The company successfully trial-produced 42CrMo4 Φ30.7mm*11.25mm small diameter ultra-thick wall pipe
Good news came from the R&D department. The 42CrMo4 Φ30.7mm*11.25mm small-diameter ultra-thick wall pipe developed by the company was successfully trial-produced, and all indicators met the requirements of EN10305 & EN10297 double standards, and reached customer procurement technical conditions. In the next step, the company will carry out mass production.
This order was put forward by the Russian customer, and the technical conditions of the purchase were finally determined after repeated negotiations between the company's foreign trade department, technical department and foreign businessmen. This condition has almost harsh requirements on dimensional accuracy, ovality, uneven wall thickness, physical properties, internal organization, and surface finish. After receiving the task, the R&D department immediately organized technology, production, and quality inspections to conduct multiple rounds of communication and demonstration, and finally formulated the wear + rolling + drawing process route, formed process documents, and conducted trial production. During the trial production process, the person in charge of each unit came to the front line to track the process execution, record the process data, and finally the trial production was successful.
The successful trial production of this order indicates that the company has made a breakthrough in solving the defects such as delamination, internal squareness, and transverse cracking in the production process of small-diameter ultra-thick wall pipes, and it also indicates that the company has improved its precision manufacturing and surface finish control. A level has gained valuable experience for the company to produce such products in the future.
