Abstract: Method and arrangement for providing a coupling device for conduits of pressurized media which consists of (includes) at least two coupling parts (1, 2) that are possible to couple to each other in the shape of a female part and a male part which is insertable into the female part. A locking device is arranged to hold the coupling parts completely coupled in a locking position. The locking device comprises a locking member (11) positioned at one of the coupling parts (2) which in a locking position attaches into a recess (12) in the other coupling part. A sealing member (6) in the locking position achieves sealing between the coupling parts. The other coupling part (1) exhibits a further recess (16) in which the locking member can be brought to locking of the coupling parts (1, 2) in an outer locking position when the two coupling parts are coupled to each other. In the outer locking position there is incomplete sealing with the two coupling parts being locked so that they are prevented from coming apart but are incompletely coupled together and allowed to be brought together to said locking position for the complete coupling of the coupling parts. In the presence of pressurized media, this enables an indication that the outer locking position has been assumed due to the presence of leakage of pressurized media. The leakage is obtained via a leakage groove (20) which is angled towards the radial plane of the coupling parts. The leakage groove can thus be made by means of rotating machining.

Abstract: A method for controlling fluid leaks in a pipe connection. A first step involves providing a clamp having a circular clamping face with a diversion channel positioned in the circular clamping face and a drain outlet in communication with the diversion channel. A second step involves clamping the clamp around a pipe connection so that any fluids leaking from the pipe connection can only escape by being diverted to the diversion channel. A third step involves positioning a container relative to the drain outlet, so that any fluids passing through the drain outlet from the diversion channel are captured in the container.

Abstract: A method and apparatus for preventing leakage from a fitting coupling a first and second fluid supply line to an environment surrounding the fitting is generally provided. In one embodiment, a containment apparatus includes a body having a first, second and third aperture formed therethrough. The body defines interior volume that is adapted to substantially enclose the fitting. The interior volume is adapted to be maintained at a pressure less than the surrounding environment to prevent fluid that may leak from the fitting from being released into the surrounding environment. In another aspect of the invention, a method for preventing fluid leakage from a fitting coupling a first and second conduit from entering an environment surrounding the fitting includes enclosing the fitting in a volume defined between a first shell and a second shell, evacuating the volume, and drawing air into the volume from between the shells.

Abstract: The invention is to provide a high pressure fuel injection pipe for a diesel engine wherein a fuel, leaked from a seat port is discharged to the outside of a head cover without leaking into the head cover so that a leakage of fuel can be promptly detected and is directed to the high pressure fuel injection pipe formed by abutting and engaging a pressure portion formed on a connecting head of a fuel injection pipe body to a pressure receiving seat portion of a counterpart member so as to provide a firm connection of the fuel injection pipe body to the counterpart member by screwing a fastening nut to press the connecting head to the counterpart member, wherein an annular washer having at least one groove or through hole formed in a radial direction on the circumference of the washer and a seal member is disposed in the vicinity of an outer end portion of a threaded engagement potion defined between the fastening nut and the counterpart member so that a fuel leaked into the inside of the fastening nut from a seat portion defined between the pressure seat portion formed on the connecting head and the pressure receiving seat of the counterpart member may be discharged to the outside through the groove or through hole. Alternatively, the leaked fuel may be discharged to the outside through a through hole which is formed on the fastening nut.

Abstract: A coupling device includes a coupling body, an expandable ring, a washer and a press guide tube. The coupling body includes a substantially cylindrical coupling head and a screw rod; wherein the coupling head consists essentially of an obliquity portion and a receiving portion, a longitudinal slot being provided within the coupling body and passing therethrough, the longitudinal slot communicating with the gas or liquid inside a to-be-detected device or object. The expandable ring and the washer are respectively fitted onto the receiving portion of the coupling body. The expandable ring is provided to enable the coupling body and a circular slot to be coupled tightly. The washer prevents the gas or liquid leakage from the contact surface between the coupling body and the circular slot.
