Examples
Fig. 1 is the utility model relates to a plastic cover seamless elbow embodiment's that protecting effect is good schematic diagram, as shown in the figure, the utility model provides a plastic cover seamless elbow that protecting effect is good, including protection outer tube 1, work inner tube 2 and heat preservation 3, 1 covers of protection outer tube are established in the outside of work inner tube 2, and protection outer tube 1 is the seamless outer tube of thermoforming integral type structure, and the outside surface does not have the slot that influences its performance, and bubble-free, crackle, sunken, impurity, colour inequality defect, and the material of protection outer tube 1 is high density polyethylene resin, and it is big to make protection outer tube 1 have tensile yield strength, and elongation at break is high, and the vertical shrinkage rate of arbitrary pipeline section is little, the long characteristics of resistant environmental stress fracture time.
The outer wall of the protective outer pipe 1 is coated with the anticorrosive paint 5, so that the anticorrosive performance of the seamless elbow is improved. The inner wall of the protective outer pipe 1 and the outer wall of the working inner pipe 2 form a cavity, the heat preservation layer 3 is filled in the cavity, the heat preservation layer 3 is made of hard polyurethane foam, foam holes of the hard polyurethane foam are uniform and fine, the heat preservation and insulation capacity is good, heat loss is reduced, and the heat preservation effect when the seamless elbow conveys a medium is enhanced.
Protection outer tube 1, work inner tube 2, heat preservation 3 are the arc structure that the radian equals, and the design of arc structure can ensure that heat preservation 3 hugs closely with protection outer tube 1 and work inner tube 2. Be equipped with insulating layer 4 between heat preservation 3 and the work inner tube 2, insulating layer 4 is aerogel composite resin, and aerogel composite resin thermal conductivity coefficient is low, and the heat of the high temperature medium of conveying in the pipeline can be blocked by its by a wide margin, and only few heat transfer is to heat preservation 3 departments to avoid polyurethane to receive pyrolysis, carbonization deformation, lose the heat preservation effect, prolong the life of seamless elbow.
