From sterile cleanrooms to complex medical gas systems, ACCO combines engineering excellence with local regulatory compliance to deliver state-of-the-art clinical facilities.

Engineering Safe and Reliable Medical Gas Networks

A Medical Gas Pipeline System (MGPS) is one of the most critical life-support networks in any modern healthcare facility. It delivers essential gases—such as Oxygen (O2), Nitrous Oxide (N2O), Medical Air (4 Bar) for respiratory therapies, Surgical Air (7 Bar) for pneumatic tools, and Vacuum for suction—directly to patient bedheads, emergency departments, intensive care units (ICUs), and operating theaters. Because patients’ lives depend on the uninterrupted delivery of high-purity gases, the design, installation, and commissioning of MGPS must adhere to stringent global standards, specifically HTM 02-01 (Health Technical Memorandum) and NFPA 99.

Substandard materials, joint leaks, or cross-connections in medical gas pipelines are catastrophic safety hazards. As turnkey experts, ACCO designs and installs certified MGPS networks across Pakistan, ensuring strict safety controls from the manifold room to the patient outlet.

Technical Engineering Specifications & Components

An HTM 02-01 compliant Medical Gas Pipeline System consists of several specialized components engineered for reliability:

• Medical Grade Copper Piping: Only seamless, degreased medical-grade copper pipes conforming to ASTM B819 or EN 13348 must be used. These pipes are specially cleaned to ensure they contain no hydrocarbons, which could cause spontaneous combustion when exposed to high-pressure oxygen.
• Brazing with Nitrogen Purging: During installation, copper joints must be brazed using silver-copper phosphorus alloy rods (minimum 5% silver content). Crucially, a continuous purge of oxygen-free nitrogen gas must flow through the pipe during brazing to prevent the formation of copper oxide scale inside the pipe.
• Manifold Rooms & Storage: The source system must include a primary supply source, a secondary backup manifold, and a reserve manifold. Automatic manifold changeover control panels must manage the switch between cylinders seamlessly when pressure drops.
• Area Valve Service Units (AVSUs) & Alarms: AVSUs are installed at the entrance of every clinical ward and operating theater. They act as shut-off valves for emergencies and maintenance. Local alarm panels monitor pipeline pressure and alert clinical staff of high or low pressure via audio-visual signals.
• Pressure Testing & Commissioning: The entire network must undergo rigorous testing. First, a leakage test at 1.5 times the working pressure using dry nitrogen is held for 24 hours. Next, cross-connection tests are executed to verify that no gas line is cross-connected (e.g., Oxygen outlet delivering Nitrous Oxide). Lastly, particulate and moisture testing is conducted before gas charging.

Pakistani Market & PHC Regulatory Compliance

The Punjab Healthcare Commission (PHC) mandates that all surgical facilities and intensive care units possess dual backup sources for medical oxygen. Under local regulations, a hospital must have a primary oxygen source (e.g., a manifold or PSA generator plant) plus a secondary manifold, and a reserve supply of portable oxygen cylinders located directly in the clinical area. Sourcing medical-grade copper pipes and fittings in Pakistan requires careful validation, as local markets are flooded with commercial-grade plumbing pipes that contain oil residues.

The cost of installing a certified MGPS network in Pakistan typically ranges from PKR 180,000 to PKR 300,000 per bed. This cost varies based on the distance from the manifold room, the number of clinical outlets per bed, and the inclusion of medical air compressors and vacuum pump stations. ACCO imports premium, certified degreased copper pipes and gas outlets, ensuring fully compliant systems that pass PHC licensing inspections without issues.
