First, the thickness of welded steel pipes
In the production and use of welded steel pipes, the thickness of the steel pipe is a very important parameter. However, due to production and processing reasons, there may be certain deviations in the thickness of the steel pipe. These standards specify parameters such as size, thickness, weight, and tolerance of welded steel pipes to ensure the quality and safety of steel pipes. The deviation of the thickness of welded steel pipes may have an impact on the quality and safety of steel pipes. If the thickness deviation of the steel pipe is too large, it may cause the bearing capacity of the steel pipe to decrease, thereby affecting the safety and stability of the product.
In order to control the deviation of the thickness of welded steel pipes, international standards usually stipulate the standards for the allowable deviation of the thickness of welded steel pipes. In actual production and use, it is necessary to strictly control and manage according to the standards to ensure the quality and safety of steel pipes.
Second, the mouth of welded steel pipes
In the process of steel pipe welding, another important thing is the treatment of the mouth of the steel pipe. Whether it is suitable for welding greatly affects the quality of the finished product after welding. First of all, there should be no rust, dirt, and grease on the mouth of the steel pipe. These wastes will greatly affect the welding quality, causing uneven welds and fractures during welding, and even affecting the entire welded product. The flatness of the cross-section is also an important matter that must be done before welding. If the cross-section inclination angle is too large, the steel pipe will bend and have an angle, which will affect the use. During welding, the burrs and attachments on the steel pipe fracture should also be checked, otherwise, welding will not be possible. The burrs on the steel pipe will also scratch the workers and damage their clothes during processing, which greatly affects safety.
Third, the weld of the welded steel pipe
The weld of the steel pipe refers to the weld formed by the steel pipe during the welding process. The quality of the weld of the steel pipe directly affects the performance and safety of the steel pipe. If there are defects in the weld of the steel pipe, such as pores, slag inclusions, cracks, etc., it will affect the strength and sealing of the steel pipe, resulting in leakage points, fractures, and other problems in the steel pipe during welding, thereby affecting the quality and safety of the product.
Therefore, during the production and use of steel pipes, strict quality control and inspection of steel pipe welds are required to ensure the quality and safety of steel pipes.
