Definitions

  • ABSTRACT An axially extensible and contractable reflective thermal insulative structure is disclosed, comprised of two telescoping sections, each containing a plurality of reflective metal sheets, adjacent pairs of sheets are dis posed such that telescoping motion is permitted while simultaneously proper spacing of the sheets is maintained.
  • the insulation unit may be flat or curved.
  • a restraining means controls the telescoping motion while preventing unintentional disassembly of the unit.
  • the sheets are separated from each other and from the shells by various types of spacing means, all of which are designed to provide minimum contact and thus minimum area for conductive heat flow.
  • spacer means include slotted brackets and cone-shaped stand-offs.
  • the sheets are generally polished to provide maximum reflectivity.
  • the allrnetallic reflective insulations differ substantially from the conventional thermal insulation which comprises blocks of refractory or low-conductivity material, generally ceramics or low-conductivity masses of fibrous materials such as glass fibers or mineral wool.
  • the metallic sheet configuration of the reflective insulation provides a much stronger insulation structure than is found with the brittle ceramic blocks or the fragile fibrous structures.
  • the open structure of the reflective insulation permits easy cleaning of the interior of the insulation, a distinct advantage when the insulation is contaminated with corrosive or radioactive liquids due to such accidents as pipe ruptures or vessel leakages.
  • Such advantages, as well as the efficient insulating properties have led to enthusiastic commercial acceptance of reflective insulations, particularly in the nuclear power industry.
  • the fabricated reflective insulation units are delivered to the job site, that the workmen who erected the structure to be insulated deviated slightly from the engineering specifications and drawings in the actual dimensions of the finished structure.
  • the fabricated reflective insulation unit which was constructed to the exact engineering specifications, thus does not properly fit on the actual structure in the field.
  • the engineering drawing might call for a section of pipe to be 36 inches long and the insulation manufacturer, therefore, fabricates a reflective pipe insulation also 36 inches long.
  • the pipefitter who installed the pipe misaligned it slightly, so that its actual measured length is 37 inches.
  • the reflective insulation structure must, therefore, be completely refabricated or modified to compensate for the nonspecification construction.
  • Telescoping structures are also known in the art.
  • the old and conventional assemblage of a single male section slidably fitted within a single female section is shown, e.g., in U.S. Pat. Nos. 219,098; 372,075, and 1,256,654.
  • a solid insulation structure, in which the abutting solid insulation (asbestos) blocks slide apart to expose a reflective surface is shown in U.S. Pat. No. 2,742,384.
  • the invention herein is an extensible reflective thermal insulation structure which is composed of two telescoping sections. Each section contains an inner plate and an outer plate and, spaced therebetween, a plurality of reflective sheets, which sheets are spaced one from another by spacer means cooperating therewith.
  • the outer plate of the first section is slidably positioned inwardly of the outer plate of the second section. Each sheet in one section slidably abuts a corresponding sheet in the other section.
  • Adjacent pairs of sheets in one section have terminal portions positioned between adjacent pairs of sheets in the other section and adjacent pairs cooperate with each other to maintain relative spacing of the reflective sheets.
  • That pair of sheets in the one section which are positioned between the opposite pair of sheets have between them stand-off means positioned adjacent to the telescoping sliding terminal portions.
  • Restraining means are attached to at least the outer plate of the second section to prevent outward expansion of the structure.
  • the restraining means is attached to the inner and outer shells of the second section and passes through the inner and outer plates of the first section and all sheets.
  • the inner and outer shells and the sheets of the first section have means cooperating with the restraining means to permit telescoping movement of the sections relative to each other but yet preventing separation of the two sections.
  • the insulating structure may be flat to insulate wall sections or curved to insulate vessels, pipes and similar curved objects. In a commonly used curved configuration, the insulation assumes a hollow cylindrical shape and is used to insulate lengths of pipe.
  • FIGS. 1 and lb illustrate respectively perspective views of a circular (cylindrical) reflective insulation section in place surrounding a pipe to be insulated and a flat panel structure in place against a flat surface to be insulated.
  • FIG. 2 is an elevation view of the curved structure of FIG. 1, showing in a partial cut-away section the internal telescoping structure of the insulation.
  • F IG. 3 is a partial cross-sectional view taken on plane 33 of FIG. 2 showing the arrangement of the reflective sheets and a typical means for maintaining separation between the sheets.
