A tube connector includes a body. A fluid channel is formed inside the body. A first connecting portion configured to be connected to the round tube and a second connecting portion configured to be connected to the flat tube are formed on the body. The first connecting portion is a hollow columnar structure. The second connecting portion includes an oblong interface. A weld face that fits a shape of the flat tube is formed on an inner sidewall of the interface.

A connector for a fluid line includes a sleeve having a hollow portion at least partway therethrough. The sleeve includes an engaging portion. A collet having an engaging part is secured to the engaging portion. A grab part has one or more teeth configured to retain the fluid line, and the teeth are located in the hollow portion. A locking part is provided having a locking portion, and the locking part is configured to move from a first position to a second position where the locking portion locks with a locking piece to assist with forming a fluid seal with the fluid line.

A containment pipe fitting has an inner member (40; 260), an outer member (42; 262), and a plurality of centralizers (48) positioning the inner member within the outer member. The fitting has at least one connection interface (37; 38; 39; 254; 255) having an internal surface portion (72) of the inner member sized to receive and join a portion of an associated inner/main pipe (31; 32; 33) and an internal surface portion (80) of the outer member sized to receive and join the portion of an associated outer/containment pipe (34; 35; 36). The connection interface further includes an external surface portion of the outer member dimensioned to receive a closure coupling or collar (100; 100′).

A coupling apparatus that is attachable to a substantially tubular element having a passageway extending therethrough. The coupling apparatus has a coupling body and at least one adapter. The coupling body has a passageway extending therethrough and at least one leg having at least one annular groove. The adapter has a passageway extending therethrough and a radially extending inward portion for engaging the annular groove on the leg of the coupling body for connecting the adapter to the coupling body. The adapter is connectable to the tubular element for forming a continuous passageway through the coupling apparatus.

In a hose having a bent portion, a poor appearance part is prevented from being created in an inner round portion of the bent portion. A bent pipe has a bent portion located in an intermediate part in a longitudinal direction in which a cross section in a radial direction of a round of the bent portion is formed in a flat shape, and non-bent portions being continuous with the bent portion. The flat shape of the bent portion is a vertically long flat shape. With this configuration, when an unvulcanized hose is put on a mandrel and vulcanized, an inner round portion of the unvulcanized hose comes into tight contact with a bent portion of the mandrel and is not separated from the bent portion, so that the poor appearance part is hardly created in an inner round portion of the bent portion.

The polymeric pipes reinforced with a metal casing are used for transporting oil and gas, acids, alkali products, drinking water and industrial water, and also in the transportation of aggressive and neutral pulps. A metal-containing polymeric reinforced pipe includes a welded metal casing and a polymeric matrix having an amorphous-phase-based molecular structure. The metal-containing polymeric reinforced pipe is produced by extrusion moulding with simultaneous feeding of a polymer melt and the reinforcing metal casing into the mould cavity, followed by intensive cooling of the internal and external surfaces of the pipe being moulded. The invention increases the quality and endurance limit in the radial direction of the metal-containing polymeric reinforced pipe, productivity of the process for manufacturing the pipe, and also the strength and technological effectiveness of a pipeline constructed from the pipes produced.

A vent duct having an inner fluid flow passage includes a bent portion formed to a duct body portion at which the fluid flow passage is bent, and a protruded portion formed on a downstream side of the bent portion so as to protrude from an inner peripheral surface portion toward an axial center of the fluid flow passage, wherein the protruded portion includes an upstream side end portion formed to be gently continuous to the inner peripheral surface portion of a downstream side portion of the bent portion, a body portion extending from the upstream side end portion toward the downstream side portion along the fluid flow passage, and a downstream side end portion along the fluid flow passage to be continuous to the body, the downstream side end portion of the protruded portion being formed to be perpendicular to the inner peripheral surface portion.
摘要:
A pipe fitting includes a pipe fitting body having a first end in fluidic communication with a second end, the ends configured to receive a pipe. At least one of the first or second ends comprises a non-circular sectional shape having a low flow enhancement channel disposed at a bottom. The low flow enhancement channel is configured to comprise a first depth of a fluid that is greater than a second depth of the same fluid in a substantially circular section pipe where the non-circular sectional shape and the circular section pipe comprise substantially the same overall cross sectional area. A stand may be associated with the pipe fitting, the stand configured to accept the pipe fitting body in an orientation where the low flow enhancement channel is disposed at the bottom of the non-circular shape.

A connector for a flow managing device in fluid communication with an outlet conduit is disclosed. The connector can comprise a receiving member, an engaging member, and an adapter. The receiving member can be secured to the adapter, which can be secured to a side wall of a basin near an outlet coupled to the outlet conduit. The adapter can comprise a curvature plate having a curvature that complements a curvature of the side wall. The adapter can further comprise an adapter bore through the curvature plate and an adapter conduit extending from the curvature plate and at least partially overlapping the adapter bore. The flow managing apparatus can be secured to the engaging member, which can be engaged with the receiving member. Fluid from the basin can flow through the flow managing device, the engaging member, the receiving member, and the adapter and into the outlet conduit.

An insert, a pipe assembly, and a method for forming a pipe assembly are disclosed. The pipe assembly includes a hollow body and an insert bonded to the hollow body. The insert spans a knit line defined in the hollow body. The insert is formed from a fiber reinforced polymer material. The fibers are generally anisotropic, and preferably unidirectional, and the insert is oriented such that the fibers extend at an angle to the knit line and thus span the knit line. Preferably, the fibers extend perpendicularly to the knit line. The use of an insert having such an orientation reinforces the hollow body, particularly at the knit line. Thus, the use of such an insert bonded to a hollow body according to the present disclosure produces a pipe assembly having increased pressure ratings.
