Black Steel Pipes
EZ Steel Industrial Co., Ltd supplies black steel pipes made from carbon steel, conforming to ASTM A53, API 5L, and BS 1387 standards. The pipes are available in nominal diameters ranging from 1/2 inch to 24 inches, with wall thicknesses varying by schedule to suit pressure and structural requirements. These pipes feature a black oxide finish, providing basic corrosion resistance suitable for non-exposed industrial environments.
The material grade includes A53-A369, Q195-Q345, and ST35, which correspond to common mild steel compositions used in global piping systems. These grades offer tensile strengths between 335 MPa and 485 MPa and yield strengths from 205 MPa to 345 MPa, typical for carbon steel pipes in industrial applications. The surface finish is untreated, preserving the natural mill scale, which is standard for black steel and suitable for coating or welding applications.
These pipes are commonly purchased by contractors in oil and gas distribution, water supply networks, and structural framing projects. Buyers typically require batch certification for material traceability and dimensional tolerances per ANSI B36.10M-2004. Trade terms are flexible, with FOB and CIF options available, and minimum order quantities are negotiable based on vessel loading capacity and destination port.

Sourcing Black Steel Pipes from EZ Steel Industrial Co., Ltd - China Import Guide
Before ordering, verify the material grade, wall thickness tolerance, and hydrostatic test pressure with the supplier. Request certified material test reports (MTRs) for each batch, including chemical composition and mechanical properties. Confirm the pipe end preparation - plain or bevelled - as this affects welding procedures and installation time. Do not rely on generic compliance claims without documented proof.
Confirm the Incoterms (FOB or CIF), port of loading, and estimated lead time, which typically ranges from 20 to 45 days depending on order volume and vessel availability. Payment terms are usually 30% advance and 70% against BL copy. Ensure packaging is rust-inhibited and bundled with steel straps to prevent damage during transit. Request container loading photos before shipment.
Perform incoming quality checks using a caliper for diameter and wall thickness, and a hardness tester for tensile verification. Check for surface defects like seams, laps, or deep scratches. Inspect the MTR against the order specification. Ensure documentation includes commercial invoice, packing list, certificate of origin, and test reports. Retain samples for third-party inspection if the shipment is for critical infrastructure.
