ERW pipe
ERW pipe from Dongying Zhongke Petroleum Equipment Co., Ltd is produced using electric resistance welding technology to deliver consistent seam integrity and dimensional precision. The product is available in outer diameters from 25.4 mm to 168.3 mm, with wall thicknesses ranging from 2.0 mm to 8.0 mm. Material is typically ASTM A53 Grade B or SAE 1020 carbon steel, with minimum tensile strength of 415 MPa and elongation of at least 20%.
The manufacturing process involves cold-rolled strip forming followed by high-frequency induction welding, resulting in a narrow, uniform seam. Surface finish is mill finish, with no coating applied unless requested. In the oil and gas sector, this pipe is commonly used for casing, conduit, and low-pressure gathering lines where cost-effective, reliable performance is needed. The weld zone is typically free of internal flash, reducing flow restriction.
Buyers in oilfield services, infrastructure, and mechanical fabrication source this pipe for casing, scaffolding, and fluid conveyance systems. Packaging is in wooden crates or steel-bound bundles, shipped via container from Qingdao or Tianjin ports. Trade terms include FOB and CIF, with standard lead times of 25 to 35 days. Minimum order quantities are flexible and confirmed upon inquiry.

Sourcing ERW pipe from Dongying Zhongke Petroleum Equipment Co., Ltd - China Import Guide
Before ordering ERW pipe from this supplier, confirm the exact material grade, wall thickness tolerance, and weld inspection protocol. Request a mill test report with chemical analysis and mechanical test results. Do not assume compliance with API or ISO standards unless explicitly stated in writing for each shipment.
Logistics are handled from ports in Shandong or nearby, with lead times typically 25 to 35 days after deposit. Payment terms are commonly 30% advance, 70% against copy of bill of lading. Incoterms offered include FOB and CIF; buyers should clarify who arranges insurance and customs clearance. Packaging is in wooden crates or steel-bound bundles, suitable for sea freight.
Quality verification should include caliper measurements of diameter and wall thickness, visual inspection of the weld seam for cracks or porosity, and a bend test on a sample piece. Retain a representative sample for independent lab testing. Ensure the supplier provides batch traceability and a signed declaration of conformity. Avoid accepting pipe without documented test results for pressure or structural use.
