Application and precautions for galvanized steel pipes, hot-dip galvanized steel pipes are widely used in construction, machinery, coal, chemical, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, mining machinery, etc. 3 inch galvanized steel pipe.
Galvanized steel pipes are welded with hot-dip or galvanized steel. Zinc plating can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes are widely used, in addition to pipelines for general low-pressure fluids such as water, gas, oil, etc., and also used as oil well pipes and oil pipes in the petroleum industry, especially in offshore oil fields, and oil heaters and condensation of chemical coking equipment. Cooler, coal distillate oil exchanger pipe, and trestle pipe pile, support pipe for mine tunnel, etc.
This kind of different types of galvanized steel pipes are produced in some factories that process steel. Let’s use galvanized steel pipes. Please pay attention to what is required when using them. We will discuss the details in detail below. There is also a certain understanding of the price of galvanized steel pipe.
First of all, galvanized steel pipe manufacturers did not add any protective agent on the surface of this product when they produced this product. Therefore, this strip does not have any protective layer when used, so consumers must remember to use it. Before you must add a protective film on the surface of this product, so that the galvanized steel pipe is not used in any environment, it is not worried about any corrosion caused by external substances.
The second is that we should pay attention to when choosing this product in the market. We must choose the surface to be smooth when we choose, without any pitting and small pits, because only the products with smooth surface are selected. It can be proved that the material density of this galvanized steel pipe is relatively small at the time of production without any gap, so that the hardness of the product can be sufficiently ensured.
Galvanized steel pipe letter symbol representation, galvanizing is also called “metal” so it is also called “metal wire pipe”, there are two kinds of thick wall and thin wall, generally used in: lighting, fire, security, video, communications and other power Electrical and control circuit protection. The line tube can be divided into two types, a jdg line tube and a kbg line tube. Many people do not know what the letter symbol on the steel pipe is when buying or using a galvanized line pipe. There are several types of threading pipes, plastic type, galvanized metal type, and various threading pipes have different symbol letters for short, electrical construction drawings will also be marked with letter symbols, this is the wire tube The symbol is abbreviated, so be sure to know what the letter is.
Galvanized wire tube letter symbol representation and classification:
Welded steel pipe (sc), compact galvanized thin-walled wire pipe (JDG), crimped galvanized thin-walled wire pipe (KBG), metal hose (CP), wire pipe / thin steel pipe (tc), galvanized steel pipe ( RC), wire tube (MT).
