Galvanized elbow   is divided into electro-galvanized elbow and hot-dip galvanized elbow. Galvanized elbow has the same function to elbow, so what are its advantages over ordinary elbow? The elbow manufacturer   Xiangjiasteel   tells you what are the characteristics of galvanized elbow? 1. The density of galvanized elbow is only one tenth of that of elbow, and its weight is light. 2. Galvanized elbow has a very unique impact strength performance compared to other elbows. 3. Galvanized elbow has a long service life. As long as the galvanized elbow is used within the specified temperature and pressure range, its service life can be 50 years. 4. The galvanized elbow wouldn't fade and able to anti-ultraviolet and anti-radiation. 5. The elbow can resist the erosion of various chemical substances, acid resistance, corrosion resistance, alkali resistance, and won't rust.

Seamless steel pipe   has a hollow section and they are widely used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and some solid materials. Calculation formula for calculating the theoretical weight of common profiles: m=F×L×ρ m—quality Kg; F—cross-sectional area m2; L—length m; ρ—density*Kg/m3 Noted: F calculation method of cross-sectional area: 1. Square steel tube: F= a2 2. Steel pipe: F=3.1416×$(D-$)  D—diameter $—thickness 3. Steel plate, flat steel: F= a×$ a—width

Classification of   rectangular tubes : Seamless rectangular tube and welded rectangular tube, hot rolled seamless rectangular tube, cold drawn seamless rectangular tube, extruded seamless rectangular tube, welded rectangular tube. The rectangular tube. is divided into: (a) According to the process - arc welded rectangular tube, resistance welded rectangular tube (high frequency, low frequency), gas welded rectangular tube, furnace welded rectangular tube (b) According to the welding seam - straight seam welded rectangular pipe, spiral welded rectangular pipe.
