  • Patent number: 8616585
    Abstract: A pipe joint includes a first pipe that includes a first flange and a second pipe that includes a second flange. A first sleeve is installed within the first pipe and a second sleeve is installed within the second pipe. Further, an annular ring is positioned between the flange of the first pipe and the flange of the second pipe. The annular ring includes a first hub that extends into the first pipe and a second hub that extends into the second pipe. Moreover, a first complementary engagement structure is formed between the first sleeve and the first hub of the annular ring. The first complementary engagement structure provides a first seal interface within the pipe joint. A second complementary engagement structure is formed between the second sleeve and the second hub of the annular ring. The second complementary engagement structure provides a second seal interface within the pipe joint.

  • Patent number: 8573655
    Abstract: An apparatus for sealing an open end of a pipe includes a clamp for frictionally being secured to the exterior of the pipe, a sealing plate for covering the open end of the pipe and being connectable to the clamp, and an urging mechanism for urging the sealing plate towards the clamp and for forming a seal between the sealing plate and the open end of the pipe. In one aspect, the clamp comprises an annular body formed by at least two sections that are radially tightened over the pipe exterior. In another aspect, the clamp comprises cooperating annular bodies, one capable of radially narrowing the other for frictionally engaging the pipe outer surface. In another aspect the method provides a method of sealing an end of a pipe. According to the invention, once the open end is sealed, the interior of the pipe may be pressurized, for example for testing the integrity thereof.

  • Patent number: 8567508
    Abstract: A change-out flange suited for use at an existing head casing of an oil or gas production well. The change-out flange is devised to replace standard hammer caps atop a well casing. By the present invention, with comparative ease a variety of wellhead equipment can be removably and interchangeably secured to the wellhead using an existing casing bowl or spool. The change-out flange has a casing hub that can be screwed unto a known casing bowl, and an integral connection flange provided with a plurality of connection holes arrayed in a manner consistent with the connection hole arrays of an assortment of conventional wellhead devices such as valves. A variety of well head devices thus can be more readily removed from, and securely replaced upon, the change-out flange. Lockdown pins are insertable into the change-out flange in a manner which secures the tubing hanger in place within the casing bowl.

  • Patent number: 8528763
    Abstract: The present invention relates to a pressure vessel (1) for a high pressure press comprising at least a first sub-cylinder (4) and a second sub-cylinder (6), which are axially connected to form a cylinder body (2) for enclosing a high pressure medium, and a sealing arrangement arranged at the inner wall of the cylinder body for sealing the joint (3) between the first and the second sub-cylinder (4, 6) against leakage of the pressure medium. The sealing arrangement is comprising a ring shaped sealing band (18), a first circumferential protruding flange (30), which is arranged on the inner wall of the first sub-cylinder and which axially extends from the joint (3) and away from the second sub-cylinder (6), and a second circumferential protruding flange (32), which is arranged on the inner wall of the second sub cylinder (6) and which axially extends from the joint (3) and away from the first sub-cylinder (4).

  • Patent number: 8517430
    Abstract: A coupling for securing pipe elements together in end-to-end relation is disclosed. The coupling has segments joined end-to-end by adjustable connection members. The segments surround a central space which receives the pipe elements. One or more gripping bodies are captured between the segments. The gripping bodies are arranged opposite to each other. When the segments are drawn toward each other by the connection members, interaction between the reaction surfaces and the contact surfaces forces the gripping bodies radially inwardly. Inwardly facing arcuate surfaces on the segments and the gripping bodies engage and retain the pipe elements.

  • Patent number: 8505983
    Abstract: A flange connection for connecting e.g. two sections of a tube or pipe comprises two flanges and a sealing ring inserted into an annular sealing space defined by radial faces and axially extending peripheral walls between the flanges. The sealing ring has an annular main body and an outer periphery with a cross-sectional shape that has legs extending outwardly from the main body. These legs, in a condition prior to application of sealing pressure, are inclined away from each other and have rounded outer ends that abut both the radial faces and the peripheral walls defining the annular sealing space. The legs, in a condition where the flanges are forced against each other, are axially compressed and upset at least in a radial direction by plastic flow of material on the outer ends in sealing engagement with the axially extending peripheral walls.
