Key Concepts and Principles

Types of Materials Used in Internal Water Supply System

There are several types of materials used in the internal water supply system. Let's explore some of the commonly used materials:

1. Pipes

Pipes are the primary components of the internal water supply system. They are responsible for carrying water from the source to different parts of the building. The following are the commonly used types of pipes:

• Copper pipes: Copper pipes are known for their durability, corrosion resistance, and heat conductivity. They are commonly used in residential and commercial buildings.

• Galvanized iron pipes: Galvanized iron pipes are coated with a layer of zinc to prevent corrosion. They are commonly used in older buildings but have been replaced by other materials due to their tendency to rust and clog over time.

• Polyvinyl chloride (PVC) pipes: PVC pipes are lightweight, easy to install, and cost-effective. They are resistant to corrosion and provide a smooth flow of water. PVC pipes are commonly used in residential and commercial buildings.

• Cross-linked polyethylene (PEX) pipes: PEX pipes are flexible, durable, and resistant to corrosion. They are commonly used in modern plumbing systems due to their ease of installation and compatibility with different water qualities.

1. Fittings and Connectors

Fittings and connectors are used to join pipes and redirect the flow of water. The following are some commonly used fittings and connectors:

• Elbows: Elbows are used to change the direction of the pipe. They are available in different angles, such as 45 degrees and 90 degrees.

• Tees: Tees are used to create a branch in the pipe, allowing water to flow in multiple directions.

• Couplings: Couplings are used to join two pipes of the same diameter.

• Valves: Valves are used to control the flow of water. They can be manually operated or automated.

1. Water Storage Tanks

Water storage tanks are used to store water for future use. The following are some commonly used types of water storage tanks:

• Concrete tanks: Concrete tanks are durable and can withstand high water pressures. They are commonly used in large buildings and industrial applications.

• Steel tanks: Steel tanks are strong and resistant to corrosion. They are commonly used in residential and commercial buildings.

• Fiberglass tanks: Fiberglass tanks are lightweight, corrosion-resistant, and easy to install. They are commonly used in residential buildings.

Factors to Consider When Selecting Materials

When selecting materials for the internal water supply system, several factors need to be considered:

1. Durability and Lifespan

The materials should be durable and have a long lifespan to minimize the need for frequent replacements and repairs.

1. Corrosion Resistance

The materials should be resistant to corrosion to ensure the longevity of the system and maintain water quality.

1. Cost-effectiveness

The materials should be cost-effective, taking into account the initial cost, installation cost, and maintenance cost.

1. Ease of Installation and Maintenance

The materials should be easy to install and maintain, reducing the overall time and effort required.

1. Compatibility with Water Quality and Pressure

The materials should be compatible with the water quality and pressure in the area to ensure optimal performance.

1. Fire Resistance and Safety Standards

The materials should meet fire resistance and safety standards to minimize the risk of fire and ensure the safety of the occupants.

Typical Problems and Solutions

Leaks and Pipe Bursts

One of the common problems in the internal water supply system is leaks and pipe bursts. These issues can lead to water wastage, property damage, and disruption of water supply. The following are the causes of leaks and pipe bursts:

1. Causes of Leaks and Pipe Bursts

• Corrosion: Corrosion can weaken the pipes over time, leading to leaks and pipe bursts.

• High Water Pressure: Excessive water pressure can put stress on the pipes, causing them to burst.

• Freezing Temperatures: Freezing temperatures can cause the water inside the pipes to expand, leading to pipe bursts.

1. Solutions and Preventive Measures

• Regular Inspection: Regular inspection of the pipes can help identify any signs of corrosion or damage.

• Pressure Regulation: Installing pressure regulators can help maintain the water pressure within the recommended range.

• Insulation: Insulating the pipes in areas prone to freezing temperatures can prevent pipe bursts.

Corrosion and Scaling

Corrosion and scaling are common issues in the internal water supply system. Corrosion refers to the deterioration of the pipes due to chemical reactions, while scaling refers to the buildup of mineral deposits inside the pipes. The following are the types of corrosion and scaling:

1. Types of Corrosion and Scaling

• Uniform Corrosion: Uniform corrosion occurs evenly across the surface of the pipe.

• Pitting Corrosion: Pitting corrosion refers to the localized corrosion that creates small pits on the pipe surface.

• Galvanic Corrosion: Galvanic corrosion occurs when two different metals come into contact, causing one metal to corrode.

• Internal Scaling: Internal scaling refers to the buildup of mineral deposits inside the pipes, reducing the flow of water.

1. Methods to Prevent and Control Corrosion and Scaling

• Cathodic Protection: Cathodic protection involves the use of sacrificial anodes or impressed current to protect the pipes from corrosion.

• Water Treatment: Water treatment methods, such as filtration and chemical treatment, can help control scaling by removing minerals from the water.
