To winding, realize that the auxiliary between pipeline is fixed, the quantity of the PE supports is no less than four groups, and the inner of adjacent PE supports
PUR foam is also filled with outside installation gap between portion, the outside of the PE supports is also closely arranged with HDPE modeling pipes, described
HDPE modelings pipe is also arranged with being filled with high density mineral wool molding sleeve, the outer end of the HDPE modelings pipe in the installation gap of PE supports
There is end to cover, the end set is with being also arranged with thermal shrinkable sleeve, the outer end integral type dress of the end set outside the junction of HDPE modeling pipes
Provided with adpting flange.
Preferably, the overall end shape of the PE supports is arch, and through frosted device polish it is coarse, without corner angle.
Preferably, the both ends of the PE supports contact connection with steel pipe and HDPE modeling pipes respectively.
Preferably, the outer end of the HDPE modelings pipe is covered by thermal shrinkable sleeve with end realizes that fixation is connected.
In the utility model, the new low temperature resistant pre- thermal insulating by calcium silicates be changed to it is light, durable, non-ignitable, be stale-proof,
The excellent thermal insulation insulation material high density mineral wool molding sleeve do not damaged by worms, due to the W/m.k of the material thermal conductivity≤034, significantly
Adiabatic heat insulating effect is improved, it is easy for installation；The HDPE of -70 DEG C of low temperature can be born by using instead（High density polyethylene (HDPE)）Modeling pipe, meets
Using effect of the ship-related products in pole cold air as under the conditions of, it more can guarantee that Preadiabetic tube still has longer use at low ambient temperatures
Life-span.
