Products Description
Structural Pipes are general-purpose seamless steel pipes for structural applications, complying with international standards such as ASTM A53, EN10210, and EN10216. They are widely used in construction, machinery manufacturing, rail transit, oil extraction, and chemical equipment.
Material & Production
Materials: St370, St440, St55, St520, CK45, P195GH, P235GH, P265GH, etc.
Production methods: Hot-rolled, cold-rolled, cold-drawn, etc.
Key difference from fluid pipes: No mandatory hydrostatic testing or non-destructive examination (NDE) per piece.
Specifications & Quality Control
OD range: 60–1420 mm
Wall thickness range: 0.5–30 mm
Defect control: Measures include improving steel cleanliness and optimizing crystallization quality to prevent laminar defects.
Application monitoring: In boilers, scale buildup exceeding 1 mm can cause abnormal pipe wall temperatures, requiring dynamic early-warning systems.
Applications & Services
Typical uses: Metro steel supports, nuclear power equipment, etc.
Deep processing: Supports welding, stamping, and other customized production services.
