The product is a JIS G3455 STS370 seamless carbon steel pipe designed for high‑pressure service. It conforms to the JIS G3455 execution standard and is supplied in diameters from 10.5 mm to 660.4 mm (6A to 650A / 1/8B to 26B). Manufacturing can be hot‑finished seamless or cold‑finished seamless, and the pipe is offered with flat ends, with beveled ends available on request. The grade STS370 provides reliable strength for temperatures up to 350 °C, and the length is customizable according to buyer specifications.
Carbon steel is the base material, offering a good balance of strength and ductility for industrial piping. Typical wall‑thickness tolerance for seamless pipe of this class is ±0.2 mm, and a standard pressure rating of up to 20 MPa is commonly applied to STS370 grade. Surface condition is a smooth mill finish, and optional coating can be arranged if corrosion resistance is required. Standard quality tests include hydrostatic pressure testing and tensile testing in line with JIS requirements.
The pipe is widely used in chemical plants, refineries, power generation facilities and other sectors that need durable tubing for high‑pressure conveyance. Importers source it for machine‑part assemblies and plant‑level piping networks. Buyers should confirm the required length, end treatment and any special packaging; typical trade terms include FOB or CIF, with payment and incoterms to be negotiated directly with the supplier.

Before placing an order, verify that the pipe grade, diameter, wall‑thickness tolerance and end type match the project specifications. Request the latest mill test report and a certificate of compliance with JIS G3455 to confirm material quality. Any special surface treatment or coating should be agreed in writing prior to production.
Logistics should be clarified early: discuss preferred incoterms such as FOB Cangzhou Port or CIF Shanghai, and confirm the expected lead time based on the customized length and any post‑processing. Packaging is typically in bundled bundles or pallets, but buyers may request protective wrapping for long shipments. Payment terms are negotiated directly with Botop Steel Pipe CO., Ltd and should be documented in the sales contract.
Arrange a third‑party inspection at the factory or prior to loading to verify dimensions, wall thickness and surface finish. Hydrostatic testing results and tensile test certificates are essential documents for quality assurance.
