As a leading exporter and supplier of alloy steel or chrome moly pipes in Singapore, 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, alloy steel boiler pipes, and high pressure alloy steel pipes in Singapore. In alloy 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 alloy steel pipes to Singapore. Alloy 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 alloy 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 Jurong East, Kampong, Woodlands, Ang Mo Kio, Pasir Ris, Bukit Batok, Choa Chu Kang and Paya Lebar, the biggest industrial and commercial cities of Singapore. We have manufacturing set up, sales and export offices in both India and China to meet the immediate and long term alloy steel pipe requirements across the Republic of Singapore. We aim at offering high quality but competitive price chrome moly pipes for our global customers.

ASTM A335 is a standard specification for seamless ferritic alloy-steel pipe for high-temperature service. The specification generally covers “chrome-moly” seamless pipes with remarkable resistance to corrosion and good tensile strength at high-temperature service. The testing requirements for these pipes include the following:

Transverse/longitudinal: tension and flattening, hardness, bend tests- for material which has been heat-treated in batch furnaces, these tests shall be made on the 5% of the pipes from each heat lot number. For smaller lots, one pipe at a minimum has to be tested
ASTM A335 Gr. P91 shall have a hardness of 250 HB / 265 HV (25 HRC)
Hydro testing: shall be applied to every length of pipe
The non-destructive electric test is optional
