The Meaning and Type of Steel Pipes

Steel pipe is a hollow tube with round cross section for the conveyance of products. It is widely used in construction industry, a variety of manufacturing and industrial applications. In plumbing systems, steel pipe can be used to transport liquids and gases for commercial and residential buildings, as well as in municipal water supplies.

The Steel Pipes Standard:

We mainly produce steel pipes according to ASME B31.3,MSS SP-25,ASTM A53,ASTM A106,ASTM A312,ASTM A530/A530A,DIN2448,API 5L,EN10025.

The standard ASME B31.3 requires random examination of materials and components to insure conformance to listed specifications and standards.

MSS SP-25 is one of the most commonly used standard. It contains a variety of specific marking requirements.

Standard ASTM A53 is used in producing pipe,steel,black and hot-dipped,zinc coated,welded and seamless.

Standard ASTM A106 is used in producing seamless carbon steel pipe for high-temperature service.

Standard ASTM A312 and ASTM A530/A530A for general requirements for specialized carbon and alloy steel pipe.

General steel pipe including types:

1.Longitudinally Welded SAW

2.Electric Resistance Welded (ERW)

3.Seamless

4.Casing Pipes

5.Cold Drawn Seamless Mechanical Steel tube and pipe

6.Hot Rolled Steel Pipes

7.Spiral submerged arc welding (SSAW) steel pipes

8.Tubing Pipes

Seamless pipe is made using a piercing rod, which gives the material a smooth and even finish with no joints. This product is the more expensive, but is also considered more reliable, especially in high pressure applications. Welded pipe is made from steel sheets that are rolled around a form, then welded shut along the joints. While welded steel pipe is less expensive, it is also more likely to fail, and can’t generally hold up well in high pressure uses.
