Abstract:
A safety valve arrangement and method, having an upstream block valve, a downstream block valve, and a pressure monitored galley between the upstream valve and the downstream valve.
Abstract:
A two way cross clean-out pipe fitting, used to access underground drain and sewer lines for the purpose of cleaning and removal of blockage. It consists of two access ways aboveground that lead to the underground line. Prior to the tool reaching the underground line, it travels through long radius bends that guide it in the preferred direction without the use of additional tools and eliminates trial and error issues. Each access way determines the direction for the cleaning tool to travel, which is opposite to one and other.

본 발명은 수배관 시스템에 관한 것으로, 보다 상세하게는, 압력탱크 내부에 유체가 장기간 체류함에 따라 발생하는 수질 저하를 방지하고, 압력탱크 및 배관 내부의 공기 및 기타 이물질을 제거하기 위한 수배관 시스템 및 그 제어 방법에 관한 것이다. 본 발명은 유체를 가압하는 펌프와; 상기 펌프에 의해 가압된 유체를 이송하는 주배관과; 상기 주배관의 펌프 토출측에 구비되는 주밸브와; 상기 주배관에 연결되는 압력탱크와; 일단은 상기 주배관의 주밸브 전단측에 연결되고, 타단은 상기 압력탱크에 연결되어, 상기 펌프로부터 가압 토출되는 유체의 일부를 압력탱크로 이송함에 따라 압력탱크 내부 물질을 외부로 배출시키기 위한 보조배관을 포함한다.
Abstract:
A system and methods for predicting structural failure of at least a portion of a wall of a fluid containment vessel. The wall has an innermost layer for contact with a fluid contained by the vessel and an outermost layer parallel with the innermost layer. The system includes strain-sensing means within a portion of the wall and surrounded by the at least one reinforcement layer including at least one conductor parallel to the innermost layer of the wall. Changes are sensed in an electrical property associated with the at least one conductor resulting from distortion of the wall of the vessel causing distortion of the at least one conductor.
Abstract:
A female coupling device (200A) includes: a main body (204A), and a clip member (250) coupled to the main body (204A), the clip member (250) having a plurality of arms (274A, 276A) extending perpendicularly therefrom, with the plurality of arms (274A, 276A) forming at least one pair of arms (274A, 276A), with the pair of arms (274A, 276A) including a first distance (292) therebetween and a second distance (294) therebetween, with the first distance (292) being sized to engage a clip groove (303A) of a mating male coupling device (300A), and with the second distance (294) being sized to disengage the mating male coupling device (300A). In a locked position, the pair of arms (274A, 276A) is positioned so that the first distance (292) is adjacent to the mating male coupling device (300A). In an unlocked position, the pair of arms (274A, 276A) is positioned so that the second distance (294) is adjacent to the mating male coupling device (300A).

Abstract:
A subsea protection cap (1 ) designed for temporary use on a pipe hub (2) to be installed on subsea located equipment is described. The protection cap (1) is designed as a full bore pressure relieve valve and is arranged with resilient retaining means enabling the protection cap (1 ) to lift a limited distance from the end surface (2b) of the pipe hub (2) when subjected for a predetermined pressure increase within the pipe hub (2).
Abstract:
Described herein is an autonomous fluid spill containment device for a pipeline having a carrier conduit for transporting a fluid and a containment conduit located around the carrier conduit to define an interstitial space for receiving fluid spilled from the carrier conduit. The device includes a spilled fluid barrier for stopping spilled fluid flow, which is located in the interstitial space and extends between the carrier conduit and the containment conduit. An acoustic sensor is located in the interstitial space for detecting spilled fluid flowing in the containment conduit, or in the carrier conduit for detecting fluid flow reduction.
