Cooling method plays an important role during the production process of seamless steel pipe. As some defects may happen during the cooling process if we donâ??t take the rightful plans for it. So we should have a clear understanding for the cooling methods before the production of steel pipe. There are three main categories for cooling method: 1.Air cooling: according to the literal meaning, we can know the method easily. It is a kind of natural cooling method as we just need to put the steel pipe into the air. To some extent, it is a widely used way to cool steel pipe after hot rolling. 2.Fast cooling: this is the cooling method with the process of blowing, spraying and water. We can use fast cooling if we are in need of fast done for the product. Depend on the cold water, we can lower the temperature quickly than air cooling method.

Each kind of test measurement such as Technical Properties (Flattening Test, Bending Test, Blow Test, Impact Test), Exterior Size Inspection, Hydrostatic Test, X-ray Test would be necessary for guarantee of the high quality of steel pipe like seamless steel pipe, galvanized steel pipe. There are some characteristics for visual inspection of non-destructive testing: 1.Weld surface defects test: surface cracks would be the first step for check of the steel pipe and then the impermeability and weld quality of the leak. 2.Detailed exam for raw material for steel pipes production, such as the surface cracks, peeling, cables, scratches, dents, bumps, spots, corrosion and other defects. 3.Cavity detection. This test would carry out according to the engineering projects demand and the engineers requirement. 4. Additional material inspection. Inspect the product for dust, foreign matter and other residues in the cavity.
No matter which kind of steel pipe, seamless steel pipe, or ERW steel pipe, or straight seamless welded pipe, there is the pipe forming demands for them in order to have the best quality when they applied in various engineering project. Here is the list for welded steel pipeâ??s joint surface demands for manufacture and this would lead customers to figure out the better steel pipe too. 1.It is not allowed for cracks, pores, slag, lack of fusion, spatter during the production process. 2.Temperature would be controlled strictly. For example, we should figure out the different temperature for surface treatment about Fusion bond Epoxy coating, Coal Tar Epoxy, 3PE, Vanish Coating during the whole production. 3.It is necessary to notice that we should keep the whole temperature must not be lower than the surface of the weld surface of the pipe. For example, some of the welding reinforcement does not exceed 3mm (the maximum width of the weld after the groove). We have to pay high attention to every step during the production process in order to have high quality steel pipes for customers.
As the saying goes that To be is to be perceived. You would feel it if we cannot describe it sometimes. This is for air, water, seamless steel pipe and so on.

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.

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 the saying goes that different strokes for different folks. So does for the choosing of pipes for residence and commercial places. We would like to choose the different pipes according to our taste, pipes function and other factors. For Sara, it would be a consideration for the steel pipe like the galvanized steel pipe. However, which kind of material would you like to choose for your water pipe? Here are some sharing for all of friends. No matter hot or cold water, there is system generally conveying potable hot and cold water. They are applied in drinking water supply, cooking, and cleaning within in residential, commercial, institutional, and industrial buildings. There are several categories for pipes, such as copper pipe, CPVC pipe, galvanized steel pipe, PEX tubing, PVC pipe and stainless steel pipe. Each of them would have special power once you choose it. For example, copper is a long lasting, corrosion resistant, lightweight and strong material used in pipes making. However, we all know that we would decide the pipes option according to price, quality, function and other factors.
