Types and connection methods of elbows

Elbows are fittings that change the direction of pipelines and are common in piping systems. Here are different aspects to introduce to you:
Common types
Divided by angle: there are 45 °, 90 °, and 180 °, etc. The 45 ° elbow is used for smaller angle turns, the 90 ° elbow is used to change the vertical direction, and the 180 ° elbow makes the pipeline turn back.
Classified by material: there are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals, and plastics.
According to the production method, it can be divided into pushing, pressing, forging, casting, etc.
major role
Change direction: This is its basic function, which allows the pipeline to change direction according to demand.
Connection device: used to connect pipelines and equipment in different directions or positions to ensure normal fluid transport.

Application scenarios
In the field of architecture, it is widely used in water supply and drainage, heating, gas and other systems to ensure the normal operation of the system.
Industrial sector: chemical, petroleum, power and other industries, transporting various media and adapting to complex process flows.

Connection method
Welding: By heating or applying pressure, or a combination of both, the welded part is made to achieve atomic bonding. It is commonly used in industrial pipelines, with strong connections and good sealing properties.
Flange connection: using flanges, gaskets, and bolts for easy installation and disassembly, suitable for parts that require frequent maintenance.
Threaded connection: suitable for small-diameter pipelines, easy to operate, but relatively poor sealing performance
