Do you know the way to make spiral steel pipe last longer? In recent years, automotive manufacturers are facing increasing pressure to improve fuel efficiency as people pay more and more attention to environmental issues. Stricter and more stringent regulations have created technical challenges for industrial production and material processing. Among these trends are lower […]
Spiral steel pipe is a spiral seam steel pipe made of strip steel coil as raw material, often warmly extruded, and welded by automatic double-wire double-sided submerged arc welding process. The spiral steel pipe feeds the strip into the welded pipe unit. After rolling by multiple rollers, the strip is gradually rolled up to form […]
The main material of Q345B seamless steel pipe is the Q345B type, which is relatively strong and durable. The common use of Q345B seamless steel pipe is also more, and the wide performance is also relatively good. For Q345B seamless steel pipe, we found that there are more rust, and we must master certain methods […]
With the continuous development of science and industry, it is difficult for ordinary alloys or a single metal to meet the requirements of industrial development for the comprehensive properties of materials. The clad plate made by different processes just meets the special comprehensive performance requirements. The hot-rolled stainless steel clad plate produced by the stainless […]
How to scientifically arrange the production of spiral steel pipes The production of spiral steel pipe is due to its slow adjustment process and fast production. Under normal circumstances, it is not often adjusted, because the adjustment generally requires a half-sound time. If it is produced, this half-sound can produce about 30 tons of steel […]
Galvanized steel pipes are divided into cold galvanized steel pipes and hot-dip galvanized steel pipes. Cold galvanized steel pipes are strictly prohibited from being used, and the latter one is advocated for temporary use in my country. In the 1960s and 1970s, the international bourgeoisie in my country slowly developed designs and designs for new […]
Polyurethane direct buried thermal insulation pipe is suitable for thermal insulation and cold insulation projects of various media in the range of -50℃~150℃. It is widely used in thermal insulation and cold insulation projects in urban central heating, warm room, cold storage, coal mine, petroleum port, chemical industry and other industries. Knowledge of the application […]
Welding process of 304 lined stainless steel composite pipe (304+Q235B) is a new type of composite pipe, which has the characteristics of corrosion resistance, high temperature resistance, high elongation, high strength, etc. It is widely used in the process pipelines of new and expanded petrochemical plants. The biggest use problem of this kind of pipe […]
In order to better improve the tensile strength and wear resistance of the surface of Q345D seamless steel pipe, we need to carry out some surface treatment of metal materials during the production process. Are there any characteristics of Q345D seamless steel pipe? Model specification reliability For precision machining of rectangular square tubes, precision machining […]
The iron oxide scale on the inner and outer surfaces of the hot-rolled tube stock or the in-process tube after the intermediate heat treatment should be removed before the cold working of the ordinary seamless tube. The existence of iron oxide scale, on the one hand, affects the quality of subsequent lubrication; on the other […]
