Import 38mm Welded Pipe — Buy in wholesale FOB from Supplier in China

This 38mm welded pipe is an electric resistance welded (ERW) carbon steel pipe manufactured by Tianjin Zhongchi Steel Co., Ltd. in Tianjin, China. The nominal 38mm outer diameter places it in the small-to-medium bore range for structural and mechanical applications, with the supplier specifying carbon steel or mild steel (MS) as the base material. Standard lengths are typically 5.8 to 12 metres in the industry, though buyers should confirm exact length availability and tolerance with this supplier. The pipe is produced by ERW, a process where steel strip is formed into a cylinder and welded longitudinally using electrical resistance heating, creating a forged weld without filler metal. The supplier indicates the pipe conforms to standards such as ASTM A53 or equivalent, though buyers should verify the specific grade and edition claimed.

The carbon steel composition provides mechanical strength for pressure and structural service, with mild steel (MS) grade offering good weldability and formability compared to higher carbon variants. Typical ERW pipe of this diameter in carbon steel will have wall thickness options ranging from 2.0mm to 4.0mm depending on schedule, though the exact schedule or wall thickness for this listing is not specified in the source. The supplier mentions protective coating for corrosion resistance, but does not identify the coating type, whether internal lining, external zinc, epoxy, or other system is applied. For water transmission applications, internal cement mortar lining or external polyethylene coating are standard protective measures in the industry. The weld seam in ERW pipe is typically trimmed flush on the internal surface, with weld integrity verified by ultrasonic or eddy current testing in mills following ASTM or API quality protocols.

Applications span construction scaffolding, structural frameworks, mechanical engineering, oil and gas gathering lines, water supply networks and general fabrication where consistent diameter and weld reliability are required. The 38mm size is commonly used as handrail tubing, conveyor roller shells, and in greenhouse construction in addition to fluid conveyance. Buyers should confirm the intended service, pressure rating and any required hydrostatic test certificates with Tianjin Zhongchi Steel Co., Ltd. The supplier offers FOB and CIF shipment terms according to the source, with L/C and T/T payment methods. No minimum order quantity is stated, though typical mill quantities for Chinese steel pipe exports range from one to several tonnes depending on specification complexity. Port of shipment would logically be Tianjin port given the supplier location, but this should be confirmed during negotiation.

Tianjin Zhongchi Steel Co., Ltd. is located at Shuangyao Village, Yangchengzhuang, Tianjin 301600, China, operating from the Tianjin municipality, one of China's major steel production and port regions. The supplier holds a harbor trust tier classification with a recorded response rate of 0.00 percent and zero average response hours, indicating no recent platform-mediated buyer interaction data. The company specialises in carbon steel welded pipe, with this 38mm welded pipe representing a standard product in their range. The proximity to Tianjin port provides logistical advantages for sea freight export, though the supplier does not disclose specific export volume, annual turnover, or market destinations in the available profile.

No information is provided regarding year of establishment, registered capital, production capacity, number of employees, factory certification, or quality management system accreditation. The supplier profile does not list client references, export history, or participation in industry trade fairs. Buyers should independently verify the company's business registration, production facility status, and whether they operate as a manufacturer, trading company, or hybrid entity. The stated willingness to offer FOB and CIF terms and accept L/C payment suggests some export experience, but this should be confirmed through direct communication and reference checks. Due diligence on Tianjin Zhongchi Steel Co., Ltd. should include verification of their ERW mill equipment capability, quality control procedures, and third-party inspection cooperation.
