1. If you use stainless steel hip flasks to hold hot water, be careful to burn your hands, because stainless steel is very thermally conductive.

2. If fingerprints are left on the stainless steel hip flask, you can use an eraser to wipe off the stainless steel hip flask, and then wipe it with a dry cloth.

3. Clean the stainless steel hip flask when you use it for the first time, and clean it when you use it again.

4. When storing the stainless steel hip flask, it is best to blanch it with hot water first, and then dry it and put it away.

Other industries: After the steel pipe is rolled or heat treated, it will inevitably produce bending deformation due to the influence of external force, thermal stress or organizational stress. For the bending deformation of steel pipe ends and large diameter steel pipes, the pressure straightening method is often used for straightening. Traditional pressure straightening often relies on experience to determine the process parameters, coupled with the client's requirements for the ellipticity of the steel pipe, resulting in low straightening accuracy and low production efficiency. The emergence of automatic straightening machines alleviated this situation. This article established a mathematical model for the pressure straightening load-deflection of the thick-walled steel pipe factory and a model for calculating the flattening of thick-walled steel pipes. The hydraulic position servo control system of the automatic straightening machine was established. The controller of the company has been studied to provide a theoretical basis for the development of thick-walled steel pipe pressure straightening machine.
