Straight seam steel pipe the cause of the wrong side
Straight seam pipe in the production, the wrong side have occurred, many of its influencing factors. In production practice, often by the wrong side of the error so that steel pipe demotion. Therefore, it is necessary to analyze the cause of the wrong edge of the straight seam pipe and the precautionary measures.
1.the sickle bend steel strip is the most important factor in the wrong side of the pipe. In the spiral pipe molding, the sickle bend steel strip will continue to change the forming angle, resulting in weld gap changes, resulting in open seam, the wrong edge or even take the edge. Seriously affecting the quality of the steel pipe, so the observation of the sickle bend after the uncoiling of the steel strip, by controlling the vertical roller so that the disc can be cut off part of the sickle bending and forming angle of the continuous control and correction is to reduce the production process sickle bend The wrong way to create an effective way.
2.due to the non-trimming of steel head and tail shape and size of poor accuracy, easy to cause when the steel strip bending caused by the wrong side.
3.the head and tail of the steel butt welding weld residual height larger, over-molding if handled properly, likely to cause greater wrong edge.
4.the edge of the strip poor condition is another important reason for the wrong side.

The difference between galvanized steel pipe and black steel pipe
The carrying work of water and gas for residential homes and commercial buildings would be depend on various pipes like seamless steel pipe, ERW steel pipe, galvanized steel pipe as well as black steel pipe. We know that water and gas would be essential for human needs and what's the difference for different pipes? Today, we would have a comparison for galvanized steel pipe and black steel pipe.
Galvanized pipe: Covered with a zinc material, galvanized steel pipe would be have the character of more resistant to corrosion. At first, galvanized pipe is just used to carry water to homes and commercial buildings. The zinc also prevents the buildup of mineral deposits that can clog the water line. Galvanized pipe is commonly used as scaffolding frames because of its resistance to corrosion.
Black Steel Pipe: Different from galvanized pipe, black steel pipe is non-coated. The dark color comes from the iron-oxide which is formed on its surface during manufacturing. The purpose of the black steel pipe at begging is to carry propane or natural gas into residential homes and commercial buildings. It is produced without a seam, making it a better pipe to carry gas. The black steel pipe is also used for fire sprinkler systems because it is more fire-resistant than galvanized pipe.
With time goes on, there is no doubt that technology has gained big progress. Thus the usage of each kind of steel pipe would be wide than before, so do for these two kinds of pipes.

Distinguish between ERW pipe and spiral welded pipe
We would like to say that the building’s exterior is beautiful when we see one. Of course, the exterior good look is also concluding the shape of various steel pipes like ERW steel pipe, spiral welded pipe which are used for water, oil and gas transportation.
No matter which kind of steel pipe you choose for your engineering project. The poor-quality steel pipes would be ousted from the group. So how could we figure out our demands for exact engineering project or estimate houses? Comparison would be one of the top choice for us.
Straight seam high frequency welded pipe, made by welding and induction, is classified different exposure to welding in two forms, hot and cold rolled. For hot rolled coils as raw materials, with other processes like continuous molding, welding, heat treatment, sizing, straightening, there is no doubt that ERW steel pipe is used for low pressure liquid delivery, such as water, gas, and oil.
For spiral welded pipe, with the characters of short, high dimensional accuracy, uniform thickness, surface quality, there is no doubt that it can hold on higher pressure than ERW steel pipe. Thus, we can choose the spiral welded pipe for the high pressure engineering project rather than the ERW steel pipe when we meet this situation.

How to calculate the weight of carbon steel pipe?
You may know a lot of knowledge about carbon steel pipes, you maybe a professional engineer about the production process of carbon steel pipes, but do you know how to calculate the weight of carbon steel pipe? Today, we’ll talk about some ways to calculate the weight of carbon steel pipe.
For round steel pipes, we know that theoretically, the weight of round steel pipes should be the weight of outer diameter cylinder minus the weight of inner diameter cylinder. We all know the density of carbon steel pipe is 7.5 tons per square meter. The outer diameter cylinder’s volume times carbon steel pipes density minus inner diameter cylinder’s volume times carbon steel pipes density should be the theoretical weight of carbon steel pipes. But there are also a common recognized way to calculate the weight of carbon steel pipe: first, outer diameter minus wall thickness. Then used the result times the wall thickness. Then times 0.0246615. This is the result for carbon steel pipe’s weight KG per meter.
For square and rectangular steel pipe, there is also a simple way to calculate the weight. First, perimeter divide 3.14, use the result minus wall thickness. Then use the result times wall thickness, then times 0.0246615. This is the weight for square and rectangular carbon steel pipe.
So do you know about how to calculate the weight of carbon steel pipe for now? Contact us if you have any other problem.

Factors attribute to dielectric corrosion for steel pipe
Due to the complex elements in soil and water, there is no doubt that different corrosion is occurring in innumerable steel pipes like seamless steel pipe, galvanized steel pipe as well as ERW steel pipe.
How could we figure out the relevant factors attributing to dielectric corrosion for steel pipe and keep it from the faster corrosion? Sara thinks that research for different environment is necessary.
Seawater, for instance, would be much more likely to promote dielectric corrosion than distilled water. Under this situation, we should pay high attention to the high quality of the steel pipe if we know they are produced for the deep sea project.
The temperature of the electrolyte also is a factor - the higher the temperature, the more aggressive the corrosion. In the ground water business, we usually are dealing with relatively cool water temperatures. Thus, different temperature would need different steel pipe equipment for the specific environment.
