Machining requirements for precision stainless steel pipe fittings

Hangao Tech (SEKO) precision stainless steel welded pipe making machine (tube mill ) is equipped with uncoiler, Stocker ,The shear welder ,forming &welding machine, weld bead rolling machine, weld bead grinding machine, first sizing machine, cleaning, bright annealing machine, sizing and straightening machine, Eddy current testing, printing, pipe cutting machine, unloading machine.

  

Precision stainless steel pipe fittings are very distinctive in model specifications, appearance performance and so on. First of all, the thicker the wall of this stainless steel pipe fitting, the higher the cost performance and practicability. The thinner the wall, the higher the processing cost. In addition, the performance limits of stainless steel pipe fittings also depend on the machining process.

Usually stainless steel pipes have low accuracy, uneven wall thickness, and uneven tubing. Low brightness on the inside and outside surfaces and expensive length Settings. The inside and outside surfaces of the tube are prone to pitting and black spots, which are not easy to remove. In addition, the detection and shaping of thick-walled tubes of precision stainless steel pipe fittings must be handled off-line. Therefore, stainless steel pipe fittings show sufficient advantages in the field of high pressure, high strength mechanical structural materials.

According to the rolling process, stainless steel pipe fittings are mainly hot rolled, hot pressed and cold drawn (rolled) stainless steel pipe. According to the different metallography of stainless steel, it mainly includes half ferritic half Markov stainless steel pipe, martensitic aging stainless steel pipe, austenitic system stainless steel pipe, austenitic iron system stainless steel pipe, etc.

 

 

Defects such as cracks, folds, cracks, rolling, delamination and scarring are not allowed on the internal and external surfaces of precision stainless steel pipe fittings. This type of defect needs to be completely eliminated (unless specifically used for machining) and the wall thickness should not exceed the negative deviation of the outside diameter after removing the wall of the stainless steel pipe fitting. Some minor surface defect cannot be eliminated as long as it does not exceed the allowable negative deviation.
