GB Standard Alloy Pipes
The GB Standard Alloy Pipes are seamless steel tubes manufactured to GB/T8162 and GB/T8163 specifications. They are produced from alloy steel of the carbon‑manganese 16Mn/20Mn grade, delivering the mechanical strength required for industrial pipelines. The pipes are supplied by Big Co., Ltd., a harbor‑tier supplier based in Beijing, China.
In the steel industry, typical GB‑compliant pipes are offered with outer diameters from 48 mm to 610 mm and wall‑thickness schedules ranging 3 mm to 25 mm, which match the dimensions commonly required for pressure‑retaining systems. Standard pressure ratings for such pipes are PN10 to PN25, and tensile strength usually falls between 400 MPa and 600 MPa, providing sufficient resilience for fluid conveyance and structural use. The alloy composition also gives typical corrosion resistance comparable to standard carbon‑manganese grades. These characteristics make the pipes suitable for both low‑ and high‑pressure applications across sectors.
Construction firms, oil‑and‑gas contractors, and machinery manufacturers frequently source these pipes for pipelines, structural frames, and equipment housings. Buyers should request the exact diameter, wall thickness, and pressure rating needed for their projects, as Big Co., Ltd. can supply custom lengths. Trade terms such as flexible MOQ, FOB or CIF shipping, and ISO certification are mentioned, but the final incoterm, lead time and payment conditions must be confirmed with the supplier before purchase.
| Material | Alloy Steel (Carbon‑Manganese 16Mn/20Mn grade) |
| Standard | GB/T8162, GB/T8163 |
| Design | Seamless construction |
| Typical outer diameter range | typical 48‑610 mm |
| Typical wall thickness | typical 3‑25 mm (schedule) |
| Typical pressure rating | typical PN10‑PN25 (10‑25 bar) |
| Typical tensile strength | typical 400‑600 MPa |
| Typical length | typical 6 m per pipe |
| Typical packaging | typical bundled on pallets with rust‑inhibitor coating |
| Typical weight per metre | typical 7.85 kg/m for a 114 mm Ø pipe (example) |
Big Co., Ltd. is registered in the Tongzhou District of Beijing, China, and is listed with a harbor verification tier on the platform. The supplier’s profile shows a response rate of 0 % and no recorded average response time, indicating that communication must be initiated proactively by the buyer.
The company lists GB Standard Alloy Pipes and GB Standard Alloy Round Bar among its product catalogue, emphasizing compliance with Chinese GB standards and international certifications such as ISO. Export options include FOB and CIF shipping, and the supplier notes the ability to adjust order quantities to meet project requirements.
GB Standard Alloy Pipes are seamless steel tubes manufactured to GB/T8162 and GB/T8163 specifications, widely used in structural engineering, fluid conveyance systems, and industrial pipeline applications. These alloy steel pipes offer excellent mechanical strength and pressure resistance, making them suitable for construction, oil and gas, and machinery manufacturing. As China-manufactured products, they are competitively priced for global import markets and meet international quality benchmarks for industrial use.

Sourcing GB Standard Alloy Pipes from Big Co., Ltd. - China Import Guide
Before placing an order, confirm that the pipe dimensions, wall‑thickness schedule and pressure rating match the project specifications, and request the GB standard test report to verify compliance. Verify the supplier’s harbor tier status and ask for recent factory audit documents to ensure production capability. Also check that any claimed ISO certification is current and covers the specific pipe grade.
Discuss the preferred incoterm - typically FOB Shanghai or CIF Shanghai - and obtain an estimated lead time based on the required size and quantity. Payment terms are usually negotiable, with a common practice of a 30 % advance T/T and the balance against shipping documents; however, the exact terms should be agreed in writing. Shipping containers are loaded according to standard pallet dimensions, and a freight forwarder can be engaged to handle customs clearance.
Arrange for a third‑party inspection before loading, focusing on dimensional tolerance, wall thickness, and surface condition as per GB/T8162. Request mill test certificates and a heat‑treatment report where applicable to document material properties. Upon arrival, perform a visual check for transport damage and retain all inspection reports for future reference.
