Description

Threaded couplings refer to pipe connections with threads, which are the most common type of pipe fittings in industry and life.
The meaning of threaded coupling is: threaded joints make the connection of the pipeline easier, and it is easier to disassemble and replace, which greatly saves the cost of pipeline connection.

 

Surface natural whitening treatment
In the process of processing, stainless steel undergoes coiling, binding, welding, or artificial surface fire-roasting and heating treatment to produce black oxide skin. This hard gray-black oxide scale is mainly composed of NiCr2O4 and NiF, two EO4 components. In the past, hydrofluoric acid and nitric acid were generally used to remove them by strong corrosion. However, this method is costly, pollutes the environment, is harmful to the human body, and is highly corrosive, and is gradually eliminated. At present, there are two main methods for treating oxide scale:


(1) Sandblasting (pill) method: mainly adopts the method of spraying micro glass beads to remove the black oxide scale on the surface.
The mechanical properties of the surface of the workpiece are improved, so the fatigue resistance of the workpiece is improved, the adhesion between it and the coating is increased, the durability of the coating film is prolonged, and it is also conducive to the leveling of the coating and the decorative sandblasting. There are two types of dry sandblasting and wet sandblasting.

 

(2) Chemical method: use a non-polluting pickling passivation paste and a non-toxic cleaning solution with inorganic additives at room temperature for immersion. So as to achieve the purpose of whitening treatment of the natural color of stainless steel. After processing, it basically looks like a dull color. This method is more suitable for large and complex products.
