1. Design and Planning
Pipeline Sizing: Designed to meet the specific gas flow requirements of the facility.
Material: Typically, copper pipes (Type L or K) are used for medical gas pipelines.
Compliance: Adheres to international standards like NFPA 99 (National Fire Protection Association), HTM 02-01, and other relevant ISO standards.
Layouts and Blueprints: Detailed design drawings for medical gas pipelines are prepared in advance, showing location, dimensions, and sizing.
2. Components for Installation
Medical Gas Outlets: Specific outlets per gas type (Oxygen, Nitrous Oxide, Medical Air, Vacuum, etc.).
o MAP Company outlets typically feature color-coded and key-coded designs for safety and easy identification.
Zonel Valves: Enables isolation of specific zones or sections in emergencies.
o Designed for easy access, usually installed at prominent, accessible points.
Alarm Systems: Monitors pipeline pressure and alerts for any irregularities.
Manifold Systems: Controls gas supply and ensures uninterrupted delivery.
Control Panels: Centralized control over multiple gases for ease of operation.
Pressure Regulators and Gauges: Ensures the gas is supplied at consistent, regulated pressure.
3. Installation Process
Piping: Pipes are brazed using high-quality filler metals to prevent leaks and corrosion.
Purging: The system is purged using Nitrogen to prevent contamination and oxidation during brazing.
Labeling: Gas lines are color-coded and labeled per gas type along their length.
Connections: Flanged, quick-connect, or threaded connections as per design.
4. Testing Procedures
Pressure Testing: Tests for leakages by pressurizing the system with an inert gas (often Nitrogen).
o Pressure Levels: Typically 1.5 times the working pressure.
Leak Testing: Vacuum is applied to the system and checked for any pressure drop over a set period.
Purity Testing: Ensures that the pipeline is free from contaminants before first use.
5. Commissioning and Documentation
Flow and Pressure Verification: Confirm that gases flow at the required pressure and volume to all outlets.
System Documentation: Includes blueprints, certificates of compliance, inspection reports, and test results.
Staff Training: Instruct medical staff on the usage and emergency protocols associated with the gas pipeline system.
