≥3KV 2, the hydrostatic test pressure: 3 to 1.5 times the design pressure, tightness test pressure: design pressure equivalent to 4, non-destructive Detection: according to JB / T 4730-94 all butt joints 100% radiographic inspection, other pressure welds 100% magnetic particle inspection. 5, the groove: The API5L standard four, Technical Features 1, Dimensions: DN10 ~ DN3200 2, pressure rating: PN1.0 ~ PN40.0MPa 3, life: the same with the pipeline 4 Medium: natural gas, gas, gas , oil, water, chemicals, pulp suitable V. materials Features 1, insulation material: high-strength epoxy resin and glass fiber laminated composite materials: ASTM D709 G11 2, bending strength: Portrait ≥390MPa, lateral ≥290MPa 3, pull tensile strength: Portrait ≥340MPa, lateral ≥240MPa 4, compressive strength: ≥340MPa, water absorption: ≤30mg 5, after immersion in water resistance ≥5 × 108Ω, puncture resistance ≥35KV 6, a combination of steel body: 16Mn JB / T 4726 , ASTM A694 F52, F60, F65, F70, seven short diameter: L290, L320, L360, L390, L415, L450,16Mn, 20 #, API SPEC 5L X70, X65, X60, X56, X52, X46 8, seal Materials: O-shaped or U-shaped sealing ring: fluorine rubber, nitrile butadiene rubber, in line with ASTM D2000 9, filler: cold curable resin 10, an insulating coating: Imported liquid epoxy resin 11, anti-corrosion materials: thermal corrosion material 6, installation requirements 1, the insulating joint installed at 50 meters, to avoid the death of the mouth to be welded. 2, the insulation and pipes welded joints, the joint is not allowed within 5 m lift line. 3, insulation joints together with the pipeline pressure test. 4, insulation and pipe welding joints, should be connected to the requirements of mending, insulation joints are not allowed to make the surface temperature is higher than 120 ℃, anticorrosion. 5, insulating joints can be installed on the ground straight pipe. 6, insulation joint use of the ground installation and should be installed on the straight pipe from the elbow 20 meters away and set the bracket. 7. Avoid installing insulation joints on the riser. 8, underground installation should be avoided in the perennial water place.