  • FIGS. 4a and 4b are enlarged schematic detailed drawings of the telescoping structure of the insulation, with FIG. 4b additionally illustrating means separating adjacent reflective sheets.
  • FIG. 5 is an exploded view illustrating schematically a means permitting telescoping movement while restraining separation, misalignment, or rotation.
  • FIG. 1 shows a cylindrical pipe insulation 2 disposed surrounding a hot pipe 4 which is to be insulated.
  • the pipe insulation is normally constructed in two semicylindrical sections 6 and 8 and dimensioned with inner and outer diameters such that the sections can be fitted closely around the pipe and then sealed together to form a continuous cylindrical insulating structure. Bands, clamps and other conventional devices (not shown) may be used to secure the cylindrical structure.
  • each semicylindrical structure has attached thereto at each end arcuate end plates such as 10 and 12 respectively.
  • Such end plates of a section serve to close off the internal space of the structure and to provide support means to maintain the cylindrical shape and to properly position the insulation about the pipe.
  • the outer shells of the two semicylindrical halves are conventionally extended slightly, as shown at 7 and 9, to provide an overlap covering the joint between the halves.
  • FIG. 1b shows a flat reflective insulation structure 14 positioned to insulate a hot flat surface 4.
  • This structure contains rigid sidewalls such as 16, a top (or outer plate) 18 and a bottom (or inner plate) 20. This structure is mounted in place on the surface to be insulated by clamps, bands or other means.
  • each of the structures Disposed within each of the structures is a plurality of reflective metal plates generally designated 22.
  • the number of plates, their spacing and the total thickness of the insulation will be determined by the hot side temperature and the amount of temperature drop to be obtained.
  • the sheets are polished and are separated one from another by separation means such as the coneshaped projections or stand-offs 24. Such projections are shown in greater detail in aforesaid US. Pat. No. 3,190,412. Where there are no end plates, as in the flat structure 14, flange 26 and/or strap 28 may be used to restrain the reflective sheets and prevent them from coming out of the outer framework.
  • each insulation structure is divided into two sections, a first or female section 30 and a second or male section 32.
  • each semicylindrical portion of the pipe insulation shall be considered as a separate structure.
  • These sections are constructed such that the outer shell or plate 34 of second section 32 slidably engages the outer shell or plate 36 of first section 30 and is disposed inwardly thereof.
  • Inner shell or plate 38 of second section 32 is similarly slidably engaged with inner shell or plate 40 of first section 30 and generally also lies inwardly thereof.
  • Each of sections 30 and 32 contains its own set of reflective insulation sheets 22 or 22 respectively. These are essentially longitudinally co-extensive with the inner and outer shells of the section. Normally, each individual sheet overlaps with and slidably engages a corresponding sheet of the other section, as is shown in detail inFlGS. 4a and 4b. (It is possible to design a structure wherein one section contains more reflective sheets than does the other section, and therefore some of the excess sheets may not be in slidable relationship to sheets of the former section. However, no technical advantage is gained by such an arrangement and since it merely increases the complexity of the structure unduly, this arrangement is not preferred.)
  • FIGS. 4a and 4b show in partial section a portion of sections 30 and 32.
  • FIG. 4a four pairs of corresponding plates or sheets, designated respectively 42a and 42b, 44a and 44b, 46a and 46b and 48a and 48b are shown.
  • FIG. 4b portions of many of the same sheets are shown, and also portions of the outer shells 34 and 36 of respectively sections 32 and 30 are shown.
  • Each of the pairs of sheets 42(1-42b, 48a48b slidably engage each other and can move freely in a longitudinal direction. Rotative or lateral movement is prevented by the strap 28 of the flat structure or an equivalent component in the cylindrical structure (not shown; but see, e.g., aforesaid US. Pat. No. 2,84l,203). Rotation and lateral movement will also be prevented by the preferred nut-and-bolt restraining means described below. The direction of telescoping motion is indicated by the large arrow between FIGS. 4a and 4b. Nut and bolt 43, or similar restraining means passing entirely through the slotted sheets and plates of section 32, retains those sheets in fixed relationship to each other longitudinally, and permits section 32 to telescope as a unit relative to section 30.
