Import Alloy Steel Pipe Reduer — Buy in wholesale FOB from Supplier in China

Cangzhou Weiheng Pipe Industry Co., Ltd. manufactures alloy steel pipe reducers in seamless configurations from 1/2 inch to 24 inch (DN15 to DN600) and welded configurations up to 100 inch (DN2500), with wall thicknesses spanning SCH5S through XXS. The reducers conform to ANSI/ASME B16.9 for factory-made wrought butt-welding fittings, with material options extending across carbon steel ASTM A234 WPB, alloy steel grades WP1 through WP91, and stainless steel grades 304 through 347H. For alloy steel applications specifically, the WP11 and WP22 grades provide chrome molybdenum chemistry comparable to ASTM A182 forged fittings, though reducers under A234 are wrought products rather than forgings, with corresponding differences in grain structure and mechanical property uniformity.

The seamless reducer range utilises hot-finished or cold-drawn pipe stock, with concentric and eccentric geometries available depending on pipeline layout requirements. Wall thickness schedules SCH40 and above address high-pressure hydrocarbon service, while the SCH5S to SCH10S range suits lower-pressure applications. Surface treatment options include transparent oil for short-term corrosion protection during storage, rust-proof black oil for extended indoor storage, or hot-dip galvanising for atmospheric corrosion resistance in non-process applications. The broad material matrix, spanning carbon, alloy, and stainless families, indicates a flexible manufacturing setup capable of sourcing multiple starting materials, though buyers must specify exact grade requirements rather than rely on generic alloy steel descriptions.

Primary applications cover petroleum refining, chemical processing, fossil fuel and nuclear power generation, gas transmission, and shipbuilding, where reducers transition between pipe sizes while maintaining internal flow continuity and minimising turbulence-induced erosion. The butt-weld end preparation per ASME B16.25 ensures compatibility with standard bevelled pipe ends. Buyers in the Middle East and Southeast Asian markets particularly favour Cangzhou-produced fittings for project work due to competitive pricing and established export logistics. Importers should confirm with Weiheng the specific alloy grade intended for their service, request impact test data for low-temperature design, and verify that the stated API, CCS, and ISO9001:2000 certifications remain current and scope-appropriate for reducer manufacturing.

Cangzhou Weiheng Pipe Industry Co., Ltd. is located in Wuliyao Development Zone, Yanshan County, Cangzhou City, Hebei Province, postal code 061300. This location places the company within the Cangzhou-Yanshan corridor, a region with dense concentration of pipe fitting and flange manufacturers serving domestic and export markets. The supplier holds a harbor trust tier classification, with a response rate of 0.00% and no recorded average response hours, indicating minimal platform-mediated communication activity.

The company presents itself as a manufacturer with broad material capabilities across carbon, alloy, stainless, and duplex stainless steel grades. The listing claims API, CCS, and ISO9001:2000 certifications, though it does not specify the scope of these certifications or provide certificate numbers for verification. No information is provided about year of establishment, factory floor area, annual production capacity, number of employees, major equipment such as induction bending or cold forming presses, or named domestic and international clients. Buyers must independently verify manufacturing credentials, inspect facilities where possible, and confirm that claimed certifications are current and cover the specific reducer products required.
