Material
These pipes are manufactured from carbon steel conforming to the ASME SA139 (ASTM A139) specification for electric-fusion (arc) welded spiral‑ or straight‑seam pipe. They are designed for conveying liquids, gases, or steam and are suited to high‑strength structural and pressure‑resistance requirements (cited per ASTM A139/A139M).
Specifications
• Nominal Pipe Size (NPS): 4″–92″ (typical automotive use: 4″–36″)
• Wall Thickness: up to 1.0 inch (25.4 mm) typical
• Form: Spiral‑welded (SAW/SSAW) pipe, saw‑cut ends, plain/beveled/treaded finish

Mechanical Properties
| Grade | Min Yield Strength (psi / MPa) | Min Tensile Strength (psi / MPa) |
|---|---|---|
| A | 30,000 psi (~205 MPa) | 48,000 psi (~330 MPa) |
| B | 35,000 psi (~240 MPa) | 60,000 psi (~415 MPa) |
| C | 40,000 psi (~290 MPa) | 70,000 psi (~485 MPa) |
| D | 42,000 psi (~290 MPa) | 60,000 psi (~415 MPa) |
| E | 52,000 psi (~360 MPa) | 66,000 psi (~455 MPa) |
Major Characteristics
– High strength and toughness for pressure resistance.
– Fabrication flexibility: spiral welding enables large diameter and long lengths.
– Consistent quality through standardized electric‑fusion weld process.
– Economical production compared to seamless or LSAW alternatives.
– Suitable for straight or saw‑cut end finishes for custom assembly.
Applicable Standards
ASTM A139 / ASME SA139 provides grade definitions, chemical and mechanical requirements, and testing protocols.
Applications in the Automotive Industry
– Structural frames or supports: large‑diameter tubular supports or lift shafts.
– Fluid transport systems: low‑pressure oil or coolant delivery under vehicle assembly.
– Hydraulic or pneumatic conduit: robust piping for material handling or robotics within plants.
– Engineering equipment: machinery and structural piping in automotive manufacturing facilities.
