There are six types of pipes and tubular goods.
- 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.
- 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 etc. grades. They represent 21% of all tubular products.
- 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. OCTG represent 35% of all tubular goods.
- Pressure Tubing: used for industrial and pressure application. Pressure tubing are produced using seamless manufacturing. They represent 2% of all tubular goods.
- Mechanical tubing: used for mechanical and structural application and is produdced by ERW and seamless manufacturing. They conform to ASTM specification. Mechanical Tubing represent 17% of all tubular goods.
- 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. They represent 15% of all tubing goods.
