Buttweld Stub End Pipe is designed to change the direction of the flow of fluids or gases. It is usually made by cutting and bending a straight length of pipe. The two ends of the pipe are then welded together to form the bend. This type of pipe is commonly used in plumbing, piping, and other mechanical installations where changing the direction of fluid flow is necessary. Buttweld Stub End Pipe is basically made from materials such as stainless steel, carbon steel, and nickel alloys.
