Abstract
The utility model discloses a compound steel pipes, it includes the steel pipe body, polyurethane insulation layer and lies in the glass fiber layer between the steel pipe body and the polyurethane insulation layer, still is equipped with nonrust steel pipe outside the polyurethane insulation layer, the inboard of the steel pipe body still is equipped with the anticorrosive coating that anticorrosive paint constitutes. This product crushing resistance, impact resistance, heat insulating ability, corrosion resisting property are excellent, and long service life is of a specified duration, is fit for being used for high -rise plumbing, fire control spraying system, and the warm circulating water decorum of leading to of central air conditioning, it is anticorrosive inside and outside the cable threading, the petrochemical system, the pipe is dredged in secret plumbing, and the colliery is various fields such as inflammable and explosive place in the pit.
Description
Technical field
The utility model relates to a kind of engineering tubing, specifically a kind of composite steel tube.
Background technique
In industry and civil engineering, the chemical fluid such as steam, liquid gas, acid, alkali, salt, living drainage, potable water etc. of various fluid, high pressure all need to be carried by pipeline.Although common metal steel pipe crushing resistance, the higher antiseptic property of bearing is poor, and working life is short, and cost of production is high.Composite steel tube it preserves the advantage of two kinds of different materials inherences due to it, and the complementary deficiency of they inherences, is thus widely used in the industrial fields such as oil field, chemical industry, electric power, brings obvious economy, environmental and social benefits.General composite steel tube is that metal material is made due to it, thus thermal conductivity is better, this makes its safety in utilization under some hot particular surroundingss be deteriorated, thermal energy consumption is many, such as, in the situations such as metallurgy, city heat supply water supply, large-sized boiler heat exchange duct, the people be easy to touching pipeline because of carelessness causes burn and scald, causes unnecessary actual bodily harm and economic loss to personnel.In recent years, increasing composite steel tube product emerges composite steel tube, but its compressive strength and bearing are not high, and Clad Steel body compound place easily ftractures, and causes shorten working life, insulation and corrosion resistance performance also uneven.
Model utility content
For problems of the prior art, the utility model provides a kind of new composite steel tube.This product crushing resistance, impact resistance, heat insulating ability, excellent anti-corrosion performance, long perfomance life, be suitable for high layer water supplying and discharging, spraying system of fire fighting, the central air-conditioner HVAC circulating water decorum, cable threading internal and external anti-corrosive, petrochemical system, underground water supply and drainage dredging pipe, the various fields such as underground coal mine combustible and explosive area.
The utility model is by the following technical solutions:
A kind of composite steel tube, it is characterized in that, it comprises steel tube body 3, polyurethane insulation coating 1 and the glass fibre layer between steel tube body 3 and polyurethane insulation coating 12, and polyurethane insulation coating 1 is outer is also provided with Stainless Steel Tube 5; The inner side of described steel tube body 3 is also provided with anticorrosive coat 4.
Described steel tube body 3 is carbon steel, and thickness is 6-10mm.
Described glass fibre layer 2 is entwined for fiberglass gridding cloth, and thickness is 4-6mm.
Described anticorrosive coat 4 is made up of titanium nano modification anticorrosive paint, and thickness is 2mm.
Described polyurethane insulation coating 1 thickness is 10-15mm.
Described Stainless Steel Tube 5 thickness is 10-12mm.
The beneficial effects of the utility model are: composite steel tube of the present utility model is provided with glass fibre layer and polyurethane insulation coating between steel tube body and Stainless Steel Tube, achieve the combination of double-level-metal steel pipe layer, the product not only long perfomance life not easy to crack manufactured, and there is excellent thermal and insulating performance, be suitable as very much changes in temperature conveyance conduit; It adopts titanium nano modification anticorrosive paint simultaneously, and antiseptic property is superior, and after multi-layer compound, crushing resistance and impact resistance also significantly improve.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure, 1 is polyurethane insulation coating, and 2 is glass fibre layer, and 3 is steel tube body, and 4 is anticorrosive coat, and 5 is Stainless Steel Tube.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
Embodiment
A kind of composite steel tube, it is provided with Stainless Steel Tube 5, polyurethane insulation coating 1, glass fibre layer 2, steel tube body 3 and anticorrosive coat 4 from outside to inside successively.
Wherein steel tube body 3 is carbon steel, and thickness is 6-10mm; Described glass fibre layer 2 is entwined for fiberglass gridding cloth, and thickness is 4-6mm; Anticorrosive coat 4 is made up of titanium nano modification anticorrosive paint, and thickness is 2mm; Described polyurethane insulation coating 1 thickness is 10-15mm; Described Stainless Steel Tube 5 thickness is 10-12mm.
Above-mentioned composite steel tube crushing resistance, impact resistance, heat-insulation and heat-preservation, excellent anti-corrosion performance, can be widely used in carrying the field such as the water supply systems such as life Chilled Drinking Water, hot water, direct drinking water and rock gas, oil, seabed liquid medium, mine aqueous vapor, partial chemical medium transport, long perfomance life in industry and civil building.
