Under normal circumstances, small holes will appear on its surface. These small holes are mainly caused by the hot rolling of the material during the processing. The high surface temperature of the pa

(1) The raw materials are strip coils, welding wires, and flux. Strict physical and chemical tests are required before investment. (2) Butt joint of strip steel head and tail, using single-wire or do

There are reasons for mechanical leakage. For example, the reliability of the hydraulic system depends to a large extent on the design of the hydraulic system seal and the selection of seals. Due to t

The quenching and tempering treatment of the honing tube refers to the high temperature tempering of the tube after quenching. The purpose is simple, which is to make the quenched and tempered honing

The honing pipe is different from ordinary pipes, so no matter its processing method or pipeline layout, it has very special requirements. A detailed description is made around these two aspects, so t

The job of honing the tube is actually simple to reduce the surface roughness of the workpiece, but many people don't know how the honing tube works, let's briefly understand how the honing tube works

The basic feature of St52 Honed Tube production is that the pipe material before cold deformation and after the accumulated cold deformation has reached a certain level, a series of preparations are r

The global economic crisis has deeply affected every industry, of course, the production industry should be the most affected. At that time, production companies in many places all closed down, and in

The first stage is the shedding cutting stage. In this constant-pressure honing, due to the rough hole wall at the beginning, the contact area between the whetstone and the hole wall is small, the con

​Long Jin editor today shares with you: honing pipes are mainly used in engineering, metallurgy, plastics, mining, road construction, textiles and other industries. There are three main types of honin

The Hydraulic Honed Tube unit is a complete set of equipment for producing pipes by cold rolling, cold drawing, or a combination of cold rolling and cold drawing. It is a unit for deep processing of h

Rolling processing plays an active role in forming the honing tube. The honing tube is different from ordinary steel pipe materials. It is a high-precision product. The outer wall has no oxide layer,
