• As a leading exporter and supplier of chrome moly pipes in Saudi Arabia, we sell 5000 tons steel pipes per year, including the steel pipes for the high, medium and low pressure boilers. We specialize in selling chrome moly steel heat exchanger tubes, chrome moly steel boiler pipes, and high pressure chrome moly steel pipes in Saudi Arabia. In chrome moly steel, ASTM A335 P11, P22, and P91 pipes are used in power generation and in downstream oil and gas, while P5 and P9 grades are for refinery applications.

• With a collective experience of over 30 years, we have emerged as one of the largest just in time exporter of ASTM A335 P5, P9, P11, P22 and P91 chrome moly steel pipes to Saudi Arabia. Chrome moly steel pipes are used in the energy industry for high temperature and very low-temperature service (cryogenic), or for applications with very high pressures. ASTM A335 chrome moly steel pipes are used in conjunction with ASTM A234 WPx series buttweld fittings (WP5, WP9, WP11, WP22, WP91) and A182 Fx forged fittings and flanges (A182 F5, F9, F11, F22, F91). All these materials have similar chemical (Chrome, Moly, Nickel) and mechanical properties and can be easily welded and installed on site.

• We are devoted to provide the best solutions for our customers in Jubail, Yanbu, Jeddah, Riyadh and Dammam, the biggest industrial and commercial cities of Saudi Arabia. We have manufacturing set up, sales and export offices in both India and China to meet the immediate and long term chrome moly steel pipe requirements across the Kingdom of Saudi Arabia.
