Description

Big size rectangular steel tube factory China yuantaiderun(accept oem odm obm)
Big size rectangular steel tube factory Yuantai Derun Group
1.What's big size rectangular steel tube factory?
Firstly, for large size rectangular steel tube, Yuantai people think that the outer diameter of rectangular steel tube is above 400×400mm to be considered as large diameter rectangular steel tube. Secondly, for large size rectangular steel tube factory, there are not many factories that can do 400×400mm rectangular steel tube, and there is only one factory in China that can do 800×1200mm OD rectangular steel tube like Yuantai Derun.

5.How is a large diameter rectangular steel tube produced?
Here is an example of how we produce a large diameter square steel pipe of 500 x 500 mm, which we will briefly introduce to you in a video. Of course, for larger diameters and more demanding applications, we need to use our tube re-drawing and forming process. You can contact our account manager to make an appointment to watch the production of a large diameter rectangular steel tube on site. Contact us Now.

    10.Mechanical properties of large diameter rectangular steel tubes
    The mechanical properties of large-diameter steel pipes are important indicators to ensure their ultimate performance (mechanical properties), which depend on the chemical composition and heat treatment system of the pipes. So based on different usage requirements, the mechanical properties of large diameter spiral steel pipes are specifically introduced from the aspects of tensile strength, yield point, and elongation.
    1. Tensile strength
    The maximum force (Fb) that the specimen bears during the tensile process at break, obtained from the original cross-sectional area (So) of the specimen（ σ）， Called tensile strength（ σ b) , in N/mm2 (MPa). It represents the maximum resistance of metal materials to failure under tensile force.
    2. yield point
    The stress at which a metal material with yield phenomenon can continue to elongate without increasing (maintaining a constant) force during the tensile process is called the yield point. If the force decreases, the upper and lower yield points should be distinguished. The unit of yield point is N/mm2 (MPa).
    3. Elongation after fracture
    In the Tensile testing, the percentage of the increased length of the gauge length and the original gauge length after the sample is pulled off is called the elongation. with σ Represented in%.
