PRODUCT DETAILS

ASTM a53 seamless pipe

APPLICATION

|

PRODUCT APPLICATION

1.Seamless steel pipe for general purpose

Material: rolled from ordinary carbon structural steel, low alloy structural steel or alloy structural steel, with the highest yield.

Main application: used for pipelines for conveying fluids (such as water, oil, natural gas) or as structural parts.

2. Classification by supply method

According to the specific use, the supply is divided into the following three categories:

a. Supply by chemical composition and mechanical properties

b. Supply by mechanical properties

c. Supply by water pressure test

Note: Seamless steel pipes supplied according to categories a and b must also be subjected to water pressure test if they need to withstand liquid pressure.

3. Seamless steel pipes for special purposes

Seamless steel pipes are also widely used in the following fields:

Boiler pipes
Chemical and power industries
Geological exploration pipes
Oil pipelines
Product advantages and characteristics
Hollow section design

Widely used for conveying oil, natural gas, coal gas, water and solid materials.

Compared with solid steel such as round steel, it is lighter in weight at the same bending and torsional strength, and is an economical and efficient cross-section steel.

Manufacturing structural parts and mechanical parts

Typical applications: oil drill pipes, automobile transmission shafts, bicycle frames, steel scaffolding for construction, etc.

When manufacturing ring parts, it can improve material utilization, simplify the process, and save costs and time.

PRODUCTION PROCESS

HOT-ROLLED SEAMLESS STEEL PIPE PRODUCTION PROCESS

Main process:

Round tube billet preparation and inspection
Heating: Heat the tube billet to the temperature required for deformation.
Piercing: Use a piercing machine to process it into a rough tube.
Three-roller oblique rolling, continuous rolling or extrusion: Further roll the rough tube into shape.
Tube stripping: Peel off the outer oxide scale to improve the surface quality.
Sizing (or reducing): Control the product dimensional accuracy.
Cooling: Cool the steel pipe naturally or forcefully.
Straightening: Correct the straightness of the steel pipe.
Hydraulic pressure test or flaw detection: Ensure that the pipe body has no cracks or other defects.
Surface treatment: Oiling for corrosion protection.
Marking and warehousing: Labeling and classified warehousing.

FEATURES

The diameter is generally greater than 32mm, and the wall thickness is 2.5-200mm.
Delivered in hot-rolled or heat-treated state.
The process is simple and efficient, suitable for the production of large-diameter and thick-walled pipes.
