Nowadays, there are three main products in the water heater market: gas water heater, electric water heater and solar water heater. Solar water heater is usually composed of collector, adiabatic storage tank, connecting pipe, bracket and control system. Among them, vacuum tubes, water tanks and other accessories are rectangular galvanized tubes. However, the demand for galvanized steel pipes varies with different manufacturing processes.
At present, the demand situation in the occupation is that some famous enterprises have relatively stable demand for galvanized steel pipes and dredged channels, so the quality is also guaranteed.
Although the solar energy production profession is a new channel for the sale of galvanized pipes, how to consolidate and stabilize this sales chain should be considered for galvanized pipes. At the same time, the profession of solar energy production should standardize the technology and information within the profession.
Why galvanized steel pipe should not be welded again after cutting: because galvanized steel pipe should not be welded again after cutting, the first thing is that welding together will not achieve the previous effect. First, the galvanized layer at the welding site will be damaged and toxic gases will appear in the welding process, and the welding function is not good. Second, galvanized steel pipes rely on the protection of galvanized layer to avoid corrosion, so it is simpler to cause corrosion of steel pipes. It is not recommended that galvanized steel pipes be welded together if they are cut.
Discrimination of galvanized pipes: Galvanized pipes on the market are mainly divided into hot-dip galvanized and galvanized. Because zinc hardly changes in the air, if we cover a layer of zinc on the steel pipe, we can avoid the corrosion of the steel pipe in the air. This kind of steel pipe is called galvanized pipe. The galvanized pipe has excellent functions relative to other pipes. So when choosing galvanized pipes, how to distinguish the quality of galvanized pipes? Let's see how the galvanized pipe manufacturer distinguishes. Let's share his experience.
1. Appearance lubrication, no zinc tumors, burrs, silver white;
2. The thickness is controllable and can be chosen arbitrarily within 5-107 um.
3. No hydrogen embrittlement and no temperature hazard can ensure that the mechanical function of data remains unchanged.
4. Good corrosion resistance, neutral salt spray test up to 240 hours.
Here, galvanized pipe manufacturers also remind us that they say that every penny is a penny for a penny. When choosing galvanized pipe, we should remember that the goods are more important than the three.
