What is a Buttweld Collar?
A Buttweld Collar is a type of pipe fitting used to connect two pipes of different sizes in a piping system. It serves as a coupling device, allowing for a secure and leak-proof joint between the pipes. The collar is welded onto the end of one pipe and then connected to the end of another pipe of a different size, providing a transition point between the two. This component is commonly used in various industrial applications to accommodate piping systems with different diameters, ensuring efficient fluid flow while maintaining structural integrity.
