Product Description
Square Tubing
1.Company Introduction
Jinan Xin Jiyuan Special Section Co.,LTD locates in Jinan where is the capital of Shan Dong province. Our company established in 1997. We have 16 years’ experience in producing square pipe and rectangular pipe. In order to expand our company, we invest RMB 16 million to build our new factory in 2011. Our production lines can manufacture all sizes of pipes according customers’ requirements.

2. Technical requirements:
1). Chemical Composition:
Yield Strength Grade | Demotic Raw-material Grade |
235 | Q235B, Q235C, Q235D, Q235qC, Q235qD |
345 | Q345A, Q345B,Q345C,Q345D,Q345Qc, Q345Qd, StE355, B480GNQR |
Carbon Equivalent
Ceq(%)=C+Mn/6+Si/24 +Ni/40+Cr/5+Mo/4+V/14
Ⅰgrade product Ceq(%)
Yield Strength Grade | 235 | 345 | 390 |
Ceq(%) | ≤0.36 | ≤0.43 | ≤0.45 |
Note: In order to improve the performance of steel,390 could add the microelement such as V, Nb, Ti, Mo and N etc. | |||
2). Mechanical Property:
Yield Strength Grade | W.T (mm) | Yield Strength (Mpa) | Tensile Strength (Mpa) | Elongation (%) | (20°C) Impact Value J |
235 | 4~12>12~22 | ≥235 | ≥375 | ≥23 | ≥27 |
345 | 4~12>12~22 | ≥345 | ≥470 | ≥21 | ≥27 |
390 | 4~12>12~22 | ≥390 | ≥490 | ≥19 | ≥27 |
3). ⅠGrade Product Yield Strength:
Yield Strength Grade | Outside perimeter (mm) | Wall Thickness (mm) | Yield Strength % | |
Directly to Square | Round to Square | |||
235 | ≥800 | 12~22 | ≤80 | ≤90 |
345 | ||||
390 | ≤85 | ≤90 | ||
Note: when the outer perimeter less than 800mm,can be determined by supply and buyer | ||||
3. Manufacturing Process:
1).Directly into Square: make continuous angle deformation of cold-rolled or hot-rolled steel plate directly, and then by high frequency welding form a rectangular steel tube forming method. Also known as square-square method.
2). Round to square: make continuous angle deformation of cold-rolled or hot-rolled steel plate directly, and then by high frequency welding form a round steel tube forming method, though the reshaping finally form a rectangular steel tube forming method. Also known as round to square method.
