✔️ Polymer sewage fittings
In the past, cast iron and metal pipes were used to direct the sewage of buildings. These pipes had a high price, and besides being tedious to carry and perform, they did not have a good lifespan. In the last half century, PVC or Plica pipes have gradually taken the place of cast iron pipes, and after some time, with the production of various types of plastic pipes and fittings in the sewage sector, i.e. push fit and polyethylene pipes, it can be said that the use of cast iron pipes in the building Zero arrived.
✔️ Metal pipes and fittings
Metal pipes and fittings, other than cast iron, which are used in sewerage, include white galvanized and black steel pipes. Galvanized pipe along with galvanized fittings have been widely used in drinking water piping, which currently have less consumption than in the past, except for special uses in the riser of the building. These pipes are connected by welding and ribbing.
Black steel connections are used in gas piping, firefighting facilities piping and engine room and heating system piping. Black steel fitting pipes are produced in 2 types, seamed and seamless, and are connected by welding. Copper pipes, which are the most expensive type of piping, are currently only used in air conditioner piping in our country. Split is used, but in European and American countries due to the quality and usefulness of copper, hot and cold water piping and heating are also done with these pipes.
✔️ Mineral fittings tube
In some cases, such as engine room chimney pipes and sewage drainage, it is better to use mineral pipes such as cement pipes. The strength and impermeability of building materials have made this type of pipe to be preferred to tin pipes that can be galvanized in many chimneys. Asbestos pipes are also other types of mineral pipes that are rarely used in buildings because they are carcinogenic.
✔️ Pipes and fittings
In order to protect the wires and cables of electrical installations, all kinds of polyamide, PVC and metal pipes and connections are used as sheaths. Electric hose pipes are also made of fireproof PVC. In addition to flame retardant properties, physical resistance and corrosion resistance are required features in building electrical piping.
