In the meanwhile, taking into account the different application requirements, Tianjin steel tube manufacturers always try to carry out the standardized production, and provide customized specifications of the products always. How to look at Tianjin steel pipe challenges in 2019?

Galvanized steel pipes have long been used as one of the most used building materials around the world. For decades, designers, builders and consumers seeking long-term structural performance in the harshest of outdoor applications have turned to zinc-coated steel pipes. Zinc-coated galvanized steel pipes can resist the attack of wind, water and road salts. It may be used in residential water supply lines, but not gas lines because natural gas causes the zinc to flake off and clog the system. However, it's not frequently used for water supply lines because the minerals in the water react with the galvanizing material and form scale, which builds up over time and will eventually clog the pipe. Galvanized pipe was commonly used for water supply lines many years ago, but over time many have filled with scale, which is why some older homes suffer from low water pressure. Hard water greatly reduces the life of steel pipe. In addition, galvanizing alloy layer mainly depends on the thickness of the silicon content of the steel chemical composition, the rough degree of the size of the cross-sectional area of the steel surface, the temperature of the zinc pot, the zinc immersion time, the cooling speed, and the cold deformation. In that regard, Tianjin China hollow section manufacturers should try to meet customers’ various needs as per the specific pipe specifications.

In recent years, galvanized steel pipe is confronting increasingly fierce competition in the steel pipe market. It is high time for steel pipe manufactures to act immediately so as to increase their competitive power in 2019. It is believed that only with high quality products, can steel pipe manufacturers gain the wider space to have further advancement in future. Furthermore, it is important for pipe enterprises to pay much attention to the continuous improvement of the whole strength so as to form their own feature brand. As all insiders know, hot dipped galvanized steel pipe is a special type of pipe due to its relatively complex processing in the steel market. For the same one specification of pipe, there exist certain difference between the international standards and the domestic standards. In that regard, it is strongly suggested that tube manufacturers should try to provide qualified products, in order to leave customers a good impression.
