Seamless Steel Pipe Price List (May 2026)

We list the bands below as indicative seamless carbon steel pipe prices for orders placed in May 2026, per ASTM A106 and API 5L, covering ASTM A106 Grade B and ASTM A53, and select IS 3589 grades. Seamless pipes are hot-pierced from solid billets and have no weld seam. Whether that process is required is a decision for the approved specification, drawing, and design calculation.

We quote per kilogram (₹/kg), ex-warehouse Kanpur, exclusive of the legally applicable tax stated on the current quotation. The quotation identifies mill origin against any approved-make list on your RFQ. For a firm delivered quote, submit your RFQ.

Why Seamless Pipes Cost More Than ERW

The Right Buyers for Seamless Pipe in Kanpur

Seamless pipe is one manufacturing option for services where the approved specification requires it. Process-heater, waste-heat-recovery, sugar-mill, chemical, compressed-air, and hydraulic buyers around Kanpur may call for A106 or another seamless grade. Schedule and manufacturing process are separate properties. Your engineer picks the grade, process and wall from the diameter, design pressure and temperature, joint factor, corrosion allowance, governing code and the project drawing. That call does not come from a generic economic threshold for ERW.

Do not upgrade or downgrade between ERW and seamless from price alone. Ordinary water and plumbing scopes may specify ERW, and so may fabrication work, while an applicable boiler-tube order may require SA192 or SA210 and the correct IBR dossier. Form III-B is for tubes. Form III-A is for pipes / steam piping. Form III-C is only for boiler mountings and fittings. Settle the product choice at ERW vs seamless or Sch 40 vs Sch 80, then see local supply at seamless pipes in Kanpur and seamless pipes in Lucknow.

Pipe RFQ Checklist: NPS, Schedule and Test Papers

Quotations for weldless pipe move on schedule and test papers more than on brand. State the items below and the quotation will be comparable across mills.

• NPS with schedule: nominal size plus Sch 40, 80, or 160. Schedule fixes the wall; NPS alone does not.
• Grade and spec: ASTM A106 Gr.B, ASTM A53, or the IS 3589 grade, with the edition year your consultant approved.
• Length: the required length. Single-random or double-random lengths are offered only when the quotation names them.
• End finish: plain ends for site welding or bevelled ends for butt-weld joints.
• Inspection documents: the required MTC fields, test results, heat traceability, and any IBR or project-specific certificate.
• Inspection: whether a named third-party agency will witness testing and loading at the point stated in the quotation.
• Delivery basis: ex-warehouse Kanpur, tax as stated on the current quotation, freight to the named site if quoted. A cut length is included only when the quotation names that work.

Worked Example: Sch 40 Against Sch 80 at 2 In NPS

A 2 in NPS pipe carries a 60.3 mm OD. In Sch 40 the wall is 3.91 mm; in Sch 80 it is 5.54 mm. The site weight formula, (OD minus wall) times wall times 0.02466, gives 5.44 kg per metre for Sch 40 and 7.48 kg per metre for Sch 80. A 6 m length therefore weighs 32.6 kg in Sch 40 and 44.9 kg in Sch 80. Apply the table bands: Sch 40 at Rs 80 to Rs 98 per kg puts one length at about Rs 2,610 to Rs 3,197. Sch 80 at Rs 95 to Rs 118 puts it at about Rs 4,265 to Rs 5,297. Both figures are ex-warehouse Kanpur before the legally applicable tax.

Watch the two different premiums. Per kilogram, Sch 80 sits about 19 to 20% above Sch 40 at this size. Per metre of installed pipe, Sch 80 costs about 65% more, because the thicker wall adds steel to every metre. Budget per metre, not per kilogram, when your BOQ lists lengths. Cross-check any size on the pipe weight calculator and the pipe schedule chart.

Common Procurement Mistakes on Seamless Orders

• Quoting NPS without schedule. A 4 in Sch 40 pipe and a 4 in Sch 160 pipe share an OD, but the site wall table and weight formula put Sch 160 at about 2.09 times the Sch 40 weight per metre. The schedule is what sets the price.
• Comparing per-kg rates across schedules. Sch 80 looks only 20% costlier per kg yet lands about 65% higher per metre at 2 in NPS. Price the lengths on your BOQ.
• Assuming an A106 offer carries an IBR dossier. Match the supplied component and approved specification to the applicable documents. Form III-B is the tube certificate.
• Assuming DRL availability. Double random lengths of 9 to 12 m cover select sizes only. Confirm with us before you plan fewer joints.
• Leaving traceability undefined. If the ITP requires pipe-to-heat mapping, put the marking and certificate fields on the PO and verify them before loading.

Standards and Compliance: A106, A53 and Schedule Walls

ASTM A106 covers seamless carbon-steel pipe for high-temperature service, with Grade B commonly quoted for process and power piping. ASTM A53 covers welded and seamless pipe for mechanical and pressure applications within its scope. Wall thickness follows the ASME B36.10M schedule system. At 2 in NPS, Sch 40 is 3.91 mm and Sch 80 is 5.54 mm. At 4 in NPS, Sch 40 is 6.02 mm and Sch 80 is 8.56 mm. IS 3589 covers steel pipes for water and sewage service in larger diameters.

For an applicable boiler pressure-part order, match the ASME grade and IBR paperwork to the component and project documentation schedule. Form III-B covers manufacture and test of tubes. Form III-A covers pipes / steam piping. Form III-C applies only to boiler mountings and fittings. You should not assume that ordinary A106 paperwork satisfies that requirement. Read the grade detail on our ASTM A106 reference and ASTM A53 reference, or compare grades at A106 vs A53.

Writing a Seamless-Pipe RFQ From Kanpur for UP Project Sites

If you are writing an RFQ from Panki, Dada Nagar, or the Bartan Bazar market area, you should send us the full line list, approved makes, inspection plan, required documents, and need-by date. Ask the quotation to separate offered NPS, schedule, grade, heat, length, and mill items from mill-procurement lines for that request.

Name the destination PIN on the RFQ if the load is intended for a site in Uttar Pradesh or a neighbouring state. Ask the formal offer to state whether that lane is offered, with vehicle and freight basis, dispatch estimate, transit basis, unloading responsibility, quote validity, and the documents supplied for each heat. If you need third-party inspection, name its witness or hold points before a loading date is agreed. Track sourcing context on the Kanpur steel market page.
