Embodiment
In the following, the substantive distinguishing features and advantage of the utility model are further described with reference to example, but this practicality is new
Type is not limited to listed embodiment.
As shown in Figures 1 to 4, a kind of thermal insulation joint pipe fitting of the present embodiment, including main pipeline 1 and side ducts 2, side ducts
2 are arranged on 1 side of main pipeline, and the main pipeline 1 includes instrumentation tubes 11, heat-preservation cotton layer 12, outer protection tube 13 and erosion resistant coating 14, described
Heat-preservation cotton layer 12 is arranged on 11 outer surface of instrumentation tubes, and the outer protection tube 13 is arranged on heat-preservation cotton layer outer surface, the erosion resistant coating 14
It is arranged on outer protection tube outer surface.The side ducts 2 include humidity discharging pipe 21 and humidity discharging outer protection tube 22,22 row of being arranged on of humidity discharging outer protection tube
Damp 21 outer surface of pipe, the outer protection tube 13 are equipped with the mounting hole 131 for being used for installing connecting detection equipment, closing are equipped with mounting hole
Part 132.
In above-mentioned technical proposal, main pipeline can keep the temperature of instrumentation tubes by heat-preservation cotton layer, by setting erosion resistant coating
Main pipeline can be avoided to be corroded.It can be carried out by side ducts hydrophobic, two lateral canal roads are set in the present embodiment.Pass through setting
Mounting hole, can access the sensor detection line of detection device 10 when carrying out tubular service by the connection of screw thread mouth, inspection
Measurement equipment 10 for example detects the humidity or temperature of pipeline inner thermal insulating layer by the access of humidity measurement instrument or temperature-detecting device,
Judge whether pipeline inner thermal insulating layer has causes moist or impaired heat insulation effect to reduce because of leakage.When mounting hole when not in use, lead to
