Product Advantage
1. High Strength & Durability
Steel pipes are extremely strong and can withstand high pressure, heavy loads, and harsh environmental conditions.
They are resistant to impact, making them ideal for underground and high-stress applications.
2. Long Lifespan
Steel pipes have a long service life due to their corrosion resistance (especially when galvanized or coated).
They are less prone to cracking, bending, or warping compared to plastic or concrete pipes
Inspection
Common Steel Pipe Defects to Inspect For
Surface defects: Cracks, pits, scratches, laminations
Dimensional issues: Wall thickness variations, ovality, diameter deviations
Weld defects: Porosity, lack of fusion, cracks, undercuts
Corrosion & erosion: Internal/external rust, pitting, wall thinning
Material flaws: Inclusions, segregation, hydrogen-induced cracking
Packing &Shipping
Common Steel Pipe Packaging Methods
Bundle Packaging (Strapping)
Method: Pipes are grouped in bundles (usually 2–5 tons) and secured with steel straps or wires.
Best For: Small to medium-diameter pipes (e.g., seamless, ERW pipes).
Protection: Ends may be capped to prevent damage.
