The consumption of galvanized pipes is made by degreasing, washing, pickling, drying, hot galvanizing, zinc blowing, cooling, trademark printing, inspection and packaging of welded pipes. Galvanized pipes processed by welded pipes have the function of anti-rust and anti-corrosion. Although its pollution is very serious, there is no pipeline in the market that can be completely replaced at present: the main uses of galvanized pipes are as follows:
1. Fire engineering: Today's fire water supply pipes are basically galvanized pipes. The common main body of fire pipes: mainly used for DN100*4.0 and DN150*4.5 national standard galvanized pipes to reach 1.6pa pressure. The national standard rules are to use the national standard thickness, ability as the main fire pipe, but in practice can also be used in accordance with. According to the floor of my practice, the scope of acceptance pressure of practice, can choose the corresponding thickness, can reduce the cost accordingly! Nowadays, no matter most of the fire pipes, or the fire pipes in the open room, basically use galvanized pipes, and then coat the outer layer of galvanized pipes with a layer of paint, so that you can often see the red fire pipes, in fact, they are only made up of galvanized pipes.
2. Steel structure, welding engineering: nowadays, many factory buildings outside are built with welded steel pipes, but welded steel pipes are easy to rust, in order to avoid rusting and coat a layer of paint, in order to solve this problem, many new steel structure projects are directly using galvanized pipes, which can save labor. When it takes a long time, ordinary welding projects will use comparatively thin galvanized pipes, which are basically two levels under the national standard, and the requirements for steel pipes are not so high.
3. Agricultural pipes: Speaking of agricultural pipes, many people are still very unfamiliar. Many people think that bamboo wood is directly used in agriculture. Nowadays, galvanized pipes are directly used in agricultural pipes. They are mainly used to build thermal greenhouses, to build flower shed, and to make pillars for flowers and melons. Most of them are galvanized pipes with 4 * 1.7 thickness and 6 * 1.7 thickness. They have a simple request for galvanized pipes to be able to bend, so the timing of material selection is also very important!
