316L stainless steel Glossy surface nipple coupling for Electricity Industry
Threaded coupling 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.
Glossy surface refers to a bright surface, which has a highly polished effect, has excellent reflection characteristics, and is bright and dazzling like a mirror surface.
Chemical polishing is a polishing method in which metallographic samples are immersed in a formulated chemical polishing solution, and the surface is polished by the dissolution of chemical agents. Chemical polishing is one of the common polishing methods for metallographic samples. This method is easy to operate and does not require any equipment. You only need to select an appropriate chemical polishing solution and master the best polishing specifications to quickly obtain an ideal smooth and clean surface. Surface without deformation layer.
1: Sample preparation: the sample is cleaned after being polished.
2: Configure chemical polishing solution. The chemical polishing solution should be prepared in a beaker, and the chemical polishing solution formula should be selected according to the sample material. Distilled water should be used when preparing the solution, and chemical pure reagents should be used for medicines. Certain medicines that are not easily soluble in water need to be heated to dissolve the solution. Hydrogen peroxide and hydrofluoric acid are very corrosive, so pay attention to safety when preparing them. After the chemical polishing solution is used, the metal ions in the solution increase, and the polishing effect is weakened. If the effect is slow and the bubbles are reduced, the new chemical solution should be replaced.
3: Clamp the sample with bamboo clamps or wooden clamps and immerse it in the polishing liquid, stir and take it out in due course, and take it out after it reaches the polishing requirements.
4: After the chemical polishing, the sample should be cleaned and blown dry immediately.
