What is Type L copper pipe and why is it required for medical gas?

Type L copper pipe is a seamless, rigid tubing that is thicker and more durable than Type M, but not as thick as Type K. NFPA 99 mandates Type L (or K) for medical gas systems because its wall thickness provides the necessary durability and safety to handle the pressures and purity requirements of medical gases, minimizing the risk of leaks and system failure.

Who can install medical gas piping?

Only individuals holding an ASSE 6010 credential are qualified to install medical gas systems. This certification ensures the installer has been trained, tested, and is knowledgeable about the specific procedures, codes, and safety protocols required by NFPA 99.

How often does medical gas piping need to be inspected?

Following the initial ASSE 6030 verification, the entire medical gas system, including piping, must be inspected regularly. MTS provides comprehensive [annual medical gas inspections](/medical-gas-testing-and-service/annual-medical-gas-inspections/) to ensure ongoing compliance and patient safety.

What is the final step in a new medical gas piping installation?

The final and most critical step is the third-party verification, performed by an ASSE 6030 Certified Medical Gas Verifier. This process involves a series of tests to confirm system purity, pressure, flow, and absence of cross-connections before the system can be used for patient care. It's the ultimate quality control check.

Can existing buildings be retrofitted for medical gas piping?

Yes, retrofitting existing healthcare facilities with new or updated medical gas piping is a common project. It requires careful planning to minimize disruption to ongoing patient care. Our team at Medical Testing Solutions has extensive experience in executing complex retrofits in live environments.
