IN STOCK: Black-Steel pipe is less expensive than CSST and is a type of conduit used for natural gas heating in homes.
Corrugated Stainless Steel Tubing (CSST) is a type of conduit used for natural gas heating in homes. It was introduced in the United States in 1988. CSST consists of a continuous, flexible stainless-steel pipe with an exterior PVC covering. The piping is produced in coils that are air-tested for leaks. In the United States, about 500,000 new homes per year have CSST installed; that number is about half of the number of new homes that have natural gas for heating or cooking.As of 2007, about 2 million homes in the United States had CSST installed. CSST is installed much like electrical wiring, and thus more quickly than traditional black-steel pipe,but the cost of the material is several times more than black-steel pipe. In mid-2007, four CSST makers settled a class-action lawsuit. The settlement provides money to fix problem pipes The settlement provided money to fix problem pipes by bonding the CSST to the electrical systems with thicker wire.
