Through-The-Wall-Connection
ModuTank Inc. has developed a flange type bulkhead fitting featuring a single hole penetration for the pipe. 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 walls. The new fittings are available in PVC and stainless steel in standard sizes for 2" to 24" piping. They are equally suitable for new and existing steel, and for concrete tanks with or without epoxy or glass coatings, or with membrane liners. Expansion joints are normally supplied to eliminate stress problems due to misalignment or tank wall flexing. Exterior piping and ancillaries are attached to outside flanges on expansion joints.
