Stainless steel undergoes several processes from cutting the steel strip, forming, to welding, and ultimately becoming the welded pipe we want. However, there is a very special process, which is the leveling of the inner weld seam.

Why is this process so special? Because this process is of great significance for the welding quality of welded pipes, it is to remove the unevenness and unevenness of the weld seam, so that we can see that the weld seam is flat and smooth.


The principle of leveling is to use a Hangao leveling machine to perform multiple passes of back and forth pressure rolling on the weld seam, making the welding smooth, and the surface of the inner and outer weld seams smooth, without any layering on the touch.

However, many customers do not have a deep understanding of stainless steel leveling in practical operations, and it is not smooth enough to use.


Now let's talk about some performance advantages of the Hangao machine leveling machine.

The material used for the straightening wheel is solid bearing steel, which is ground and plated with hard chromium after heat treatment. Therefore, the surface of the welded pipe can still be smooth and smooth without any indentation after being straightened by the Hangao leveling machine;

2. The Hangao leveling machine can be flexibly configured and used according to customer requirements;

3. Rotate the handle once to correct that the upper wheel only drops by 1mm, allowing for fine adjustment.

4. Adopting a highly rigid mechanical structure design, the output horsepower is high, the feeding speed is high and stable, the production efficiency is effectively improved, and the machine has a long service life.

5. The electric roller contact and electronic components are all imported from Japan, with low failure rate and long service life.

The Hangao leveling machine is very suitable for high demand welding pipe correction and leveling fields. However, in the daily use of the user's machine, many times they neglect the maintenance and upkeep of the leveling machine, which makes it unable to work smoothly and reduces the machine's work efficiency and leveling accuracy. This needs to be avoided as much as possible.
