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.
On the morning of April 10, Chinese President Xi was invited to attend the opening ceremony of boao Asia BBS 2018 annual conference. As steel pipe supplier, from seamless steel pipe to SSAW steel pipe, weâ??ve learned lots from the keywords President Xi said.
Keyword--new age, new mission
We Chinese will continue keep the spirit of constantly strive to become stronger, and become better.
We Chinese will continue keep the spirit of innovation and pushing the development.
We Chinese will continue to keep the expand open, and highlight the cooperation.
As supplier of steel pipes and we have done import business for almost 25 years and it is time for us to follow the step of president to figure out the right way for us to get.

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. Even a child would tell his mother that we can use this tube for water when he plays games.
Seamless steel pipe, coming from Threewaysteel pipe company, with its special characters API 5L: GR B, X42, X46, X56, X60, X65, X70, is here for customers. We cannot see deep seaâ??s oil drilling all the time. However, as my child said that I know we need steel pipe when I have a shower and I need to have the steel pipe when I wash my clothes. We will know its importance in our daily life once the broken steel pipe cannot do any transportation work for us. We may not talk about them all the time, however, we know they are here with us which would give us comfort.
There are some special sectors for engineering projects need erw steel pipe largely. For this point, manufacturer threewaysteel pipe company would have a list for the relative steel pipe produced for customers.
