从China供应商批量进口90e(S)

The 90e(s) from Wenzhou Hezhong Steel Industrial Co., Ltd. is an industrial-grade butt-welding fitting or forged elbow component engineered for high-pressure piping systems in oil, gas, petrochemical, and power generation sectors. The designation suggests a 90-degree elbow in the short-radius (e) configuration with a specific schedule or end preparation denoted by (s), most commonly interpreted as a socket-weld or standard wall variant within Chinese industrial catalogues. Typical construction materials include ASTM A234 WPB carbon steel, A105 forged carbon steel, or 304/316 stainless steel, with wall thickness matching Schedule 40 through Schedule 160 depending on pressure class requirements. Nominal pipe size range generally spans from 15 mm (half-inch) to larger diameters, though exact stocked sizes require supplier confirmation.

Manufacturing follows hot-forming or forging processes with full penetration welds when supplied in welded construction. For carbon steel variants, post-weld heat treatment (normalising or stress relieving) is standard to meet NACE MR0175 for sour service environments. Surface finish is typically black-oxide mill scale for carbon steel, or pickled and passivated for stainless grades. End preparations include bevelled ends for butt-welding per ASME B16.9 or ASME B16.11, with bevel angles of 37.5 degrees plus or minus 2.5 degrees being the machining standard. Dimensional tolerances for wall thickness, outside diameter, and end-to-end length follow the relevant pipe fitting standard for the claimed specification class. The supplier indicates packaging in wooden cases, which is consistent with protecting machined bevels and threaded ends during ocean freight.

Buyers for this product are typically EPC contractors, refinery maintenance departments, and power plant procurement teams who require compliance with project material specifications. The Sinopec reference in the source description signals suitability for Chinese state-owned enterprise standards, which may include GB/T 12459 for butt-welding fittings or GB/T 14383 for socket-welding and threaded fittings. Import buyers should verify whether Wenzhou Hezhong provides mill test certificates with chemical composition and mechanical properties, whether the product carries API, ISO, or pressure equipment directive (PED) certification for European markets, and whether material traceability to heat number is maintained.

Wenzhou Hezhong Steel Industrial Co., Ltd. is located at No. 4846 Yongqiang Road, Haibing Street, Longwan District, Wenzhou City, Zhejiang Province, postal code 325024. Wenzhou is a major cluster for stainless steel pipe, fitting, and valve manufacturing in China, giving the supplier geographic proximity to raw material mills and downstream processing capacity. The supplier holds an imported supplier tier and harbour trust tier, with zero recorded response rate and zero average response hours. Buyers should therefore anticipate manual communication and build lead time for quotation into their procurement schedule.

The source description cites supply to Sinopec and other critical sectors, suggesting production alignment with Chinese state-owned enterprise procurement standards. No specific certifications, year of establishment, factory floor space, or workforce numbers appear in the available data. The description also references ISO and SGS certifications, but these should be verified directly with the supplier, including certificate numbers, scope, and validity dates, because the profile does not display scanned documents. Packaging in wooden cases is confirmed. Buyers should request a factory audit or third-party inspection report before placing large orders for critical infrastructure projects.
