About GM Industrial Limited - Stainless Steel Pipes & Pipe Fittings Supplier in China

China hosts GM Industrial Limited, which currently lists six active products across its catalogue. The company’s top categories are Stainless Steel Pipes & Pipe Fittings, Electric Pumps and Industrial Couplings, and the product titles include Stainless Pipe Fittings, Ball Valve, Impeller Pump, Pipe Nipples, Camlock Quick Couplings and a generic CAMLOCK item.

The catalogue entries for Pipe Nipples and Camlock Quick Couplings both carry HS code 7307.23 and are specified as stainless steel grades 304, 316, 304L or 316L. Other items such as the Ball Valve and Impeller Pump are listed without explicit HS codes but fall under the same stainless‑steel pipe and pump families. All six products are presented as stainless‑steel components suitable for pressure‑bearing applications.

Product Range and Specialties of GM Industrial Limited

The stainless‑steel pipe fittings and couplings listed use grades 304, 316, 304L and 316L, which are the most common austenitic grades for corrosion‑resistant piping. In international trade these items typically comply with ASTM A403 (for forged fittings) or EN 1092‑1 (for welded fittings) and are offered in standard pressure classes such as PN10, PN16 and PN25. Ball valves in this segment are usually rated to API 6D or ISO 5217, with end‑connections matching the pipe size series. Impeller pumps are generally centrifugal designs, often supplied in stainless‑steel casings and impellers that meet ISO 9906 performance testing. Camlock quick couplings follow DIN 2822 or ISO 8434 dimensions, with standard 1/2

Trade and Export Information - GM Industrial Limited

China is a global exporter of stainless‑steel pipe components, and HS chapter 73 (iron and steel products) - specifically heading 7307.23 for stainless‑steel pipe fittings - is routinely inspected by customs under the EU’s REACH and the US’s CBP Automated Commercial Environment. Typical import destinations for these items include the United States, Germany, Saudi Arabia and South Korea, where the steel industry and oil‑&‑gas, food‑processing and pharmaceutical sectors demand corrosion‑resistant fittings.

Buyers commonly request ISO 9001 quality‑management certification, mill test reports (MTR) confirming the 304/316/304L/316L grades, and compliance documents such as CE marking for EU markets or PED certification for pressure equipment. Standard packaging involves wooden crates or steel pallets with internal cushioning to protect the fittings, and shipments are usually consolidated in 20‑ft or 40‑ft containers under FOB or CIF terms. Chinese exporters also follow the China Compulsory Certification (CCC) scheme for certain mechanical parts, although it is not mandatory for stainless‑steel pipe fittings unless specified by the buyer.

Sourcing from GM Industrial Limited - Buyer Guidance

When sourcing from GM Industrial Limited, request a full mill test report that verifies the chemical composition and mechanical properties of the stainless‑steel grade indicated for each product. Ask for dimensional drawings or CAD files to confirm connection sizes, pressure ratings and thread standards (e.g., NPT, BSPT) before confirming quantities.

Verify that any ball valve or impeller pump offered meets the relevant API or ISO performance standards and request a pressure‑test certificate at the intended service pressure. Confirm the HS code (7307.23) on the commercial invoice matches the product description to avoid customs delays, and ensure the supplier can provide the agreed packaging (e.g., 40‑ft container, wooden pallet) and the chosen Incoterm (FOB Shanghai or CIF destination).

What stainless‑steel grades are used for the pipe nipples and camlock quick couplings?

The catalogue specifies grades 304, 316, 304L and 316L for both pipe nipples and camlock quick couplings, which are the common austenitic grades for corrosion‑resistant fittings.

Which HS code applies to the stainless‑steel pipe fittings listed?

Both the Pipe Nipples and Camlock Quick Couplings are listed under HS code 7307.23, covering stainless‑steel tube and pipe fittings.

Are material test certificates available for the ball valve?

Material test certificates are not listed in the catalogue, so buyers should request a mill test report that confirms the stainless‑steel grade and mechanical properties before purchase.

What standard dimensions are typical for camlock quick couplings?

Camlock quick couplings usually follow DIN 2822 or ISO 8434 dimensions, with standard sizes such as ½", ¾" and 1" nominal bore.

What packaging is standard for shipping these stainless‑steel components?

Exporters typically use wooden crates or steel pallets with internal cushioning, and consolidate the goods in 20‑ft or 40‑ft containers for ocean freight.

Which certifications should a buyer request for these products?

Buyers should request ISO 9001 quality‑management certification, mill test reports for the stainless‑steel grades, and any market‑specific certifications such as CE marking for EU shipments or PED for pressure equipment.

What is the typical lead time for an order of stainless‑steel pipe fittings?

Lead times depend on production scheduling but generally range from 2 weeks to 6 weeks for standard stainless‑steel fittings once the order and required test reports are confirmed.

Can a sample be provided before a full order?

Suppliers of stainless‑steel pipe components usually provide a small sample unit for dimensional and material verification; buyers should request a sample and confirm the associated shipping terms.
