Reduced Hdpe coupling
The reduced Hdpe coupling is irrigation equipment used in major irrigation equipment. It is commonly use in connecting Hdpe pipes of different sizes.
It has a pressure nominal (PN) of 16 to pressure nominal of 25. The pressure nominal (PN) is the working pressures of the materials and it also identifies the strength of the material. The larger the pressure nominal number, the stronger the material.
Currently, most reduced Hdpe coupling is made of plastics (polymers). This type of material reduces the effects of corrosion. Corrosion may compromise the water quality which is an essential factor in irrigation. Reduced sockets are mostly determined by their nominal diameter (inside diameter).
Nominal sizes may range from 20 millimeters to 91 millimeters as the commonly used plastic reduced couplings in irrigation fields.
Function of the plastic reduced socket
The main function of the plastic reduced Hdpe coupling is to increase the pressure by reducing the surface area of the piping system. However, by doing this, the pressure is built-up within a constricted surface area. This, therefore, generates dynamic pressure (Pushing effect) inside the pipe. Pressure helps by pushing water with a higher velocity.
The reduced coupling is characterized by toughness, ductility and they provide a sound
joint able to withstand pipeline expansion and contraction and other stresses though this may not be the only method to reduce stress, it’s among the most effective.
The plastic reduced couplings are usually accompanied with the threads, O rings, grippers to give it strength this is because it has to be compatible with other irrigation components.
Parts of the reduced Hdpe coupling
In conclusion, the best way to select the best plastic reduced coupling is first to know your water driving force. This force also is known as pressure may be either a water pump or natural gravity depending on the general slope of the land.
The water driving force will ensure that the right reduced plastic PN is selected and incorporated with other equipment that is used for irrigation hence delivering high efficiency.
