Double Flanged Taper Introduction
A double flanged taper is a pipe fitting that is used to connect two pipes of different sizes. It is a type of taper fitting that has flanges on both ends. The flanges allow the fitting to be connected to other pipe fittings or equipment using bolts or welding.
A double flanged taper consists of the following parts:
- Body: The body is the main part of the fitting. It is made of a strong and durable material, such as steel, cast iron, or ductile iron.
- Flanges: The flanges are the circular plates that are welded or bolted to the body. They are typically made of the same material as the body.
- Taper: The taper is the gradual change in diameter between the two ends of the fitting.
Applications
Double flanged tapers are used in a variety of applications, including:
- Water and wastewater treatment: Double flanged tapers are used to connect pipes in water and wastewater treatment plants.
- Chemical and petrochemical plants: Double flanged tapers are used to connect pipes in chemical and petrochemical plants.
- Oil and gas production: Double flanged tapers are used to connect pipes in oil and gas production facilities.
Selection
When selecting a double flanged taper, it is important to consider the following factors:
- Pipe sizes: The fitting must be the same size as the pipes that it will be connecting.
- Flow rate: The fitting must be able to handle the flow rate of the fluid that will be flowing through it.
- Pressure rating: The fitting must be able to withstand the pressure of the fluid that will be flowing through it.
