Pipe Grade Table.jpg

We supply steel pipes by "nominal pipe size" in sizes from 1/8" to 100". The two most common types of pipes are welded pipe and seamless pipe. Both are available in carbon steel and stainless steel. Welded pipe is also called ERW (Electric Resistance Welded) pipe. The most common specification for welded carbon steel pipe is A53. The most common specification for seamless carbon steel pipe is A106B. 

There are six types of pipes and tubular goods.


  1. Standard Pipe: There are three different types of standard metal pipes - welded (ERW Pipe), seamless pipe, and galvanized pipe. They represent 10% of all tubular products.

  2. Line Pipe: Used primarily in Oil and Gas Applications. Line pipe includes ERW, FW, SAW and DSAW Pipe. They are manufactured to API 5L Specification and are available in X42, X50, X60, X70 etc. grades.

  3. Oil Country Tubular Goods (OCTG): This includes drill pipes, tubing and casing. It is used in drilling and completion of Oil and Gas wells. OCTG are produced by ERW and Seamless manufacturing.

  4. Pressure Tubing: used for industrial and pressure application. Pressure tubing are produced using seamless manufacturing.

  5. Mechanical tubing: used for mechanical and structural application and is produced by ERW and seamless manufacturing. They conform to ASTM specification.

  6. Structural Tubing: used for support or retention purpose. This tubing can be round or square and are produced by ERW manufacturing. They are used for fences, construction and other misc. support needs.
