Cast iron expansion joints Specifications | Zhidan cast iron expansion joints | Shaanxi three super pipe

 Piping expansion joints should choose a reasonable expansion joints. The most widely used particularly harsh conditions of high pressure and temperature in the heat pipe conduit, the use of heat pipe expansion joints is an inevitable choice, because the heat pipe expansion joints made of steel manufacturing, can effectively resist the high temperature of 500 ℃ products. Good high-temperature medium in the pipeline transportation, thermal expansion and contraction issues high temperature heat pipe expansion joints of steel pipes in the heating and cooling time is the best solution, it has the characteristics of other types of high temperature expansion joints do not have. Steel expansion joints also has anti-aging anti-corrosion characteristics of good manufacturing process can be used for more than 10 years, when the annual maintenance need only re-painted rust treatment, aging effects of corrosion for expansion joints is very small. Telescopic gland using its own seal, widely used in the marine pipeline connection, both ends of the tube inserted into the gland and tighten the bolts can be used for compression of the gland seal both ends of the rubber expansion joints of cast iron Price, pipeline tight seal reliable connection. Is the best way to quickly connect pipes and solder joints and clamps compared to simple, fast and effective seal where to sell cast iron expansion joints, and allow the pipe is connected to the displacement of the rigid connection becomes flexible connection. Ductile iron casing expansion joints and expansion joints to make the same use of effective thermal steam turbine power plant circulating water piping in the circulating water pipe heating and reflux for use. Steel expansion joints high temperature can effectively ensure the operation of the circulating water pipe. Expansion joints installed in the stopper. So expansion joints used to effectively limit the use of their own role in the process of using the pipeline to prevent axial tensile force Rato free expansion in the range of designs, compensation. Pipe expansion joints in pressure test and pass through the wall plate, when practice basis: (1) the installation of expansion joints pipeline connection using hot melt connection between the same kinds of PP-R pipe material, Concealed threaded section may not appear. flange connection. hot melt connection is a physical process, applicable to the same kind of thermoplastic polyolefin material. The molecular chain of the original material Claudin melting bifurcation, a certain heating time, the two members connected and fixed iron specification sealer, establish joint pressure in the fusion zone. due to the joint pressure of the molten material is cooled with the molecular chain, the temperature dropped to reconnect, so two members are closed as a whole. melt melt connection into butt, socket Thermoplastic connection and fused connection should be used in building water supply pipeline pressure test mode after two (2) pipe cold water pipe test pressure of 1.5 times the working pressure of the piping system, but not less than 1.0 MPa;... the hot water pipe test a pressure of 2 times the working pressure of the piping system, but not less than 1.5 MPa. (3) pipe wall, plate, when practice base when hot water pipes through the wall, should be set up with the civil steel casing, the cold water pipe through the wall can be Reserved hole, the hole size than the outer diameter of 50 mm; cast iron expansion joints, the pipe should be set through a floor or roof steel casing, casing above the ground 50 mm, and take strict measures water; pipeline expansion joints through the foundation wall , should be set up metal casing above the foundation wall holes reserved spacing distance of not less than 100mm cast iron casing expansion joints specifications |.
