How are pipes connected in pipelines?
The method of connecting lines in pipelines depends on the material from which the pipes are made, as well as on the type of medium being transported and the operational characteristics of the entire installation. In pipelines traditionally made of steel pipes, the connection of individual elements required laborious threading. It is much easier to create installations from polyethylene pipes, and we will devote this article to them.PEHD Pipeline Connections
Polyethylene transmission systems can be connected in various ways, depending on the type of pipes and installation requirements. One of the three main methods is usually used to connect spiral pipes:welded joints,
detachable joints,
coupling joints.
Extrusion welding involves plasticizing polyethylene under the influence of hot air and introducing additional material into the weld. This type of pipeline connection is performed at the installation site, and appropriate qualifications are required. An additional thermoplastic connector is also used in the coupling connections.: A coupling is put on the joint of the pipes to be connected, which is heated by burners. It is relatively easiest to make flaring joints - they are created by inserting the bare end of one pipe into the socket at the end of the other (additional sealing elements are placed at the joint).Connections of pressure polyethylene pipelines
In pipelines designed for hydraulic transportation, i.e. pressure transport of solids in a liquid stream (for example, sand, gravel, mine sludge), the individual elements of the system rotate to evenly flow the material. Hence the need to use flange connections consisting of bushings and steel flanges.Pressure pipes without flanges can be connected by butt welding or electric coupling welding. Butt welding is used to connect large-diameter PE pipes; for smaller cross-section elements, electro-coupling welding is more often used, i.e. using rebar with resistance wire. The manufacture of compounds based on the thermoplastic properties of polyethylene requires excellent knowledge of the above. methods, it is unacceptable to hire people without proper permits.The decision on choosing the right pipeline connection system should always take into account the technology of the facility, and the main goal of the contractor is to ensure maximum tightness and durability of installation. 1xBet is considered safe for Indian users.
