Fluid management systems for handling pressurized fluid connect various subsystems or subunits without the need to use reinforced tubing. The system utilizes one or more segments of unreinforced conduit that are encapsulated at various points along a length of the segment with one or more rigid encapsulating members. The unreinforced conduit may be made a disposable element while the rigid encapsulating members may be re-used. In one aspect, the encapsulating member may include a two-part valve body that surrounds and encapsulates a portion of the unreinforced conduit. In another aspect, the encapsulating member may include a two-part jacket that surrounds and encapsulates a portion of the unreinforced conduit. The two-part valve bodies and two-part jackets may be joined at various points within the system as part of the overall flow system.

An explosion-proof line bushing and method for producing the line bushing. A prespecified amount of elastomeric material is applied to a line and completely surrounds the line in a flat section in the circumferential direction. The line is inserted into a passage opening of a bushing body. The bushing body is preferably plastically deformed. After the plastic deformation, the elastomeric material substantially fills the volume remaining between the formed bushing body and line. The elastomeric material is elastically deformed and presses both against the line and the formed bushing body so that flame-proof gaps are formed between the bushing body and the line. The applied mass of the elastomeric material is determined depending on the inner volume between the formed bushing body and the line remaining.

This invention encompasses a system and a method used in the petrochemical and mechanical engineering area, more specifically in the area of protecting pipes or similarly shaped objects against external or internal damage or wear, which comprises a protective system for the ends and the inside of coated pipes, using the coating itself and other additional devices. The system is comprised of a cup (1), spacer (2), coating (3), external ring (4), and cap (5) used in the production line of the pipe-coating process, using the external coating itself, preventing corrosion and mechanical damage at the ends/bevel, in the sandblasted area of the collar and internal surface, from storage and transport to the location where it will be used, and welding in the field or on the vessel.

A containment sleeve for use with a pressurized piping system including a pliable fabric sheet having first and second opposing longitudinal edges, first and second opposing transverse edges, and first and second opposing major surfaces respectively defining an interior and exterior surfaces. At least one pleat extends between the first and second transverse edges, the pleat being in a normally closed position to define the interior surface with a first surface area. The sheet of pliable fabric to secure about a portion of a pressurized piping system with the interior major surface facing the pipe so as to form a sleeve having an initial interior volume there about. In response to a rupture of the pressurized piping system within the interior volume, the pleat to expand to an open position to expand the interior surface to a second surface area to increase the interior volume from the initial volume.

A corrugated-tube protective member includes a tubular main body configured to be arranged inside of an end part of a corrugated tube with ridge portions disposed along its longitudinal direction, a rib on an outer circumference of the main body arranged inside the corrugated tube and configured to engage with the ridge portion in a removal direction of the main body from the corrugated tube, and a stopper at an end part of the main body having an outer diameter set to be equal to or larger than that of the ridge portion and configured to be arranged to oppose an end surface of the corrugated tube. An interval between the stopper and the rib is set to be equal to or larger than an interval between engaged surfaces on the ridge portions adjacent to each other, the engaged surface being a surface configured to engage with the rib.

A corrugated-tube protective member includes a tubular main body configured to be arranged inside of an end part of a corrugated tube. At least one portion in a circumferential direction of the main body has a dividing portion dividing the main body in the circumferential direction. The dividing portion includes an engagement portion. The engagement portion holds a first dividing surface and a second dividing surface facing each other in circumferential direction of the main body in an engaged state. The first dividing surface includes a first top part protruding toward the second dividing surface side. The second dividing surface includes a second bottom part indented to an opposite side of the first dividing surface and configured to engage with the first top part. The engagement portion includes a locked part formed on the first top part and an elastically deformable locking part formed on the second bottom part.

A cap for closing an open end of a duct tube has a cylindrical side wall having a length between a closed end and an open end of the side wall. An end wall extends across the closed end of the side wall. A conical section of the side wall extends outwardly from the open end of the side wall and has an interior surface configured to guide an end of a duct tube into a hollow interior volume of the side wall. A groove in an interior surface of the side wall is configured to receive a bead around an end of a duct tube inserted through the conical section and into the hollow interior of the side wall. A plurality of pull tabs extend outwardly from the conical section and are configured to be manually pulled, pulling the cap over the end of the duct tube.

There is provided a pipe thread protector having first and second ends, threading extending from the first end towards the second end thereof, and a bore extending from the first end to the second end thereof. A seal couples to the first end of the pipe thread protector and is tubular. The seal tapers in a direction extending from a proximal end thereof towards a distal end thereof, and tapers in a direction extending from an outer surface thereof to an inner surface thereof.

There is additionally provided a pipe thread protector assembly including a pipe thread protector, a coupling via which the pipe thread protector and a male threaded end of a pipe threadably couple together, and a seal coupled to an inner end of the pipe thread protector. The seal is shaped to protect and extend along an outer end surface of the pipe.

There is provided a pipe thread protector according to a first aspect. The pipe thread protector includes a tubular body shaped to protect a threaded end portion of a pipe or a pipe coupling. The tubular body includes an inner portion with a first of right-handed and left-handed threading. The tubular body includes an outer portion with a second of right-handed and left-handed threading. The pipe thread protector includes an end member. The end member includes the second of right-handed and left-handed threading via which the end member threadably couples to the outer portion of the tubular body. The pipe thread protector includes a locking member with a first position in which removal of the end member from the tubular body is inhibited. The locking member is moveable from the first position thereof to a second position in which the end member is selectively removable from the tubular body.
