Refineries, chemical plants, and oil & gas contractors across North India rely on seamless steel pipes for high-pressure fluid transport and process piping. RP Sales is a leading supplier of seamless steel pipes in Kanpur, sourcing from NABL-accredited mills and supplying with full mill test certificates and IBR documentation as standard.

Seamless Pipes vs Seamless Boiler Tubes

Seamless steel pipes (ASTM A106, API 5L) are ordered by NPS and schedule for fluid transport and pressure piping. Seamless boiler tubes (SA192, SA210, SA213) are ordered by OD and wall thickness for heat-transfer duty in boilers and heat exchangers. If your application is boiler or superheater service, see our Seamless Boiler Tubes page instead.

On-the-ground in Kanpur — where our seamless pipes actually land

Seamless demand in Kanpur is driven almost entirely by three clusters. Panki industrial estate — the heat-exchanger, boiler-ancillary and chemical-process fabricator belt behind the Panki Thermal Power Station — takes ASTM A106 Gr B and SA335 P11 / P22 in Schedules 40 / 80 / 160 for high-temperature steam, condensate and superheater spool work. Dada Nagar engineering shops on the city's west side run on A106 Gr B and A53 Type S in 1/2"–6" NB for pump-discharge headers, hydraulic-test-rig pipework and skid-mounted equipment fabrication; many of those buyers will only accept hot-finished material with a hydrostatic-test certificate against the rated schedule. The third stream is API 5L PSL2 line pipe for oil-and-gas EPC contractors who route mainline pipeline material through Kanpur for inland projects in eastern UP and Bihar — those orders ship against the buyer's ITP (inspection-and-test plan) and SOR (schedule of rates) with stage-wise inspection coverage by SGS, BV or a buyer-nominated agency.

Logistics inside Kanpur stays simple — Panki around 12 km, Dada Nagar around 8 km, with same-day or same-shift dispatch the standard commitment from the Bartan Bazar stockyard. For seamless we keep a dedicated bay layout that segregates by NPS and schedule, because a Sch 40 and Sch 80 in the same NPS look identical until you measure the wall — and an MTC-against-wall mismatch is the single most expensive mistake in seamless procurement. Freight on intra-Kanpur runs is rolled into the per-kg quote at a fixed last-mile rate. Payment terms map to the segment: Panki PSU-aligned fabricators run on 30-day post-dispatch credit against work-order cycles, often with bank-guarantee backing on IBR-coverage material; Dada Nagar OEMs move on monthly running-bill credit; API 5L EPC accounts run on milestone-tied progress payments against the work order with the ITP signed off. We surface the heat number on every cut piece and cross-reference it to the MTC on the dispatch challan — non-negotiable for any buyer who has been audited on heat-traceability.

Grades and specifications we supply

We stock and source seamless steel pipes across the full range of carbon steel grades used in Indian industrial procurement:

  • ASTM A106 Gr B/C — seamless carbon steel pipe for high-temperature refinery and power-plant service.
  • API 5L Gr B to X70 — line pipe for oil & gas transmission (PSL1 and PSL2).
  • ASTM A53 Type S Gr B — general-purpose seamless pipe for structural and utility use.
  • Sizes: NPS 1/2" to 24" in Schedules 40, 80, 120, 160, and XXS.

How wholesale pricing works for seamless pipes

Seamless pipe pricing is driven by the billet/coil rate from the source mill, the manufacturing route (hot-finished vs cold-drawn), and the grade and schedule. Our wholesale pricing is volume-dependent and transparent.

  • Prices are quoted per kilogram or per metric ton (MT).
  • Theoretical or actual weight basis is clearly stated in every quotation.
  • Significant freight advantages apply to full truckloads (9 MT to 30 MT).

FAQ

Which seamless pipe grades does RP Sales stock in Kanpur?
We stock ASTM A106 Gr B (high-temperature carbon steel), API 5L Gr B to X70 (line pipe), IS 1239 Part 1 (structural), SA335 P11/P22/P91 (alloy), and SA213 T11/T12/T22 (boiler). Sizes range from 1/2 inch to 24 inch OD with wall thicknesses from 2mm to 40mm.
Do you supply IBR-certified seamless pipes from Kanpur?
Yes. We supply ASME SA106, SA335, SA192, SA210, and SA213 seamless pipes with IBR Form III-C certification. All IBR material comes with stage-wise inspection reports, original MTCs, and heat number traceability as required by the Indian Boiler Regulations.
What is the difference between seamless and ERW pipes?
Seamless pipes are made from solid billets via the Mannesmann rotary piercing process — no weld seam. This makes them suitable for high-pressure (up to 10,000 psi) and high-temperature (up to 600°C for alloy grades) applications. ERW pipes have a longitudinal weld seam and are more economical for structural and low-pressure uses.
