Steel Pipe
Steel Pipe
Steel pipes are cylindrical tubes made from steel used in a wide range of industries for conveying fluids, gases, and solid materials. Known for their strength, durability, and corrosion resistance, steel pipes are fundamental components in infrastructure development, energy transportation, industrial processes, and architectural structures.
Whether you’re in oil & gas, construction, water supply, or manufacturing, steel pipes provide unmatched performance, safety, and longevity. Available in various grades, sizes, wall thicknesses, and finishes, they can be customized to meet the exact needs of any project.
Types of Steel Pipes
Seamless Steel Pipe
Seamless pipes are manufactured without a welded seam, making them ideal for high-pressure and high-temperature applications. They offer uniform strength and are widely used in oil & gas, petrochemicals, and power generation.
Key Features:
- No welding or joints
- Excellent strength and pressure resistance
- Superior dimensional accuracy
Welded Steel Pipe
Welded pipes are made by rolling steel sheets and welding them along the length. These are cost-effective and suitable for low to medium pressure applications. Types include:
- ERW (Electric Resistance Welded) Pipes
- LSAW (Longitudinal Submerged Arc Welded) Pipes
- SSAW/Spiral Welded Pipes
Key Features:
- Economical choice
- Available in large diameters
- Suitable for structural and utility use

- Alloy Steel: ASTM A335 (P1, P5, P11, P22, etc.)
- Stainless Steel: ASTM A312 (304/304L, 316/316L), A358
- Duplex & Super Duplex: UNS S31803, S32750
- Nickel Alloys: Inconel, Hastelloy, Monel
International Standards:
- ASTM / ASME
- API (American Petroleum Institute)
- EN / DIN / ISO
- JIS / GOST / BS
Each standard defines chemical composition, mechanical properties, testing methods, and dimensional tolerances.
Applications of Steel Pipes
