Definitions
- the present invention relates to a flexible pipe, and more specifically to a flexible pipe with integrated end caps.
- Such a flexible pipe which will be referred to hereinafter more simply "flexible”, generally has a fairly low length, rarely exceeding a dozen meters and allowing a flexible connection between fixed equipment.
- Their inner diameter is relatively large, greater than 5 cm, typically between 7 and 11 cm.
- the pressure of the effluents transported may exceed 700 bar (70 MPa) and their temperature exceed 150 ° C.
- These effluents may consist of liquids or gases that can be very corrosive, such as oil, aromatic liquids, water , hydrogen sulphide (H 2 S), or carbon dioxide (CO 2 ).
- Such hoses are likely to be exposed to very different external stresses, such as in particular high radial and axial forces, traction on their ends during assembly, exposure to temperatures that can be between -40 0 C and + 70 0 C, an abrasion against the ground.
- Their lifespan varies according to the applications but it must generally be greater than 10 years, and their method of construction must ensure the safety of people and equipment.
- hoses made up of filamentary reinforcements made of steel and / or synthetic material (especially aramid fibers) incorporated within an elastomeric material; these reinforcements, generally multilayered, are embedded in the elastomer, so that the whole forms an indissociable whole;
- non-bonded structure consisting of layers of steel components ensuring mechanical performance and layers of plastic components sealing, with possibility of relative sliding between these two types of layers.
- filament will conventionally be used to designate a cable, a wire, a fiber, or a wick.
- fiber a cylindrical elementary formation of very small diameter, generally made of synthetic, organic or steel material and most often assembled in the form of a wire or wick;
- wick a long strand and small section, consisting of the meeting of parallel fibers, usually referred to in the field of petroleum industry by the English word “roving”;
- wire a long strand and small diameter consisting of the union of twisted fibers and spun together, usually designated in the field of the oil industry by the English word “yarn”; the term “cable”, a bundle of wires of synthetic material or steel, braided together.
- the object of the invention is to provide a hose having the following characteristics and advantages: a) resistance to high pressures, greater than 700 bar (70 MPa), with a large inside diameter (greater than 50 mm) ; (b) light weight, with a linear mass not exceeding a few kilograms per meter; c) ability to adopt a small radius of curvature; d) a structure with a reinforcement composed of several layers of synthetic filaments having both a very high tensile strength and a maximum elongation limited to about 5%; e) resistance to corrosive environments (H 2 S, CO 2 and water in particular); f) structure that can be manufactured in such a way that its two end-connector ends are inseparable from its main part cylindrical flexible and flexible, so as to preserve the continuity of winding of the fibers of each of the layers; g) structure provided with a mooring system for each sheet at the end caps, this without crimping (which could cause shearing of the filaments); h) adoption of
- the hose according to the invention which makes it possible to meet the requirements mentioned above, comprises a flexible and flexible tubular main part, or body, which is composed of at least two coaxial tubular elements, and which is sealingly connected to each of its two ends to a rigid tubular connector end.
- the two coaxial tubular elements constituting said body consist, from the outside towards the inside, in: a) a pressure vault comprising several plies of thin filaments having a high tensile strength, helically wound and in opposition with a winding angle relative to the generatrices which is constant and substantially equal to 54.7 °, these filaments being incorporated in an elastomer layer; b) an attached plastic sealing layer
- the connector end comprises two coaxial cylindrical sleeves integral with each other, namely: ⁇ ) an inner sleeve whose inner diameter is equal to the outer diameter of the sealing layer, so that the latter s' fit without play in the inner sleeve and is retained at its free end portion by means of a mechanical locking member, the outer diameter of this sleeve being slightly greater than the internal diameter of the pressure vault, the latter surrounding the inner sleeve with a certain degree of tightening and being fixed thereto, while being separated from the sealing layer; ⁇ ) an outer sleeve, or skirt, whose inner diameter is slightly greater than the outer diameter of the pressure vault, this skirt extending axially on the side of the hose body over a greater length than that of the
- the connector end is provided with a pair of annular support elements (rings) of flexible and elastically deformable material and variable profile and disposed at said transient region of the pressure vault, one interposed between the sealing layer and the pressure vault and the other interposed between the pressure vault and the skirt.
