Threeway Steel Co., Ltd. manufactures spiral welded pipes from carbon steel grades Q235, Q345 and API 5L Grade B‑X80. The pipes are fabricated by spiral submerged arc welding of hot‑rolled coils or narrower plates, a process that reduces material waste. They are certified to API 5L, ASTM A252 and GB/T 9711 standards, covering oil‑and‑gas and water pipeline requirements. Typical product dimensions include diameters from 300 mm to 3 200 mm and wall thicknesses between 8 mm and 22 mm, although exact sizes must be confirmed with the supplier.
Coating options are not listed, but the manufacturing approach commonly supports internal epoxy and external polyethylene systems for corrosion protection. The large‑diameter capability makes the pipes suitable for long‑distance water transmission, crude oil and natural gas transport, and deep‑foundation piling. Infrastructure developers and energy companies often select these pipes for projects that demand high pressure tolerance and cost efficiency. The supplier highlights that the spiral geometry allows lower production costs compared with longitudinal welding.
Trade terms such as MOQ, pricing and lead‑time are not disclosed in the listing and should be negotiated directly with Threeway Steel. Buyers typically arrange FOB or CIF shipments from the Hunan region, with payment terms ranging from T/T to L/C depending on order size. Confirmation of the exact grade, dimensions and any required coating must be obtained before finalising the contract.

When engaging Threeway Steel, first verify the exact steel grade, diameter, wall thickness and any coating specifications required for your project. Request the mill test report, coating certification and any relevant third‑party inspection documents to ensure compliance with API 5L, ASTM A252 and GB/T 9711. Confirm that the supplier can meet any project‑specific regulatory standards before signing a purchase agreement.
Logistics are usually arranged on an FOB basis from the Changsha port or as CIF to the buyer's destination port. Because lead‑time information is not published, ask the supplier for a production schedule and estimated shipping date. Payment terms are negotiable and may range from advance T/T to a letter of credit, depending on the order volume and buyer's credit history.
Implement quality assurance by scheduling independent inspections either at the factory before loading or upon arrival at the destination. Typical inspection points include dimensional checks, coating thickness measurement and hydrostatic pressure testing. Secure the full set of documentation - mill test report, coating data sheet and inspection certificate - to facilitate customs clearance and downstream project acceptance.
