Introduction
For the purpose and purpose of the pipe, the most commonly used connection methods for the construction pipe are composite connections, flange connections, welding, groove connections (wire connections), card sleeve connections, pressure connections, thermal solvent connections, etc.
Top 7 Method of Pipeline Connection
1. Connected connection
Combined connection is the use of integrated plumbing. Metal pipes connected to a size less than or equal to 100mm should be connected to the installed pipes. They are widely used for overhead pipes.
Metal-plastic composite pipes are usually connected by wires. Combined steel pipes are connected by wires, and the surface of the hardened layer and exposed fibers damaged during bonding should be treated with anti-corrosion drugs.
2. Flange connection
Flange connector to fix two pipes, plumbing, or equipment to flange plate in sequence, then insert flask gasket between two flange plates and finally tighten two flange plates with bolts. It is tightly packed.
Large diameter pipes connected by flanges. Flange connectors are commonly used on highway connectors, test valves, water meters, pumps, etc.
3. Warming
Welding is suitable for unconnected steel pipes. It is widely used for concealed pipes and pipes of large diameter and is often used in very high-rise buildings. Connecting a copper pipe can receive special assembly or welding when the pipe diameter is smaller than 22mm; socket or sleeve welding should be used.
4. Groove connection (a telephone connection)
Water-based connectors can be used for fire-fighting water, cold water cooling and hot water, water supply, rainwater, and other systems with a diameter greater than or equal to 100mm steel pipes. It has easy operation and does not affect the initial features of the pipe, construction safety, and durability of the system. , Easy maintenance, time management, and more.
5. Card sleeve connection
The connection method where the pipe is firmly pressed into the pipe with a lock nut and the installation of a corded pipe. Place the appropriate wood at the end of the pipe, then insert the appropriate inner core at the end, and use a screw to tighten the needle. The connection of the copper pipes can also be pressed by the installed ferrules. The ferrule joint is not suitable for areas with high temperatures and vibrations.
6. Pressure connection
Stainless steel pipe connecting technology replaces traditional water pipe technology such as wire, welding, and glue connections. It has features to guard water quality and sanitation, strong corrosion-resistance, and long service life. Socket pipe fittings with special sealing rings are going to be installed during construction.
It is connected to a pipe, and the microphone is pressed with a special instrument to play the role of sealing and tying. The construction has the advantages of easy installation, reliable communication, and cost savings.
7. Hot melting
Thermal connections are widely used to connect new pipes and fittings such as PP-R pipes, PB pipes, and PE-RT pipes.
Key points for hot piping installation: After the heating time is reached, immediately remove the pipes and fittings from the heat sink and heat sink, placing them straight and evenly at the marked depth without alternating to form a uniform flange joint.
Hot connections mainly include hot socket connections and hot melting. A hot connection has the advantages of a simple connection, a long service of LifeFree Articles, and not easy to dismantle.
