Selecting the Water Drainpipe System
When you are planning the design of a new building and construction is underway, one of the most crucial aspects is that of planning for the drainage system. As important as the water supply pipeline, the drainage pipeline takes the wastewater away from the building and ensures hygiene and sanitation for its occupants. Selecting the right drainage pipe can be a time-consuming affair as it is of great importance. Let us look at some of the commonly used drainage pipe materials for buildings: 1. Cast iron: Among the older materials used for water pipe system pipes in drainage systems is cast iron. The greater strength and durability it imparted to the pipe network made it a material of choice but over time, the cast iron pipes tend to rust and corrode. The rust can contaminate the water and make it unsuitable for consumption.
2. Galvanized steel: This is also another material used for drainage pipes which dates to the middle of the century. It is supposed to be free from rust and corrosion, but the durability of the pipes does not enhance its lifetime, which means that they must be replaced much sooner as compared to other pipes.
3. PVC: Polyvinyl chloride or PVC pipes are perhaps the most popular plastic pipes for use as water drainpipe. These pipes are extremely reliable for use in domestic and commercial environments setups as they are long lasting, durable, resistant to rusting and corrosion and have leak-proof joints.
4. HDPE: High density polyethylene or HDPE pipes are also used for drainage applications. Since they can withstand much higher temperature discharges as compared to other non-metallic pipes, they are preferred for water drain pipes. They are often made available in long lengths and joined with compression type joints or electrofusion.
5. PEX: PEX pipes are also a suitable plastic pipe variant for water drainage networks. Made from cross-linked polyethylene, a type of thermoplastic, PEX pipes and fittings are popular for their ability to withstand high water pressure. They are also the perfect blend of rigidity and flexibility which makes them suitable for installation without too many joints.
