Precision antimicrobial stainless steel welded pipe is a type of straight seam welded pipe with a more precise surface or size. This is an antimicrobial
stainless steel pipe that is formed by extruding a steel strip through a die and then welded automatically or manually. This tube is simple to set the size, high production efficiency, variety of specifications, used in machinery, furniture, sanitary ware, electrical appliances and engineering components are more common, different applications for precision requirements are also different.
First of all, welded pipe than seamless pipe in the production method is more advantageous; welded formed steel pipe wall thickness is more uniform, but also arbitrary sizing, whether the diameter or wall thickness size can be accurately controlled; welded pipe can be made thick-walled or thin-walled, can control the raw materials at will, which is also the audience of antibacterial stainless steel welded pipe is more widely important reason, the following look at the precision are reflected in what places it.
First, the surface smoothness: like furniture, bathroom with antibacterial
Stainless Steel Precision Tube on the surface smoothness requirements are very high, using mechanical polishing or electrochemical polishing method, surface scratches, rust and sand eyes outside, high precision need to reach 6K mirror effect, the finish Ra value is about 0.8μm, and can not be polished excessively resulting in uneven wall thickness. Weld residual height is more difficult to deal with, in addition to testing polishing technology, welding forming between the steel strip and steel strip overlap precision directly affects the weld residual height, precision antibacterial stainless steel welded pipe in the welding forming process using high-end equipment, coupled with the late precision polishing, the weld almost zero touch.
Second, verticality: electronic and electrical enclosures have certain requirements for the verticality of the welded pipe, through the computer according to the pipe bending situation detection data after measurement and control system processing to give straightening correction control parameters, and then PLC control servo speed motor drive rotary top, so that the workpiece of the larger bending point direction vertical up, and then the hydraulic cylinder to perform linear action to drive the pressure head down the workpiece, to complete the straightening cycle. In addition to the straightening process, the cutting process will also have an impact on the verticality, when the stainless steel workpiece hardness is low, wall thickness is small, the cutting process is easy to make the tube body bending, tilting; we Jiangpu special steel will choose the right hardness of the material, and the use of laser cutting process, the operation of the workpiece zero contact to ensure the verticality of the
Precision Stainless Steel Tube.
Third, the ellipticity: some of the special components of machinery and equipment need to be punched, drilled or slotted in the body of the tube, this process is easy to cause the body of the tube depression, tube mouth deformation. Laser process can avoid the impact on the mouth of the tube deformation, and punching process, the mold through precision customization, no matter the shape or size are not worn, to ensure that the antibacterial
stainless steel tube and mold high degree of conformity, to ensure that the ellipticity is controlled at a very low value.
