摘要： An electrical insulated threaded connection includes a conductive box with a plurality of internal threads, a conductive pin with a plurality of external threads, and a double-threaded electrical insulator sleeve disposed between the conductive pin and box. The double-threaded electrical insulator sleeve comprises a plurality of external threads that mate with the plurality of internal threads of the conductive box and a plurality of internal threads that mate with the plurality of external threads of the conductive pin. In certain embodiments, the double-threaded electrical insulator sleeve fills a full volume between the plurality of internal threads of the conductive box and the plurality of external threads of the conductive pin, and there are no voids or pockets between any of the mating threads.

摘要： In a threaded connection for pipe with a two-step thread construction, including intermediate shoulders, during stabbing, the internal-pressure sealing surface of the pin near its tip is prevented from contacting the intermediate shoulder of the box and thus receiving damage. LP, LB, hP and hB shown in FIG. 2 satisfy Expressions (1) and (2), provided below. θseal is the angle of slope of the straight line connecting the two ends, as determined along the axial direction, of the internal-pressure sealing surface of the pin. Expression (3), provided below, is also satisfied.

摘要： A greenhouse comprises a support frame and a spray pipe including pipes and pipe joints, the pipe joint comprises a connecting pipe and two rotary sleeves, the two adjacent pipes are respectively inserted into the connecting pipe, ends of a first pipe are respectively sleeved with a sealing sleeve and a locking sleeve, and each of the ends of the first pipe is further sleeved with a washer. When the rotary sleeve is thread-tightened, the connecting pipe and the locking sleeve are capable of respectively abutting and pressing against two sides of the washer, under abutting and pushing of the rotary sleeve and limiting of the washer, the locking sleeve is capable of grasping the first pipe and forming an axial positioning with the rotary sleeve. An inner edge of an end surface of the connecting pipe has a sealing tapered surface capable of acting on the sealing sleeve.

摘要： A fitting assembly for connection to a flexible duct includes a ferrule configured for insertion into an open end of the flexible duct a fitting removably connected to the ferrule. The ferrule includes a sidewall defining a minor diameter and a major diameter spaced apart from the minor diameter, and a ferrule thread extending radially outward from the sidewall. One of the fitting and the ferrule defines a recess. Another of the fitting and the ferrule comprises a tab configured to extend into the recess. One of the recess and the tab comprises an edge. Another of the recess and the tab comprises a ramped surface extending in a circumferential direction of the ferrule, such that rotation of the ferrule relative to the fitting causes the ramped surface to engage the edge, thereby radially deflecting the tab and disengaging the tab from the recess.

摘要： A threaded connection includes a first tubular member having a pin end defining an external thread profile, and a second tubular member having a box end defining an internal thread profile threadably engageable with the external thread profile of the pin end. At least one of the external and internal thread profiles includes a first section that extends at a first taper angle relative to a longitudinal axis of the threaded connection, a second section extending from the first section at a second taper angle relative to the longitudinal axis, and a third section extending from the second section at a third taper angle relative to the longitudinal axis. The second taper angle is greater than each of the first and third taper angles.
