How To Buy Elbows For Non-professionals?

Accurate measurement of the diameter of the existing pipe is the key to purchase elbow. You can use calipers, tape measure and other tools to measure, common household water pipe diameter of 20mm (4-point pipe), 25mm (6-point pipe) and so on. Need to pay attention to the measurement of the outer diameter of the pipe, because the inner diameter of the elbow to match, to ensure a tight connection. At the same time, the angle of the bend should be confirmed according to the actual installation requirements. 90° right-angle bends are most commonly used, but where space is limited or a gentle transition is required, 45° mitre bends or other special angle elbows may be more appropriate. In addition, you also need to consider the radius of curvature of the elbow, a larger radius of curvature, although it takes up a lot of space, but can reduce the resistance to media flow.

Plastic elbow, such as PVC, PPR, etc., the price and good corrosion resistance, suitable for cold water transport and low-pressure environments, such as home drainage pipes, general cold water supply piping. However, its high temperature resistance is poor, not for hot water or high temperature medium transport. Metal elbows include galvanised steel, copper, stainless steel, etc., which have high strength and durability, and are preferred for hot water and high pressure environments. For example, stainless steel elbow can work stably in high temperature, highly corrosive media; copper elbow with good thermal conductivity, commonly used in heating systems and hot water pipelines. However, metal elbow price is relatively high, some metal materials such as iron is easy to rust, need to take good protective measures.

Threaded elbows are connected to the pipeline by rotating and tightening, and the sealing tape needs to be wrapped around the threads during installation to enhance the sealing effect and prevent water leakage. This method is suitable for metal piping, solid connection, but the installation process is more complex, requiring certain tools and skills.Socket elbow installation is more simple, directly insert the elbow into the pipeline port, and then use the special glue can be fixed. Commonly used in plastic piping, easy to operate, ordinary home users can easily get started. However, it is necessary to choose a qualified quality of glue, and apply and connect in the correct way to ensure the sealing and firmness of the connection.

There are various types of elbows, there are many, such as 180 deg elbow, 180 degree short radius elbow, short radius 180 return bends and so on, want to know what kind to choose can also consult us.
