Study Notes
Plumbing Pipes
- Cast iron pipe is durable and commonly used for drainage systems in buildings less than 25 stories high.
- Cast iron pipes are susceptible to corrosion from gases like carbon dioxide, sulfur oxide, and methane.
- Clay pipes are highly resistant to most acid waste and are commonly used for underground installations like sewers.
- Lead pipes are resistant to acid and suitable for underground installation but should not be used for water intended for human consumption due to their poisonous nature.
- Galvanized steel pipes are easily corroded by alkaline and acid water and deteriorate faster when used as hot water supply lines.
- Galvanized wrought iron pipes are more resistant to acid waste compared to galvanized steel pipes.
- Brass pipes are expensive but offer smooth interior surfaces and high resistance to acid, making them ideal for waste and water supply installations.
- Copper pipes are durable, corrosion-resistant, and easy to install. They are commonly used for water supply lines and radiant heating installations.
- Copper pipes come in three types: K, L, and M, each with different wall thicknesses and applications.
- Stainless steel pipes are known for their high strength, resistance to corrosion, heat, and chemical damage, making them ideal for drinking water systems.
- Plastic pipes have gained widespread acceptance as sewer and cold water pipes, offering advantages like resistance to rust, corrosion, and scale buildup.
- Plastic pipes come in rigid and flexible types, with various subcategories depending on the material used.
- Some plastic pipes, such as CPVC, PVDC, and PPR, are considered suitable for hot water lines, but their long-term performance at high temperatures requires further research.
- Plastic pipes offer numerous advantages over metal pipes, including ease of installation, flexibility, and lighter weight.
Pipe Fittings
- PVC pipe fittings for cold water lines include couplings, adapters, plugs, caps, elbows, tees, and union patentes.
- PPR pipe fittings for cold water lines include couplings, adapters, plugs, elbows, tees, union patentes, and bridge elbows.
- PVC pipe fittings for DWV (drain, waste, and vent) or storm lines include elbows, end caps, couplings, single or double wye fittings, and p-traps.
