Carbon Steel Pipe Supplier
Bao Steel supplies carbon steel pipe and tube for fluid transportation, structural fabrication, piling, mechanical use, construction projects, equipment frames and steel distribution. Send your pipe standard, OD, wall thickness or schedule, length, steel grade, pipe type, end finish, surface treatment, quantity and destination so we can check stock, production route, MTC, packing and shipment details before quotation.
Choose the Carbon Steel Pipe Type That Matches Your Application
Carbon steel pipe quotation depends on more than OD and wall thickness. The correct route should match pipe standard, manufacturing method, pressure or structural use, end connection, surface treatment, packing method and inspection requirement.
Seamless Carbon Steel Pipe
For higher pressure, mechanical, boiler, oil and gas or applications where welded seam route is not suitable.
Request Seamless Pipe Quote →ERW Carbon Steel Pipe
For general fluid pipe, structural tube, fabrication, scaffolding, machinery frames and commercial pipe supply.
Request ERW Pipe Quote →LSAW / SSAW Steel Pipe
For large diameter pipe, piling, water projects, structural columns and long-length project pipe supply.
Request Large Pipe Quote →Square & Rectangular Tube
For steel structures, frames, racks, equipment bases, construction parts and fabrication projects.
Request Tube Quote →Carbon Steel Pipe Orders Need Standard, Route and End-Use Confirmation
Many pipe inquiries lose time because the buyer only sends a diameter and quantity. A workable quotation should confirm whether the pipe is for pressure service, structural use, piling, fluid transportation, mechanical fabrication or resale inventory.
Standard and Grade
Confirm ASTM, API, EN, JIS or GB route, plus grade requirement, MTC acceptance and inspection document needs.
OD and Wall Thickness
Send outside diameter, wall thickness or schedule, tolerance requirement and whether exact size or nearest stock size is acceptable.
Pipe Type and End Finish
Confirm seamless, ERW, LSAW, SSAW, square tube, rectangular tube, plain end, beveled end, threaded end or coupling requirement.
Surface and Packing
Confirm black surface, oiled, painted, anti-rust coating, galvanized route, bundle packing, end caps, labels and shipping marks.
Common Carbon Steel Pipe Standards and Purchasing Routes
Different pipe standards serve different applications. Before price comparison, confirm whether the buyer needs pipe for pressure service, mechanical use, structural tube, line pipe, piling or general construction.
| Standard / Route | Common Buyer Requirement | Typical Product Form | Quotation Check Point |
|---|---|---|---|
| ASTM A53 | General carbon steel pipe for mechanical, pressure and ordinary pipe applications depending on grade and type. | Seamless or welded pipe, black or coated route by requirement. | Confirm Grade A/B, type, size, end finish, coating, hydrostatic test and MTC requirement. |
| ASTM A106 | Seamless carbon steel pipe for high-temperature or pressure-related service. | Seamless pipe, commonly Grade B or project-specified grade. | Confirm temperature/pressure service, grade, schedule, test requirement and whether seamless pipe is mandatory. |
| API 5L | Line pipe for oil, gas, water or pipeline projects. | Seamless, ERW, LSAW or SSAW route depending on size, grade and project requirement. | Confirm PSL level, grade, pipe type, length, bevel, coating, marking and inspection requirement. |
| EN 10210 / EN 10219 | Structural hollow sections for steel structures and construction projects. | Round, square or rectangular hollow sections. | Confirm hot finished or cold formed route, grade, dimensions, tolerances and project document requirement. |
| ASTM A500 | Carbon steel structural tubing for construction and structural applications. | Round, square and rectangular structural tubing. | Confirm grade, tube shape, dimensions, wall thickness, length and fabrication requirement. |
| JIS / GB Pipe Route | Regional standard pipe or tube supply for construction, structural or general fluid projects. | Seamless pipe, welded pipe, square tube, rectangular tube or project-specific route. | Confirm whether buyer accepts JIS or GB documents, and do not substitute standards without approval. |
