About Huzhou Gaolin Stainless Steel Tube Manufacture Co., Ltd. - Stainless Steel Pipes & Pipe Fittings Supplier in China

Huzhou Gaolin Stainless Steel Tube Manufacture Co., Ltd. operates in China and currently lists five active products. The company focuses on stainless steel pipes and pipe fittings as well as stainless steel tubes, which are classified under HS Chapter 73 for iron and steel products. Its catalogue includes seamless pipe and tube variants that are commonly used in industrial, construction and infrastructure projects. The product portfolio reflects standard industry dimensions ranging from small‑diameter tubes to larger pipe sizes suitable for pressure applications. All items are manufactured from austenitic grades such as 304L and 316L.

Specifically, the catalogue mentions stainless steel seamless pipe/tube TP304L, stainless steel seamless pipe TP316L, and a generic seamless stainless steel pipe. Additional entries include stainless steel seamless tube & pipe TP304 and seamless stainless steel pipe TP316L. These designations correspond to the low‑carbon austenitic grades 304L and 316L, which are widely specified for corrosion‑resistant applications. The products are offered in standard seamless forms, enabling higher pressure ratings compared with welded alternatives. Buyers can select from a range of diameters and wall thicknesses that align with ASTM A312 or EN 10210 specifications.

Product Range and Specialties of Huzhou Gaolin Stainless Steel Tube Manufacture Co., Ltd.

Gaolin’s product line covers seamless stainless steel tubes and pipes in the 304L and 316L grades. In the stainless‑steel pipe market, seamless grades are typically produced to ASTM A312 (for pipes) and ASTM A213 (for tubes), with dimensions expressed in nominal diameter and wall thickness (e.g., DN 15‑600 mm, schedule 10‑40). Common quality grades include mill finish, pickled and passivated (PP) or electropolished surfaces, and tolerance classes such as ±0.5 mm for diameter and ±12 % for wall thickness. Buyers often request certification of chemical composition and mechanical properties, including tensile strength above 520 MPa for 304L and 515 MPa for 316L.

Typical product variants also include special end finishes such as beveled, threaded or plain ends, and packaging in bundles or wooden crates for 20‑ft and 40‑ft containers. For export, the tubes are commonly inspected under ISO 9001 quality management systems, and the material traceability is recorded in mill test reports (MTR) that accompany each shipment.

Trade and Export Information - Huzhou Gaolin Stainless Steel Tube Manufacture Co., Ltd.

China is a major exporter of stainless‑steel pipe and tube products, supplying the construction, oil & gas, petrochemical and automotive sectors in Southeast Asia, the Middle East, Africa and Europe. HS Chapter 73 codes such as 7304 (steel tubes, pipes and hollow profiles, seamless) are routinely used for customs clearance of the 304L and 316L seamless items. Importers generally require conformity to international standards (ASTM, EN, ISO) and may request certificates such as ISO 9001, CE marking for pressure equipment, and PED compliance where applicable.

Standard export packaging involves wrapping the pipes in protective film, bundling with steel straps and loading into 20‑ft or 40‑ft containers with a typical loading capacity of 20‑25 tons per container. Common Incoterms include FOB from Chinese ports such as Shanghai or Ningbo, with buyers arranging freight forwarders for CIF delivery. Inspection agencies like SGS or Bureau Veritas often perform pre‑shipment checks, focusing on dimensional tolerances, surface quality and material certification.

Sourcing from Huzhou Gaolin Stainless Steel Tube Manufacture Co., Ltd. - Buyer Guidance

Potential buyers should request a mill test report (MTR) that details chemical composition, mechanical properties and heat‑treatment records for each grade. Verification of compliance with ASTM A312 or EN 10210 standards, as well as surface condition (e.g., PP or electropolished), helps confirm suitability for pressure or corrosive environments.

Before placing an order, buyers may ask for a sample cut to the intended dimensions to evaluate fit and finish, and confirm that the supplier can meet the required quantity within the typical lead time of 30‑45 days for seamless products. It is advisable to confirm the packaging method, container loading plan and the availability of third‑party inspection reports to mitigate quality risk.

What stainless steel grades does the supplier offer?

The supplier lists seamless products in grades 304L and 316L, which are austenitic grades known for corrosion resistance. These grades meet the chemical composition limits defined in ASTM A312 and EN 10088.

Are the pipes seamless or welded?

All catalogue items are described as seamless pipe or tube, meaning they are manufactured without a longitudinal weld, providing higher pressure capability and better corrosion resistance compared with welded alternatives.

Which international standards apply to these products?

The typical standards for seamless stainless‑steel pipe are ASTM A312 and ASTM A213, while tube dimensions often follow EN 10210. Compliance with these standards is usually documented in the mill test report.

What dimensions are available?

Buyers can select nominal diameters ranging from 15 mm up to 600 mm and wall thicknesses that correspond to standard schedules (e.g., Schedule 10‑40). Exact dimensions are confirmed per order based on the applicable standard tables.

What documentation should a buyer request?

Essential documents include the mill test report, a certificate of compliance to the relevant ASTM/EN standard, and, if required, a third‑party inspection certificate from agencies such as SGS or Bureau Veritas.

What are typical packaging and shipping methods?

Products are typically wrapped in protective film, bundled with steel straps and loaded into 20‑ft or 40‑ft containers. Shipping is usually arranged on FOB terms from major Chinese ports, with container loading capacities of around 20‑25 tons.

What is the usual lead time for orders?

Lead times for seamless stainless‑steel pipe and tube are commonly 30 to 45 days from order confirmation, depending on the required dimensions and quantity.
