Description
technical field:
the utility model relates to the buried composite thermal pipeline of a kind of diameter reducing type corrosion-resistant high-temperature.
background technique:
at present, it is domestic that what generally adopt for triode net cold and heat supply is all steel insulating pipe bend preparation process, continuous intercept is needed to weld and add a large amount of construction costs when installing in cell unit corridor, a large amount of economic losses is created from construction cost, thermal losses has occurred a large amount of unnecessary losses, pipeline conveying aspect also exists the problems such as operation troubles of getting rusty, original technology and technique in a word, in environmental protection, energy-conservation, economical, safety, the aspects such as stability will not reach the performance standard of prefabricated direct-buried thermal insulation pipe crosslinked polyethylene working pipe process engineering far away.
model utility content:
the purpose of this utility model is to provide the buried composite thermal pipeline of a kind of diameter reducing type corrosion-resistant high-temperature.
above-mentioned object is realized by following technological scheme:
the buried composite thermal pipeline of a kind of diameter reducing type corrosion-resistant high-temperature, its composition comprises: working steel tube, the external diameter surface of described working steel tube is connected with high-temperature resistant fiber felt, the external diameter surface of described high temperature fiber felt is connected with composite calcium silicate insulation tile, the external diameter surface of described composite calcium silicate insulation tile is connected with polyurethane foamed thermal-insulating layer, described polyurethane foamed thermal-insulating layer is connected with outer steel pipe, the external diameter surface of described outer steel pipe scribbles one deck and strengthens corrosion-inhibiting coating.
the described buried composite thermal pipeline of diameter reducing type corrosion-resistant high-temperature, described high-temperature resistant fiber felt is protection bed course, and described composite calcium silicate insulation tile is organic heat-insulating layer.
the described buried composite thermal pipeline of diameter reducing type corrosion-resistant high-temperature, when described working steel tube diameter is less than or equal to 150mm, selects seamless steel pipe, when diameter is greater than 150mm, selects spiral weld steel pipe.
the described buried composite thermal pipeline of diameter reducing type corrosion-resistant high-temperature, described corrosion-inhibiting coating is polyethylene anticorrosive coating or the glass yarn winding epoxy resin layer of two layers or three layers or adds intensity level epoxy coal tar pitch coating.
the described buried composite thermal pipeline of diameter reducing type corrosion-resistant high-temperature, the inside diameter surface of described outer steel pipe welds with triangle fixing support rack side, and the opposite side of described triangle fixing support rack welds with the external diameter surface of described working steel tube.
the described buried composite thermal pipeline of diameter reducing type corrosion-resistant high-temperature, the outer layer surface of described reinforcement corrosion-inhibiting coating has bearing, and permanent moisture discharging opening established by the pipeline of described polyurethane foamed thermal-insulating layer.
the beneficial effects of the utility model:
1. the utility model adds steel pipe corrosion-proof, polyurethane foam insulation layer and interior working steel tube by external protective steel tube to combine.Steel sleeve steel steam compound thermal insulating pipe is applicable to carry 2.5MPa, the steam of less than 350 degrees Celsius or other medium, and this product steel pipe does external protection coating, has intensity high, and not fragile, Construction and Maintenance are easy, the advantage of long service life.
the utility model can reduce on-site construction time, accomplishes convenient and quick construction, and can guarantee the quality of anticorrosion, waterproof, the aspect such as insulation and mechanical strength of all pipe fittings.The outer pillar of all pipe fittings all adopts anticorrosion, the heat preserving mode identical with straight length, after needing to fill certain thickness soft material around pillar outside during site operation, then back-up sand compacting, concentrate to eliminate elbow stress.For elbow bend, in running, flexible in the pillar confined space outside for compensating axis that elbow occurs and Side movement and working steel tube, according to the heat displacement amount calculated, local increases the caliber of outer pillar, and for the elbow being less than 90 DEG C, outer pillar does not need overstriking.
hot insulated line of the present utility model establishes permanent moisture discharging opening, makes the smooth and easy discharge of steam produced in thermal insulation layer, do not cause thermal insulation layer and the breakage of outer pillar.In (outward) fixed bearing arranges humidity discharging pipe, one end of humidity discharging pipe is deeply in fixed bearing thermal insulation layer, and the other end by humidity discharging pipe extraction ground, and does rainproof, waterproof and preservative treatment at end.
the utility model long-term safety operational reliability maximum (having good intensity, rigidity, heat resistance, advanced technology); Water-tight best performance, pipeline corrosion protection is to ensure the life-span long (Corrosion Protection of Fiber Reinforced Plastics or epoxy coal asphalt paint anticorrosion); Potential risk little (fatigue strength of outer steel pipe is large, the environment that long-time running is being expanded with heat and contract with cold, and interface is easy to throw off unlike external glass fibre reinforced plastics pipe); Obvious energy conservation (heat insulation effect is better for good seal performance, ne-leakage); Easy construction, node seals;
5. the utility model has good leakage performance, rigidity and hydraulic performance, has very high mechanical strength and excellent decay resistance. and it can protect tubing in transportation, installation and use process not by the destruction that extraneous factor causes.
