Import Alloy Steel Reducer — Buy in Bulk from Supplier in China

WH-steel Co. Ltd. manufactures alloy steel reducers as concentric and eccentric pipe fittings in seamless sizes from DN15 to DN700 and welded sizes from DN200 to DN2000. The product line covers schedule classes from SCH10 through SCH160, XS, XXS and high thickness to 80 mm. Material grades include A234 WPB, WP5, WP9, WP11, WP22, A420 WPL3 and WPL6, A403 WP304/L and WP316/L, and A860 WPHY 42-46, 52-60, 65-70, with special alloys such as Monel, Inconel, Cu-Ni and duplex stainless steel available on request. Standards reference is ASME B16.9.

Concentric reducers maintain centreline alignment and suit vertical pump suction lines and compressor inlets where air or gas pocketing must be avoided. Eccentric reducers offset the centreline, used in horizontal piping to prevent liquid accumulation at the dead leg. The seamless construction suits higher pressure ratings and closer dimensional tolerances, while welded construction accommodates larger diameters and heavier wall sections where post-weld heat treatment controls residual stress. Face coatings include cement mortar lining, FBE (fusion-bonded epoxy) and galvanised hot-dip or electro-plating for corrosion protection in aggressive services.

Typical buyers include oil and gas pipeline contractors, petrochemical EPCs, power plant maintenance teams and shipyard piping fabricators. WP11 and WP22 grades serve high-temperature steam and hydrogen service; WP5 and WP9 suit refinery reactor outlets; WPL3 and WPL6 provide low-temperature toughness for LNG and cryogenic lines. The WPHY grades are high-yield carbon and alloy steels for offshore risers and transmission pipelines. Importers should specify end preparation (bevel angle, root face, land dimension), heat treatment condition and whether hydrostatic testing is included or extra.

WH-steel Co. Ltd. is located in Cangzhou City, Hebei Province, with a Beijing address also listed in its profile. Cangzhou is a recognised concentration area for Chinese pipe fitting and flange manufacturing, offering access to steel pipe feedstock from nearby mills. The supplier holds a harbor trust tier, yet its response rate is recorded at 0.00 percent with zero average response hours. Buyers should not rely on rapid quotation and should use multiple contact channels.

The listing describes a comprehensive alloy and stainless steel fitting range with ASME B16.9 coverage and special alloy capability. No factory area, employee count, annual output, ISO certification, API licence or named project references are stated. The dual-address format may indicate a registered office in Beijing and manufacturing in Cangzhou. Importers should verify the actual production facility, welding procedure qualifications, NDE operator certifications and whether the company is a direct manufacturer or a coordinated group of mills.
