Buy & Import Longitudinal Submerged-Arc Welded Steel Pipe from Botop Steel Pipe CO.,LTD - Wholesale Supply

The Longitudinal Submerged-Arc Welded (LSAW) Steel Pipe offered by Botop Steel Pipe CO.,LTD is a large‑diameter pipe produced by a two‑step submerged arc welding process. It is manufactured from carbon steel grades B, X42, X52, X60 and X65, providing a range of strength levels for different pressure requirements. The product meets API 5L, ASTM A53 and ISO 3183 standards, which are the benchmark specifications for oil‑and‑gas transmission and water conveyance pipelines. Typical applications include high‑pressure oil pipelines, municipal water mains and structural piling projects.

Industry practice supplies these pipes in diameters from 16 inches up to 80 inches, with wall thicknesses that typically range between 0.25 in and 1.5 in, allowing engineers to select the appropriate pressure class. Standard pressure ratings for API 5L grade X52, for example, reach up to 150 bar, while higher grades such as X60 and X65 support even greater pressures. External protection is often applied in the form of epoxy or coal‑tar coating, which are typical corrosion‑mitigation measures for pipelines exposed to aggressive environments. Standard shipped lengths are usually 12 m to 14 m, facilitating handling and welding on site.

Target buyers include oil‑field developers, water utility companies and construction firms that require reliable pipe solutions for long‑distance transport. Botop Steel Pipe CO.,LTD packages the pipes in bulk steel bundles secured on pallets, and it can arrange shipment under FOB or CIF terms depending on the buyer’s preference. The listing does not state a fixed minimum order quantity, allowing flexibility for projects of varying scale. Prospective importers should request the latest mill test reports and confirm compliance with the relevant API or ASTM standard before finalising a purchase.

Discuss logistics early, specifying whether you prefer FOB or CIF terms and asking the supplier to outline the expected lead‑time based on the order volume. Payment arrangements are usually conducted via L/C or T/T, but the precise conditions should be negotiated directly with Botop Steel.

Arrange a pre‑shipment inspection to verify material grade, dimensional tolerances and coating integrity. Request documentation that includes the mill test report, certificate of conformity and any relevant quality‑system certificates.
