Product Description
ASTM A554 304 Stainless Steel Welded Tubes
We are a professional manufacturer with over 25 years of experience producing ASTM A554 304 stainless steel welded tubes. Our pipes are widely used in gas hoses, water hoses, wire and cable protection circuits, and various industrial applications.
HS Code Classification
- 73064000: For pipes with outer diameter not exceeding 406mm
- 73062100: Stainless steel seam drilling for oil and natural gas applications (requires inspection and offers 13% tax refund)
Pressure Rating Specifications
Pressure capacity depends on two key factors: pipe formation (welded vs seamless) and wall thickness. Welded steel pipes typically withstand pressures up to 1.6 MPa (16 kg), while seamless pipes are suitable for higher pressure applications.

Pressure Calculation Formula
P = (2 × σ × δ) / (S × D)
Where:
P = Acceptable pressure
σ = Tensile strength
S = Safety factor
δ = Wall thickness
D = Outer diameter
Safety Factor Guidelines:
• P < 7MPa: S = 8
• P < 17.5MPa: S = 6
• P > 17.5MPa: S = 4
Where:
P = Acceptable pressure
σ = Tensile strength
S = Safety factor
δ = Wall thickness
D = Outer diameter
Safety Factor Guidelines:
• P < 7MPa: S = 8
• P < 17.5MPa: S = 6
• P > 17.5MPa: S = 4
