[0002] Solution treatment of stainless steel pipes refers to the process of heating stainless steel pipes to a certain temperature to transform their structure into austenite, and then transforming austenite into martensite or other structures during cooling. Solution treatment can improve the strength, hardness and corrosion resistance of stainless steel pipes, and also improve their processing performance. When the stainless steel pipe is solution treated, it needs to be clamped into the furnace with a clamp. When clamping the stainless steel pipe with the existing clamp, it is necessary to use the fingers to apply pressure to the clamp. Long-term clamping will cause finger fatigue, which leads to the stainless steel pipe being clamped in an unstable state due to the weak clamping force during the clamping process, causing the stainless steel pipe to fall and be damaged, which may injure workers or damage surrounding equipment.
