This technology promises time savings and a better result, but can contractors accept it?
Corrugated Stainless Steel Tubing (CSST) was introduced to the American market in 1987, when it became listed by the American National Standards Institute (ANSI). Prior to this, CSST had been used in Japan and Europe since 1980 with excellent results. It was hailed as one of the greatest technological advances in delivering fuel gas to residential appliances. The steel tubing had several advantages over black steel pipe, which had been used for fuel gas for the past century.
One of the most dramatic benefits of the new material was the amount of installation time it could save. Even though CSST was substantially more expensive than the traditional black steel, its overall price, including labor and material costs, was cheaper than black pipe.
