Body is made up of inner and outer tubes, and heat-insulation layer is provided between said inner tube and the outer tube.
Further, the surface of the outer tube, first flange disk and second flange disk scribbles makrolon material.
Further, the inwall of said inner tube scribbles KN17 polymer ceramic polymer coatings.
Further, the bolt is stud.
Further, the reinforcement is evenly distributed on first flange disk and second flange disk.
Compared with prior art, the beneficial effects of the utility model are：The hollow rod, by hollow rod head peace
Mounted in the inside of internal thread box cupling, first flange disk and second flange disk are connected, be bolted connection, bolt is double end
Bolt is easy to improve the intensity between box cupling, and reinforcement is evenly distributed on first flange disk and second flange disk, strengthens hollow
The intensity and rigidity of rod collar, to save material usage, mitigate weight, reduces cost, and hollow rod body is by inner tube
Constituted with outer tube, the inwall of inner tube scribbles KN17 polymer ceramic polymer coatings, can be in case sulfuric acid corrosion, hcl corrosion and alkali
Property material corrosion, be easy to improve service life of equipment.
