Shandong Liaocheng Polygram Pipe Manufacturing Co. provides you with non-standard steel pipe, steel pipe is non-standard relative to the Chinese national standard seamless steel pipe shaped in terms of national standard outside, in the production of seamless steel pipe in accordance with national regulatory requirements machining with thick-walled pipe, with diameter size, wall thickness, and should allow a certain degree of error, error referred to the national standard in the standard range. In practical use, often national standard specification has some limitations, which corresponds to the emergence of non-standard seamless steel pipe, steel pipe non-standard specifications to supplement the national standard specifications and the production of seamless steel tubes, not said worse than the national standard seamless steel quality. In the non-standard steel pipe production, some with national standard seamless steel tube or round as production, because of the small sales volume, prices tend to be higher than the normal national standard seamless steel pipe, but there are drawbacks non-standard seamless steel pipe, because there is no fixed standard requirements, some manufacturers use two seamless steel scrap or defective as seamless tube, so the price is cheaper. So often non-standard seamless steel pipe 20 # thick-walled steel price volatility, product quality is uneven. Non-standard steel pipe commonly used materials are: 20 #, 45 #, 16Mn (Q345A, B, C, D, E) 27siMn, 20cr, 40cr and other Liaocheng Polygram steel plant is in production, research, import and export trade and one of the large enterprises, the main high-pressure boilers, boiler tubes threaded, seamless steel pipe, seamless pipe, small diameter seamless steel pipe, steel pipe, seamless steel pipe.
