A line of flange-type bulkhead fittings featuring single hole penetrations is offered by Modutank Inc. These modular tank pipe fittings minimize potential leaks by eliminating through-the-wall bolts and bolt holes. They are sealed to the tank wall with gasketing and a unique external pressure plate system. Expansion joints are normally supplied to eliminate stress, piping misalignment and tank wall flexing. Exterior piping and ancillaries are attached to outside flanges of expansion joints. Available in standard sizes from 2 -12 inches and up in carbon steel and stainless steel, the flanges are designed for new and existing steel, fiberglass, membrane lined and concrete tanks.

Piping Connections - Through-The-Wall-Connection

ModuTank Inc. has developed a flange type bulkhead fitting featuring a single hole penetration for the modular tank piping connection. Bolts do not penetrate the steel wall or liner, thereby greatly reducing the potential for leaks. Tight leak-resistant connections are achieved by adjusting pressure on wide, thick gaskets that seal the fittings to the wall. The fittings are available in stainless steel, carbon steel and PVC in standard sizes from 2” to 24” piping. They are equally suitable for new and existing steel, concrete, and plastic tanks and for tanks with membrane liners. Expansion joints are supplied to eliminate stress problems due to piping misalignment or tank flexing. Exterior piping and ancillaries are attached to outside flanges on expansion joints.
