Welded pipe introduction:

Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip steel after crimping and welding, and the length is generally 6 meters. Welded steel pipe has simple production process, high production efficiency, many varieties and specifications, and less equipment investment, but the general strength is lower than that of seamless steel pipe.

International standards and parameters
1
American standard square tube: ASTM A500 standard is implemented, with cold forming grading (Gr. A/B/C) for square tubes and an outer diameter tolerance of ± 0.5%

2
European standard square tube: meets EN 10219 cold formed square tube, with a wall thickness range of 1.0-16mm and a diagonal difference of ≤ 1.5mm

3
Japanese standard square tube: Welded square tube according to JIS G3466, commonly used sizes range from 50 × 50mm to 200 × 200mm

4
Australian standard square tube: AS/NZS 1163 square tube, tensile strength ≥ 450MPa, suitable for high corrosion environments

Application scenarios and advantages
1
Building structural square tube:
Efficient bolt connection with square tube right angled edges, saving 30% of steel structure construction time
Square pipes have better bending stiffness than round pipes, and when used as factory columns, the deflection is reduced by 40%
2
Mechanical frame square tube:
The internal space of the square tube facilitates the layout of cables/hydraulic pipes, improving equipment integration
Square tube surface can be milled/drilled, compatible with sensor and actuator installation
3
Transportation square tube:
The car collision beam adopts high-strength square tube (HSLA350 grade), which increases energy absorption by 50%
Fatigue testing of square tubes for rail vehicles (zero cracks after 1 million cycles)
4
Agricultural facility square tube:
Greenhouse square tube skeleton aluminum zinc anti-corrosion (≥ AZ150), with a lifespan of over 15 years
Square tube splicing type grain silo support column, with a wind pressure resistance level of 12
