Seamless and welded steel pipes, carbon steel to super duplex
Seamless and welded, carbon to super duplex, ⅛" to 120" NPS, with 3.1 certificates.
Overview
We supply line pipe and process piping in the grades Pakistani oil, gas, fertilizer and power projects specify most: API 5L Grade B and X-grades for pipelines, ASTM A106 Grade B seamless for high-temperature service, A333 Grade 6 for low temperature, A335 P11/P22/P91 chrome-moly for steam, and A312 TP304/316 and A790 duplex for corrosive duty.
Pipe is sourced from approved mills in the GCC, Europe, Korea and Japan through our Dubai partner, with 3.1 mill test certificates, heat-number marking and third-party inspection where your purchase order requires it. Cut lengths, bevelled ends, galvanizing and 3LPE / FBE coating can be arranged before shipment.
Tubes for heat exchangers, boilers and instrumentation are available in A179, A192, A213 and seamless 316 instrument tubing.
Typical applications
- Oil and gas gathering and transmission pipelines
- Refinery and petrochemical process piping
- High-pressure steam and boiler piping
- Fertilizer plant ammonia and urea lines
- Cooling-water, fire-water and utility headers
- Heat exchanger and boiler tubes

Frequently asked questions
Seamless or welded pipe?
Seamless is specified for high pressure, high temperature and sour service, and for small sizes. Welded (ERW, LSAW) is economical in larger diameters for pipelines and water, and is accepted by API 5L with the appropriate weld testing.
Can you supply pipe with third-party inspection?
Yes. We arrange inspection at the mill or at the Dubai warehouse by your nominated agency, and include the inspection release note with the shipment.
Do you supply cut lengths and small quantities?
Yes, from single lengths for maintenance to full project tonnages.
