Long-term and reliable work requirements under the pipeline medium temperature, pressure, Nanjing Power Plant; electrically insulating properties of buried pipeline corrosion protection of electrical engineering required - new insulation and insulating flange joint structure (2) Three characteristics annex, there is sufficient strength and sealing performance; reasonable structure, assembly, disassembly, easy to replace parts. Fourth, the technical parameters - Temperature: ≤100 ℃, pressure range: Pn0.6MPa ~ Pn16MPa, product specifications: Dn50 ~ Dn1200 insulated joint is improved replacement for insulating flange in use according to the problems, accessory power plant, steel pipeline cathodic protection system is necessary and important pressure elements are widely used in cathodic protection system of steel pipes. Insulating joint reference foreign latest product structure, with a unique design to overcome the small insulating flange stiffness, easy to leak, it can not be buried, short life and other ills, realized buried maintenance features to make life and supporting insulated joints the same lines, 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, accessory power plant Xuchang, sandwiched insulation and seals form a double seal structure having insulating properties. In materials metal hose major parts of the austenitic stainless steel, thus ensuring the hose excellent heat resistance and corrosion resistance, the hose very wide operating temperature range, annex Hebei power plant for -196-600 degrees hose used by pipelines through the medium of corrosive select the appropriate grades, you can ensure that the corrosion resistance of the hose. 1. The overall use of 1Cr18Ni9Ti metal hose made of stainless steel, with strong corrosion resistance. 2. Hose body is thin-walled stainless steel tube hydroforming, with strong flexibility, high scalability, bending and vibration resistance, weaving nets of enhanced protection, so that it has a higher loading capacity. 3. The connection ends of the hose connections can also be made in addition to other threads, flange standard, easy connection and use. Special metal hose 4. The product is suitable not only for supporting the rotary joint, and is widely used to connect a variety of flexible delivery of the fluid medium. Corrosion, high temperature, low temperature (-196 ℃ ~ + 420 ℃), light weight, small size, flexibility is good. Widely used in aviation, aerospace, petroleum, chemical, metallurgical, power, paper, wood, textile, construction, pharmaceutical, food, tobacco, transportation and other industries.
