How to choose galvanized pipe can be suitable for itself? According to different requirements, different main uses should be selected according to the specific situation. Here, we will explain to you the galvanized pipe manufacturers.
1. Steel is different. Of course the steel ones cost more.
2. Different specifications and models. Different wall thickness, net weight and other reasons lead to different prices.
How to choose galvanized pipe can be suitable for itself?
3. The norms are different. Different standards stipulate different prices.
4, different classification is used in different main purposes, so the price is not the same.
Surface treatment of anticorrosive galvanized pipe:
1, according to the power of the motor to promote spraying (throwing) jet blade surface high-speed operation, so that steel sand, steel ball, steel wire section, minerals and other wear-resistant materials under the action of the force of the anti-corrosion pipe surface spraying (throwing) solution, not only can completely remove rust, metal oxide and waste, and anti-corrosion pipe in the wear-resistant material strong impact and friction effect, It can also achieve the necessary symmetrical surface roughness.
2, the use of organic solvents, solvents to clean the surface of anti-corrosion galvanized pipe, that can remove the surface of galvanized pipe organic compounds, but it can not remove its surface rust, oxide skin, welding powder, so cleaning only as a way to assist the application.
3. Use steel brush, grinding sandpaper and other special tools to polish and polish the surface of anti-corrosion galvanized pipe, which can remove loose oxide skin, rust, welding scar and so on.
4. Organic chemical pickling passivation is selected for anticorrosion of steel pipe, which can remove oxide skin, rust and old coating, and make the surface to achieve a certain cleanliness and surface roughness.
