1. Different production processes
Galvanized steel pipe and seamless steel pipe are two ranges of steel pipe. Galvanizing refers to the solution of steel pipe surface galvanizing, including welded steel pipe and seamless steel pipe. Seamless welding refers to the production and processing technology of steel pipe, including electric welding and seamless welding.
2. Different process properties
Galvanized pipe is corrosion resistant, and seamless steel pipe bears high working pressure. Galvanized steel pipe has zinc maintenance and is not easy to rust. Galvanized steel pipe is lighter than seamless steel pipe. If it is used for living balcony, it is better to use galvanized steel pipe. Seamless steel pipe is not suitable for living balcony.
The wall thickness of seamless steel pipe, of course, is very heavy, and the cost of seamless steel pipe is higher than that of galvanized steel pipe. The durability of galvanized steel pipe is much longer than that of seamless steel pipe.
3. Different main purposes
The surface of galvanized steel pipe has hot crossover or galvanized layer electric welding steel pipe. Galvanizing can improve the corrosion resistance and prolong the service life of steel pipes.
Galvanized pipes are mainly used for a wide range of purposes. In addition to general bottom pressure fluid pipes such as water, liquefied gas and oil pipes, they are also used as fixed support pipes for petrochemical industry, especially for oil and gas well pipes, oil pipelines of deep-sea oil and gas fields, heat transfer oil heaters, cooling towers, coal distillate washing oil exchange pipes, prefabricated piles for trestle roads, and coal mine pipes for coking equipment in chemical plants.
It is often said that galvanized pipes are very important to transport natural gas and heating. As a water pipe, the galvanized pipe has been used for many years. The yellow liquid discharged from the pipe has not only polluted the cleaning equipment, but also rusted the pathogenic bacteria propagated in the inner cavity. The excessive heavy metals in the water pose a serious threat to the physical and mental health. In the 1960s and 1970s, international capitalist countries gradually developed galvanized pipes.
