ASTM ERW Welded Steel Pipes

Brand ZCXH
Product origin Shandong,China
Delivery time 10-20 days
Supply capacity 1000 tons/ month

ASTM ERW Welded Steel Pipes stand out for reliability and efficiency. Manufactured via Electric Resistance Welding (ERW), they feature strong, uniform welds, ensuring consistent pressure resistance—ideal for water, gas, and oil pipelines. Compliant with ASTM standards, they guarantee quality and dimensional accuracy, simplifying installation. Made from high-grade steel, they balance durability and cost-effectiveness, withstanding corrosion in diverse environments. Lightweight yet robust, they suit both industrial and municipal projects. Their seamless-like performance and mass-production capability make them a versatile, economical choice for large-scale applications.

Product Description

ASTM ERW (Electric Resistance Welding) Welded Steel Pipes are manufactured by rolling hot-rolled steel strips into a tubular shape via the ERW process, then fusing the pipe edges using resistive heat generated by electric current. Their core features center on "ASTM standard compliance, process advantages, and performance adaptability," detailed as follows:

Strict Adherence to ASTM Standards, Stable and Controllable Quality

Standardized Production & Performance Assurance
Fully compliant with ASTM series standards (e.g., ASTM A53/A53M, ASTM A106, ASTM A333—each standard corresponds to specific applications), which clearly regulate the pipes’ chemical composition, mechanical properties, dimensional tolerances, and weld quality:

Material: Mostly made of low-carbon steel (e.g., A53 Grade A/B) or low-alloy high-strength steel with a carbon content ≤ 0.3%, ensuring excellent weldability and toughness.
Mechanical Properties: Tensile strength ranges from ≥310MPa (A53 Grade A) to ≥415MPa (A53 Grade B), yield strength ≥180MPa, and elongation ≥20%, meeting diverse pressure and structural requirements.
Quality Inspection: Mandatory tests include hydrostatic testing (to verify pressure tightness), eddy current testing (to detect surface weld defects), and ultrasonic testing (to inspect internal weld quality). Some standards also require bending tests and impact tests to eliminate non-conforming products from entering the market.

High Dimensional Precision & Strong Compatibility
The pipe diameter ranges from DN15 (outer diameter 21.3mm) to DN600 (outer diameter 610mm), with wall thickness tolerance controlled within ±10% (far better than ordinary welded pipes). Additionally, the outer diameter roundness and straightness (error ≤ 1mm/m after straightening) are strictly controlled. This high precision allows direct matching with standard fittings (e.g., flanges, elbows, tees) without secondary processing, reducing assembly errors and leakage risks in pipeline systems.