- rings annular support elements
- said flexible and flexible tubular main part, or body comprises a third tubular element coaxially surrounding the other two, namely a flexible steel protective carcass, to which said outer sleeve is connected;
- said filaments are made of synthetic material, for example aramid; said end-pieces are provided at their periphery with a set of mooring members positioned in alignment with the filaments, and each sheet comprises a network of uninterrupted filaments connecting the two end-pieces alternately in one direction then in the other, bypassing the said moorings, while hanging on them; said sealing layer is removable and interchangeable;
- said mechanical locking member is a conical clamping ring penetrating into the mouth of the sealing layer
- the annular support element interposed between the sealing layer and the pressure vault has a central zone of maximum thickness, and portions fading progressively on either side of this central zone, with a thickness decreasing outward and inward;
- the annular support member is supported by its tapered portion located on the tip end against the inner wall of complementary profile, the free end portion of said inner sleeve;
- the tapered portion located on the body side of the annular support member is axially facing the end portion of complementary profile, substantially conical, the other annular support member interposed between the pressure vault and the skirt ;
- the annular support member interposed between the pressure vault and the skirt is an end bead of a membrane of elastomeric material forming an integral part of the pressure vault;
- each of the plies of filaments which make up the pressure vault is therefore advantageously of the "continuous" type, formed of a single filament helically wound back and forth between the two ends of the hose, and passing around it.
- moorings are for example pins integral with the end cap, according to an arrangement known from WO 2007/112785 in the name of the applicant, a document which can be referred to if necessary.
- pins are here arranged at the periphery of the inner sleeve.
- the retention of the end portion of the pressure vault around this inner sleeve is advantageously supported by the presence of a curable resin which is cast in the annular gap separating the latter from the outer sleeve; the end portion of the pressure vault is thus embedded and retained within the resin.
- the sealed connection of the body of the hose with the end connector end pieces is obtained by the fact that the angle of winding of the filaments with respect to the generatrices at the of these tips is greater than 54.7 °, and advantageously between 56 ° and 65 °, so that, under the effect of an internal pressure prevailing in the pipe, the traction generated on the filaments tends to tighten the sheets on the sealing sheath and on said end caps.
- a constant angulation of the winding substantially equal to 54.7 ° with respect to the generatrices, can be maintained over the entire length of the hose, including included in the end caps, which solves this problem of density and, in addition, facilitates the manufacturing process of the product.
- FIG. 1 is a partial view, in axial section, of an end portion of a flexible pipe according to the invention, represented at the level of an end connector end, this pipe being not subjected to high internal pressure.
- Figure 2 is a view similar to that of Figure 1, the pipe being subjected to radial expansion under the effect of an internal fluid pressure;
- Figure 3 is a partial view, on a larger scale, similar to that of Figure 2.
- Figure 1 is designated by the references PP and EC respectively, the body of the hose - partially visible - and one of its end caps (left end). A similar assembly is naturally provided at the other end of the pipe for the right nozzle.
- Each end has an end portion 100 adapted to be connected to the similar end of an adjacent hose, by a sealed connection of known type, for example by screwing.
- the hose body PP has a cylindrical wall 1 of axis XX 'with a multilayer structure comprising, from the outside towards the inside, a protective carcass of steel Id, a pressure vault Ib-Ic, and a sealing layer reported the.
- the pressure vault is in contact by its inner face with the outer face of the sealing layer. On the other hand, it is separated from the carcass Id, of larger diameter, which surrounds it.
- the pressure vault Ib-Ic comprises a core of elastomeric material inside which are incorporated several plies of thin filaments 10 having a high tensile strength.
- the sealing layer is, for example, of flexible and elastically deformable material, for example plastic or elastomeric material, the quality of which is chosen to resist mechanically, thermally and chemically the attacks of the fluid to be conveyed in the pipe, and 'to the different constraints related to the application in question, while ensuring a perfect seal.
- the connector connector EC also centered on X-X ', consists of parts made of rigid material, for example steel.
- the inner sleeve 2 has an enlarged free end 20 of larger diameter in which the end portion 100 is inserted and screwed.
- This wider end portion 20 with the remainder of the sleeve 2 is through an intermediate zone with a conical wall.
- the sealing layer penetrates it completely, coaxially, inside the main part of the sleeve 2, to this intermediate zone; the inner face of the latter serves as a seat at the mouth Ea of the sealing layer la.
- This mouth also takes a conical shape and is applied against its seat by a locking ring 4 conically complementary face. It is solicited by an intermediate ring 3 itself requested by the screwed element 100 so as to ensure a certain tightening of the mouthpiece Ea between its seat and the ring 4 and ensure a good seal at this level.
- Ad-hoc seals are also provided to seal the connections between the elements 100, 3 and 20.
- the latter have a central opening of circular section and axis X-X ', which the diameter is equal to the inside diameter C 0 of the sealing layer 1a when the hose is at rest (not inflated).
- the outer diameter of the inner sleeve 2 is slightly greater than the inner diameter of the pressure vault Ib-Ic; it is fitted on the inner sleeve with a certain degree of tightening; at this level, it is therefore separated from the sealing layer 1a, the wall of the main part of the inner sleeve 2 being sandwiched between the pressure vault and the sealing layer.
- the sleeve 2 is provided with a plurality of pins 21 arranged radially according to a circumference, towards the outside of the wall. These pins are used for docking constituent filaments of each sheet, which bypass the pins, in a similar arrangement to that described and represented in WO 2007/112785.
- the inner end zone (on the right of the figures) is connected via a ferrule 71 to the free end portion of the carcass Id. These connections are made by gluing, for example.
- this resin 9 covers the end portion of the pressure vault as well as the pins 21 and the filaments 10 which circumvent them.
- the connector end EC is provided with a pair of annular support elements -or rings-5, 6 of flexible material and elastically deformable and variable profile.
- One of these elements, referenced 5 has an approximately biconical outer shape, having a central zone of larger diameter, whose thickness corresponds substantially to the thickness of the inner sleeve 2. It has a central cylindrical opening whose diameter is equal to the outer diameter of the sealing layer la, which passes through it.
- the element 5 is interposed between the sealing layer 1a and the pressure vault Ib-Ic, and adjoins the mouth of the inner sleeve 2. More specifically, the inner wall 23 of the mouth of the sleeve 2 has a profile substantially conical complementary to the outer portion (end-side EC) of the element 5. Its inner portion (body side PP) has a conical portion which bears against the inner wall of the pressure vault, in the transient zone of diameter change of this pressure vault.
- the other element 6 is an end bead of a membrane Ic forming the outer layer of the pressure vault. Its outside diameter is equal to the inside diameter of the skirt 7.
- the element 6 is fitted into the internal entry portion (body side PP) of this skirt. Its central opening flares out from the external side (end-piece EC) to affect a substantially conical profile, complementary to that of the transient zone of diameter change of the pressure vault Ib. Thus this transitional zone is interposed between the two elements. flexible and elastic inside 5 and outside 6.
- the external protective carcass Id non-expandable, does not thwart this expansion because its inside diameter is substantially larger than the outside diameter of the pressure vault.
- the inside diameter of the sealing layer changes to a value Di> D 0 .
- This increase in diameter implies an elongation of the filaments 10 (which can be indicative of up to 5%), but without variation in their winding angle.
- connection of the EC end connector ferrules to the PP hose body is done without crimping.
- the skirt 7 ensures only a resumption of the radial forces, but not the axial retention of the body in the tip, this retention being ensured by the joining of the plies of filaments with each endpiece.
- the number and the dimensions of the pins 21 are naturally chosen according to the characteristics required for the pipe, and in particular the diameter of the filaments and the number of layers used.
- the mooring members are not necessarily pins, nor fortiori cylindrical fingers; they could consist for example of hooks, teeth and / or slots, in particular. Instead of a single set of pins (or similar moorings) disposed in the same transverse plane, it would naturally be possible to provide several similar sets, for example two or three sets slightly offset in the axial direction.
- the filaments may have a circular section, but this is not mandatory.
- Suitable materials include synthetic materials, including aramid, but also carbon, glass and steel.
- the filaments must be sufficiently thin and flexible to be able to get around the mooring members, pins or others.
