Pipes

Pipe is a term generally used to designate a long hollow body used for conducting gases or liquids such as water, fuel, gas, steam, oil etc. Rourkela Steel plant's pipe mill produces two types of pipe viz. Electric Resistance Weld (ERW) in 8-5/8" outer diameter to 16" outer diameter sizes and Spiral Welded (SW) pipes in 18" outer diameter to 64" outer diameter sizes.

Both the ERW and SW pipe plants at RSP are authorised to produce line pipes with the API monogram under American Petroleum Institute standard 5L. API pipes are exclusively used for transmission of gas and petroleum products.

Pipes (both ERW and SW) other than API specifications are supplied in IS 3589, commercial quality and works tested to customers' specifications.

Pipes to IS 3589 grades are certified for hydrostatic test pressure, chemical and physical properties and are generally produced under the supervision of the plants' own internal quality control. These are used for erection, drainage, water supply, structural and mechanical uses, pilings, handling of coal and other solids in pulverised and powdery conditions.

Commercial quality pipes are arisings during production of API or IS 3589 grade pipes. These pipes are certified to hydrostatic test pressure equivalent to API-5L-Gr A.

Common Grades: IS 3589 (Fe 330 and Fe 410), Commercial Quality, API 5L PSL-1 (Grades A, B, X42/46/52/56/60/65/70) and API 5L PSL-2 (Grades A, B, X42/46/52/56/60/65/70).
