Flexible pipe is particularly useful in connecting a sub-sea location to a sea level location. A flexible pipe allows a pipe to bend and is especially useful for connections in small, tight & awkward spaces. Wellstream is highly specialized in the fastest growing segment of the O&G services market – deepwater. 1 illustrates a flexible pipe body;continually pulling fibres through the die.In the drawings like reference numerals refer to like parts.According to a second aspect of the disclosed technology there is provided a method of manufacturing flexible pipe body, comprising the steps of:The present application is a divisional of U.S. application Ser. The cross sectional profile of the wound tapes which thus prevent the pipe from collapsing or bursting as a result of pressure are sometimes called pressure-resistant profiles.In view of the many possible embodiments to which the principles of the disclosed invention may be applied, it should be recognized that the illustrated embodiments are only preferred examples of the invention and should not be taken as limiting the scope of the invention. As flexible pipe applications move into deepwater and ultra deepwater, attention is focused on enhancing service life, particularly with respect to corrosion and wearing. Certain embodiments of the disclosed technology provide an armour layer formed of interlocked windings in which a further composite tape can be wound radially outside the interlocked armour layer. They include static flowlines, dynamic risers, and fluid transfer lines for the transport of hydrocarbon production and injection fluids. 5 illustrates adjacent windings in an armour layer in an interlocked fashion;Outer layers such as tensile armour layers, insulating layers and an outer sheath layer may be thereafter formed.winding at least one armour layer over an internal pressure sheath by winding a tape of composite material over the sheath.According to a third aspect of the disclosed technology there is provided a method of manufacturing a composite tape via a pultrusion process, comprising the steps of:FIG.
Pressure armour layers tend to be wound with a large angle in relation to the longitudinal axis of flexible pipe body and often have a specific cross section profile to interlock so as to be able to maintain and absorb radial forces resulting from outer or inner pressure on the pipe. 3 illustrates a cross section of tape used to form an armour layer;Certain embodiments of the disclosed technology provide flexible pipe body in which at least one armour layer over a fluid retaining layer is formed from a wound tape of composite material. Rather, the scope of the invention is defined by the following claims. The primary load on such a layer is tension.
7,946,312, which claims priority to Great Britain Patent Application No. Embodiments of the present invention may be used with any type of riser, such as a freely suspended (free, catenary riser), a riser restrained to some extent (buoys, chains), totally restrained riser or enclosed in a tube (I or J tubes).Throughout the description and claims of this specification, the singular encompasses the plural unless the context otherwise requires. Wellstream Holdings plc is a British company which designs and manufactures flexible pipeline systems for the oil and gas industry. Add to Cart.
