Industrial Steel Pipes

Seamless & ERW Pipes in Stainless Steel, Carbon Steel & Alloy Steel — Manufactured as per ASTM, ASME & API Standards

ASTM / ASME / API

Product Overview

Steel Pipes

Pipes are customarily identified by "Nominal Pipe Size" (NPS), with Wall Thickness (W.T) defined by Schedule Number (SCH). We manufacture and stock Seamless & ERW pipes in Stainless Steel, Carbon Steel and Alloy Steel grades for Oil & Gas, Petrochemical, Power and Process industries.

FAQ

Frequently Asked Questions

Seamless pipes are manufactured without a weld seam by extruding a solid billet, making them ideal for high-pressure and high-temperature applications. ERW (Electric Resistance Welded) pipes are formed from a flat steel strip and welded longitudinally — suitable for low to medium pressure applications and are more cost-effective.

We stock stainless steel pipes in schedules: 5, 5S, 10, 10S, 20, 30, 40, 40S, 60, 80, 80S, 100, 120, 140, 160, STD, XS and XXS as per ASME B36.19 and B36.10 dimensional standards.

We supply ASTM/ASME A312 & A358 grades including TP304, TP304L, TP310, TP316, TP316L, TP317, TP317L, TP321 and TP347. Carbon steel grades include A53, A106 Gr. A/B/C and API 5L Gr. B.
