EN 10210-1: Hot Finished Seamless Structural Hollow Sections of Non-Alloy Steels
Yizeng can offer different grades of steel pipes, such as S235JRH, S275JOH, S275J2H, S355JOH, S355J2H, S355K2H, etc.
EN 10210-1 hot-finished hollow section tube is made from non-alloy structure steel and fine-grain structure steel. It features simple form, excellent strength properties, durable, compact structure and wide specifications and dimensions. Adopting appropriate types of steels can optimize function and affordability of this hollow section pipe. This hollow section tube is broadly made use of in the frame structure of buildings, bridge structure, railing, mechanical frame structure, frame structure of transport vehicle, scaffolding, rack or spline and pinion elevator, crane, etc.
According to the requirements of customers and standards, we do horizontal and longitudinal defects online testing for the in and out of hollow section tubes. Therefore, we’re able to supply qualified and excellence seamless steel water pipes.
We also own professional pphysical and chemical testing center and international level advanced testing equipment for hollow section pipes, for German full spectrum direct-reading spectrometer, Japan metallurgical microscope, impact testing machine, tensile testing machine, computer controlled electro-hydraulic servo universal testing machine and a number of machine tools. They can do drawing, flaring, flattening, curling and also other physical tests for non-alloy structural steels and fine grained structural steel hollow section tubes and thereby ensure stable performance of steel.
Yizeng also configures Siemens electronic controlled six roller straightening machine that can straighten hollow section pipes after being chilled and ensure the pipe straightness complying with the requirements of customers and standards.
