Hydraulic Pipe Bending Machine

The process of pipe bending finds its importance in many industries, instruments, fluids transportation etc. The aim of this research is to design and fabricate a hydraulic jack-based pipe bending machine which has ability to bend pipes used at gas supply industry, while keeping in mind the requirements of a good pipe bending machine to provide high quality bends without defects but at the cost lesser than the existing pipe bending machines available in the marketplace. The fabricated pipe bending machine works on the principle of press bending method to perform the bending operation. The design of the proposed pipe bending machine is based on essential parameters of bending process such as radius and angle of the bend, diameter and thickness of the pipe. The single acting hydraulic jack of 16000 KG load capacity is used to apply the required pressing force to bend a circular pipe having the outer diameter ranging from ½ inch to 2 inches.
