Black steel pipe for 21.3–508 mm outside diameters, DN25–DN500 sizes and a 6000 mm reference length. Grade, wall thickness, ASTM A106 applicability, end condition and MOQ are confirmed per order.
Source black steel pipe for projects that need a broad material and size selection. The black steel pipe covers 21.3–508 mm outside diameters, DN25–DN500 nominal sizes and a 6000 mm reference length. Grade, wall thickness, end condition and the governing standard are confirmed against the purchase order.
The range supports commonly requested carbon steel grades including Q195, A36, 20#, Q235B, 45#, Q345B, X52 and Q355B. The final grade depends on the design requirement and the applicable supply standard. Ask for the material route before ordering when the project specification names more than one grade. This makes the quotation easier to compare because the grade, size and document requirements stay in one written specification.
ASTM A106 appears in the requested product direction, but the applicable standard and product form must be confirmed per order. Black surface condition, production route, wall thickness and inspection documents should follow the approved specification rather than a catalogue assumption. Buyers should also confirm whether the order needs plain ends, bevelled ends, threads or another prepared condition before production starts.

Buyers can use the size range for industrial frames, general fabrication, fluid or structural project components where the engineering specification accepts the selected black steel pipe. The correct grade, wall and end treatment still depend on the service conditions. Send the working pressure, connection method or drawing when the pipe will serve a defined engineering function.
Confirm cutting length, end condition, bevel, threading, bundling and inspection requirements before production. When ASTM A106 or another named standard is required, send the complete material specification so the supply route can be checked before quotation. A drawing or cutting list helps the team confirm how each pipe length will be used. Confirm tolerance, inspection scope and marking requirements at the same stage.
Pipe is bundled for handling and shipment. Bundle marks, protection, loading method and container planning are confirmed with the order quantity, length and destination. The final packing plan follows the ordered diameter, length and handling requirements. This keeps loading details aligned with the confirmed shipment.
The reference range is 21.3–508 mm outside diameter and DN25–DN500. Confirm the exact size before quotation.
Q195, A36, 20#, Q235B, 45#, Q345B, X52 and Q355B are listed as requested options. Final grade depends on the approved specification.
ASTM A106 is included in the request, but the applicable product form and supply standard must be confirmed per order.
6000 mm is the reference length. Cut lengths or other requirements should be agreed before production.
Wall thickness is confirmed per order because it depends on the selected diameter, grade and project requirement.
Yes. Plain, beveled, threaded or another end condition can be reviewed against the purchase specification.
