Just as hot dipped galvanized steel pipes cold galv pipes, the boiler steel plate also has strict control of chemical composition for the material, especially harmful elements such as phosphorus and sulfur, and residual elements such as chromium, nickel, and copper; during smelting, good deoxidation and removal of non-metallic inclusions should be carried out to ensure good quality, plasticity and toughness. The organizational structure requires uniformity, and the grain size is controlled within a certain range; there are also strict requirements for surface quality and internal defects. In addition, the boiler steel plate mechanical properties at room temperature and high temperature must be guaranteed.
What is the difference between hot dip galvanizing and cold hot dipped galvanized steel pipes cold galv pipes
Cold galvanized zinc is just 10-50g/m2, it's own corrosion resistance than hot-dip galvanized a lot of difference. Galvanized by a generally less expensive cost. Hot-dip galvanized steel body is hot-dip galvanized surface under the state of its grip solid, difficult to tumble off, despite the fact that their hot dip galvanized pipe corrosion hot dipped galvanized steel pipes cold galv pipes Related searches hot dipped galvanized steel pipes cold galv pipes

Intro to Hot Dip and Cold Galvanized Steel Pipe - Landee Cold galvanizing is electricity galvanizing, but the galvanized quantity is very few about only 10 g to 50 g per square meter. Its corrosion resistance ability is weaker than that of galvanized pipe. Regular galvanized steel pipe manufacturers mostly do not use electric galvanized zinc (cold galvanized) in order to guarantee the quality.
Hot-dip galvanized steel pipe making process. At first, the steel pipe is pickled, and then cleaning the iron oxide on the pipe surface; it is cleaned in a tank with an aqueous solution of N H 4 Cl and ZnCl 2 or a mixed aqueous solution, and then placed in a hot-dip galvanizing tank for hot-dip galvanizing.

Hot Dip Galvanized Pipe. Hot-dip galvanizing (HDG), as referenced is the process of dipping fabricated steel into a kettle or vat of molten zinc. Galvanizing is one of the most widely used to methods for protecting metal from corrosion.
First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers".
