An adapter for drainage hole includes a main body having at least one opening defined in a top portion thereof, wherein the main body is a tubular structure. The adapter includes a converging structure radially extending from a lower portion of the main body, wherein multiple converging holes are defined in the converging structure. A fixing structure longitudinally extends from the lower portion of the main body and is adapted to be secured on a filter that is secured in the drainage hole. The converging structure is skirt-shaped and the converging hole is arched-shaped. The fixing structure includes multiple insertions that extend through the filter and extend into the drainage hole for holding the main body in place.

A component used for drilling and operating hydrocarbon wells which is substantially tubular in form, and including a first end configured to be connected to a second end of another component also used for drilling and operating hydrocarbon wells. The first end includes a terminal portion including a first abutment surface configured to cooperate by interference with a corresponding abutment surface on the second end, and including a sealing surface configured to cooperate by interference with a corresponding sealing surface on the second end, the terminal portion being preceded by a threaded zone configured to be made up into a corresponding threaded zone of the second end. A compressible volume is provided in the thickness of the first terminal portion and partially beneath the sealing surface, to reduce radial stiffness of the terminal portion by at least 20%, while conserving at least 60% of axial stiffness.

Methods and systems for protecting a duct joint are provided. An assembly for protecting a joint formed between a first duct and an adjacent second duct includes a first coupling element coupled about the first duct and a second coupling element coupled about the second duct. The assembly also includes a plurality of axial straps coupled between the first coupling element and the second coupling element such that each axial strap of the plurality of straps forms a loop that encircles a portion of each of the first coupling element and the second coupling element.

A loading assembly has a gas conduit that extends between a floating structure and another structure, to convey a pressurized gas stream between the two structures. An emergency disconnection coupler is configured in the gas conduit. A switching system is provided for controlling switching of an engagement mechanism in the emergency disconnection coupler between a locked position and an unlocked position (in either direction). The switching system is subject to two distinct fail-safe regimes: a fail-unlocked regime which inherently instructs for release of the emergency disconnection coupler, and a fail-closed regime which inherently precludes release of the emergency disconnection coupler when there is pressurized gas in the gas connection. The fail-unlocked regime is active when the gas pressure in the gas connection is below a predetermined override threshold value. The fail-locked regime overrides the fail-unlocked regime.
摘要:
A pipe joint for preventing fine particles generated when a male threaded member and a female threaded member are threadedly engaged with each other from entering a fluid passage thus maintaining a high degree of cleanliness. Joint members are joined to each other by a male threaded member formed on one joint member and a female threaded member formed on the other joint member. A cover portion which covers outer peripheral surfaces of abutting portions of both joint members is formed on the male threaded member.

A flexible hose assembly is disclosed. The flexible hose assembly has a first coupling member with a first anti-rotational element on a first end and a crimping element on a second end, the crimping element being configured to receive a first flexible hose. The flexible hose assembly also has a second coupling member with a second anti-rotational element on a first end, the second anti-rotational element being configured to mate with the first anti-rotational element. The flexible hose assembly also has a clamping ring configured to retain the first ends of the first and the second coupling members together.
摘要:
A connector for a length of corrugated tubing. The connector includes a fitting including a passage therethrough, a clamping surface, a seal, and a nut operably connected to the fitting. The tubing is in fluid communication with the passage through the fitting. Axial movement of the nut towards the clamping surface-urges the tubing against the seal wherein the tubing is thereby sealingly restrained to the fitting and a clamping surface is formed capable of causing an end portion of the corrugated tube to form a flare by the end portion of the corrugated tube being compressed against the clamping surface and the seal and sealed thereagainst by the action of the nut.

A pneumatic connector is provided. The pneumatic connector includes: a body having two ends; a first connecting structure at one end of the body; a second connecting structure at the other end of the body, wherein the first and second connecting structures are substantially in line with each other; and a third connecting structure located in between the first and second connecting structures at an angle that is not in line with the first and second connecting structures, wherein the first second and third connecting structures are fluidly connected to an interior of the body, wherein the first, second and third connecting structures are adapted to permit substantially leak free connections between pneumatic components. A method of creating an accessory connection for a bead seater is provided.

The present disclosure is directed to a method of welding a gasket to a spigot portion of a pipe section. The method includes supporting the gasket in a recess on the spigot portion of the pipe section. The gasket includes a seating portion and a sealing portion. The sealing portion includes a first shoulder portion and a second shoulder portion. A first bonding portion extends from the first shoulder portion and a second bonding portion extends from the second shoulder portion. The first bonding portion and the second bonding portion are provided to bond the gasket to the spigot portion. The method further includes heating a portion of the gasket and an adjacent surface of the spigot portion and applying a force onto the portion of the gasket following the application of heat to fuse the gasket onto the spigot portion.

A multi-layer bell is formed from the outer shell of a multi-layer pipe in a secondary process, thereby allowing the extrusion process to be conducted at normal speeds. The bell may include a strain limiting membrane fused or mechanically secured between the outer shell extrusion layer and the inner liner extrusion layer, increased hoop or circumferential stiffness. This invention allows the extrusion process to be in its simplest form, with no adjustments to the corrugator or extruder speeds.
