The concentricity of pipe avoids keeping the temperature intermediate rigid polyurethane foam because radial deflection occurs in working steel tube elongation process
The uniformity of layer damages, and reaches optimization polyurethane thermal pipe product structure, extends the purpose of working life.
To achieve the above object, the utility model adopts the following technical solution：
A kind of polyurethane thermal pipe with interior slippage bracket, including the working steel tube, the poly- ammonia that set gradually from inside to outside
Ester insulating layer and outer protection tube；It is particular in that, slippage bracket in one group is arranged between the working steel tube and outer protection tube
With asbestos insulation pad；The asbestos insulation pad is symmetrically arranged two c-types slips structure, is installed on the outer wall of working steel tube
On；The interior slippage bracket is made of fixed seat, idler wheel, roller shaft and idler wheel bracing strut, and the fixed seat is split type annulus
Clip is fixedly clamped by bolt assembly outside asbestos insulation pad, and working steel tube, asbestos insulation pad and fixed seat is made to fix dress
With together, it is circumferentially uniformly arranged one group of idler wheel bracing strut in the outer circle of fixed seat, the roller shaft is hinged with idler wheel bracing strut
Assembly, assembles idler wheel on roller shaft.
The above-mentioned polyurethane thermal pipe with interior slippage bracket, the idler wheel outer surface match outer protection tube interior wall construction, are
The drum type arc surface of centre protrusion.
The above-mentioned polyurethane thermal pipe with interior slippage bracket, axial length dimension are 12 meters, the interior sliding branch
Frame is evenly arranged along its axial direction, and interior slippage bracket quantity is no less than three.
The above-mentioned polyurethane thermal pipe with interior slippage bracket, is arranged at least three idler wheels in each group in slippage bracket
Bracing strut, roller shaft and idler wheel.
The utility model is a kind of polyurethane thermal pipe with interior slippage bracket, is suitable for the conveying of high-temperature steam, it
Slippage bracket and asbestos insulation pad in one group are provided between working steel tube and outer protection tube, when working steel tube expanded by heating,
The idler wheel being evenly arranged in interior slippage bracket is rolled along outer protection tube inner wall, thus generates the guiding of the axial movement to working steel tube
Effect, ensure that the concentricity of working steel tube and outer protection tube, avoid because radial deflection pair occurs in working steel tube elongation process
Intermediate rigid polyurethane foam insulating layer uniformity damages, and has reached optimization polyurethane thermal pipe product structure, has prolonged
The purpose of its long working life.
