Abstract
The invention discloses a joint-coating and welding-free pipe connecting device and an application method, belongs to a pipe welding joint technology, and aims to overcome the defects of other technologies. The structural relationship is that one end of a first pipe is connected with a thin conical plug by using a first flange, and one end of a second pipe is connected with a flared plug by using a second flange; a thin conical end of the thin conical plug sleeves in a wide opening of the flared plug; the thin conical plug and the flared plug have a conical degree of 10-15 degrees; a carbon fiber sealant is arranged between the thin conical plug and the flared plug; the second flange can rotate randomly before being bolted.
Description
Technical field: the present invention relates to pipeline welded joint technology, especially a kind of without the unjointed assembling pipe joint of repaired mouth and application process.
Background technique: originally, people are when Pipe installing connects, tube and tube is mostly taked to dock welding or Flange joint, its existing problems are, pipeline welding Placement, must carry out rust cleaning and namely preservative treatment is commonly called as repaired mouth in on-the-spot butt welded seam place, according to current each oil field oil pipeline corrosion condition, all perforation are all that repaired mouth place causes.Flange joint jointing resistance to pressure is bad, and the time has been grown and caused perforation.
Summary of the invention: the object of this invention is to provide well-set a kind of without the unjointed assembling pipe joint of repaired mouth and application process, which overcome the shortcoming of other technology, the object of the present invention is achieved like this, it is in one end of first pipeline with the thin tapered plug of the first Flange joint one, in one end of second pipeline with the second Flange joint broadening formation plug; The thin cone end of thin tapered plug is inserted in the wide-mouth of broadening formation plug; The tapering of thin tapered plug and broadening formation plug is all 10-15 degree; Carbon fiber sealer is had in the middle of thin tapered plug and broadening formation plug; Second flange can arbitrarily rotate before upper bolt.
Carbon fiber sealer is made up according to certain technique of resin 60 kg, curing agent 25-30 kg, carbon dust 20-35 kg, zirconium oxide 15-26 kg.
Carbon fiber sealer is high temperature resistant 200 degrees Celsius, by force corrosion-resistant, soak at acid-alkali salt and never degenerate for 90 days, anti-oxidant good endurance.
Application process of the present invention, sealing gasket is encased inside broadening formation plug bottom by the first step; Thin tapered plug and broadening formation plug are coated carbon fiber sealer by second step; The thin cone end of thin tapered plug is inserted in the wide-mouth of broadening formation plug by the 3rd step; 4th step screws in screw internal fixtion by bolt.
Meaning of the present invention is: structure of the present invention is simple, easy to operate; Be connected firmly.
