A gas riser apparatus for conducting gas from a souce of supply to a delivery point such as a meter or the like. The gas riser apparatus is defined by a plastic pipe and a metal pipe which are interconnected within the body of the apparatus by means of a metal-to-plastic pipe joint. The pipe joint includes a reinforcing metal stiffener sleeve and a nonmetallic outer sleeve tightly surrounding the metal pipe and the plastic pipe.

Gas riser apparatus

A gas riser apparatus and method for conducting gas from a source of supply to a delivery point such as a meter or the like. The gas riser apparatus is defined by a double walled conduit including an inner tubular member and an outer tubular member. Sealing structure is provided at the double walled conduit for the purpose of sealing the riser apparatus. The method of the invention is directed to method steps for conducting gas from a source of supply below ground level to a delivery point above ground level.

Gas riser apparatus and method

An anode-fitting assembly for use in hot water tanks, pipelines or the like wherein an interior metallic surface undergoes corrosion when exposed to electrolytic fluids such as air and water. The fitting element of the assembly is comprised of a hollow nipple or connector member adapted to be threadedly received within an opening of the water tank, pipeline or the like. A tubular intermediate member extends from the nipple. An impervious electrically insulating plastic covering is provided on the exposed external surface of the tubular intermediate member. The anode element is comprised of a cylindrical electrode telescoped within the tubular intermediate member of the fitting and secured thereto by joining means that permits the anode element to be assembled to the fitting element at any convenient time after assembly of the fitting and prior to installation of the anode-fitting assembly in the water tank, pipeline or the like. In the preferred embodiment an impervious fluid passageway is provided within the fitting element such that the anode-fitting assembly may be used as an anode holder and fluid outlet.
