| Product Introduction | |||||||||||||||
| Galvanized elbow is a type of elbow that involves coating the surface of the elbow with a layer of zinc material, achieving its corrosion resistance, aesthetics, rust prevention, and other functions. Galvanized elbows are divided into two types: hot-dip galvanizing and electrogalvanizing. The hot-dip galvanizing layer is thick, the cost of electrogalvanizing is low, and the surface is not very smooth. Connect two pipes with the same or different nominal diameters to make turns at 90 °, 45 °, 180 °, and various degrees. Bending radius less than or equal to 1.5 times the pipe diameter is considered an elbow, and bending radius greater than 1.5 times the pipe diameter is considered an elbow. | |||||||||||||||
| Hot dip galvanizing industry | Hot dip galvanized elbow: Hot dip galvanized elbow is formed by three steps of zinc in liquid state, and the surface of the elbow is dissolved by zinc liquid to form a zinc and iron alloy phase layer; The zinc ions in the alloy layer further diffuse towards the elbow substrate to form a zinc iron mutual solution layer; The surface of the alloy layer is wrapped in a zinc layer. Hot dip galvanized elbows have a thick and dense pure zinc layer covering the surface of the elbow. Galvanized elbows can avoid contact with any corrosive solution and protect the elbow substrate from corrosion. In the general atmosphere, a thin and dense layer of zinc oxide is formed on the surface of the zinc layer. It is difficult to dissolve in water, so it plays a certain protective role on elbows. If zinc oxide forms insoluble zinc salts with other components in the atmosphere, its anti-corrosion effect is more ideal. | ||||||||||||||
| Cold galvanizing process | Cold galvanizing: Cold galvanizing, also known as electrogalvanizing, is the use of electrolytic equipment to remove oil, acid wash, and then put the pipe fittings into a solution containing zinc salt. The negative electrode of the electrolytic equipment is connected, and a zinc plate is placed opposite the pipe fittings. The positive electrode of the electrolytic equipment is connected to the power supply, and a layer of zinc is deposited on the pipe fittings by using the directional movement of the current from the positive electrode to the negative electrode. Cold galvanizing elbows are processed first and then galvanized. The zinc coating is thick, with fine and uniform crystallization without pores, and has good corrosion resistance; The zinc layer obtained from electroplating is relatively pure and corrodes slowly in acid, alkali, and other mist, effectively protecting the base of the elbow. The galvanized elbow forms white, colored, military green, etc. after chromate passivation, which is beautiful and elegant, and has a certain degree of decoration. Due to the good ductility of the galvanized elbow, it can be formed through various processes such as cold stamping, rolling, bending, etc. without damaging the coating. | ||||||||||||||
| Product Function | (1) The density of galvanized elbows is only one tenth of that of elbows, and they are lightweight. (2) It has unique impact strength performance and is significantly improved compared to other bent pipes. (3) The elbow manufacturer believes that galvanized elbows have a long service life, and as long as they are used within the specified temperature and pressure range, their service life can reach 50 years. (4) It has the function of preventing ultraviolet rays and radiation, and galvanizing bends and fades. It can also withstand the erosion of various chemical substances, has good acid resistance, corrosion resistance, and alkali resistance, and will not breed bacteria and rust. There is no electrochemical corrosion. |
