Description
Technical field
The present invention relates to machinery manufacturing technology field, be particularly related to a kind of stripping machine of oil gas long distance pipeline external anti-corrosion layer, being a kind of stripping machine of crawler-type large diameter pipeline external anticorrosive coating, is the necessary machinery of building oil gas long distance pipeline and emergency first-aid repair pipeline construction.
Background technique
The nineties is come, and for the oil gas long distance pipeline is anticorrosion, begins to adopt three-layer polyethylene (PE) technology for external corrosion-proofing.Be enclosed with anticorrosive coat at the long defeated pipe outer wall of oil gas, promptly on oil gas long distance pipeline outer wall, clinkery epoxy powder, PE adhesive and the anticorrosion medium of polyethylene are arranged respectively from the inside to surface, adopt hot application method to be solidificated in steel tube surface, thickness is 3～8 millimeters, thereby realizes the outer corrosion-resistant purpose of pipeline.This anticorrosion medium cementability is strong, the material hardness height, and antiseptic property is good.
In the accident maintenance and a station construction of natural gas pipeline, need remove anticorrosive coat in the welding part, expose body and just can cut or weld job.Because the long defeated pipe of oil gas outer wall wraps up anticorrosion medium bond strength is preferably arranged, to make cutting or weld remove (peeling off) anticorrosive coat one-tenth influence the subject matter of construction speed.In the construction operation, not only speed is slow to adopt the artificial manual method of peeling off usually at present, and it is also bad to peel off effect.
Summary of the invention
The objective of the invention is: a kind of crawler-type large diameter pipeline external anticorrosive coating peeling machine is provided, realizes removing the anticorrosive coat of the long defeated pipe outer wall parcel of (peeling off) oil gas.Adopt motor as peeling off power, drive the anticorrosive coat that the outer wall parcel is removed in the round brush rotation, and be that move along circumference on the anticorrosive coat surface of 219～1020mm pipeline, finish peeling off of pipeline anticorrosion coating, for cutting or weld job provide advantage at external diameter.
