Abstract
Disclosed is technology used for underground metal pipe anticorrosion treatment. The technology is characterized by specifically including: smashing an asphalt block, purifying the same in a physical mode, and placing the same in an open container prior to melting at high temperature, wherein the high-temperature container is provided with a real-time temperature monitoring device and a detector which is used for detecting a state of asphalt by using a stirring rod; spraying the asphalt in a molten state on a metal pipe wall subjected to dedusting and flaw detecting treatment; winding an asphalt carrier layer on the outer wall of the metal pipe, spraying the asphalt for 1-5 times repeatedly, detecting the thickness of the asphalt by online fixing the distance between the metal pipe and a sensor, and winding a protective film on the metal pipe after a predetermined value is achieved. The technology has the advantages that requirements of operators are lowered after equipment is operated, treatment technology is simplified, metal pipe anticorrosion treatment effect is improved, and application range is wide.
Description
Technical field
The present invention relates to metal tube preservative treatment mode, particularly a kind of for the antiseptic technique of underground metal tube.
Background technique
Under ground piping, often due to etching problem, causes breakage, causes seepage accident, causes damage, and for effectively anticorrosion, need to carry out preservative treatment to metallic conduit.
Summary of the invention
The object of the invention is in order to improve the antiseptic effect of metallic conduit, it is a kind of for the antiseptic technique of underground metal tube that spy provides.
The invention provides a kind ofly for the antiseptic technique of underground metal tube, it is characterized in that: described for the antiseptic technique of underground metal tube, be specially asphalt blocks material is pulverized, then physics mode is purified, and is placed in open containers high temperature melting; Elevated temperature vessel is with real time temperature monitoring device, simultaneously with adopting stirring rod to detect the detection device of pitch state; The pitch of molten state is sprayed on the metal pipe-wall after dedusting and flaw detection processing; Metal tube outer wall is wound around asphalt carrier layer, and spraying pitch, repeats 1～5 time, online by distance between fixing metal pipe and sensor, detects the thickness of pitch, meets after predetermined value, is wound around protective film.
Described real time temperature monitoring device is infrared temperature detection device, non-contact measurement.
The mode that described pitch condition checkout gear detects is, detects whether conformity of the resistance of stirring rod in whipping process: the pitch in molten state completely, stirs drag size evenly constant; While there is block material, can produce other large resistance state, and then judge that whether pitch is completely in molten state.
Described flaw detection processing mode is ultrasonic flaw detection mode.
Described for the antiseptic technique of underground metal tube, key issue is, the temperature of molten asphalt remains constant, and described real time temperature monitoring device convenient operation person adjusts heated condition in time, keeps temperature stabilization, is conducive to the abundant fusing of pitch.Adopt stirring rod to detect the detection device of pitch state, further guaranteed to monitor pitch in stable molten state, avoid the waste of heating source.
Advantage of the present invention:
Of the present invention for the antiseptic technique of underground metal tube, after equipment operation, reduced the requirement to operator, simplified treatment process, promoted metal tube preservative treatment effect, applied widely.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the present invention is further detailed explanation:
