摘要： A method and apparatus for introducing a pig into a fluid system is provided. The method comprises providing a coupling in a fluid system. The coupling itself can include a sleeve coupled to a pipe and an end cap. The end cap may include a collar handle and at least one engagement member. The engagement member facilitates selective engagement of the end cap with the sleeve. The end cap is rotated relative to the sleeve to disengage the engagement member from the groove and to open the end cap relative to the sleeve. The groove is configured so that the engagement member can be opened only when the line is de-pressurized. A pig is inserted through the sleeve and into the pipe. The end cap is then coupled to the sleeve by engaging the engagement member with the sleeve and rotating the end cap relative to the sleeve.

摘要： A rotating union (10) comprises a housing (12), a bushing (14), a fluid conduit (16), an annular seal (18) and a cap (20) secured to the housing and having a fluid inlet. The bushing is received within a cylindrical recess (32) in the housing, and the fluid conduit is rotatably received by the bushing and passes through the bushing and a bore (40) in the housing. The annular seal is received within the housing recess, and sealingly engages a cylindrical outer surface (80) of the fluid conduit and the cylindrical wall (46) of the housing recess. The cap has a circular recess (104) and surrounding annular projection (106) which receives the input end of the fluid conduit. The annular seal is sandwiched between the bushing and the annular projection. When the fluid conduit rotates, its outer surface rotates under friction against the annular seal to maintain the seal.

摘要： Copper purge fittings for brazing components of a special gas delivery line together are provided. An orifice is located on the top or end portion of each fitting to create a continuous flow of inert purging gas through the delivery line under construction while brazing. Each fitting will reach temperatures exceeding 1500 degrees. By having a continuous flow of inert gas while brazing, the protection of the interior portion of the system remains intact. Without a purge in place, the intense heat would create a rapid immediate buildup of carbon and other contaminates. Brazing is only commenced after the elimination of harmful oxygen and proper flow of purging gas is measured. The purging gas pressure is lowered if it becomes high enough to potentially cause separation of tubular sections from the purge fittings and is raised if a low flow rate is detected indicating potential insufficient flow of purging gas.

摘要翻译： 提供用于将特殊气体输送管线钎焊零件的铜清洗配件。 孔口位于每个配件的顶部或端部，以在钎焊时产生通过施工中的输送管线的惰性吹扫气体的连续流动。 每个配件将达到超过1500度的温度。 通过在钎焊时具有连续的惰性气体流，系统的内部部分的保护保持完整。 没有吹扫的地方，强烈的热量将会立即形成碳和其他污染物。 消除有害氧后才开始钎焊，并测量排气净化气体的适当流量。 如果清洗气体压力变高到足以潜在地导致管状部件与吹扫配件分离，则清洗气体压力降低，并且如果检测到低流量，表明净化气体的流量不足，则其升高。

摘要： An apparatus for sealing a section of a pipe interior includes a clamp having a magnetic engagement means for axially positioning the clamp within the interior of a pipe and preventing relative axial movement there-between and a sealing plate securable thereto. Movement of the sealing plate against the clamp results in deformation of a resilient sealing member thereby forming a seal between the apparatus and the pipe. The apparatus can be used in conjunction with another oppositely oriented apparatus or other sealing means to form a sealed space within the tube. Pressurization of the sealed space allows for a radial and/or axial force being applied to the sealed section of the pipe.

摘要： A fluid system component is provided that includes first and second elements configured to be removably engaged with each other and defining a fluid passageway when engaged. The first element defines at least one groove. Correspondingly, the second element includes at least one engagement member configured and arranged to be received in, and travel along, a corresponding groove. The presence of a predetermined line pressure in the fluid passageway forces each engagement member into the terminal portion of the corresponding groove, so as to substantially foreclose disengagement of the first and second elements until the fluid pressure in the fluid passageway has reached a predetermined magnitude. The fluid system component includes means for selectively securing the second element, such as a collar, in relation to the first element, such as a sleeve, when the first element is received within the second element.

摘要： A seal assembly for effecting a fluid tight seal between a pipe and an opening in the wall of a structure, particularly a relatively thin-walled structure made of a rigid plastic, fiberglass, or of metal, for example. The seal assembly generally includes a seal ring and an annular nut. The seal ring includes a relatively rigid fastener component having external threads, and a relatively resilient sealing component joined to the fastener component and including a first sealing projection for providing a compressive seal between the seal ring and one side of the structure wall, and a second annular sealing projection for providing a compressive seal between the seal ring and the outer surface of a pipe inserted through the seal ring. The seal ring is inserted through the opening in the structure, and the annular nut is threaded onto the external threads of the fastener component and into engagement with a first side of the wall to thereby compress the first sealing projection against the opposite, second side of the wall. Thereafter, a pipe is inserted through the seal ring to compress the second sealing projection between the outer surface of the pipe and the seal ring.

摘要： Absorbent plugs and caps plug or cap fittings that have been used to inject liquids into various systems. The plugs are sized to fit within the interior body cavity of fittings to absorb the residual liquid that is left in the cavity after use. The caps are sized to fit over the exterior of the fittings to absorb any residual liquid that leaks out from fitting exterior surfaces. The caps can also have interior plug extensions that extend into the interior cavities to also absorb the residual liquid from the interior. The plugs have non absorptive tabs for insertion and removal and the caps have non absorptive exterior skins or coverings to contain the absorbed liquid within the cap. One such use is to plug and/or cap fittings such as R134a service couplers which are used to inject dye into automotive air conditioning systems.

摘要： A waste and overflow system for a bathtub includes an overflow conduit having a threaded end and an overflow cap threaded at one end extending through the overflow opening in the bathtub into threaded engagement with the threaded end of the conduit. The other end of the overflow cap has a test cap portion removably connected thereto for closing off an overflow passage through the overflow cap during pressure testing of the system. The test cap portion is removable from the other end of the overflow cap upon completion of the system pressure test to open up the overflow passage through the overflow cap.
