Description
Technical field
The utility model relates to corrosion-proof technology for pipeline field, particularly relates to many impedances condensed type pipes for mining.
Background technique
Steel pipe not only for carrying fluid and powdery solid, exchange heat energy, manufacturing machine part and container, it or a kind of economic steel.Be coated with tagsort by plating, steel pipe is coated with feature by plated surface and can be divided into: clarinet (not plating painting) and plating coating pipe.Coating pipe has galvanized pipe, the steel pipe of pipe, chromium-plated tube, aluminizing pipe and other alloy-layers of aluminizing.Coated pipe has external coating pipe, undercoating pipe, inside and outside coating pipe.The coating of usual employing has the corrosion-inhibiting coating material of plastics, epoxy resin, coal tar epoxy and various glass mould.
At present, the gas used in most mine and liquid line are all steel pipelines, in use because residing geographical environment is more special, occur the problems such as resistance to SO_2 is poor, coating is easy to wear.Common anticorrosive coat is vulnerable to external force impact and occurs damage, causes pipeline corrosion protection ability and working life to decline.Though common anticorrosive coat can stop water molecule to corrode body, free Oxygen permeation cover coat can not be stoped and to react generation iron rust with steel substrate, finally causing coating and Matrix separation, lose anti-corrosion function.Have a kind of PE pipes for mining in addition, but cost is high, ring stiffness is poor; Also have a kind of PVC pipes for mining, but its shock resistance is poor, fragile, cause the accident.Steel pipe large-scale mine draw out methane and the pipe network use amount such as mine water-feeding & drainaging pipeline, fire sprinkler, down-hole whitewashing, positive/negative-pressure ventilation huge, the fine or not direct relation of steel tube performance the safety in production of mine.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of at relatively high temperatures by the many impedance condensed type pipes for mining of epoxy powder clinkering at body inner and outer surface, this inner tube wall bottom is corrosion-proof ring epoxy resins, outer wall is, resistance oxygen, sulfur resistive type epoxy resin and corrosion-proof ring epoxy resins antistatic through having of modification, has resistance oxygen, fire-retardant, sulfur resistive, wear-resistant, anlistatig excellent properties.
In order to solve the problem existing for above-mentioned technology, the utility model by the following technical solutions:
Many impedances condensed type pipes for mining, comprise steel pipe, described outer surface of steel tube is coated with corrosion-proof ring epoxy layer, described corrosion-proof ring epoxy layer outer surface is coated with modified epoxy layer, described steel pipe internal-surface is provided with corrosion-proof ring epoxy resins internal layer, solidifying after described corrosion-proof ring epoxy layer and modified epoxy layer spray successively, described corrosion-proof ring epoxy resins internal layer be sprayed on the internal surface of steel pipe after solidifying.
In the utility model preferred embodiment, the thickness of described modified epoxy layer is 200 μm-300 μm.
In the utility model preferred embodiment, the thickness of described corrosion-proof ring epoxy layer is 150 μm-200 μm.
In the utility model preferred embodiment, the thickness of described corrosion-proof ring epoxy resins internal layer is 200 μm-400 μm.
Many impedances condensed type pipes for mining of the present utility model not only has very strong antiseptic power and mechanical strength, there is the performance such as excellent fire-retardant, oxygen barrier, sulfur resistive, antistatic, wear-resistant, scratch resistance simultaneously, body longer service life, suitable especially mine operation environment.The utility model structure is simple, and cost is low, is easy to promote the use of.
