Some characteristics of small diameter pipe welding machine roller
In the 1980s and 1990s, with the transformation of domestic welded pipe factories and the construction of joint venture welded pipe factories, a large number of foreign-made welded pipe sets entered China. They come from Western developed countries such as the United States, Japan, and Germany.
These welded pipe groups mainly produce small-caliber thin-walled furniture pipes and special-shaped pipes. At the same time, they also introduced many road rollers. The manufacturer reflects that the performance of the main belt roller is better than that of the domestic processing roller. what is the reason?
Over the years, they have had the opportunity to visit some joint-venture welded pipe factories. They watched many imported welded pipe production lines, contacted manufacturers and technicians, and put forward some technical suggestions. Questions were exchanged. The general impression is that foreign colleagues attach great importance to the forming method of welded pipes, try to make the force distribution of the rolls more reasonable during the forming process, and also attach great importance to the design, configuration, material selection and processing methods of the roll passes.
There are many unique opinions about volumes. There is no doubt that it plays an important role in ensuring the quality of rolls. Some are used for small diameter coils. It plays an important role in ensuring the quality of rolls. Some are used for small diameter coils. It plays an important role in ensuring the quality of rolls. Some imported welded pipe rolling mills for small diameter coils have characteristics in material selection, processing method pass design, pass configuration and roll structure, etc., which can be used for reference by domestic and pipe mills to improve the quality of China’s welded pipe rolls. .
