This company has launched a new mobile application (app) to aid engineers in the proper selection and installation of pipe-penetration seals (pen-seals). Pen-seals can achieve a cost-effective mechanical seal when piping must pass through walls, floors, tanks, pipeline castings or vaults. The Pen-Seal Calculator (photo) is designed to assist in selecting the correct number of links and the correct size of links for pipe penetrations passing through walls or floors. To achieve a 100% water- or gas-tight seal, users can enter the pipe outer diameter and the penetration inner diameter to provide the required size and link combination. The Pen-Seal Calculator app is available for Android and Apple devices. — Proco Products, Inc., Stockton, Calif.
