Study Notes
Cast Iron Pipe
- Most favored material for drainage systems due to its durability.
- Suitable for buildings up to 25 stories; above this height, constant vibrations may lead to leaks at joints.
- Prone to corrosion over time.
Acid Resistant Cast Iron Pipe
- Comprised of a blend of cast iron and silicon, enhancing its durability against acidic environments.
- Commonly utilized in chemical laboratories and industries discharging acidic waste.
- Brittle in nature, necessitating stronger support structures.
Asbestos Pipe
- Constructed from asbestos fibers mixed with Portland cement.
- Thickness is double that of standard cast iron pipes, offering enhanced sturdiness.
- Applied for soil, waste, ventilation, and downspout systems; excels in underground embedment.
Bituminous Fiber Sewer Pipe
- The most economical option among pipe materials.
- Lightweight and slightly flexible, allowing for easier handling and installation.
- Vulnerable to damage from excessive hot water or chemical exposure, which can soften the material.
Vitrified Clay Pipe
- Fabricated from clay, molded into lengths of 75 cm, and glazed for added durability.
- Heated at temperatures up to 1370 degrees Celsius for strength and acid resistance.
- Highly durable, making it ideal for underground applications like public sewers and storm drains.
Lead Pipe
- Represents one of the oldest types of plumbing materials, historically used by ancient Egyptians, Greeks, and Romans.
- Highly resistant to acid, suitable for underground installations; however, its use is generally discouraged today due to health concerns.
Galvanized Steel Pipe
- Made from mild steel, but suffers from susceptibility to corrosion when exposed to alkaline and acidic water.
- Its longevity decreases when utilized as a hot water supply line due to accelerated deterioration.
Galvanized Wrought Iron Pipe
- Offers superior quality compared to standard galvanized steel pipes.
- More resistant to acidic waste, making it a better option for plumbing installations.
Brass Pipe
- One of the more expensive materials, composed of approximately 15% zinc and 85% copper.
- Notable for its smooth interior surface and high resistance to acids, positioning it as a top choice for waste and water supply systems.
Copper Pipe
- Known for its durability and exceptional resistance to corrosion.
- Simplifies installation processes due to its manageable weight.
- Features a smooth interior surface which aids in optimum fluid flow.
Pipe Classification
- K type: Heaviest variant, recommended for underground use where additional strength is needed.
- L type: Lighter option available in both rigid and flexible forms for versatile applications.
- M type: Thinnest profile available only as a rigid form, suitable for small water supply lines and radiant heating setups.
