Seamless steel pipe, manufactured in Threewaysteel pipe company, has various standards with different production process. Today, we would list a detailed diagram for customers to choose from.
Seamless steel pipe can be made by material of carbon, alloy and so on. Here is the list for them:
Boiler Steel Pipe:
Application: Boiler, Super Heater, Heat Exchanger, Ship Builders, Automotive Industry, Power Generation, Food Industry, Paper Industry, Pharmaceutical Industry, Chemical Industry, Oil and Gas Industry
Standard: ASTM A213, ASTM A312, ASTM A269, ASTM A778, ASTM A790, DIN 17456, DIN 17458, GB/T14976, GB/T13296, JIS G3459, JIS G3463, EN 10216-5; GOST 9940; GOST 9941
Out Diameter: 6mm~762mm (NPS:1/8"~30")
Wall Thickness:1mm - 50mm
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.
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.
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.
One of clients asked if we can provide the sample of ERW steel pipe with standard DIN for him. Actually, it is our professional skilled producing these steel pipes nowadays. Today, we would like to introduce the standard DIN 2458 for ERW steel pipe in Threewaysteel.
With 25 year's cumulative experience of producing various steel pipes like seamless steel pipe, ERW steel pipe, galvanized steel pipe and SSAW steel pipe, we can say that we are proud in manufacturing these steel pipes. Of course, this also makes us offer a wide range of ERW steel pipe including standard API 5L, API 5CT, ASTM 53, EN10217, DIN 2458. IS 3589, JIS G3452, BS1387 and so on. It is produced by highly skilled and professional team members in Threewaysteel who have thorough knowledge of the prevailing industrial demands. You can see a big banquet once you entering the steel pipe's factory of Threewaysteel. For this DIN 2458 for ERW steel pipe, it is available in various specifications to provide a wider range of options to choose from.
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.

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.
A confession coming from SSAW steel pipe touches me deeply. She said that she was afraid of being rejected due to the short-back of my unstable of pressure taking like the seamless steel pipe and so on.
As your friend, I would like to say that thank you. Without you, our life would not be so easy and colorful.
