Pipefitting techniques involve the installation, maintenance, and repair of piping systems used in various industries. These techniques include measuring, cutting, and joining pipes made from materials like PVC, copper, or steel. Proper alignment and support are crucial to ensure the system functions effectively and safely. Common methods used in pipefitting include welding, soldering, and using mechanical fittings. Welded joints provide strong connections, while soldering is often used for copper pipes. Mechanical fittings, such as flanges and couplings, allow for easier assembly and disassembly, making maintenance more efficient.