  • the novel structural design of this invention also acts simultaneously to maintain the proper spacing between the adjacent sheets of reflec tive insulation.
  • Each sequential pair of sheets in a single section is sandwiched between a pair of sheets from the other section.
  • the tendency of each pair of sheets to spread apart is thus counteracted by an equal and opposite spreading tendency of adjacent pairs from the other section and the equally opposed forces thus act to maintain the desired spacing of the respective sheets.
  • FIGS. 4a and 4b illustrates the pairs A and B of section 30, comprising respectively sheets 42a-44a and 4611-4811.
  • pair C comprising sheets 44b and 46b is disposed or sandwiched between sheets 44a and 46a of pair X of section 30.
  • restraining means may comprise, e.g., an inelastic band strapped around the outer shell of section 30 in the cylindrical configuration 2 or fixed brackets restraining top 18 of the flat configuration 14.
  • rod member 50 passes entirely through all plates and sheets and is secured on the inner and outer surfaces of the insulation to limit expansion. In a typical embodiment of this preferred structure, illustrated in FIGS.
  • bolt 56 projects entirely through the inner and outer shells and all sheets of both sections.
  • a relatively thin, flat head 58 on bolt 56 engages the inner shell 40 or bottom 20 of first section 30 and is fixedly attached to the structure by threading or sliding nut 60 onto the opposite end of bolt 56 to engage the outer shell 36 or top 18 of section 30 (with washer 62 normally being placed between nut 60 and the surface of outer shell 36 and top 18).
  • Clearance for bolt head 58 between inner shell 40 or bottom 20 of section 30 and the outer surface of pipe 4 or wall 4' can, be obtained by the use of stand-off 64; such a structure is shown in US. Pat. No. 3,648,734.
  • An equivalent result is obtained by use of an unthreaded rod and speed nut in place of the threaded bolt and nut described above.
  • a semicylindrical pipe covering intended to insulate 10-inch nominal diameter steel pipe was designed to a nominal length of 36 inches.
  • Each of sections 30 and 32 was designed to a length of 20 inches, thus providing a 4-inch overlap.
  • Two-inch slots in the inner and outer shells and all sheets of section 32 were designed in the longitudinal center of the 4-inch overlap area; the two slots were circumferentially spaced apart, being disposed generally at opposite sides of the semicylindrical structure, approximately as shown in FIG. 5.
  • Corresponding bolt clearance holes were designed in the inner and outer shells and all sheets of first section 30, also in the longitudinal center of the overlap area. This arrangement provided for a 2-inch adjustment in the overall length of the structure, for an actual adjustable size of 36 i 1 inch.
  • FIG. 4b A preferred arrangement of the sheets is shown in FIG. 4b.
  • the separating means such as cones 24a, 24b, 24y, and 24z which separate the adjacent pairs, are placed such'that the spacer means in those pairs of plates (e.g., A, B, Y and Z) which are disposed between the next adjacent pairs, are placed closer to the end extremities of sections 30 and 32 than are those spacers (cones 24c and 24x) which separate the other pairs of sheets (such as C and X).
  • the structures herein can be constructed of a number of different types of metals or alloys.
  • the particular material chosen will be determined by the temperatures to be encountered, the desired strength of the structure, service life, customer requirements, corrosion resistance requirements and cost, among other things.
  • Typical materials which may be used include steel, titanium and aluminum sheets, with a preferred material being stainless steel. Surfaces of the sheets and shells may be and generally are polished to enhance the reflectivity.
  • An extensible reflective metallic thermal insulation structure comprising:
  • each of said sections comprising an inner plate an an outer plate and disposed therebetween a plurality of reflective sheets, said sheets being separated one from another by spacer means;
  • each of said sheets in one of said sections slidably abutting a corresponding plate in the other of said sections;
  • each sequential pair of sheets of one section being disposed between sequential pairs of sheets of said other section
  • restraining means cooperating with said outer plate of said second section to restrict the outward movement thereof; whereby said sections can telescopically move relative to each other while simultaneously maintaining proper spacing of the sheets in each section.
  • said restraining means comprises a rod member passing through all of said plates and sheets and secured on the inner and outer surfaces of said structure.
  • each plate and sheet of said first section has therein a longitudinal slot and each plate and sheet of said second section has therein a clearance hole, all holes and slots being :aligned, and said rod member passes through said slots and holes.
