Description:
TDW's closures are devices that allow quick and easy access to the inside of a pressure vessel. Closures are used on pig launchers and receivers and other pressure vessels such as filters and strainers. All closures have a safety, pressure warning lock, which must be opened prior to accessing the closure to alert the operator to any pressure in the trap |
