Definitions
- This invention relates to a flexible pipe having multiple layers, one of which is formed with a vent passage for venting gases that permeate through the pipe.
- Fig. 1 is a longitudinal sectional view of a flexible pipe according to an embodiment of the present invention.
- Fig 2 is an end view of the pipe of Fig. 1.
- Fig 3 is a view similar to Fig. 2 but depicting an alternate embodiment of the invention.
- a flexible pipe according to an embodiment of the present invention is shown, in general by the reference numeral 10
- the pipe 10 is formed by an inner layer 12, preferably in the form of an extruded plastic sheath, for conveying fluid through its bore.
- the outer surface of the layer 12 is undulated thus forming a senes of ridges and valleys for reasons to be descnbed.
- the layer 12 may be formed in a conventional manner using polymers, or the like.
- a layer 14 extends around the layer 12 and provides resistance to internal pressure, hydrostatic collapse and crush.
- the layer 14 is formed by helically wrapping a continuous metal st ⁇ p, preferably formed of carbon steel, with adjacent windings being interlocked, to form a flexible layer that provides significant hoop and axial strength.
- the layer 14 is marketed by the assignee of the present invention, Wellstream, Inc., under the "Flexlok" trademark.
- the layer 14 can be of the types disclosed in application serial no. 09/706,070 (attorney's docket no. 27644 03.02) filed concurrently herewith and assigned to the assignee of this application; with the disclosure of the former application being incorporated by reference.
- a layer 16 of wrapped wires extends over the layer 15 and consists of a series of wires 16a helically wrapped around the extenor of the layer 15 to form a first tensile layer, and an additional senes of wires 16b wrapped around the first senes of wires 16a to form a second tensile layer extending over the first tensile layer.
- the wires 16a and 16b may have a circular cross section, and are wound at a relatively high lay angle to provide significant hoop strength and axial strength.
- the wires 16a and 16b are formed by carbon steel with a plastic or anodic coating It is noted that the layer 14 prevents the expansion of the layer 12 into gaps formed between the wires of the tensile layers 16a and 16b.
- a layer 18 is formed by helically wrapping tape over the layer 16.
- the tape forming the layer 18 can be plastic or metal and can be reinforced with glass, metal or a different type of plastic. Although not shown in the drawings, it is understood that the tape layer 18 can also extend between the layer 14 and the layer 16, and between the series of wires 16a and 16b.
- a protective outer layer 20 extends over the tape layer 18 and is preferably in the form of an extruded plastic sheath that extends over the tape layer in a conventional manner, with the tape providing a smooth surface for the extrusion.
- the layer 20 is optional and is required only when the tape layer is inadequate to protect the remaining components of the pipe 10.
- the ndges formed by the undulating outer surface of the layer 12, and the corresponding inner surface of the layer 14, form passages 22 for venting any gases that might permeate through the layer 12. These passages extend for the length of the pipe 10 and can discharge into the ambient environment or atmosphere at one of the ends of the pipe.
- a flexible pipe according to an embodiment of the present invention is shown, in general by the reference numeral 30.
- the pipe 30 is formed by an inner layer 32, preferably in the form of an extruded plastic tubular member, or sheath, for conveying fluid through its bore.
- the layer 32 may be formed in a conventional manner using polymers, or the like.
- a metal stnp layer 34 extends around the layer 32 and provides resistance to internal pressure, hydrostatic collapse and crush. Since the layer 34 is identical to the layer 14 of the embodiment of Fig. 1 and 2, is will not be descnbed in any further detail.
- a seal layer 36 preferably in the form of an extruded plastic sheath, is provided over the layer 34 to increase the resistance to hydrostatic compression, and assist in limiting the moisture that permeates from the bores of the layer 32.
- a layer 38 extends over the layer 36 and consists of a senes of wrapped wires forming two tensile layers. Since the layer 38 is identical to the layer 16 of the embodiment of Fig 1 and 2, is will not be described in any further detail.
- a layer 40 is formed by helically wrapping tape over the layer 38.
- the tape forming the layer 40 can be plastic or metal and can be reinforced with glass, metal or a different type of plastic. Although not shown m the drawing, it is understood that the tape layer 40 can also extend between the layers 32 and 34, between the layers 34 and 36, between the layers 36 and 38, between the layer 38 and 40, and/or between the layers of wrapped wires forming the layer 38.
- a protective outer layer 42 extends over the tape layer 40 and is preferably in the form of an extruded plastic sheath that extends over the tape layer in a conventional manner, with the tape providing a smooth surface for the extrusion
- the layer 42 is optional and is required only when the tape layer 40 is inadequate to protect the remaining components of the pipe 40.
- the undulations of the previous embodiment are eliminated and a plurality of relatively small-diameter tubes 44 are embedded in, and angularly spaced around, the layer 32.
- the tubes 44 are provided with relatively small holes or slits, or are fabricated from a matenal having a relatively high porosity, such as a foam structure, to receive any gases that might permeate through the layer 32 or at least a portion of the layer.
- the tubes 44 extend for the length of the pipe and thus pass any of the latter gases to one or both ends of the pipe 30 for discharge into the ambient environment or atmosphere.
- Each layers 16a and 16b can be formed by one wire rather than by a senes of wires, and only one layer (16a or 16b) can be provided.
- the seal layer 36 can be placed between the seal layers 34 and 38 (as shown and descnbed above), and/or between the layers 38 and 40, and/or between the layers 40 and 42.
- the cross section of the wires 16a and 16b, and the wires forming the layer 38 can be round or rectangular as disclosed in the above cited application.
- an outer layer similar to the layer 14 and 34 can be placed around the sheaths 20 and 42, respectively for added protection.
- the layers 14 and 34 can be eliminated and the layers 16 and 36 can be applied directly over the tubular members, 12 and 32, respectively.
- the layers 15 and 36 can be eliminated and the layers 16 and 38 can be applied directly over the layers 14, and 34 , respectively. It is understood that spatial references, such as “under”, “over”, “between”, “outer”, “inner” and “surrounding” are for the purpose of illustration only and do not limit the specific onentation or location of the layers descnbed above.
