Abstract
The utility model relates to a mental pipe, in particular to a metal pipe, which can prevent pipes from eroding, rusting during a long period of use and is hard to reproduce bacteria. An anti-erosion, high and low temperature resistant medium pipe includes steel pipe, the internal and external walls of the steel pipe are independently coated with a hot setting epoxy resin layer. The utility model can prevent water from a second pollution; the mechanical strength is high and the utility model can bear a high temperature up to 120 degrees and a low temperature to minus 40 degrees; the coating will not change. Moreover, the utility model is anti-erosion and the service life is long.
Description
(1) technical field:
The utility model relates to a kind of metal pipe, particularly a kind ofly prevents that the tubing burn into gets rusty, is difficult for vegetative metal pipe when long-term the use.
(2) background technique:
At present, no matter be to use pipeline during enterprise produces, still resident's heating, supply water, the ground buried pipeline, in the fire line, the pipeline major part of the input media that uses is to use zinc-plated tubing, because galvanized pipe can not get changing and safeguarding for a long time, make that a large amount of breedings of bacterium can aggravate corrosive pipeline in the pipe network, produce iron rust and pipe scale, consume oxygen in water, improve the bad smell of water colour and water, increase turbidity and bacterial plate counts, produce biological clay, be the appearance of macro-organism body and pathogen, breeding creates conditions, and forms biolabile water, cause the secondary pollution of water quality, directly threaten water treatment plant's operation and people's health safety.Even cause pipeline obstruction, booster, disconnected pipe serious problems, cause unnecessary economic loss to people's life.
(3) summary of the invention:
The technical problems to be solved in the utility model provides a kind of mechanical strength height, makes water quality can not be subjected to corrosion-resistant, the high-low temperature resistant medium transport pipe of secondary pollution.
Corrosion-resistant, high-low temperature resistant medium transport pipe comprise steel pipe, and its main points are to be coated with the thermosetting epoxy resin layer on the inner and outer wall of steel pipe respectively.
Above-mentioned thermosetting epoxy resin is EPY
2The type thermosetting epoxy resin comprises I, II, III, IV type EPY
2Thermosetting epoxy resin.
Above-mentioned steel pipe is a common steel tube, also can be seamless steel pipe.
The utlity model has and prevent advantages such as water pollution once again, mechanical strength height, high temperature resistant+120 ℃, low temperature resistant-40 ℃, coating no change, corrosion-resistant, long service life.
The utility model be applicable to for tap water, heating, the pipeline that uses such as buried pipeline, fire-fighting.
(4) description of drawings:
Fig. 1 is a kind of example structure schematic representation of the utility model.
(5) embodiment:
Corrosion-resistant, high-low temperature resistant medium transport pipe comprise seamless steel pipe 1, and its main points are to be coated with EPY on the inwall of seamless steel pipe 1
2Thermosetting epoxy resin layer 2 is coated with EPY on the outer wall of seamless steel pipe 1
2Thermosetting epoxy resin layer 3.
Claims (2)
1, corrosion-resistant, high-low temperature resistant medium transport pipe comprises steel pipe (1), it is characterized in that being coated with respectively on the inner and outer wall of steel pipe (1) thermosetting epoxy resin layer (2), (3).
2, corrosion-resistant, high-low temperature resistant medium transport pipe according to claim 1 is characterized in that described thermosetting epoxy resin layer (2), (3) are respectively EPY
2The type thermosetting epoxy resin.
