Plastic Pipe Types Plastic pipe is used for many plumbing, venting, and condensate applications. You should be familiar with the following types. 1. **ABS** is used for water drains, waste, and venting. It can withstand heat to 180°F without pressure. Use a solvent cement to join ABS with ABS; use a transition fitting to join ABS to a metal pipe. ABS is rigid and has good impact strength at low temperatures. 2. **PE** is used for water, gas, and irrigation systems. It can be used for water-supply and sprinkler systems and water source heat pumps. PE is not used with a hot water supply, although it can stand heat with no pressure. It is flexible and has good impact strength at low temperatures. It normally is attached to fittings with two hose clamps. Place the screws of the clamps on opposite sides of the pipe. 3. **PVC** can be used in high-pressure applications at low temperatures. It can be used for water, gas, sewage, certain industrial processes, and in irrigation systems. It is a rigid pipe with a high impact strength. PVC can be joined to PVC fittings with a solvent cement, or it can be threaded and used with a transition fitting for joining to metal pipe. 4. **CPVC** is similar to PVC except that it can be used with temperatures up to 180°F at 100 psig. It is used for both hot and cold-water supplies and is joined to fittings in the same manner as PVC. Joining Procedure 1. Cut the end square with a plastic tubing shear, a hacksaw, or a tube cutter. The tube cutter should have a special wheel for plastic pipe. 2. Deburr the pipe inside and out with a knife or half-round file. 3. Clean the pipe end. Apply primer if required and cement to both the outside of the pipe and the inside of the fitting. (One-step primer/cement products are available for some applications. Follow instructions on primer and cement containers.) 4. Insert the pipe all the way into the fitting. Turn approximately one-quarter turn to spread the cement and allow it to set (dry) for about 1 min. A close-up of a person\'s hands holding a pipe Description automatically generated
