The stainless steel exhaust flex bending tube is made of stainless steel. The chemical composition of stainless steel will keep the surface of the elbow from being corroded and rusted for a long time. But we also need to pay attention to the stainless steel exhaust flex bending tube during cleaning and installation. According to the requirements of the workpiece and the surface condition, the stainless steel exhaust flex bending tube is cleaned by alkaline washing, water-soluble cleaning agent, chlorine solvent sandblasting, shot blasting, and other methods. The stainless steel exhaust flex bending tube is cleaned, and the pickling method is generally not used for cleaning. Let's take a look at how to clean and install the stainless steel exhaust flex bending tube? Here are some answers.

Properly cleaning the stainless steel exhaust flex bending tube can not only improve the safety performance but also extend the life cycle of the stainless steel exhaust flex bending tube. The electrode should be kept dry when in use. The calcium-titanium type should be dried at 150°C for 1 hour, and the low-hydrogen type should be dried at 200-250°C for 1 hour (do not repeat the drying, otherwise the coating will easily crack and peel), so as not to increase the carbon content of the weld and affect the quality of the weldment. When the elbow of the stainless steel exhaust flex bending tube is welded, it is repeatedly heated to precipitate carbides, which reduces the corrosion resistance and mechanical properties. The hardenability after welding is large, and cracks are easy to occur. If the same type of electrode is used for welding, preheating above 300°C and slow cooling treatment at about 700°C after welding must be carried out. If the weldment cannot be subjected to post-weld heat treatment, chromium-nickel stainless steel electrodes should be used.
Before installing the stainless steel exhaust flex bending tube, you must carefully check the various standards of the stainless steel exhaust flex bending tube, whether the path meets the usage requirements, eliminate the defects caused by the transportation process, and eliminate the dirt of the stainless steel exhaust flex bending tube, and do a good job Preparation before installation. When installing the stainless steel exhaust flex bending tube, the elbow of the stainless steel exhaust flex bending tube can be directly installed on the pipeline according to the connection method, and the installation is carried out according to the position of use. Pay attention to the tightness to prevent leakage and affect the normal operation of the pipeline.
