Factors affecting the performance of galvanized steel pipe

One is carbon: the content of carbon will affect the hardness of steel. The higher the content of carbon, the better the hardness, but at the same time its toughness also deteriorates. The content of sulfur and phosphorus is also one of the indicators that affect the performance of galvanized steel pipes. Appropriate content can improve the machinability of the steel, but at the same time it also reduces the toughness and plasticity of the steel. Chromium can make galvanized steel pipes have better wear resistance and enhance their corrosion resistance. In addition, silicon, tungsten, chromium and other elements will also affect its performance.


The second is the material: the material is different, the specification is different, and the scope of use is also different. There are also many differences in materials. Some of them are made of pure broken, and some are produced with trial plates. The products of galvanized steel pipes such as 369 and other products also give suppliers and users a lot of choice.

Unique cleaner production


The galvanized steel pipe adopts the sulfate electrogalvanized zinc-iron alloy process, which is that the production line groove and the groove are perforated and straight, and the solution is not carried out or overflowed. Each process in the production process is composed of a circulation system. Each tank solution, namely acid and alkali solution, electroplating solution, light extraction and passivation solution, etc., is only recycled and used without leakage or discharge to the outside of the system. The production line only has 5 cleaning tanks, and the circulation is adopted. Reuse the regular discharge, especially the production process without waste water that is not cleaned after passivation.
