In life, ductile iron pipe fittings are used as water pipes and play a very good role. It has good corrosion resistance, long service life, hygiene, and will not pollute the environment. When installing, it should be installed according to the process flow .One is the trench excavation operation. Preparations should be made before excavation. Before trenching, carefully understand the geological conditions, take active reinforcement and protection measures, and carry out construction according to the installation drawings. Its specifications and The depth has certain regulations, scientific regulations, and must be constructed in accordance with the regulations. During operation, there are many excavation methods. Generally, mechanical excavation is used, and manual bottom cleaning is required. Industrial chiller manufacturers tell you the overall process The second is to lower the pipe. After cleaning, the pipe can be started. The direction of the socket is consistent with the installation direction of the pipe. The third is to clean the socket to avoid the adhesion of the water. The above is the construction of ductile iron Methods and procedures for pipe fittings.
