Abstract
The utility model relates to a thermal-insulating pipe with supporting plates, which is composed of a work steel pipe, a supporting plate, a reinforcing rib plate, a steel sleeve, a thermal-insulating layer, a moisture discharging pipe and a preset welding section, and the utility model can be used for buried high temperature thermal insulating pipelines. The utility model has the advantages of good thermal-insulating, sealing and protective performance and can prevent the expansion of leak pipe sections, and the utility model can be preset in factories and can simplify site operation.
Description
The utility model relates to the thermal insulation pipe of the band dunnage that a kind of soak pipeline uses.
Existing direct-burried soak pipeline adopts reinforced concrete knoll support tube road, and its deficiency is that reinforced concrete directly contacts the bigger cold bridge of formation with working steel tube, and underground water influences heat insulation effect easily in concrete is penetrated into the thermal insulation layer of insulation pipe.
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art and the thermal insulation pipe that provides a kind of and be used to bury ground soak pipeline, have the band dunnage of good heat insulation, water-tight performance, easy construction.
The purpose of this utility model can reach by following measure.
The thermal insulation pipe of band dunnage of the present utility model, comprise working steel tube 1, it is characterized in that dunnage 2 being arranged at the outer surface of working steel tube 1, joint along continuous straight runs and Vertical direction in working steel tube 1 and dunnage 2 have 4 to strengthen gusset 3, working steel tube 1 outer surface have along dunnage 2 both sides Steel Sleeve 4,4 ', working steel tube 1 and Steel Sleeve 4,4 ' toroidal cavity in have thermal insulation layer 5,5 ', Steel Sleeve 4,4 ' the upper end have humidity discharging pipe assembly 6,6 ', Steel Sleeve 4,4 ' port and the port of working steel tube 1 between have the welding section 7,7 of reservation '.
The thermal insulation pipe manufacture process of band dunnage of the present utility model is as follows: at first in the outer surface welding dunnage 2 of the intermediate section of working steel tube 1, this dunnage 2 is the square plate of middle band circular hole, substantially horizontal and Vertical direction along working steel tube 1 are strengthened gusset 3 four of dunnage 2 welding, be inserted in Steel Sleeve 4 in dunnage 2 both sides along working steel tube 1,4 ', and it is welded to dunnage 2 both sides is fixed, at Steel Sleeve 4,4 ' and working steel tube 1 between toroidal cavity in insert thermal insulation layer 5,5 ', at Steel Sleeve 4,4 ' upper end welding humidity discharging pipe assembly 6,6 ' with thermal insulation layer 5,5 ' communicate Steel Sleeve 4,4 ' port and the port of working steel tube 1 between the welding section 7 of reservation is arranged, 7 '.
Below in conjunction with description of drawings the utility model.
Fig. 1 is the longitudinal sectional view of the thermal insulation pipe of band dunnage of the present utility model;
Fig. 2 is the sectional view of A-A among Fig. 1.
Among the figure: 1-working steel tube; 2-dunnage; 3-reinforcement gusset; 4,4 '-Steel Sleeve; 5,5 '-thermal insulation layer; 6,6 '-humidity discharging pipe assembly; 7,7 '-reserve welding section.
Embodiment 1
The thermal insulation pipe that is used for the band dunnage of steam line.
Vapor (steam) temperature 250-270 ℃, working steel tube 1 external diameter is 377mm, wall thickness 8mm, length 2500mm, Steel Sleeve 4,4 ' external diameter be 625mm, wall thickness 7mm, length 1030mm, thermal insulation layer 5,51 selects for use soft rock beam thermal insulating material to make, and dunnage 2 is round-meshed square steel plate, and the length of side is 800mm, thickness 40mm, humidity discharging pipe assembly 6,6 ' external diameter of pipe 57mm, length 85mm, the top has rain cover.
Other is identical with embodiment 1 the microporous calcium silicate thermal insulating material except that thermal insulation layer 5,5 ' select for use.
The utility model compared with prior art has the following advantages:
1, the insulating tube with gripper shoe of the present utility model can be used for buried soak pipeline, Have good insulation, sealing property, reduce the heat radiation loss, can prevent that sealing infiltrates heat-insulation layer.
2, can prevent that the seepage pipeline section from expanding prolongs to other pipeline section.
But 3 prefabrications, on-the-spot easy construction, use are reliably.
Claims (3)
1, a kind of thermal insulation pipe with dunnage, comprise working steel tube (1), it is characterized in that dunnage (2) being arranged at the outer surface of working steel tube (1), joint along continuous straight runs and Vertical direction in working steel tube (1) and dunnage (2) have 4 to strengthen gusset (3), along dunnage (2) both sides Steel Sleeve (4) is arranged at working steel tube (1) outer surface, (4 '), at working steel tube (1) and Steel Sleeve (4), thermal insulation layer (5) is arranged in the toroidal cavity of (4 '), (5 '), in Steel Sleeve (4), there is humidity discharging pipe assembly (6) upper end of (4 '), (6 ') are in Steel Sleeve (4), reservation welding section (7) is arranged between the port of the port of (4 ') and working steel tube (1), (7 ').
2, a kind of thermal insulation pipe of band dunnage as claimed in claim 1 is characterized in that thermal insulation layer (5), (5 ') are soft rock wool heat-preservation material.
3, a kind of thermal insulation pipe of band dunnage as claimed in claim 1 is characterized in that thermal insulation layer (5), (5 ') are the microporous calcium silicate thermal insulating material.
