Seamless Pipe Price
Price range for seamless pipes is ₹80-₹350 per kilogram in India and $1.10-$4.50 per kg in the US. Carbon steel is the cheapest, whereas stainless and alloy steels cost more depending on thickness and order volume. Indicative pricing varies significantly based on grade, specification (ASTM/API), size, and quantity. Contact us for project-specific quotations
Seamless Pipe Grades
The table below provides a full description of the standard material grades and their particular qualities.
Carbon Steel Seamless Pipes
ASTM A106/A53 pipes provide exceptional durability for high-temperature and high-pressure refinery service, creating a dependable and cost-effective industrial piping solution.
Stainless Steel Seamless Pipe
These 300-series grades offer exceptional corrosion resistance and hygiene, serving chemical processing, food preparation, and hazardous maritime environments perfectly.
Alloy Steel Seamless Pipes
These chromium and molybdenum-enriched tubes power difficult thermal conditions and high-pressure steam generation in power plants where standard carbon steel fails.
MS Seamless Pipes (Mild Steel)
A low-carbon variant valued for its ductility and ease of fabrication, which is widely used in low-pressure fluid conveyance and general mechanical applications throughout domestic infrastructure.
Seamless Pipe Types
Listed below are the types of seamless pipe that we provide, categorised by the material and manufacturing procedure.
Cold Drawn Seamless Pipe
Hot Rolled Seamless Pipe
Seamless Pipe Industrial Applications
Seamless pipe finds use across 6 major industrial sectors where pressure, temperature, or corrosion resistance is critical.
Oil & Gas Industry
Seamless carbon steel pipe and API 5L line pipe transport crude oil, natural gas, and refined products in upstream and midstream operations.
Power Generation
Thermal power plant boiler tubes and superheater piping use alloy steel seamless pipe (ASTM A335 P22, P91) for high-temperature performance.
Chemical & Petrochemical Processing
TP316L and TP321 stainless seamless pipe is used in refineries and chemical plants to transport corrosive acids, solvents, and process fluids.
Construction & Structural
Structural seamless steel pipe per IS 3589 and EN 10210 supports load-bearing columns, piling, and mechanical frameworks.
Boilers & Heat Exchangers
Seamless tubes conforming to ASTM A179 and ASTM A192 are specified for heat exchanger bundles and high-pressure boiler circuits.
Hydraulic & Mechanical Systems
Cold-drawn seamless pipe with tight OD and ID tolerances serves hydraulic cylinders, pneumatic systems, and accurate mechanical assemblies.
Seamless Pipe vs Welded Pipe
The table below contrasts seamless and welded (ERW) pipes across essential criteria to assist consumers in selecting the appropriate product form.
| Parameter | Seamless Pipe | Welded (ERW) Pipe |
|---|---|---|
| Weld Seam | None | Longitudinal weld present |
| Strength | Uniform throughout | Slightly weaker at weld zone |
| Pressure Rating | Higher | Lower for equivalent size |
| Surface Finish | Rougher (mill finish) | Smoother |
| Dimensional Tolerance | Wider | Tighter |
| Cost | Higher | Lower |
| Availability | Limited to 24" NB typically | Available in larger diameters |
| Best For | High-pressure, high-temperature, critical service | Structural, low-pressure, general purpose |
