Product Parameter

SAE 1020 Precision Seamless Steel Pipe is made through bright annealing or special cold rolling processes.So SAE 1020 Precision Seamless Steel Pipe is a kind of seamless steel pipe which is designed with several advantages:

1.Inside and outside surface no oxide coating;

2. Bear high pressure, no leaking;

3.Surface smooth;

4.No reformation in cold bending, no cracks during flaring test, and flattening test.

5.Small tolerance ,within+/-0.05mm

Pipe Coatings & Finishes

Galvanized – Covered with a protective zinc coating on steel to prevent the material from rusting. The process can be hot-dip-galvanizing where the material is dipped in molten zinc or Electro-Galvanized where the steel sheet from which the pipe is made was galvanized during production by an electro-chemical reaction.

Uncoated – Uncoated Pipe

Black Coated – Coated with a dark colored iron-oxide

Red Primed – Red Oxide Primed used as a base coat for ferrous metals, gives iron and steel surfaces a layer of protection

Production Application

It is widely used for automobiles, motorcycles, electric power, machinery, hydraulic accessories, bearings, pneumatic components, oil cylinders, coal mines, transportation, boiler equipment, pipelines, engineering etc.
