ERW Straight Seam Steel Pipe
The ERW steel pipe is short for electric resistance welded pipe. The project adopts the one time row roller forming technology of German. In order to guarantee the high quality, we use the digital regulation of electrical equipments provided by German Siemens and England MENT to control the manufacture. According to the standard of the contract, we provide steel pipes with high reliability and stability by using comprehensive tests, such as hydrostatic test, on line ultrasonic test, eddy current test, and physical and chemical test.
The ERW straight seam steel pipe (electric resistance welded pipe ) is widely used in petroleum, natural gas, steam, and the running pipeline of low-pressure flammable fluid. With a widen usage in petrochemical engineering, building of steel structure, electric power, boiler, supply of heat, coal mine, war industry, etc., the products are sold through the whole country from north to east, and also exported to America, Singapore, Bengal, German, Korea, etc.
Main Components of ERW Steel Pipe:
ERW steel tube uses the hot rolled coils as its raw material.
Feature of ERW Steel Pipe:
With a standard manufacture process, the products can be used in any standard range. Compared with the common welded pipe technology, ERW steel pipe is welded through the alternating-current resistance, and the welded joint is melted from the ontology mental base which makes the mechanical strength is much better than the general one.
1.It is applied in accordance with the customer's specific circumstances.
2.For fear of rusting in the long time ocean shipping, the steel pipes are all sprayed anticorrosive paint before exporting.
