Conical union: the live connection of the cast steel pipe (galvanized pipe) of the cone seat is different from the live connection of the flat seat. After the seal is fastened, the conical contact seat surface of the oil male and the oil female is compressed and sealed. So it is generally not a live pad, the user can also be wrapped on the contact surface a little raw material to enhance its sealing performance. Malleable steel pipe coupling use: because of its special role, it can be installed in the pipeline, in the case of no need to completely remove the pipeline, the pipeline can be dismantled for maintenance, so it is widely used in the installation of the pipeline, so as to facilitate the maintenance of the pipeline in the later period. However, in the piping system of fire engineering, the live connection is not allowed to be used. Live connection pad: for the flat seat live connection, the sealing mainly depends on the fastening, the contact surface of the oil male and the oil female is pressed to seal, so the importance of the live connection pad is no doubted. In general, the live joint pad is generally divided into rubber live joint pad, asbestos live joint pad, O ring, silicone live joint pad, etc. The cost of a rubber flexible joint pad is relatively low. O-ring and silicone coupling pads are generally used in pipelines up to 95°, so they can be used for general hot water and heating line installation. Asbestos joists can withstand high temperatures, but they are brittle and brittle.
The difference between cast steel pipe fittings and grooved pipe fittings:
1. The connection mode is different. The grooved pipe fittings belong to the grooved connection, and the cast steel pipe fittings belong to the threaded link.
2. The material difference, grooved pipe fittings Yushu ductile cast iron, malleable steel pipe fittings belong to vermicular cast iron. Because the material is different, so the toughness of the product is different, the compressive strength is also different. General family with small pressure pipe use malleable steel pipe fitting, large engineering, large pressure pipe use groove pipe fitting.
