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 end cap may be made is made of a silicone material.
- the end cap may be made of polydimethylsiloxane with vinyl groups, fillers and pigments.
- Fig. 1 shows steel pipe or tubular with a cladding and an insulating system of the invention
- Fig. 2 shows the invention in perspective view
- Fig. 3 is a front view of an end cap gasket
- Fig. 4 shows an end cap gasket installed around a pipe with a cable running along the pipe in perspective view
- Fig. 5 is perspective view of an end cap gasket with an outer diameter D1 , an inner diameter D2 and a thickness T1 .
- Fig. 1 is a cross section and a detail of a steel pipe or tubular 3 with a cladding 2, insulation 4 and a seal or end cap gasket 1 in the form of a flexible spacer of the invention.
- the pipe 3 is insulated by layers of insulation 4.
- 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.
- End cap gasket 1 seals around the pipe 3 to prevent ingress of water / liquid into the insulation 4 from the end of the cladding and forms a spacer between the cladding 2 and the pipe 3.
- a flange is located at the
- Each cladding element 2 has a substantially circular cross section and a bead 6 along the circumference.
- the bead 6 is a reinforcement increasing the rigidity of each cladding element 2 and forms a stopping element for ensuring that the joint with the neighbouring element is located correctly.
- the bead also and ensures that the edges of the longitudinal seam are aligned with each other to ensure that the cladding element 2 maintains it intended shape.
- circumference of the two left cladding elements provides a suitable seat for the metal band 5 holding the cladding elements together.
- the bead 6 also ensures that the metal band 5 is correctly aligned and remains on the intended location on the cladding elements.
- 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.
- 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 metal band 5 extends somewhat over the end cap gasket 1 to reduce the stress on the cladding element 2.
- 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.
- a sealing compound such as a sealing compound under the trade name Nitoseal SC30 can be used to seal the slit and the transition between the end cap gasket 1 , the cladding 2 and the pipe 3.
- 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.
- Fig. 3 shows an end cap gasket 1 in the form of a spacer with a front face 8 and an inner face 12 towards a centre of the end cap gasket 1 and an outer face 13 along a circumference of the end cap gasket 1 .
- a cut out 10 provides a space for a cable on the outside of a pipe and a slit 1 1 enables the end cap gasket 1 to be installed onto a pipe without accessing the end.
- Fig. 5 shows an end cap gasket 1 with an outer diameter D1 , an inner diameter D2 and a thickness T1 .
- the thickness T1 is typically 19mm.
- the diameter D2 depends on the diameter of the pipe to be covered and the diameter D1 depends on the diameter D2 of the pipe to be covered and the thickness of the insulation or the diameter of the cladding. 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.
- the band 5 is described as a metal band.
- Such bands are well known within the art and are tightened with a well known tightening tool and locked in a tightened position with a metal buckle.
- Other types of bands, band materials buckles and tightening mechanisms may however be used without departing from the present invention.
