An integral part of people’s life can be safely called pipelines for various purposes. On systems of pipelines, heating, water supply systems and other important communications are based on. Installation of pipeline fittings (regulatory and shut -off), as well as its fastening to the pipeline, is carried out using flange joints. Note that the steel flange is the main element of this connection. It is used to join the reinforcement to different pipelines, joining pipelines to different equipment and joints of pipelines.
Currently, flanges are made from materials such as: alloys, polymers, steel, plastic, but steel flanges are most popular. They have a large area of use, for example, they are widely used in industry, where pipelines for various purposes are used. This area is the most responsible and significant for steel flanges.
Flange compounds are used to ensure reliability and tightness of the structure. In addition, they contribute to a simple and quick disassembly of assembly. Steel flanges have a number of advantages, namely:
– the possibility of their use for reinforcement from various materials;
– installation on pipelines of any diameters;
– the possibility of multiple use;
– Applicability of different gaskets.
The disadvantages of such flanges include the fact that they have low tightness of the connection when exposed to certain temperatures and power influences. Despite this, the steel flange is the main element of the pipeline, the manufacturer should understand the degree of importance and observe all the norms, rules in the production process. In practice, production errors can be established, and this can cause material losses. That is why the companies that are engaged in the design of these products must have documents confirming the compliance of GOST flanges.
