Buy & Import JIS Seamless Pipes & BS Seamless Pipes from Big Co., Ltd. - China Wholesale Supply

JIS Seamless Pipes & BS Seamless Pipes from Big Co., Ltd. are cold-drawn and hot-rolled carbon steel tubes conforming to Japanese Industrial Standards and British Standards, respectively. The JIS range includes Grade STPG 370 and 410, while the BS range covers Grade 360 and 410, both designed for high-pressure and structural applications. Sizes span hot-rolled outer diameters from 51 to 508 mm with wall thicknesses of 7 to 60 mm and lengths up to 16,000 mm, cold-drawn outer diameters from 10 to 50 mm with wall thicknesses of 2 to 10 mm, and hot-expanded outer diameters from 325 to 1,020 mm with wall thicknesses of 6 to 50 mm.

The pipes are manufactured from solid carbon steel billets, bored, heated, and drawn to form seamless tubes with a typical tensile strength of 75,000 psi. Standard surface treatments include oil-dip, varnish, passivation, phosphating, shot blasting, and epoxy or FBE coating, with beveled ends, black painting, plastic caps, or wooden protection for packaging. These tubes undergo rigorous testing, including chemical composition inspection, mechanical properties tests (tensile, yield, elongation, flaring, flattening, bending, hardness, and impact), dimensional checks, non-destructive testing, and hydrostatic testing to ensure compliance with industrial standards.

These seamless pipes are used in oil and gas transmission, petrochemical plants, boiler systems, automotive exhaust systems, and machinery components such as shafts and bearings. Buyers typically source them in bulk for infrastructure projects, with packaging tailored for seaworthy export. The tubes are suitable for applications requiring high strength, pressure resistance, and corrosion durability, making them a preferred choice for industries like metallurgy, shipbuilding, and medical equipment manufacturing.

Frequently Asked Questions About JIS Seamless Pipes & BS Seamless Pipes from Big Co., Ltd.

Sourcing JIS Seamless Pipes & BS Seamless Pipes from Big Co., Ltd. - China Import Guide

Before ordering JIS or BS seamless pipes from Big Co., Ltd., verify the exact grades (STPG 370/410 for JIS, 360/410 for BS) and confirm the manufacturing process (cold-drawn, hot-rolled, or hot-expanded) matches your project requirements. Check whether the supplier can provide mill test certificates and third-party inspection reports for chemical composition and mechanical properties, as these are critical for compliance with industry standards.

Logistics details to confirm include the maximum length per pipe (up to 16,000 mm for hot-rolled, 12,000 mm for hot-expanded), packaging type (beveled ends, black painting, wooden protection), and whether the supplier can accommodate custom lengths or surface treatments. Clarify Incoterms such as FOB or CIF, port of loading in China, and lead times, as these are not specified in the listing.

For quality checks, insist on hydrostatic testing and non-destructive testing reports to ensure the pipes meet pressure resistance requirements. Request documentation for surface treatment methods (e.g., epoxy coating, passivation) and verify that the pipes are bundled and protected for seaworthy export. Confirm whether the supplier provides additional certifications, such as ISO or PED, which are typical for industrial-grade seamless pipes.
