Threaded fitting for steel and cast iron pipes
Steel and cast iron pipe fittings have been used for threaded connections of highways and devices since the beginning of the use of a metal pipe to move the working medium, therefore, even in our time, it is all the more difficult to overestimate the importance of these connecting elements. Pipes and fittings have always been the basis of any pipeline, therefore, with the development of technical progress developed technologies and types of steel and cast iron fittings. The price of manufacturing a fitting depends on the materials used, their weight and purpose. A cast-iron fitting is made by casting and installed for branching, turning, pipe transitions to a different diameter, especially in cases where periodic disassembly of connections is necessary. The steel fitting acts more as a welded threaded connector, as well as couplings and locknuts on the spurs, and is produced mainly from a pipe billet on lathes. Most of the hydraulic devices, such as heaters, filters, distributors, automatic and control devices, etc. it is impossible to manufacture and connect to the pipeline without the use of a steel and cast iron fitting.
