| Petersen can manufacture Annular Seals for almost any size, pressure, chemical, and temperature requirements. Annular seals can be made with a continuous seal to slip over the end of a pipe or open-ended to form around a pipe already in place. The Petersen® Multi-Flex™ Annular Seals are very flexible, easy to install, and have many inflation connection options. These seals are ideal for bypassing a pipeline during repairs or any other temporary small to large pipeline connection. | |
| Custom flexible and inflatable products are available from materials applicable to most temperature and chemical requirements. A few of the many woven and non-woven materials used in the past include Canvas, EPDM, Kevlar, Neoprene, Nitrile, nylon, Polyurethanes, Polyester, Polyethylene, Polyvinylchloride, Viton, Viton Extreme, etc. | |
| Custom Inflatable Duct Balloons, Bladders, and Isolation Dams for most Chemical, Pressure, and Temperature Requirements. | |
| Petersen manufactures most size heavy duty inflatable bags for sealing off large mine shafts, drifts, tunnels, and canals for emergency, abandonment or maintenance. The small deflated size makes them ideal for installation through confined spaces. These inflatable items are made for a specific project to meet pressure, temperature, and chemical requirements. They are generally inflated with air, inert gas, water or concrete. | |
