Import Astm A53 Seamless Steel Pipe Wholesales — Buy in wholesale FOB from Supplier in China

HEBEI JINSHENG PIPE FITTING MANUFACTURING CO., LT supplies ASTM A53 seamless steel pipe in carbon steel, conforming to both ASTM A53 and ASME SA53 standards with availability in Grade A and Grade B for high-pressure service. The pipe covers NPS 1/8 through NPS 26 with Schedule 40 and Schedule 80 wall thicknesses, offering seamless construction that eliminates longitudinal weld seams. Mill standard packaging ships in bundled or loose formats, with sourcing from verified mills in China, India, and Turkey referenced for export trade. The seamless manufacture provides uniform circumferential strength and enhanced resistance to pressure and stress compared to welded alternatives.

Schedule 40 and Schedule 80 denote standard wall thickness dimensions, with Schedule 80 providing approximately double the wall thickness and pressure rating of Schedule 40 for the same nominal pipe size. Grade B seamless pipe withstands higher mechanical loads than Grade A, making it the default selection for most structural and pressure applications unless cost or weldability drives Grade A preference. The carbon steel composition responds to standard welding procedures with appropriate preheat control, and the absence of a weld seam removes heat-affected zone concerns that complicate welded pipe fabrication. Corrosion resistance relies on mill scale, protective oil, or buyer-specified coatings, as ASTM A53 does not mandate protective finishes beyond the black or hot-dipped galvanized options.

The pipe serves oil and gas transmission pipelines, water supply infrastructure, structural piling foundations, and general mechanical plumbing systems. Typical buyers include petroleum engineering contractors, municipal water departments, construction consortia, and industrial fabrication workshops. Trade terms referenced include FOB and CIF, with payment through L/C or T/T negotiable with the supplier. Buyers should confirm current stock availability, exact dimensional requirements including length random or fixed, and whether supplementary testing such as Charpy impact or hardness testing is required for the intended service environment.

HEBEI JINSHENG PIPE FITTING MANUFACTURING CO., LT operates from Wuliyao Industry Zone, Yanshan County, Cangzhou City, Hebei Province, China, a region with established concentration of pipe and fitting manufacture. The supplier holds an organic tier classification with a voyage trust tier designation. Response rate shows 0.00% with zero average response hours, indicating no active engagement metrics are visible. The company markets under the JSFITTINGS brand and presents itself as connecting buyers with verified mills across China, India, and Turkey for ASTM A53 seamless steel pipe supply.

The custom specification cites availability from multiple origin mills, suggesting trading or aggregator activity rather than exclusive own-mill production. No manufacturing capacity, year of establishment, employee count, revenue, or specific mill accreditations are disclosed in the available profile. The reference to flexible MOQ and shipping options appears in the source material, though buyers should confirm current figures directly as these are subject to change. The organic tier and voyage trust designation indicate some level of platform recognition, but buyers should independently verify quality system certifications and inspect mill relationships before order commitment.
