Galvanized pipes are widely used in various industries, and now the solar energy production industry has also been well used.
Today, the water heater market mainly has three main types of products, namely gas water heater, electric water heater, solar water heater. The solar water heater is usually composed of a collector, an adiabatic storage tank, a connecting pipe, a support and a control system. Among them, vacuum tubes, water tanks and other accessories are rectangular galvanized pipes. But different manufacturing processes have different requirements for galvanized steel pipes.
The current demand situation in the industry is that some famous-brand enterprises have relatively stable demand for galvanized steel pipes and smooth channels, so the quality is guaranteed.
Although the solar energy production industry is a new channel for sales of galvanized pipes, how to consolidate and stabilize this sales chain should be considered. At the same time, the solar energy production industry should regulate the technology and materials in the industry.
Why galvanized steel pipes should not be re-welded after cutting: because galvanized steel pipes should not be re-welded after cutting, mainly because welding together will not achieve the previous effect. First, in the welding process, the galvanized layer will certainly be damaged and there will be toxic gases, poor welding performance. The two is galvanized steel pipe is galvanized layer protection against corrosion, so that it is more likely to lead to corrosion of steel pipe. If galvanized steel pipe is cut, it is not recommended to be welded together.
Galvanized pipe identification: now the galvanized pipe on the market is mainly divided into two types of hot dip galvanizing and galvanizing. Because zinc is hardly changed in the air, if we coat the steel tube with zinc, we can prevent the corrosion of the steel tube in the air. This kind of pipe is called galvanized pipe, and the galvanized pipe has excellent performance compared with other pipes. How to distinguish the advantages and disadvantages of galvanized pipes when choosing galvanized pipes? Let's take a look at how galvanized tube manufacturers are identified. Let's share his experience.
1, smooth appearance, no zinc tumor, burr, silver white;
2. The thickness is controllable and can be selected within 5-107 m.
3, no hydrogen embrittlement, no temperature hazards, can ensure that the mechanical properties of materials remain unchanged.
4, good corrosion resistance, neutral salt spray test for 240 hours.
Here, galvanized pipe manufacturers also remind everyone that is a penny a cent, we should remember to purchase galvanized pipe than three Oh, the quality of the most important
