In addition to the hot extrusion method, there are also cone-shaped drilling machines or three-roller drilling machines to manufacture capillary tubes, periodic pipe laminators or continuous laminators, three-roller pipe laminators for extension and sizing (reduction) Diameter machines The process produces 2507 stainless steel tubes. This latter process is generally not a factory specialized in the production of 2507 stainless steel pipes, but a factory that produces several seamless steel pipes. 2507 stainless steel tubes are only part of their products. These factories generally use general purpose drills. Compared to the two-roller cross-lamination drilling machine, the deformation stress state of the cone and three-roller drilling machine is beneficial for steel or alloy deformation which is difficult to deform and has high deformation resistance. At the same time, you can prevent and reduce defects in the inner and outer surface of the steel pipe during the drilling process. Today, the two-roller cross-laminate drilling machine is rarely used abroad to produce 2507 stainless steel tubes.
To economically produce high quality stainless steel pipes, in addition to the advanced technologies mentioned above in the hot extrusion (rolling) process, steel manufacturing, heat treatment, finishing (straightening, blasting, polishing), cold rolling and cold drawing. They are also used. (Lubrication, degreasing, headheading), detection of non-destructive defects, etc., developed and adopted many new technologies and new processes.
The development of the stainless steel industry at home and abroad has been advancing. New technologies and processes have brought increased strength, heat resistance and corrosion resistance to stainless steel. This also allows our national 2507 stainless steel pipe to be placed on the shoulders of giants Well, the application and development of our country's 2507 stainless steel pipe is also progressing rapidly and can also take a place globally.
