Our stainless steel cylinders have achieved the world’s top-class clean performance with Rmax from 1 to 3s required for semiconductor production through precise inner surface polishing, and have been used by many major chemical manufacturers. For stainless steel welded cylinders, we conduct solid solution heat treatment to remove internal stress after performing advanced welding processing, and conduct x-ray inspection for all products to ensure the welding quality.
