Carbon steel insulating joint insulation joint stock manufacturer

Carbon insulation joint insulation joint stock steel manufacturers insulating joint is improved insulating flange according to the existing problems in the use of replacement products, steel pipeline cathodic protection system is necessary and important pressure element, is widely used in steel Cathodic protection system piping system. My company's insulating joint reference foreign latest product structure, with a unique design to overcome the small insulating flange stiffness, easy to leak, can not be buried, short life and other ills, realized buried maintenance features that make use of insulated joints the same life and supporting pipeline, monolithic insulating joints of the parts from the following components: the upper and lower tubes, sleeves, insulating parts, seals, insulation coating. In the joint on insulation, lower pipe butt end unit, sandwiched insulation and seals form a double seal structure having insulating properties. Technical characteristics: Dimensions: DN15 ~ DN1200 Pressure rating: PN1.0 ~ PN40MPa life: the same insulating pipe joints are indispensable accessory gas distribution pipeline and oil pipeline systems, mainly used in gas transmission and distribution systems and gas regulator stations, its role is to inter-segment between gas transmission and distribution pipelines, gas regulator stations and transmission and distribution lines are insulated isolation, protected from electrochemical corrosion and prolong life, but also directly buried underground. The company's monolithic insulating joints are in comparison with foreign products, analysis, focusing on basic research for the design of gas transmission and distribution pipeline leakage problems often occur. Insulating fittings for media: oil, gas, water, chemicals, pulp suitable insulating joint materials used satisfy the following requirements: sealing materials: O-shaped or U-shaped sealing ring: fluorine rubber, nitrile butadiene rubber, in line with ASTMD2000 . Filler: cold curable resin; insulation coating; imports of liquid epoxy resin; anti-corrosion materials: thermal corrosion materials; insulating materials: high strength epoxy resin and glass fiber composites - layered: ASTM D709G11. Bending strength: longitudinal ≥390MPa, transverse ≥290MPa; tensile strength: Portrait ≥340MPa, lateral ≥240MPa; compressive strength: ≥340MPa; water absorption: ≤30mg; resistance ≥5 * 108Ω breakdown voltage ≥35KV combined steel after immersion in water Body: 16Mn, JB4726, ASTM A694F52, F60 water pipeline insulation joints chemical attack if necessary, please call to discuss,
