Weather proof double layer epoxy compound powder Epoxy compound powder coating Introduction The product is a kind of weather proof double layer heavy duty epoxy compound powder, comprises of two layers of primer and finishing, to be applied directly to steel surface after sandblasted and heated. The primer layer is to provide protection for anticorrosion. The finishing layer is anti- scratch, anti-impact, anti-abrasion as the common advantage of epoxy coating, it is also featured with high shinning, uv-resistant, and superior durable, heat resistant, anti-corrosion, anti-powderization. The finishing layer is applied onto the primer layer. Two layers of powder are melted and solidified to an even, dense coating layer with solid jointing between two layers. The powder can be customized to a plenty of color with can, t be get from normal anti-corrosion layer. The coating will not fade, darken fast over time, even for the bright colors like white, light blue, pink, bright yellow.

How could we forget the sulfate galvanized conversion when we talked about the process characters of galvanized steel pipe. Today, as manufacturer of steel pipes, Threewaysteel pipe company would have a list for sulfate galvanized conversion in hot galvanized steel pipe. Sulfate galvanized conversion: Sulfate galvanized ferroalloy retains only the main salt of zinc sulphate zinc sulfate, and the remaining components, such as aluminum sulfate, alum (potassium aluminum sulfate) can be added in the treatment. This would finally lead to the formation of insoluble hydroxide precipitate precipitation. For organic additives, we can add powdered activated carbon adsorption to remove it. Tests showed that aluminum sulfate and potassium aluminum sulfate is difficult to completely remove in once. And this has a certain degree influence for brightness for brightness of the coating, but it is not serious, as it can be taken out of consumption, which make coating brightness can be restored. The solution passed the treatment, according to the new Process ingredients required additional content, that is the final complete the conversion.Stripped Sunflower Seeds
Steel pipe market has improved in the new year of 2018. We can have an analysis from trading volume increasing and demand. It is obvious that we should have a new market plan for various steel pipes, such as seamless steel pipe, SSAW steel pipe too. First of all, with the new year plas taking out, lots of engineering project would be here and thus the dominant orientation of large diameter straight welded pipe steel would be required. So that SSAW steel pipe would be here for customers. Whatâ??s more, the steel trade business would be carry out in the whole world. Under this situation, there is no doubt that to improve the further development of large diameter thick wall welded steel market and other sizes of steel pipe would be another trend for the steel pipe market. With new yearâ??s coming, new market goal would be carry out step by step and what we need to do is just follow our step of production and doing the best job for our clients.
Physics would tell us that degree of agitation have influence for galvanized steel pipe. Why? Here are some details introduction for it. And it would help us to slow the corrosion for steel pipe once we know the principles for damage of the steel pipe. Once we put the galvanized steel pipe on water, high water velocity can lead the quick erosion corrosion. Thus, here are the troubles caused by scouring of metal surfaces by turbulent water and suspended solids that removes protective scale (12, pp. 2.15, 2.16, 2.25 ; 15, p. 7220). Under this situation, we should know that water movement would have influence for the damage of galvanized steel pipe. As it would lead water aeration to support corrosion. Quickly dissolved oxygen is normal would damage the surface of steel pipe.
As steel pipes supplier, even for ERW steel pipe, we can supply different types with different grade, certification for customers. Today, editor would have a detailed introduction for the physical parameters of ERW steel pipe JIS G3444.
