LIAOCHENG XINPENGYUAN STEEL PIPE USED:
Thick wall steel pipe English (Thick wall steel pipe) and the biggest difference between thin-walled steel tube in the steel tube wall thickness, generally speaking, thin-walled steel pipe cold drawing technology,
And thick wall steel pipe generally use hot rolling technology, if unit of measure is used to distinguish, so, it is generally believed that the wall thickness/diameter is equal to 0.02 is watershed, the thick wall pipe and thin wall steel tube wall thickness is thin wall steel tube/pipe diameter less than 0.02, is greater than thick wall steel pipe, on purpose, thin-walled steel tube used in pipeline.And thick wall steel pipe used in billet of hollow parts.Under pressure, and important use in the pipeline.
Thick wall steel tube is mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction.For liquid transportation, water supply and drainage.For gas, gas, steam, liquefied petroleum gas.For structure: piling pipe, bridge;Dock, road, building structural tube, etc.
LIAOCHENG XINPENGYUAN STEEL PIPE characteristic:
1) expressed in nominal pressure its rank or stipulation pressure temperature rating of the pipe, should be stipulated in the standard of the pressure temperature ratings are used as the benchmark, such as GB/T 17185;
2) in the standard rules only connected to its nominal thickness of straight pipe pipe fittings, as stipulated in the standard benchmark pipe level determine the applicable pressure temperature rating, such as GB14383 ~ GB14626.
3) in the standard only stipulated the dimensions of pipe fittings, such as GB12459, GB 13401, should pass the verification test to determine the pressure strength.
4), the other shall be in accordance with the relevant provisions of the pressure design or analytic method to determine its use benchmark.In addition, the determination of pipe strength grade shall be not less than the whole pipeline system may encounter in the operation of the pressure of the harshest conditions.
