Product Description
Since the steel pipe made of a single piece of metal has no joint on the surface, it is called a seamless steel pipe. The seamless steel pipe is a pipe having a hollow section and is used in a large amount as a conveying fluid. It can be used to transport oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, this seamless steel pipe has a lighter weight when the bending and torsional strength are the same.
There are no cracks, folds, rolling, separation and crusting defects on the inner and outer surfaces of our seamless steel tubes. And its wall thickness and outer diameter exceed the negative deviation.
Features:
The main feature of seamless steel tubes is that they have no weld seams and can withstand large pressures. The product can be a very rough cast or cold-draw.
Seamless pipe manufacturing process:
Hot rolling (extrusion seamless steel pipe): round billet → heating → perforation → three-roll cross-rolling, continuous rolling or extrusion → pipe removal → sizing (or reducing diameter) → cooling → straightening → hydrostatic test (or Flaw detection) → mark → warehousing
Uses:
1. There are many types of construction: underground pipeline transportation, groundwater extraction, boiler hot water transportation, etc.
2. Mechanical processing, bearing sleeves, processing machinery parts, etc.
3. Electrical category: gas transmission, water power generation fluid pipeline.
4. Anti-static tubes for wind power plants, etc.
