Types of Gas Piping & Distribution Systems

Gas piping & distribution systems are available in a variety of configurations to meet the specific needs of different laboratories. The choice of system depends on factors such as the types of gases used, the gas consumption rates, the pressure requirements, and the budget. Some common types of gas piping & distribution systems include:

• Centralized Gas Distribution Systems: Centralized systems are typically used in large laboratories with high gas demand. These systems involve a central gas source, such as a bulk tank or a bank of cylinders, from which gas is distributed to various points of use throughout the laboratory. Centralized systems offer advantages such as centralized control, efficient gas management, and reduced maintenance costs.
• Decentralized Gas Distribution Systems: Decentralized systems are often used in smaller laboratories or for specific applications where a central gas source is not feasible. These systems involve individual gas cylinders or small gas generators that are located near the point of use. Decentralized systems offer flexibility and ease of installation but may require more frequent cylinder changes or generator maintenance.
• Manifold Systems: Manifold systems are used to distribute gases from multiple sources to multiple points of use. These systems typically involve a manifold, which is a device that combines multiple gas lines into a single outlet. Manifold systems offer flexibility and redundancy, allowing for the use of multiple gas sources and the ability to switch between sources if one fails.
• Gas Panel Systems: Gas panel systems are pre-engineered systems that provide a comprehensive solution for gas distribution in laboratories. These systems typically include a gas panel, which is a cabinet that houses gas regulators, valves, and other components for controlling and distributing gases. Gas panel systems offer convenience, safety, and ease of installation.

Materials Used in Gas Piping & Distribution Systems

The materials used in gas piping & distribution systems are critical to ensuring the safety, reliability, and longevity of the system. The choice of materials depends on the types of gases used, the pressure and temperature requirements, and the environmental conditions.
