CASE STUDY MediTrac® in Hospital Renovation
Until the innovative new product, Corrugated Medical Tubing (CMT), was adopted into the Health Care Facilities Code NFPA 99 – 2018; installation, retrofits and repairs of medical gas piping systems were confined to the rigid installation practices of hard-drawn seamless copper pipe.
MediTrac, the world’s first flexible medical gas piping system, bends to a facility’s needs, resulting in shorter downtimes. MediTrac decreases installation time by greatly reducing the number of fittings, potential leak points and chance of contamination during installation.
Project Overview: OmegaFlex® the makers of MediTrac® partnered with Acute Medical Gas Services from Goffstown, NH on the first US based BETA site installation at Melrose-Wakefield Hospital in Melrose, Massachusetts. The project included the relocation of an existing zone valve box from the patient care area to a designated area outside of the patient care area as required per NFPA 99.
Installation Overview The new zone valve box, containing shutoffs for both a vacuum and oxygen line, was located on the other side of a corridor beyond the fire stop roughly 65 feet away. For comparison purposes the vacuum line was done in 1-1/4 hard-drawn copper pipe and the oxygen lines were done in 1 MediTrac CMT. All piping runs were done
in parallel taking the same route between connection points. In total approximately 75 of piping was used for each run (150 total per system).
The piping run included a vertical rise out of the new zone valve box followed by a series of 90° and 45° bends to the 65 straight run down the corridor. The piping then turned 90 degrees across the corridor and was tied into the existing supply and distribution lines. Both piping systems utilized the same existing hanger supports down the 65’ corridor run.
Summary of Piping System Connections Medical Vacuum Brazed Hard-drawn copper pipe details: 2 runs total • 150 of hard - drawn K copper pipe • 28 fittings with a total of 56 brazed joints
- 12 – 90° elbows - 4 – 45° elbows - 12 couplings
Medical Oxygen MediTrac® CMT details: 2 runs total
• 150 of MediTrac® CMT • 8 fittings total with 4 brazed joints
- 4 MediTrac® CMT fittings - 2 couplings - 2 axial swaged hard-drawn copper pipe connections

Termination of MediTrac CMT piping is easy with the patent pending MediTrac fitting.
MediTrac cuts the same as hard-drawn copper pipe but navigates confined spaces and corners without the hot-work.
As with all rigid piping installations elbows are required when turning corners and changing direction to route around, above, or below obstacles. MediTrac CMT is able to bend around corners and flex to avoid potential obstacles. Resulting in no intermediate connections.
In this case two 1 MediTrac CMT lines were pulled together, much like pulling wire or cabling through a hole in the fire wall down the entire length of the corridor in roughly 15 minutes. An additional 30 minutes later the piping rough in was complete and ready for fitting connections.
Labor Man Hours per System Overview of man hours and comments received from Acute Medical Gas Services
Medical Vacuum Brazed Hard-drawn copper pipe details
• 64 total man hours to tie in the new valve box and prepare for the final tie in to existing line.
Medical Oxygen MediTrac® CMT details • 12 total man hours to pull and connect,
- Note: Prefab of a T for an alarm sensor and reducing couplings to make the final tie-in required. So, in theory, you could subtract several hours from this time.
Overall the use of MediTrac® resulted in a 79% reduction in joints for the piping system and a minimum of an 82% reduction in labor man hours. Additional benefits of the MediTrac® system as noted by Acute Medical include:
Ease of transport to the job site
Reduced cost in support items such as brazing rods and purge gas
Contamination possibility is greatly reduced
Lack of intermediate joints and the systems flexibility resolve fire prevention during difficult brazing situations unlike hard drawn copper systems (wire, ducts with dust inside, walls, gas piping, etc.)

MediTrac® by OmegaFlex® continues its introduction into the market by providing innovation from end to end with another installation.
Project Overview OmegaFlex® the makers of MediTrac® partnered with Pure-Line Plumbing from Durham, NC on a medical vacuum system retrofit at Henrico Doctors’ Hospital in Henrico, Virginia. The project included the removal of an existing oxygen only zone valve box and installation of a new O2 and vacuum zone valve box. This newly added box is used to service 9 patient care rooms with updated oxygen outlets and newly added vacuum outlets. Existing oxygen piping was reused and a hybrid system utilizing copper pipe and MediTrac® corrugated medical tubing was installed for the vacuum lines. This hybrid system installation highlights the easy and efficiency of using MediTrac® CMT seamlessly with traditional rigid copper tubing materials.
Installation Overview The tie in to the closest vacuum line was approximately 110 away from the updated
zone valve box. 1 MediTrac® was used to navigate multiple changes in direction in a tightly packed space above the ceiling with 2 through wall penetrations. Routing of rigid copper piping in this location would have been difficult due to the limited space available for routing of the piping system and the brazing that would have been required for the traditional piping system.
The outlet from the zone valve box was connected to roughly 28 of 3/4 MediTrac® CMT. Piping was installed vertically up the wall cavity to the space above the drop ceiling and routed into the patient care area via a 3rd through penetration. At this point the piping system was transitioned from MediTrac® to rigid copper pipe that was routed in an “L” configuration in the ceiling of the corridor outside of the individual patient care rooms. A total of six (6) brazed copper tees were installed to provide seven (7) drops off the copper piping to service all nine (9) patient care rooms.
In total there was roughly 110 of 1 and 185 of ¾ MediTrac® CMT installed in this project in conjunction with approximately 68 of ¾ rigid brazed copper. (continued

1" MediTrac ® CMT connection to zone valve box for vacuum.
3/4" MediTrac ® CMT drop to patient care room from rigid copper main.
Installation Highlights The initial 110 run from the existing vacuum line to the new zone valve box was pulled and roughed in in 40 minutes. That time included the drilling of 2 through penetrations. Final tie in took the total install time of this section to roughly 1 hour. It was estimated that to complete this same run with rigid copper piping would have taken at least 4.5 hours and required a large number of braze joints to navigate the tight installation location.
While most of the tie-ins from the copper line to the patient care rooms were not very long, ranging from 15 to 35, the reduction of overhead work to fit and braze copper ells and couplings saved on installation time. That savings on installation time allowed the job to be completed in the short window available for the installation.
• Overall, this project went from days to hours for completion
• Contamination possibility was greatly reduced
• There was a significant reduction in intermediate joints
• The hospital was able to return to service and back to providing patient care in a short amount of time
