Buy & Import Black Carbon Welded Steel Pipe from Tianjin Credit Import And Export Trading Co., Ltd. - Wholesale Supply

Tianjin Credit Import And Export Trading Co., Ltd. supplies black carbon welded steel pipes made from Q195 to Q345 carbon steel, with outer diameters from 15mm to 508mm and wall thicknesses from 0.5mm to 20mm. These are electric resistance welded (ERW) pipes, designed for low-pressure fluid transport, scaffolding, and structural framing. The pipes feature a smooth weld seam, no burrs at the ends, and are supplied in standard lengths of 5.8m, 6m, or 12m, or as custom-cut to order.

The material composition includes carbon content between 0.06% and 0.25% and manganese between 0.25% and 1.5%, consistent with Chinese GB/T 700 standards. Surface treatments include black paint, oil coating, or bare finish; galvanization and 3PE are available on request. The pipes are not heat-treated after welding, and mechanical properties are determined by the base material grade. These are structural-grade pipes, not pressure-rated for high-temperature fluid systems.

Primary buyers include construction firms in Southeast Asia, Africa, and Latin America for scaffolding, fencing, and low-pressure water lines. The pipes are also used in furniture manufacturing and mechanical frames. Packaging is in hexagonal bundles or loose stacks, secured with galvanized iron or plastic straps. Export is handled from Tianjin port, with standard trade terms FOB Tianjin. Lead time is typically 20 to 30 days after order confirmation.

Frequently Asked Questions About Black Carbon Welded Steel Pipe from Tianjin Credit Import And Export Trading Co., Ltd.
The supplier states the weld seam is smooth with no burrs, but does not specify inspection methods. Buyers should request a visual weld inspection report and request ultrasonic testing (UT) per ISO 17636 for seam integrity. A lack of UT data means the weld may not meet structural load requirements.

Sourcing Black Carbon Welded Steel Pipe from Tianjin Credit Import And Export Trading Co., Ltd. - China Import Guide

Verify the material grade (Q195 to Q345) and surface treatment before ordering. Request a material test report (MTR) that includes chemical analysis and mechanical properties. Do not assume compliance with EN or API standards unless the supplier provides a certified test report matching the exact standard. Confirm the pipe's intended use matches its structural or non-pressure rating.

Lead time is typically 20 to 30 days, but confirm with the supplier based on current production schedule. Export terms are usually FOB Tianjin, with payment via T/T or LC. Packaging must be secure to prevent deformation during shipping. Request a container loading plan and photos of packed goods before shipment to ensure bundle integrity and protection from moisture.

Upon arrival, inspect for surface rust, dents, or weld seam irregularities. Measure wall thickness at random points with an ultrasonic gauge. Check length accuracy and end squareness. Retain samples for third-party lab testing if used in load-bearing applications. Ensure documentation includes the MTR, packing list, and commercial invoice with HS code. Reject shipments lacking proper test reports.
