Black steel pipe from Beijing Metleader Pipeline Technology Inc. is manufactured to ASTM A53 Grade B and API 5L standards, with outer diameters ranging from 20mm to 508mm and wall thicknesses including SCH 10, SCH 20, SCH 40, SCH 80, and SCH 160. The pipe is uncoated, with a natural black oxide finish formed during hot rolling, offering mild corrosion resistance suitable for buried and above-ground applications. Lengths are supplied in 6-meter or 12-meter segments, with beveled or plain ends as standard, and end protection via plastic or iron caps.
The material is carbon steel with a typical composition of 0.26% carbon, 0.90% manganese, and trace elements as defined in ASTM A53. This grade is not heat-treated and retains its as-rolled microstructure, making it suitable for welding and threading. It is commonly used in low-pressure fluid conveyance systems such as water, gas, and fire sprinkler lines. The black oxide layer is not a coating but a byproduct of manufacturing; it does not provide long-term corrosion protection in highly aggressive environments.
Buyers in construction, municipal infrastructure, and industrial maintenance procure this pipe for its cost efficiency and compatibility with standard fittings. Shipments are bundled in 20-foot lengths and containerized for export, typically under FOB Tianjin or CIF terms. Minimum order quantities are not stated but are typically negotiated per project volume. Buyers should confirm end preparation and inspection certificates prior to shipment.

Before ordering, verify the material grade (ASTM A53 Grade B), wall thickness schedule, and end preparation type. Request a certified mill test report for each batch to confirm chemical composition and mechanical properties. Do not accept generic compliance statements. Confirm that the pipe meets the required standards for your application, especially if used in pressurized or buried systems.
Lead time is not stated but typically ranges from 25 to 45 days after order confirmation, depending on production scheduling. Payment terms are usually 30% advance and 70% against shipping documents. Incoterms are commonly FOB Tianjin or CIF destination port. Confirm the container loading plan, bundling method, and whether end caps are included. Request a packing list before shipment.
Perform visual inspection for surface defects, uniformity of black oxide, and end protection integrity. Use calipers to verify wall thickness against the specified schedule. Request a sample from each batch for destructive testing if the project demands high reliability. Ensure the supplier provides a signed inspection certificate and that all documentation is in English and matches the purchase order.
