The most important thing in the production of precision stainless steel pipes is welding, inner weld leveling and pickling process. The welding process in the production process is very technical. The welding seam must be smooth, and there must be no welding defects such as pores and slag, and the defects should be repaired in time; when the workpiece is required to be sealed and continuously welded, it is required that there should be no pores and trachoma at the weld. The internal leveling technology of the weld directly affects the anti-corrosion performance and quality of the inner wall of the pipe; and the time, temperature, and solution concentration in the pickling process need to be strictly controlled, otherwise inclusions will accumulate and cause corrosion of the pipe fittings, and the inclusions will fall off in the later period. Small pit-shaped defects are formed on the surface.


Technology will have a great impact on products, so production technology determines quality. According to the most basic standards, the precision of stainless steel precision tubes can basically reach ±0.05mm~±0.15mm. The tolerance range here is also a brief explanation. Generally, the tolerance range of pipes with relatively small diameter and thinner wall thickness is basically ±0.05mm. Relatively speaking, the tolerance range of stainless steel precision pipes with larger diameters is basically ±0.05mm~±0.15mm.
