Substation to 500kv substation frame using more LSG steel pipe, large diameter welded pipe will generally be used in caliber 299mm to 900mm but the wall thickness will certainly not be thick, generally in 6mm-14mm caliber the larger the wall thickness will be slightly thicker, the most common wall thickness of 6mm, 8mm, 10mm, 12mm, […]
The supply of 16mn seamless steel pipe resources is stable. The large iron and steel companies take their own sales logistics as the base and set up the corresponding logistics industrial park, which will take their own goods as the leading, and then introduce the commodity capital of the surrounding iron and steel companies. This […]
In fact, some things are closely related to our life, although we can’t see them, but they are really around us, in our life. In fact, many people may not see the existence of seamless steel tubes, but they are really around us, big or small, and even help their own lives. Just like our […]
In our lives, no matter what kind of place can be seen in the figure of seamless steel pipe, but we really have a very narrow understanding of steel pipe, that there is only one kind of steel pipe, in fact, in our lives there are two kinds of steel pipe, that is, seamless steel […]
As a major basic material for the building materials industry, steel pipe in our domestic demand are very large, and this year, the export of spiral steel pipe is gradually occupying the market position, its industry development trend is fierce, so that people can not help but think: spiral steel pipe compared to ordinary steel […]
The effect of electrostatic spraying of anti-corrosion steel pipe depends not only on the electrostatic spraying equipment and management techniques, but also consider whether the coating varieties used meet the requirements of electrostatic spraying. Electrostatic spraying requires a low resistivity of the coating, the value of 5 to 50MΩ/cm is more appropriate. In addition to […]
Longitudinal welded pipe consumption process is simple, high consumption efficiency, low cost, the development of faster. The strength of spiral welded pipe is generally higher than that of straight seam welded pipe, and it can use narrower billet to consume welded pipe with larger pipe diameter size, and it can also use the same width […]
Spiral steel pipe is a spiral steel pipe welded by active double-wire double-sided submerged arc welding process with strip steel coil as raw material, kneading and forming at regular temperature. The production process is as follows: raw materials, i.e. strip steel coil, welding wire, welding flux. In the input before are subjected to severe physical […]
Spiral steel pipe raw material for strip or coil are hot rolled plate. Spiral steel pipe raw materials Hot-rolled plate, that is, hot-rolled steel rolled steel plate or strip, commonly known as hot plate, usually also rolled written as the word tie, such as hot-tied plate, but all refer to the same hot-rolled plate. Refers […]
At present, the more common length of spiral steel pipe is 12 meters / branch, but there are many other lengths, in order to more accurately know the length of spiral steel pipe, the following are several common methods. 1, camera length measurement. Camera length measurement is the use of image processing to achieve the […]
