Definitions
- the present invention relates to a method and an attachment device for attaching insulation material which, preferably in the form of insulation units such as mats, is placed insulat- ingly around the outside of pipelines which e.g. may be of the kind included in ventilation plants.
- GB patent application No. 2,255,818 deals with an insulated pipeline, in which the entire insulation layer is encapsu- lated within a metal jacket.
- GB patent specification No. 1,593,255 deals with a method for covering insulated/metal coated joints between cylindrical sections.
- This external clothing/ insulation is covered by panels encapsulating the clothing and overlapping each other.
- overlapping end edge portions of the panels can be fixed directly to each other without exhibiting a large force accommodating/transferring ability.
- stretchable, lockable bands have been disposed around each overlapping place for the panels (which are not insulation mats, but has the task of covering a probably adhering insulation layer on the outside of the tubular or similar sections) disposed.
- the respective attachment band is tensioned evenly around adjacent insulation end portions at each joint space in the insulation, the tension- ing also being able to cause a simultaneous locking of the respective attachment band in tensioned condition, or that the attachment bands may be subjected to a locking operation subsequently to the tensioning.
- the attachment band or each attachment band half may be formed with a central, inwardly projecting bead orientating itself such in said space that the attach- ment band easily centralises laterally.
- a bead may be
- This centring or positional fixing, continuous bead may, possibly, be deleted if the band, at that side which come rest against the opposing insulation face, is provided with projections in the form of spikes.
- Such spikes are particularly efficient when used with insulation kept in place by means of an external net having small meshes, the spikes engaging positionally fixingly into the meshes of the net.
- the spikes may be formed through punching triangular attachment band material configurations in the form of slop- ingly projecting, pointed spike-like portions of the attachment band.
- Figure 1 shows a fragmentary longitudinal view through the wall of an externally insulated pipeline, the insulation mats thereof at the respective joint space being firmly connected to the pipeline by means of an attachment band;
- Figure 2 shows a lateral section through pipeline, insulation and a divided attachment band according to the invention
- Figure 3 shows a divided attachment band fastened to a pipeline
- Figure 4 corresponds to figure 3, but here the attachment band is shown from the opposite side, where one free band end carries two projecting, plastically defor able lips passed through holes in the other free band end as well as bent lockingly over, so that the tongues extend almost parallel to the band face in the locking position;
- Figure 5 corresponds to figure 4, but illustrates an embodiment-comprising punched out spikes as well as a centring circular bead;
- Figure 6 shows a plurality of attachment bands fixed around a band where the central portion is shown in axial section;
- Figure 7 shows a laterally angled attachment band to be placed at the joint place for a branch pipe
- Figure 8 shows a cross-section along the line VIII -VIII in figure 7.
- Reference numeral 10 denotes a pipeline intended to be included in e.g. a ventilation plant or a pipe plant for water.
- the pipe line 10 is provided with insulation units 12 and 12', e.g. in the form of insulation mats which, at least externally in relation to the pipeline 10, may have a foil layer 14, 14', in order to keep the insulation material proper better together.
- insulation units 12 and 12' e.g. in the form of insulation mats which, at least externally in relation to the pipeline 10, may have a foil layer 14, 14', in order to keep the insulation material proper better together.
- it may also be used shape-durable insulation where two opposing insulation halves surround the pipe.
- FIG. 1 shows an attachment band 18 according to the invention which has been laid around adjacent end portions of neighbouring insulation mats, and that the end portions, thus, are clamped somewhat together in the radial direction of the pipeline 10; this being due to the tensioning of the attachment band 18.
- figure 1 shows an inwardly directed bead-shaped centring projection 20 which, upon the mounting and tightening of the attachment band 18 will seek to orientate itself within the space 16 of jointing between two neighbouring in- sulation end portions and, thus, centre the attachment band laterally.
- This bead-shaped centring projection 20 may consist of a circu ferentially extending, continuous bead or of bead portions disposed in mutually equal distances or similar projecting means.
- Figure 2 which is a cross-sectional view along the section plan line II - II in figure 1, shows an attachment band design consisting of two approximately 180° semi-circular attachment band parts 18a, 18b, both having the same width and the same central bead design 20.
- the two attachment band halves 18a, 18b overlap each other at both adjacent end portions and are, at one overlapped end area, interconnected by means of screws 22, which exclusively have a connecting function; also see figure 3.
- plastically deformable lips 24 on a radially seen innermost end portion 18b' of the attachment band half 18b have been passed through through-going holes 24' in the radially seen outermost end portion 18a 1 of the attachment band half 18a.
- the longitudinal proportion is such that when the major part of the plastically deformable lips 24 on the attachment band half 18b have been pulled through said through-going holes in the attachment band half 18a, the joined attachment band halves 18a, 18b will be appropriately tightened around a standard insulation mat laid around a pipeline 10 having a given diameter, so that when the lips 24 are folded down about 90° from the piercing position an adequate tensioning is established in the attachment band 18; 18a, 18b.
- the attachment band will be capable of being tightened and, thereupon, locked by means of a screw connection or in another known way.
- FIGS 5 - 8 show an embodiment characterised in band ate- rial punchings in the form of triangular spikes 26 projecting slopingly out from the attachment band face opposing the outer insulation side face.
- Each of these spikes 26 may have a narrow triangular circumferential shape tapering toward the free end and being connected to the remaining attachment band body at the opposite, broad end, and where each of the triangular spikes 26 normally will form a right angle with adjacent attachment band face facing the outer face of the insulation.
- an ex- ternal net (not shown) having small meshes and adapted to retain the insulation is used.
- Spikes 26 on the inner side of the attachment band are especially advantageous in connection with such fixing nets, as the spikes 26 will engage positional-fixingly into the small net meshes, so that the centring means 20, possibly, may be deleted.
- Attachment bands 18 having spikes 26 may also be used on the previously described insulation 12, 12' which, outermost, is provided with a foil layer 14, 14 ' .
- an attachment band according to the invention is used to retain the insulation in position around a bend zone.
- the composite bend may be formed on the basis of an adequately large radius of curvature or, as indicated in figure 6, through successive angulations.
- each attachment band 18 see the attachment band extending around the joint 16A, has side faces parallel to the angled portion of the insulation 12, 12' surrounded by the band 18.
- this special attachment band 18 has a right- angled cross-section, the band ends be- ing twisted and made flat downwardly toward opposite fastening points 28, simultaneously as the attachment band portions all the time rest supportingly and retainingly against the external insulation face (mesh net face) around branch pipe IOC and pipeline 10D in the jointing area.
