Steel Pipes

Carbon Steel Seamless Pipes

Carbon steel is a specialized steel alloy with a higher carbon concentration than typical steels, up to 2.5% carbon content compared to the usual 0.05–0.3%. This enhanced composition gives the material increased hardness, tensile strength, and wear resistance, making it ideal for industrial applications requiring durability and pressure resistance.

Reliable Steel stocks Carbon Steel Seamless Pipes in sizes ranging from 1/2″ to 56″, available in various wall thicknesses and pressure ratings.

  • Conforming Standards: ASTM A53 / A106, API 5L Gr.B PSL 1
  • Available Grades: Gr.B and others upon request
  • Field of Application: Transmission of liquids, air, and non-aggressive gases
  • Mill Test Certificates (MTCs): Available upon request

ERW (Electric Resistance Welded) Pipes

ERW pipes are formed by high-frequency resistance welding of steel coils and are ideal for medium and low-pressure applications. They are widely used in structural, mechanical, and general engineering purposes due to their cost-efficiency and uniform wall thickness.

  • Size Range: 1/2″ to 24″
  • Conforming Standards: ASTM A53 / A135 / A500
  • Grades: A, B, and custom grades
  • Applications: Water pipelines, scaffolding, fire protection systems, HVAC, and light structural works
  • Finish: Black, galvanized, or epoxy-coated upon request

SAW (Submerged Arc Welded) Pipes

SAW pipes are manufactured using a submerged arc welding process, offering excellent weld strength and high structural integrity. These are typically used for long-distance oil & gas transportation, piling, and large-scale infrastructure.

  • Type: LSAW (Longitudinal) / SSAW (Spiral)
  • Size Range: Up to 120″
  • Standards: API 5L, ASTM A252, ASTM A671
  • Grades: Gr.B, X42–X70
  • Coating: 3LPE, FBE, Coal Tar Epoxy on request

Casing Pipes / Tubes

Casing pipes are used in drilling operations to support well walls and prevent collapse. These are key in oilfield, geothermal, and water well applications.

  • Standards: API 5CT
  • Grades: J55, K55, N80, L80
  • Thread Types: LTC, STC, BTC
  • Applications: Oil well casing, water wells, borehole casing
