Description
Sand packer (pipe bender) is a specialized technician who fills the inside of pipes used in buildings and equipment piping with sand or dedicated jigs, and forms precise angles and curves using manual or hydraulic pipe benders. Before work, measures dimensions and angles, cuts and deburrs the pipe, fills it with internal packing material, and performs bending. After bending, removes the packing material, cleans, and makes finishing adjustments. Requires high attention to detail, mechanical operation skills, and on-site safety management.
