A protector for the male or female end of a threaded tubular connection for drilling or operating hydrocarbon wells, comprising a principal body, a first sealing gasket formed from a material which is less rigid than the material of the protector body and intended to make a seal with a surface of an end of the component, the principal body comprising a plurality of orifices through which the sealing gasket passes.

A protector for a connection for a tubular component for drilling or operating hydrocarbon wells, provided with a distal end surface, the protector comprising an annular housing comprising a bottom, two lateral walls, outer and inner, separated from each other and in which an annular gasket is disposed, each lateral wall comprising a bottom lateral wall portion and an exterior lateral wall portion and an upper face, the two exterior lateral wall portions defining an opening with width A.sub.u and characterized in that a distance A between two bottom lateral wall portions is greater than the width A.sub.u, in a manner such as to allow a first annular gasket to be positioned then to allow said annular gasket to be retained in the annular housing.

A housing connection for connecting at least two adjacently placed exhaust gas housing end sections or exhaust pipe end sections of an exhaust gas housing or exhaust pipe, wherein the housing connection includes a spacer element which can be introduced between the two end sections, and wherein at least one retaining part is provided, configured as a retaining band, with at least two ends, which can be applied onto a circular shape of the exhaust gas housing or exhaust pipe end sections which are to be connected, and which at least partially circumferentially surrounds the respective end section, wherein the respective end is secured to the spacer element, and wherein the spacer element can be brought into contact against the respective exhaust gas housing end section or exhaust pipe end section, at least indirectly by way of the retaining band, or directly.

A sealing element for pipes comprises a body made up of a section of stem that has a circular plant head region at one end that acts as a grip area. The stem section includes in a downward direction from the head region a plurality of parallel positioning regions with a substantially discoidal shape, having a primary positioning region that has a larger diameter than remaining secondary positioning regions. The primary positioning region has two sections devoid of material diametrically opposed to each other, so as to define two opposite fins capable of bending. A positioning region adjacent to the primary positioning region in a direction to head region has two sections devoid of material which are offset by 90 degrees with respect to the positioning of the two sections devoid of material of the region of primary positioning.

An assembly for forming a mechanical interface for fastening tubular components includes a tubular pipe having at least one end with an external surface provided with groove structure. A tubular attachment is provided with a first engagement structure configured to be aligned with the groove structure on the tubular pipe. The tubular attachment is axially force fit on the outer end of the tubular pipe, and radially fastened thereto in response to at least one tool applied to the external surface of the tubular attachment. Also disclosed is a method for forming the mechanical interface between the tubular pipe and the tubular attachment.

A thread protector comprises a hollow cylindrical body with a substantially closed end and a threaded inner annular wall extending from the substantially closed end. An annular ring extends inwardly from the substantially closed end. The annular ring has a sloped wall which is spaced-apart from and faces the threaded inner annular wall.

A protective cover structure of a water hose includes a water hose connector, a rigid protective cover, and at least one sealing member. The water hose connector has elasticity. A front end of the water hose connector is formed with a mating portion for connecting with a spray nozzle. A rear end of the water hose connector is formed with a concave step and a connecting portion. A rear end of the metallic press member is inserted into the water hose. A front end of the metallic press member is formed with a mating cap having an evaginated rim. The concave step of the water hose connector is movably mated with the metallic press member through the evaginated rim of the mating cap, such that the spray nozzle can be turned at will relative to the water hose and won't be turned reversely, twisted, bent.

A thread protector that has an external sleeve to protect threads disposed on a tubular member. The thread protector includes a flange disposed on a first end of the external sleeve to be engageable with an end of the tubular member. The thread protector also includes a securing apparatus extending from the flange to frictionally engage an inner side of the tubular member to maintain the thread protector's engagement with the tubular member, the securing apparatus including a magnet that increases the force of the frictional engagement of the securing apparatus with the inner side of the tubular member. The securing apparatus can also extend from the flange to frictionally engage an inner side of the tubular member to maintain the thread protector's engagement with the tubular member, the securing apparatus rotatable relative to the external sleeve. A method of protecting pin threads of pin ends of tubular members by installing a thread protector on an end of a tubular member.

A carbon fiber reinforcement for reinforcing a pipe connection between two pipes includes a carbon fiber composite having a substantially circular cross-section, a length, a central axis along the length, an outer surface, and an inner surface, wherein the outer surface of the reinforcement is configured to bond with an inner surface of one of the two pipes. A method for reinforcing a pipe connection between two pipes includes forming a carbon fiber composite reinforcement having a substantially circular cross-section, a length, a central axis along the length, an outer surface, and an inner surface, and bonding the outer surface of the reinforcement to an inner surface of one of the two pipes.
