What is steel embedding technology?

Steel sleeve steel embedded technology is a new technology, a new embedded steel bushing is a major breakthrough in the field of directly buried installation technology, this technology is suitable for use in high underground water level area.


1 it has the waterproof, leakproof, permeability, compressive strength and fully enclosed technical advantages.Steel sleeve steel directly buried insulating pipe has three layers of structure: medium steel pipe, anti-corrosion and supporting role of coat steel pipe, and the conveying pipe between steel tube filled with coat of superfine glass wool composition, including fillers can also be a graphite, silicate clay pipe shell or polyurethane foam.


2 sets of steel prefabricated directly buried insulating pipe steam is suitable for conveying 2.6 mpa, 360 jiashan bearings degrees centigrade steam or other high temperature medium, because of its outer sheath formed by steel tube, not only high strength, simple construction, maintenance, not easy to damage, and a longer service life.


3 keep the reliability of the groundwater seepage problem is the top issue facing the underground buried pipes, moreover, excellent mechanical strength is also directly buried pipeline problem that nots allow to ignore.Steel sleeve steel directly buried insulating pipe connection because the outer steel tube welding way, so it has very excellent sealing performance, and robustness of outer sheath pipe guarantee steel set of directly buried steel pipeline in the normal operation of the high underground water level area.


Purpose: 4 steam heat pipe is widely used in liquid and gas transmission pipeline, chemical pipeline heat preservation engineering, petroleum, chemical industry, the central heating network, the central air-conditioning and ventilation pipes, municipal engineering, etc.Steel steel insulation pipe insulation structure on the basis of sliding mode is divided into different: sliding inside and outside slides inside a sliding type 1, type: thermal insulation structure by working steel tube, aluminum silicate, drag reduction, microporous calcium silicate, heat insulation layer, stainless steel fastening tape, aluminum foil reflector, polyurethane thermal insulation layer, coat steel pipe, external anticorrosive coating.2, outside sliding type: thermal insulation structure by working steel tube, glass wool insulation layer, aluminum foil reflector, tighten belt, stainless steel sliding guide bracket, air thermal insulation layer, protecting steel tube, external anticorrosive coating.Coating: protection of steel pipe to avoid corrosion, corrosion of steel pipe, prolong the service life of steel pipe.2. The external protecting tube: protect insulation from the erosion of groundwater, pipe support work and can absorb a certain amount of external load, guarantee the normal work of the pipe work.3. Polyurethane foam layer: guarantee the medium temperature, ensure the protection pipe surface at room temperature.4. Block, reflector: ensure that organic foam into inorganic rigid not high temperature resistant layer;To reflect heat from high temperature resistant layer part.5. Inorganic rigid insulation: high temperature resistance, guarantee and the interface between the organic insulation layer temperature, keep the foam from coking.6. Drag reduction layer: the guarantee work steel pipe heat bilges cold shrink freedom of movement.7. Work steel pipe: ensure the normal flow of the medium.
