摘要:
A flexible polymeric pipe for transportation of oil, gas or water, having an unbonded reinforcing intermediate layer between two polymeric layers. The pipe has a vent for the intermediate layer which allows venting of gas from the intermediate layer through to the exterior environment. The vent is generally impervious to water but pervious to air and gas.
摘要:
A polymeric product with at least one surface subject to wear or abrasion, at least a portion of which product includes microcapsules of an indicator substance which is released to indicate a state of wear has been reached. The microencapsulated indicator substance may be a fragrance or a colorant. The indicating portion or zone may be a layer or a thin sheet of microcapsules in rubber or in the polymeric material making up the body of the product. There may be more than one indicating layer or zone in the product. The various zones may contain different fragrances or colorants, which may provide progressive indication of the state of wear.

Die Erfindung betrifft ein Verfahren zum Verschweißen kaltgewalzter Schmalbänder (5) in Form von Flachdraht oder Profilen aus einem TWIP-Stahl, insbesondere für den Einsatz in flexiblen Rohren (1), insbesondere in flexiblen Rohren (1) für Offshore-Anwendungen, bei dem die Enden (7) der zu verschweißenden Abschnitte des Schmalbandes (5) relativ zur Hauptbelastungsrichtung (8) des Schmalbandes (5) abgeschrägt ausgebildet und zueinander passend angeordnet werden und die Schweißnaht (9) durch ein Schmelzschweißverfahren mit einer relativ kleinen Aufschmelzzone und/oder einer relativ geringen Schweißtemperatur ausgeführt wird. Ebenfalls wird ein kaltgewalztes Schmalband (5) in Form von Flachdraht oder Profilen aus einem TWIP-Stahl, insbesondere für den Einsatz in flexiblen Rohren (1), insbesondere in flexiblen Rohren (1) für Offshore-Anwendungen, vorgeschlagen, bei dem die zu verschweißenden Schmalbänder (5) jeweils zueinander passende, zur Hauptbelastungsrichtung (8) des Schmalbandes (5) abgeschrägt ausgebildete Enden (7) aufweisen.
摘要:
A hose assembly (100) for use underwater or in a wet or severe environment is provided. The hose assembly includes a hose (30) having an interior space (33) and extending in a longitudinal direction. A first termination assembly (50) terminates the hose at a first end (31) and a second termination assembly (60) terminates the hose at a second end (32). A signal carrier (10) is disposed in the interior space of the hose and extends between the first and second termination assemblies. A strength member (20) is disposed in the interior space of the hose.

Es wird eine Fluidleitung (1) angegeben mit einem Rohr (2) aus einem Kunststoffmaterial. Man möchte bei der Führung der Fluidleitung (1) flexibel sein. Hierzu ist vorgesehen, dass das Kunststoffmaterial mit einer Temperatur von mindestens 150°C belastbar ist und das Rohr (2) auf einem Teil seiner Länge von einem Dehnschutz (8) umgeben ist.
摘要:
An extensible hose, comprising an inner tubular element (2) suitable, in use, for being passed through by a fluid, said inner tubular element (2) being made from a first elastically extensible material and suitable for lengthening and widening under the action of the pressure of the fluid. The hose (1) also comprises at least one extensible outer tubular element (3) overlying, and coaxial to, said inner tubular element (2), comprising at least one surface portion (4) made from a second material resistant to external stresses, and the like.
摘要:
Safety hoses protected by wire mesh and an apparatus for manufacturing them are disclosed. The hose assembly has an inner flexible tube, wrapped with two helices made of ribbons of woven, wire mesh. An outer flexible tube is fitted over the helixes. The ribbon is woven from metal fibers having a diameter of less than 0.20 mm and open apertures of less than 0.45 mm. The ribbon is preferably made of bias-cut material and the pitch of the helixes is such that the warp threads of the ribbons overlap at an angle between 15 and 33 degrees. Alternately the hose may be ribbon braided, having two or more ribbons of woven wire mesh braided together over the inner tube. A modified "May pole" braiding machine to accomplish such ribbon braiding is disclosed.
