Spiral steel pipe connection methods
Generally speaking, the connection method of spiral steel pipes is welding, because welded pipes are relatively low-cost. Some projects will also use other connection methods such as threads due to construction period, construction conditions, geographical environment, and other factors. Connecti...Read more -
Causes of trachoma in welds of spiral submerged arc welded steel pipes
Spiral steel pipe is made of strip steel that is bent in a spiral direction through a rolling machine and then welded by capacitor double-sided submerged arc welding. During the welding production process of spiral steel pipes, many galvanized channel steel problems such as missed welds and misal...Read more -
How does the hot-rolled steel pipe process affect the quality of steel pipes
The impact of hot-rolled steel pipe technology on steel pipe quality is mainly reflected in the following aspects: 1. Rolling temperature: Rolling temperature is one of the most important parameters in the hot rolling process. If the temperature is too high, the steel may overheat, oxidize, or ev...Read more -
What are the advantages of using a 3pe anti-corrosion straight seam steel pipe
3pe anti-corrosion straight seam steel pipe is made of three layers of polyethylene or polypropylene wrapped around the outside of the steel pipe. Commonly used base materials include spiral pipes, seamless pipes, straight seam pipes, and galvanized steel pipes. Among them, galvanized steel pipes...Read more -
Details of anti-corrosion treatment of large diameter thick wall spiral steel pipe
Anti-corrosion spiral steel pipe is to carry out anti-corrosion treatment on spiral steel pipe. The main anti-corrosion method is polyurethane anti-corrosion spiral pipe. After preliminary treatment such as rust removal, the steel pipe is first put on a polyethylene jacket. The thickness is deter...Read more -

Common pipe simmering equipment for steel bending pipe
Steel bending pipe bending is divided into two types: cold simmering and hot simmering. Cold simmering is to bend the steel bending pipe at normal temperature. There is no need to fill the pipe with sand, and there is no need to heat the simmering steel bending pipe section. It is easy to operate...Read more -
What are the requirements for surface treatment of galvanized steel pipes
There are many requirements for the surface treatment of galvanized steel pipes, as follows: 1. Cleanliness: The surface of the steel pipe should be cleaned of oil, dust, oxide scale, welding slag, and other impurities to ensure that the galvanized layer is closely combined with the surface of th...Read more -
Materials and characteristics of H beam steel Q355
When we talk about H-beam steel Q355, we are talking about steel with specific materials and properties. H beam steel, as a high-efficiency profile with an economical cross-section, is named after its cross-section is the same as the English letter “H”. It is widely used in large stee...Read more -
Measures to deal with common problems of straight seam steel pipe pre-welding
1. Wrong side. This is a common problem in pre-welding. Misalignment of edges will directly lead to the downgrading or scrapping of steel pipes. Therefore, it is required to strictly control the amount of edge deviation during pre-welding. When the entire or more than half of the steel pipe blank...Read more -
Will stainless steel channel steel be corroded
Stainless steel channel steel, as a common metal product, is usually used in various structures and devices and has high corrosion resistance. However, whether it will corrode depends on a combination of factors. First of all, the reason why stainless steel channel steel can resist corrosion is b...Read more -
What are the differences between seamless steel pipes and welded steel pipes
Seamless steel pipes and welded steel pipes are commonly used materials in our daily lives and industrial production, and they play important roles on different occasions. Although the two seem similar, they are very different. First of all, from the appearance point of view, the surface of seaml...Read more
