Development of cold-rolled cold drawn tubes production process and modification procedures

According cold working methods used, the process can be divided into pull tab schedule (using cold drawing deformation) and rolling table (using cold deformation) as well as rolling and pull tabs (two cold-rolled cold drawn deformed) Since cold-rolled cold drawn pipe production features a multi-step and cyclical, and many varieties, in order to be able to produce a reasonable and orderly manner, the preparation process schedule is very important.

Welding principle of plastic deformation for seamless steel pipe

Seamless heat treatment after welding is a new technology to eliminate residual stress, this technology can improve the metal's resistance to stress corrosion, and heat treatment temperature is higher, the elimination of residual stress, the better, of course, the heat treatment or can effectively improve the corrosion resistance of welded steel pipe. Try to make the weld metal biphasic organization, content to make ferrite controlled more than three percent, five percent, while the need yo selection of quality basic coated electrodes, so that you can limit the welding seam metal three kinds of S, P, C and other content.

Straight Seam Steel Pipe Hot Deformation Processing Method

Heat treatment is an important process in the manufacture of machinery, as compared with other processing, heat treatment generally does not change the overall shape and chemical composition of the workpiece, but by changing the microstructure within the workpiece, or a change in the chemical composition of the workpiece surface give or improve the performance of the workpiece. Its characteristics are intrinsic to improve the quality of the work, which is generally not the naked eye can see.

40cr SMLS Pipe Composition and Role

40cr smls pipe production methods can be hot-rolled, hot extrusion, cold rolling and cold drawing. In recent years, due to the continuous casting and rolling technology and a variety of new welding technology and non-destructive testing technology applications, 40cr smls pipe quality continues to improve, in the use of all parts of the replacement of 40cr smls pipe, The price is about 20% lower than the seamless tube.

Production process flow and deformation procedures of cold drawn steel tube

To develop the production of pipe rolled drawing of the deformation process and procedures in the cold-drawing unit in the pipe, it must be put into operation before the product production process, deformation parameters and processing equipment selection and so there is a clearly defined, as the basis for the organization of production and operation, and this work is the preparation process schedule.

Straight Seam Steel Pipe Common Problems and Preventing Measures

Straight seam steel pipe is steel or steel after bending molding, and then made by welding. It is cut into strips by a steel strip, and then wrapped into a tubular cold mold. The special welder then welds a seam. Outer weld brightly polished. The inner pipe of the general burr does not hit.

Cold Sores - A Pandemic?

Cold sores are one of the most contagious viruses known to man and have been for over 2,000 years. The more you know about this enemy, the better you can deal with it. Although medical technology has not been able to find the answer to this dreaded virus, natural science offers some excellent solutions.
