Stainless steel water pipe How to solve the problem of uneven wall thickness? In the process of slitting and welding, it is often found that the wall thickness of stainless steel water pipes is uneven. In fact, it has a great relationship with the plate, so the plate needs to be checked before warehousing. But when the wall thickness of the stainless steel water pipe is uneven, how to solve it? In general, Stainless steel pipe The uneven wall thickness is mainly manifested in the uneven spiral wall thickness, the uneven straight wall thickness, and the uneven thickness of the head and tail wall. The influence of continuous rolling process adjustment is an important factor leading to the uneven wall thickness of finished stainless steel water pipes.

Measures that can be taken for uneven wall thickness of stainless steel water pipes include:

1. Adjust the rolling center line of the piercer to make the inclination of the two rolls equal, and adjust the pipe mill according to the parameters given in the rolling table.

2. The opening time of the centering roll shall be adjusted according to the outlet speed of the stainless steel pipe. The centering roll shall not be opened prematurely during the rolling process to avoid uneven wall thickness caused by the mandrel shaking. The opening of the centering roll shall be properly adjusted according to the change of the capillary diameter, and the capillary runout shall be considered.

The cutting problem of thin-walled stainless steel pipe lies in the cutting of stainless steel. It is recommended to use a saw blade with chrome plating or nitriding treatment. Instead of using titanium plated saw blades, because of the proliferation of counterfeit goods on the market, some operators often use the saw blades with poor materials for steam plating, but because the base material itself is not accurate enough, it fails to provide better cutting results. Moreover, after steam plating, the steel plate is deformed due to heat. A few operators have to overcome the problem by knocking to flatten it. When the saw blade is cut again, the thermal deformation occurs again, The knocking can only last for a short time, not for a long time.

And although stainless steel is difficult to cut, its characteristics are not very solid, mainly because its chips are easy to stick to the tool, so it is classified as difficult to cut. The chrome plated saw blade is designed for the characteristics of stainless steel, with full consideration of friction and cutting. However, the tooth shape is also an important factor affecting the cutting effect, so when purchasing a saw blade, do not forget to indicate that it is used to cut stainless steel, so that it can be distinguished when opening the teeth, so that the stainless steel can be grinded into a special tooth shape. Do not have the wrong idea that a hard saw blade is good, let alone a titanium plated saw blade, which can be used to cut workpieces of all materials, In foreign countries, there are different saw blade designs for different materials. In fact, even titanium plated saw blades have many differences, such as stainless steel for short, but stainless steel 303304316, etc. are also different.
