Galvanized pipe fittings are galvanized, including galvanized elbow, galvanized reducer, galvanized flange, galvanized elbow, galvanized pipe cap head. It has the advantages of uniform coating, strong adhesion and long service life. A zinc ferroalloy layer with compact structure is formed by complex physical and chemical reactions between the tube substrate and the molten bath. The alloy layer is integrated with pure zinc layer and pipe body. Most of the galvanized pipe fittings are used in gas, heating and other pipeline projects. If the steel pipe body needs to be galvanized, the corresponding connecting pipe fittings should also be galvanized. The cost of galvanizing is low and the surface is not very smooth. The main purpose of galvanizing is to enhance the ability of the pipe itself. The main production process of hot-dip galvanized pipe fittings is as follows: degreasing → rinsing → pickling → cleaning → dipping plating AIDS → hot air drying → hot dip galvanizing → internal and external blowing → cooling → passivation and rinsing.
Malleable cast iron (Maanshan Steel) pipe fittings are made of malleable cast iron, which are connected with the pipe by thread (screw thread), so that the pipe can be in good contact and connection. The working pressure of this kind of pipe fitting is generally within 0.1MPa. Do not use it under extremely high pressure to prevent some abnormal events. Malleable cast iron (MAANSHAN) pipe fittings are characterized by thick edges at the ends. In order to increase the connection strength, it is mainly used for the extension, branch and turning of the pipeline.
