ERW Steel Pipes from Permanent Steel Manufacturing Co., Ltd. are produced using electric resistance welding for structural and low-pressure fluid applications. The pipes are available in outer diameters from 21.3mm to 114.3mm, manufactured from carbon steel grades Q195 to Q345, and conform to ASTM A53 and BS EN standards. These dimensions and materials suit construction, scaffolding, and water distribution systems.
The material grades Q195 to Q345 indicate yield strengths from 195 MPa to 345 MPa, with carbon content controlled for weldability. Wall thicknesses are typically 1.8mm to 6.0mm, aligned with standard schedules for small-diameter piping. Pipes are supplied with plain ends, mill scale finish, and bundled in 1 to 2 metric ton units. Surface quality is consistent with industrial-grade applications, though no coating or anti-corrosion treatment is applied unless specified.
These pipes are commonly sourced by construction firms in Southeast Asia, Africa, and Latin America for scaffolding, irrigation, and low-pressure gas lines. Buyers typically order in container quantities, with MOQs starting at 5 to 10 metric tons. Packaging is steel-strapped bundles for container loading. Lead time averages 20 to 30 days after order confirmation. Incoterms are usually FOB Shanghai or Ningbo.

Before ordering, confirm the exact material grade (Q195, Q235, Q345) and its corresponding mechanical properties. Request mill test reports for each batch showing carbon, manganese, yield, and tensile strength. Verify that the outer diameter and wall thickness match the specified tolerance. Do not accept generic certifications without batch-specific data.
Confirm Incoterms, loading port, and destination port. FOB Shanghai or Ningbo is typical. Lead time is approximately 20 to 30 days after deposit. Payment terms are usually 30% advance, 70% against BL copy. Request a production schedule and container loading plan. Clarify whether packaging is steel-strapped or palletized.
Conduct pre-shipment inspection for dimensional accuracy, seam integrity, and marking legibility. Use calipers to verify diameter and wall thickness. Check for surface defects such as seams, laps, or cracks. Ensure each bundle is labeled with grade and size. Retain samples for independent lab testing upon arrival, especially for chemical composition and elongation.
