摘要： A pipeline connection device includes a first connecting member, a second connecting member and a sealing member. The first connecting member includes a first channel and an abutting portion. The second connecting member includes a second channel and a first groove portion. The first groove portion includes a first side wall and a first receiving groove to receive the sealing member. At least part of the abutting portion is received in the first receiving groove and abuts against the sealing element. A first gap not greater than 0.3 mm is provided between the abutting portion and the first side wall; or the first connecting member and the second connecting member include at most two annular friction surfaces. As a result, mutual jamming of the first connecting member and the second connecting member can be avoided. Besides, a pipeline adapting assembly having the pipeline connection device is disclosed.

摘要： A flange connection set includes a modified compact flange, having a channel for external-internal seal tests, coupled to a connecting component, and coupled between the compact flange and the connecting component, there is a KX sealing ring with a radius closer to the radius of the conduit. Different types of keys provide the flange connection the ability to withstand high shear and torsional loads without affecting its operation, while also resisting high bending moment loads and preserving the integrity of the sealing ring and the fasteners.

摘要： A ducting system includes an elongate duct section or length and formed flange connectors at each end of the duct. Both the duct section and the flange connectors are elliptical in cross section, defined by a major axis and a minor axis. The elliptical cross section has the advantage of reducing the overall height of the duct system along minor axis, as well as defining a rigid structure due to there being no flat surface about the circumference of the duct, while also capable of transporting a significant volume of air relative to a circular duct system of the same size perimeter.

摘要： A threaded flange for a flexible tank that has a base, an upstanding passage, an upstanding support assembly and a grasping member. The base has an upper surface, and a lower surface opposite the upper surface, and an outer perimeter and an inner opening. The upstanding passage extends upwardly away from the upper surface of the base and has a lower end and an upper end, an inner surface and an outer surface, with the inner surface being threaded. The upstanding support assembly comprises a plurality of ribs extending outwardly from the outer surface of the upstanding passage and upwardly from the upper surface of the base. The grasping member is accessible from the lower surface of the base, wherein the grasping member is accessible by and structurally configured for coupling with a tool.

摘要： A method of manufacturing a joint flange using a thickness-increased, machined pipe is provided. The method includes a pipe cutting operation in which a pipe is cut to a predetermined length, a flange forming operation in which a flange having a mounting hole for installing the pipe is formed by die casting, a bump-forming operation in which a thickness-increased part, which is formed by increasing a thickness of one end of the pipe, is bumped to form a first bead locked to the flange, a machining operation in which a circumference of the thickness-increased part is machined to form a sealing groove having an O-ring installed, and a fixing operation in which the pipe is inserted in the mounting hole of the flange and the other end of the pipe is pressed to form a second bead so that the pipe is pressed to a lower end of the flange.

摘要： A pipe connection swivel joint assembly includes a pipe member having an end flange with a conical proximal surface. A split ring assembly includes a pair of swivel ring halves each having a conical inner surface disposed against the conical proximal surface of the pipe member. The pair of swivel ring halves further include a plurality of mounting holes extending axially through the pair of swivel ring halves and a plurality of ring fastening holes. An outer ring is connected to the pair of swivel ring halves by a plurality of split ring fasteners engaged with the plurality of ring fastening holes. The outer ring supports a pair of distance plates that are disposed between opposing ends of the pair of swivel ring halves.

摘要： A flanged joint is described. The flanged joint has a first flange member with a first sealing surface and a second flange member with a second sealing surface. The flanged joint further has a hollow-metal gasket between the first flange member and the second flange member, and a spacer between the first flange member and the second flange member. The spacer defines a minimum distance between the first flange member and the second flange member. The flanged joint can be configured to seal a metal-conveying volume.
