Big Size Welded Carbon Steel Pipe
This big size welded carbon steel pipe is manufactured in Tianjin, China, with an outer diameter range of 350 mm to 914 mm and wall thickness from 9.53 mm to 40 mm, suitable for heavy-duty applications such as boiler pipes, structural supports, and fluid transmission in energy and construction projects. The pipes are produced using cold-drawn techniques and are available in lengths of 6 to 18 meters to meet varied project requirements.
The material is low to medium carbon steel, a standard grade for welded pipes in industrial applications, offering reliable mechanical properties for high-pressure and high-temperature environments. The pipes feature a round section shape and are coated with 3PE (three-layer polyethylene) for enhanced corrosion resistance, a typical treatment for pipes used in oil and gas or water transmission.
These pipes are widely used in oil and gas pipelines, structural frameworks, and boiler systems, where strength, durability, and resistance to environmental factors are critical. Buyers often confirm the pipe’s compliance with API standards and its suitability for specific applications such as SSAW, HSAW, or DSAW, depending on the welding method.

Sourcing Big Size Welded Carbon Steel Pipe from Tianjin Xinyue Steel Pipe Group - China Import Guide
Before ordering, verify the pipe’s compliance with the required standards for your application, such as API 5L for oil and gas or ASTM A252 for structural uses. Request mill test certificates to confirm the material grade, mechanical properties, and chemical composition of the carbon steel.
For logistics, discuss Incoterms such as FOB Tianjin or CIF to your port, as these clarify cost and risk responsibilities. Lead times for large-bore welded pipes can vary based on diameter and wall thickness, so confirm production schedules and delivery timelines. Payment terms such as L/C or T/T should also be agreed upon to secure the order.
Quality checks should include dimensional inspections to ensure the outer diameter, wall thickness, and length meet the specified tolerances. Request documentation such as non-destructive testing (NDT) reports for weld integrity and coating thickness measurements for the 3PE layer. Arrange for third-party inspection if your project requires additional quality assurance.
