Runhai supplies seamless API pipe made from carbon steel API 5L Grade B, a material recognised for its strength and corrosion resistance in downstream oil, gas and water transmission. The product is offered in nominal diameters from 0.5 inch to 30 inch, covering a broad spectrum of pipeline sizes. Wall thickness is available in standard Schedule 40 and Schedule 80 dimensions, providing flexibility for different pressure requirements. All dimensions conform to API 5L and ASTM A53 specifications, ensuring compatibility with international pipeline codes.
In the pipe industry, API 5L Grade B carbon steel is a common choice for medium‑pressure lines, typically tolerating a pressure of up to 1 500 psi at 100 °F. Standard dimensional tolerances are ±0.5 % of the nominal diameter, while wall‑thickness tolerances follow the ±0.125 inch rule for Schedule 40 and ±0.250 inch for Schedule 80. End finishes are generally plain, allowing field welding or threading as required. For corrosive environments, buyers may request external coating, although the listed product is supplied uncoated as a typical baseline.

Before placing an order with Runhai, importers should request the latest mill test report, API 5L certification and a chemical analysis of the carbon‑steel grade. Verifying the supplier’s quality system, such as any ISO certifications, helps ensure the pipe meets the required mechanical properties. It is also advisable to confirm the exact diameter, schedule and end‑finish specifications to avoid mismatches during project engineering. Documentation of these details should be obtained in advance of contract signing.
Logistics for Chinese pipe exports commonly use FOB Shanghai, Ningbo or Qingdao, but the final incoterm must be agreed with Runhai on a case‑by‑case basis. Typical lead times for seamless API pipe range from four to six weeks after order confirmation, subject to production scheduling and shipping slot availability. Payment methods are usually irrevocable L/C at sight or telegraphic transfer, and buyers should align payment milestones with production stages. Any special freight requirements, such as containerised loading or bulk vessel charter, need to be discussed early.
Quality assurance can be reinforced by arranging a third‑party inspection at the factory, focusing on dimensional checks, wall‑thickness measurement and hydrostatic pressure testing. Buyers may also request ultrasonic testing reports to detect internal defects. Upon shipment, the supplier should provide a certificate of conformity, mill test report and a packing list, which are essential for customs clearance and downstream verification. Maintaining clear records of these documents streamlines the import process and reduces the risk of non‑compliance.
