It is required to replace the old firetube A-106gr. B WITH PIPE API 5L (IN STOCK ) as a material for firetube for heater treater (vessels that contain liquids produced from wellheads. Heat is introduced to the liquids through the use of a natural gas or hydrocarbon liquid burner that is mounted inside of a flanged firetube assembly that projectes into the vessel. The firetube assembly typically consists of a flat, round or obround pressure retaining cover (one of the vessels main bolted closures) that is penetrated by a U-tube which houses the burner and directs combustion gases to a vertical, atmospheric exhaust stack external to the vessel).
