Pipe Bends

135 degree bends, or 45 degree bends as they are sometimes called, are used to create a change of direction in a waste pipe system. Two bends are often used together to create an offset in the pipe run. Knuckle bends are used to create tight, neat 90 degree bends in a waste pipe system. They have a tighter radius than the standard swept bends. Swept bends are used to create a 92.5 degree change of direction in a waste pipe system. They have a longer radius than knuckle bends and the 92.5 degree angle promotes a self-cleansing flow. To make a solvent weld joint, first ensure that the outer wall of the pipe and the inner wall of the fitting are both clean and free from grit or swarf. Apply SC250 solvent cement to both surfaces. Push the pipe fully into the fitting and give it a twist to ensure that full contact has been made. Clean off any excess solvent with a damp cloth and leave for 5 minutes to set. The installation should be left for 12 hours before testing. Solvent weld joints are permanent – they cannot be demounted once the joint has been made. When using solvent cement, always work in a well ventilated area and keep the cement away from heat sources or naked flames. Avoid any contact with skin – if contact does occur then wash thoroughly with soap and water.
