The both sides of described polyureas coat are fixed on support ring, and the outer seam of adjacent two pieces of polyureas is coated with Stainless Steel Cloth, and is bonded by two pieces of polyureas coats by polyureas.
The head and the tail snap-fit engagement of described polyureas coat, on the same line, this straight line is coated with Stainless Steel Cloth, and Stainless Steel Wire is coated with polyureas on the net in the clamping position of all polyureas coats.
Described support ring is made up of three-decker, is wherein glass fibre, and centre is foam, and another side is polyurea layer, is fixed between described support ring and pipeline body by foam.
High-density foam is installed at described pipeline body conduit saddle position, and at piece of surface covering glass steel.
The end face of described polyurea layer is smooth surface, and the bottom of polyurea layer is roughened surface.
Compared with prior art, the beneficial effects of the utility model are:
This high tenacity fire-retardant heat insulation pipeline is at the coated one deck polyureas coat of pipe surface, and polyureas coat is that polyurea coating Stainless Steel Cloth forms, compared with original glass fibre reinforced plastics, it has the following advantages:
1, the pliability of polyureas coat is good, collapsible, can prevent that hull from rocking, pipeline shrinks and damaged.
2, the intensity of polyureas coat is high, and want high 10 times compared with original glass fibre reinforced plastics intensity, it is not easy breakage.
3, the good flame resistance of polyureas coat, when after polyureas surface carbonation, because Stainless Steel Cloth is combined with polyureas, surface can not be peeled off, and can prevent inner PU foam from burning further, reach better flame retardant effect.
4, pipeline outer wall is coated with foam, and pipeline can, gapless integrated with foam, and make the good airproof performance of pipeline, heat insulation effect is good.
5, polyureas coat and elbow, not-go-end can be prefabricated, cost-saving, convenient installs, and improves the installation efficiency of pipe insulating layer.
