Definitions

  • the present invention relates to an insulated pipe or piping system with an annular end cap and an elastic, non-metallic cladding element annular end cap.
  • the endcap forms a gasket and spacer for cladding on tubular systems with cladding.
  • Pipes and pipe systems are frequently used in the process industry, on offshore and onshore oil and gas facilities etc.
  • Pipe systems include straight sections, pipe bends, T-joints, elbows, diameter reducers, flange connections, valves,
  • Such systems must in many cases be insulated for a number of reasons including reducing heat loss, providing an external surface with safe temperatures, reducing heat accumulation in cold systems, reducing transmitted noise, improving fire resistance in the event of a fire etc.
  • Many systems are also designed for a long lifespan, perhaps up to 70 years or more, making it particularly important to prevent corrosion by preventing moisture for instance from condensation or precipitation from entering into the insulation.
  • Insulation tends to accumulate moisture, and thus present an increased risk of rust/corrosion on the covered pipe or elements attached to the pipe such as valves, flanges, attachment brackets, diameter reducers and so on. Moisture can also affect the insulating properties negatively, may result in premature
  • Cladding elements for insulated pipe systems of the above described type are typically installed using pop rivets and / or self-tapping screws or metal bands to align the drilled holes.
  • DE20218097 describes a pipe passage for a pipe with a pipe insulation shrouding within a mantle, having a closure as an end disk.
  • the disk is separated from the pipe surface by a closure profile of an elastic material.
  • the pipe passes through the disk opening.
  • An example of a new and more efficient insulating material include insulating materials derived from aerogel such as a mat sold under the trade name of Pyrogel XT-E. Pyrogel XT-E mats are typically 10mm thick or less as greater thicknesses become difficult bend and form into shape, and greater thicknesses are in most situations superfluous.
  • Pop rivets and screws also have the potential of beginning to leak over time even if sealing compounds are used, and it is an object of the present invention to provide a system where this additional risk is eliminated.
  • Pop rivets and screws may also induce high stresses in the area of the pop rivet or screw, in particular in off design conditions, and it is an object of the present invention to eliminate such high stresses that potentially can cause leaking and in extreme cases tearing of the cladding material or shearing / stripping of the pop rivet or screw.
  • Off design conditions may typically result from impacts with foreign objects such as vehicles, cranes etc.
  • a sealing compound is normally used to form a joint seal and to provide redundancy in the sealing of the joints. It is also a purpose of the present invention to provide cladding elements with a sufficient integrity and rigidity to be self-supporting. The cladding elements are thus independent of the underlying structure and will not expose the underlying structure to pressure against the insulation.
  • the cladding elements and end cap of the invention can be installed around a pipe system without being thread onto the pipes from an end. It is also a purpose of the present invention to provide a cladding element and an end cap gasket that can be designed with joints and seams that will guide liquids from the top to the bottom of the cladding elements without seeping to the inside of the cladding elements.
  • the present invention includes an insulated pipe or piping system with a pipe covered by at least one layer of insulation on top of a surface to be protected comprising.

  • the at least one layer of insulation may be equal to or less than 10mm.
  • the at least one layer of insulation may be equal to or less than 5mm.
  • the present invention concerns a sheet metal cladding element with a substantially circular cross section, where the sheet metal cladding element defines a circumference.

At least one band surrounds the first sheet metal cladding element.
  • An elastic, non-metallic, annular end cap with a rectangular cross section has a thickness T1 of at least 15mm and at least one slit extending from an outside of the annular end cap to an inside of the annular end cap.
  • the annular end cap is located and forms a sealing spacer between the insulation covered pipe and the first sheet metal cladding element at the first end portion.
  • a bead may extend along a circumference of the sheet metal cladding element surrounding the first end portion.
  • the rectangular cross section has a ratio of height (D1 -D2) to thickness T1 of less than 6: 1 .
  • the at least one band surrounding the first sheet metal cladding element may also surround the end cap, holding the cladding element between the end cap and the band.
  • a front face of the end cap may extends past an edge of the cladding element.
  • the end cap may be made of a silicone material.
  • the end cap may be made of polydimethylsiloxane with vinyl groups, fillers and pigments.

  • the insulation material can be mat of Pyrogel XT-E. Pyrogel is a trademark for insulating material made of aerogel in fibres.
  • the insulating material is held onto the pipe 3 with tape.
  • a condensation barrier foil 7 surrounds a second insulation layer to prevent condensation from building up and cause humidity in the insulation material.
  • An outer insulation layer is located between the condensation barrier foil 7 and straight outer cladding 2 of 0.5mm acid-proof stainless steel, held in place by acid- proof stainless steel attachment bands 5.

  • the cladding elements 2 include a seam to allow the cladding elements 2 to be installed over a pipe on an existing assembled pipe system.
  • a longitudinal bead may extend along the seam.
  • the circumferential bead 6 of the cladding element 2 provides a stop element for a neighbouring cladding element, serves to maintain the shape of the cladding element 2 and to provide a guide for the overlapping area of the cladding element 2 preventing misalignment of edges of the cladding element 2.
  • the circumferential bead 6 is typically made with a beading tool / bead roller or a crimping machine. A suitable sealing compound can be applied to the overlapping area.
  • circumferential bead also serves to locate a steel band 5, ensuring that the band not is moved away from the cladding element and that the band is located in perfect alignment with the cladding without being inclined. An inclined assembly of the band will potentially result in an insufficient tightening of the band.
  • the circle marked detail A is a cross section of the end cap gasket and spacer 1 in detail.
  • a front face 8 of the gasket 1 extends beyond a front face or edge 9 of the cladding element 2.

  • the silicone rubber material of the end cap gasket 1 is also sufficiently rigid to maintain the shape of the cladding 2 in shape and to form a spacer or distance piece between the cladding 2 and the tubular 3.
  • the end cap gasket 1 prevents the cladding 2 from collapsing under the tension from the metal band 5.
  • the bead 6 increases the strength and deformation resistance of the cladding element at the end and reduces the risk of denting of the end of the cladding element. Denting the end of the cladding element may result in leaks between the cladding element 2 and the end cap gasket 1.
  • a radial slit may be cut in the end cap gasket to allow the gasket 1 to be slid over the pipe 3 without any access to the end of the pipe.

  • Fig. 2 shows the invention in perspective view where the end cap gasket 1 surrounds the pipe 3, and forms a spacer between the pipe 3 and the cladding 2.
  • the reinforcing bead 6 prevents the metal bands 5 from sliding off the cladding 2 and increases the stiffness of the cladding to prevent buckling of the cladding 2.
  • the reinforcing bead 6 also provides a guide for the cladding 2 in the overlapping portion of the cladding 2 to ensure that the overlapping portions of the cladding are aligned. This is achieved as the bead on the upper side of the lower portion of the overlap extends into the bead on the underside of the upper portion of the overlap.

It is essential that the thickness T1 of the end cap gasket 1 and thus rigidity is sufficient to allow the end cap gasket 1 to act both as a spacer between a pipe and a cladding and to absorb mechanical pressure from the cladding onto the end cap gasket without any additional elements.
  • the end cap gasket must also be sufficiently flexible to allow the gasket to be opened and installed onto a pipe.
  • the slit must in other words allow the gasket to be opened at least an amount corresponding to D2 to enable the gasket to be installed onto the pipe.
