Abstract
The utility model relates to a steel lagging direct burial anticorrosive insulating pipe for steel vapor with a steel plate bracket and a tide-discharging pipe. The utility model is an insulating straight pipe, an elbow, a T-piece and an insulating compensator which are formed by orderly laminating from external to inner of glass fibre reinforced plastics, an outer steel pipe, a rock surface pipe casing and a working steel pipe which are winded by fiber. The steel lagging direct burial anticorrosive insulating pipe for steel vapor has the advantages of weight bearing, no deformation, better thermal-insulating effect, less heat loss, good antiseptic effect and long service life, and the steel lagging direct burial anticorrosive insulating pipe for steel vapor is very suitable for the transportation of the superheated steam.
Description
Technical field
The utility model relates to direct-buried insulated pipe, particularly a kind of steel-sleeve steel steam direct buried anticorrosion insulating tube that is used to carry superheated vapor.
Background technique
The city heat supply pipeline adopts the direct-burried paving mode more at present, and the structure of existing heat supply pipeline is generally: innermost layer is a metallic conduit, and metallic conduit is provided with thermal insulation layer outward, and outermost surface is the plastic tube protective layer of PVC material.Thermal insulation layer wherein is a kind of to be the PVC foam material, and this material heatproof is low, can not be used for the conveying of superheated vapor; Another kind is the pearlite insulation watt of camber; when this insulation tile is fastened on the metallic conduit outside, many seams are arranged, between the adjacent tile fragment when superheated vapor passes through metallic conduit; because perlite properties of materials; micro-shrinkage phenomenon can take place in insulation tile, and the joint gap between them is strengthened, and the heat in the metallic conduit is distributed by seam; not only cause heat loss; but also can cause outer plastic protective layer expanded by thermal softening, in addition the cracking infiltration, the corroding metal pipeline.Promptly cause energy waste, shortened the working life of insulation pipe again greatly.
Summary of the invention
The purpose of this utility model is to be used to carry superheated vapor by a kind of steel-sleeve steel steam direct buried anticorrosion insulating tube with unique texture is provided, the purpose that reduce heat loss to reach, prolongs the insulation pipe life-span.The technological scheme that its technical problem that solves the utility model adopts is: a kind of steel-sleeve steel steam direct buried anticorrosion insulating tube that has stainless steel strut and humidity discharging pipe is provided, this thermal insulation pipe be by fiber fw frp, outer steel pipe, mineral wool cartridge and working steel tube from outside to inside successively lamination form; Stainless steel strut is welded on respectively on the outer steel pipe and working steel tube of thermal insulation pipe, and by fixation plate respectively with the welding of the outer steel pipe of thermal insulation pipe, working steel tube and stainless steel strut fixed support in addition.This thermal insulation pipe can be by fiber fw frp, outer steel pipe, mineral wool cartridge and the working steel tube straight tube that forms of lamination successively from outside to inside, also can be by fiber fw frp, outer steel pipe, mineral wool cartridge and the working steel tube pipe elbow, threeway and the insulation compensator that form of lamination successively from outside to inside.
Steel-sleeve steel steam direct buried anticorrosion insulating tube provided by the utility model is compared with existing thermal insulation pipe, has increased the bearing power of thermal insulation pipe, and not yielding, heat insulation effect is even; The outer field fiber fw frp steel structure of thermal insulation pipe effectively is not perishable, and advantage such as have that high insulating effect, heat loss are few, favorable anti-corrosion effect and life-span are long is specially adapted to the conveying of superheated vapor, has good market prospects.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
