Industrial Piping Glossary

A pneumatic device that converts compressed air into mechanical motion (linear or rotary). Commonly used in the Oil & Gas sector to open or close valves.

A pressure vessel used to store compressed air. It helps balance the demand from the plant and prevents the compressor from "cycling" (turning on and off) too frequently.

International engineering codes that set the standards for "Process Piping" (B31.3) and "Hydrogen Piping" (B31.12).

A metric unit of pressure. 1 Bar = 14.5 PSI. Standard industrial systems in the UAE typically operate at 7 to 10 Bar.

A measurement of the volume of air flow. While Bar/PSI measures "strength," CFM measures "quantity."

A section of piping that is closed off and has no airflow. These are dangerous in Food and Pharma industries as they can trap moisture and grow bacteria.

A high-end air dryer that uses chemical beads (activated alumina) to absorb moisture. It can reach a Dew Point of -40°C, essential for "instrument-grade" air.

The temperature at which water vapor in the air begins to condense into liquid water. A lower dew point means "drier" air.

A high-security tube fitting used in high-pressure and hydrogen lines to ensure a leak-proof, vibration-resistant seal.

A three-part unit installed at the "point of use" to clean the air, set the pressure, and add a mist of oil for tool lubrication.

Steel coated with a layer of zinc to prevent rust. Widely used in the UAE construction sector for its durability and cost-effectiveness.

The primary, large-diameter pipe that carries air from the compressor room throughout the facility.

A technical phenomenon where hydrogen molecules enter a metal's structure, making it brittle and prone to cracking. Prevented by using high-quality 316L Stainless Steel.

High-purity compressed air (clean, oil-free, and dry) used to power sensitive control instruments in refineries.

The percentage of compressed air lost through holes or loose joints. A typical unmanaged factory loses 20% to 30% of its air to leaks.

A modern piping system using lightweight aluminum pipes and push-to-connect fittings. It is 100% corrosion-resistant and easy to modify.

A certification (ISO 8573-1) stating that the air contains zero oil vapor. Mandatory for the Pharmaceutical and Food & Beverage sectors.

A specialized, automated welding process used for Stainless Steel pipes to ensure a perfectly smooth, hygienic internal seam.

Any system or tool that operates using pressurized air or gas.

The loss of air pressure as it travels through a pipe due to friction. Large pipes and "Ring Main" designs minimize this loss.

A piping layout where the main header forms a complete circle. This allows air to flow from two directions to any point, maintaining equal pressure.

A measurement of a pipe's wall thickness. Higher "Schedule" numbers (like Sch 80) can handle significantly higher pressures.

A high-grade, low-carbon steel used in corrosive or hygienic environments (Food, Pharma, Hydrogen).

A method of finding air leaks by "listening" for the high-frequency sound they make, which is inaudible to the human ear.

An automatic valve that removes water (condensate) from the air lines without wasting any compressed air.
