Corrugated Stainless Steel Tubing (CSST) is a flexible, stainless steel pipe used to supply natural gas and propane in residential, commercial and industrial structures.
Besides providing greater durability, CSST is flexible, allowing it to be snaked around walls and through obstacles with fittings needed only at the ends of each run. Reducing the number of fittings is beneficial as each additional joint needs to be fitted and checked for leaks. A CSST gas piping system has less joints, and therefore less potential leak paths。
Like all approved gas piping systems, CSST is safe when properly installed. CSST must be installed by a qualified professional and in accordance with the Manufacturer's Design and Installation (D&I) Guide, including bonding and grounding of the system.
Bonding: Connecting metallic systems to establish electrical continuity and conductivity.
Grounding: Connecting to the ground or to a conductive body that extends to ground connection.
