Jinghua Steel Pipe Co., Ltd. Liaocheng a variety of customized hot galvanized seamless steel tubes, cold galvanized seamless steel tubes, high pressure seamless steel galvanized, hot galvanized precision tubes, color coated tubes, the development of the zinc layer material to meet increasing various use conditions, extend the life of galvanized steel, zinc layer material is constantly evolving. Major new coatings are: (1) a zinc-iron alloy coating. That galvanized steel after heat treatment. As carried out at 500 ~ 550 ℃ diffusion annealing 10 ~ 15min, it will give the galvanized pipe in oilfield extend the life of nearly 9 times; (2) Multiple or contain traces of alloying elements zinc coating. Such as adding an appropriate amount of nickel allows the corrosion resistance than pure electro-galvanized pipe more than 10 times; (3) composite coatings. That is according to the conditions of use desired, finishing galvanized seamless steel tubes, the steel galvanizing layer coated with a suitable organic material, such corrosion, high temperature resistance, cold resistance, wear resistance, impact resistance and increase the elasticity aspect, precision galvanized seamless steel tubes, can further meet one or several higher requirements. If color coating, as well as decoration and signage effects. Jinghua Steel Pipe Co., custom-made thick-walled seamless steel galvanized, hot-dip galvanized thin-walled seamless steel tubes, Jinzhou galvanized seamless steel pipe, hot galvanized seamless steel pipe and galvanized pipe must be seamless hot-dip galvanizing Well, his strength than ordinary galvanized pipe, galvanized pipe ordinary Longitudinal generally. Seamless galvanizing are carried out under the requirements of customers, the market is not galvanized seamless pipe spot. This mainly depends on your purpose, if not bad money, then of course, hot galvanized seamless pipe.
