Drainage pipe elbows are the most used connection pipe fittings in the process of drainage pipe pre-burial. Its main function is to connect the bend of the pipe to change the direction of the drainage pipe. These elbows are used to connect two pipes with the same or different nominal diameters to make the pipes turn at a certain Angle.
Function
1. Change the direction of the pipe: The elbow is a pipe fitting used to change the direction of the pipe in the pipe system. Common angles are 45 degrees, 90 degrees and 180 degrees, which allows the pipe to be flexibly adapted to various layout requirements during installation.
2. Easy to install and connect: The elbow facilitates the installation and connection of the pipe when the pipe changes direction, helps to improve the air resistance of the pipe and ensure smooth water flow.
3. Anti-blocking effect: The design of the elbow helps prevent impurities from accumulating in the pipe and reduce the risk of blockage. For example, a 90-degree elbow can effectively guide the water flow to fall in a vertical direction and reduce the retention and accumulation of impurities at the elbow.
4. Reduce water flow resistance: Appropriate elbow design can reduce the resistance of water flow in the pipe and ensure smooth water flow, especially in gravity flow drainage pipes, the appropriate elbow shape can minimize the impact of water flow.
Drainage pipe elbows material difference
PVC elbow: PVC is a commonly used plastic material with good physical properties and chemical stability, and can resist corrosion in most industrial and residential environments. PVC elbows usually have high hardness, rigidity and allowable stress, strong anti-aging ability, durable, and a lifespan of up to 50 years. In addition, PVC elbows also have good corrosion resistance, relatively low price, easy bonding, self-extinguishing, recyclable, convenient and simple installation, and good sealing.
PE elbow: PE elbow is made of special polyethylene. It is a new type of synthetic polymer material with good thermal stability, heat insulation, and corrosion resistance to a variety of chemicals, which makes it an indispensable material in modern drainage projects. Polyethylene drainage elbows have the advantages of being non-toxic, odorless, and leak-proof, but their price is also higher than PVC.
Difference:PVC elbows are widely used in drainage systems due to their low cost and good physical properties. They are suitable for most industrial and residential environments and can resist corrosion and chemical erosion.
PE elbows are usually used in more demanding occasions due to their higher safety performance and corrosion resistance, providing stronger safety guarantees.
The material of drainage pipe elbows should be selected to meet the requirements of safety, hygiene, and environmental protection. When purchasing, attention should be paid to the quality and practicality of the material to ensure the normal drainage function, and factors such as service life and economy should also be considered.
