Coal slurry and slurry pipeline need to use straight welded pipe, and the pipeline transportation is "pasty". Pipeline transportation is the upward direction. Because the weld excess height of spiral welded pipe is spiral, which has great resistance to coal slurry, and the pipe needs a large wall thickness, it is inclined to adopt straight welded pipe.
Machinery, construction, chemical industry and other industries need straight welded pipes. At present, the inner hole of valve seat is machined after forging in mechanical industry, which is labor-consuming, time-consuming and material-consuming. If thick-walled straight seam welded pipe is used, it will be much more economical. In addition, due to the requirements of mechanical properties of anti-flattening, only straight welded pipes are used for building pipes; Straight welded pipe is also expected to be used for chemical pipes.
The company's products are mainly used for high-,medium-and low-pressure fluid transmission pipelines and structural steel pipes such as oil, natural gas, water, steam, gas, etc., and have undertaken landmark projects at home and abroad. The products are sold to various cities and exported to more than 80 regions such as Southeast Asia, Middle East, Europe and America, and enjoy a high reputation in China.
