quick opening
Pipeline Equipment, Inc. has designed and developed a new quick release closure. This innovative, patented locking system is secure and easy to operate and can be used in a wide range of applications. With over 15 years of engineering, design, and machining experience, Pipeline Equipment, Inc. can design closures to customer specifications and deliver fast turnarounds.
easy to operate
The closing operation can be carried out by a single person without the use of tools. The integration of the locking segments, the locking mechanism and the door handle in the door provides a compact and efficient design. To open the door, the handle requires only a quarter turn, which moves the locking segments out of their stowed position. The internal components of the locking mechanism are protected by a weather seal and are stainless or plated to protect against rust and corrosion. The o-ring groove is machined into the gate with the hub o-ring seat area recessed to protect the seat during scraper launch and reception. This configuration ensures a positive seal when the door is closed and locked.
integrated double lock
Safe operation of the closure is ensured by a redundant design in which the closure cannot be opened without removing the pressure alert valve and moving the safety lock. The pressure alert valve also provides the operator with an indication of the presence of any residual pressure in the vessel in the event the operator inadvertently attempts to open the closure before all pressure in the vessel is relieved. Additionally, the safety lockout mechanism prevents the door handle from moving to the open position until the pressure alert valve has been safely withdrawn. The safety lock must also return to the locked position for the pressure alert valve to install.
