The construction process that should be completed when installing the stainless steel electric ball valve Wujiang stainless steel electric ball valve series products are metal products, which have high tensile and compressive strength, excellent soft sealing performance, convenient loading and unloading and other functions, and are often used in power and metallurgy. Recently, we received a letter from the consumer asking about the installation of stainless steel electric ball valve, and Dongfeng experts gave a detailed answer. The stainless steel electric ball valve is made of stainless steel, which is of high value. It should be carefully installed to avoid unnecessary losses. Let Dongfeng experts talk about the construction process that should be completed when installing the stainless steel electric ball valve.
1. Relevant processes that should be completed before the installation of stainless steel electric ball valve, such as flaw detection, heat treatment, pressure test, cleaning, degreasing, internal corrosion prevention and lining, have been completed and meet the requirements;
2. The civil works related to the stainless steel electric ball valve have been completed and passed the joint inspection of relevant personnel of the civil engineering and installation unit. During the inspection, the pipe support foundation, pipe bridge, pipe pier, pipe trench, cushion, valve well, as well as the embedded parts, reserved holes, waterproof shoulders, etc. used for the electric ball valve shall be checked according to the drawings, and must meet the design requirements and installation requirements. Both civil engineering and installation parties shall countersign for approval; 3. The inside of pipes, pipe sections, pipe fittings, valves, etc. has been reasonably clean, and no dirt or sundries are left;
4. The pipes, stainless steel electric ball valves, valves, gaskets, etc. have been checked according to the design requirements, and their materials, specifications and models are correct; The prefabrication quality of electric ball valve meets the requirements;
5. Pipes, pipe fittings and valves have passed the inspection and have the required technical certificates;
6. Check the position and quantity of the guard plates used for installing or welding the supports and hangers of the electric ball valve on the equipment to meet the requirements for the installation of the electric ball valve of the stainless steel electric ball valve.
7. The equipment connected by the stainless steel electric ball valve is aligned and qualified, fixed, the secondary grouting meets the requirements, and the notice of piping permission is obtained.
