Plumbing pvc elbow

Plumbing PVC elbow is a fitting used to connect pipes, which allows the pipes to change direction at the bend. PVC elbows are usually made of rigid PVC or PVC-U pipes and come in a variety of types, including 90-degree elbows, 45-degree elbows, U-elbows, and S-elbows. These elbows play an important role in the piping system, directly affecting the direction of water flow and the smoothness of water flow.

Function

‌90-degree elbows‌ and ‌45-degree elbows‌ are mainly used to change the direction of the pipe, where the 90-degree elbow makes the pipe turn 90 degrees, while the 45-degree elbow makes the pipe turn 45 degrees. These two types of elbows are particularly common in drainage systems, where the 90-degree elbow is mainly used for drainage, while the 45-degree elbow is used to adjust the direction of water flow to avoid the impact caused by a direct vertical fall.

‌U-elbows‌ and ‌S-elbows‌ are more used for water storage and odor isolation. They help prevent odors and harmful gases in sewage pipes from flowing back into the living space by forming a certain water seal.

Common types of plumbing PVC elbows

Plumbing PVC elbows can be divided into two categories according to their curvature radius: one is the long-radius elbow and the other is the short-radius elbow. Long-radius elbows are suitable for changes in the direction of the pipeline, while short-radius elbows are suitable for three-dimensional steering of the pipeline. In addition, according to the needs of the project, there are other special types of elbows, such as concentric reducer elbows, eccentric reducer elbows, etc.

Selection and installation

When selecting a plumbing PVC elbow, the appropriate type and size should be selected according to the actual project needs and design drawings. During the installation process, attention should be paid to following the construction specifications to ensure that the pipeline is firmly connected and has good sealing performance. At the same time, attention should be paid to the support and fixation of the elbow to prevent deformation or damage to the pipeline due to external forces.

Advantages and precautions

The advantages of plumbing PVC elbows are their excellent performance and low maintenance costs.

During the construction process, the following points should also be noted

Avoid direct sunlight exposure to avoid affecting the service life of the elbow

Open flame heating is strictly prohibited to prevent the material from decomposing and producing harmful gases;

During the construction process, heavy objects should be prevented from hitting to avoid damage to the elbow.

Connection method

The connection of plumbing PVC elbow is usually connected with special glue or hot melt connection to ensure the firmness of the connection and the sealing of the system. PVC elbows have the characteristics of high compressive strength and various specifications and are widely used in water supply and drainage systems in residential, commercial, and industrial fields.

Special glue bonding

Evenly apply PVC special glue on the interface of the PVC elbow and pipe, ensure that the interface is clean and free of oil and dust, and then connect the elbow to the pipe. This method is suitable for small-scale connections and is simple to operate, but it is necessary to ensure that the glue is evenly applied to avoid missing or too thick coating

Hot melt connection ‌

Hot melt connection requires professional Welding Machine and operation skills. First, use a cutting tool to cut the PVC pipe and elbow flat to ensure that there are no burrs on the connection surface. Then, use the Welding Machine to heat the pipe end and the elbow connection respectively. When the surfaces of the two reach a molten state, quickly dock and fix them to ensure a firm connection.
