Looking to streamline your next medical gas installation? Corrugated Metal Tubing (CMT) can cut labor time, reduce the number of brazed joints, and simplify work in tight, hard-to-access areas. Whether you’re dealing with new builds or complex retrofits, CMT gives you flexibility without sacrificing performance—making it a smart choice for today’s fast-paced healthcare projects.

The Savings Don’t Stop at Installation

The savings don’t stop at installation. With fewer connections and quicker routing, CMT helps lower long-term maintenance risks. While rigid copper and stainless systems still dominate critical applications, many clients are switching to CMT for low-pressure and non-critical zones, where speed and flexibility matter most.

Corrugated Metal Tubing was accepted in NFPA 99 code in 2018 and may be an efficient, cost saving solution to complex piping projects in healthcare facilities.

Evaluating Corrugated Metal Tubing for Medical Gas Installations:

Corrugated Metal Tubing (CMT) offers notable advantages in medical gas system design, particularly in retrofit or confined-space applications. Its flexibility allows for fewer directional fittings, minimizing potential leak points and improving flow efficiency. Installation is generally quicker, with less hot work required, which can reduce risk during construction in operational healthcare environments.

However, CMT has limitations in critical medical gas applications. Material permeability, joint integrity, and compatibility with specific gases require close review of manufacturer certifications and local code acceptance. While CMT performs well in lower-pressure systems, rigid copper or stainless steel may remain preferable in high-demand or life-support scenarios due to superior mechanical durability and reduced risk of contamination or fatigue.

Use of CMT should be considered on a case-by-case basis, guided by NFPA 99 compliance, AHJ requirements, and long-term system performance expectations.
