Qingdao Dacang Anticorrosion Co., Ltd.  

Product Name: Internal Fbe Coating Anticorrosion Production Line Condition: New Method Type: Automatic Certification: CE, ISO, RoHS Application: Internal Fbe Coating Line Product Description Internal FBE coating anticorrosion production lineTechnical Specification:The process of internal FBE coating: Hot melt or electrostatic costing. The power spraying system is consist of automatic electrostatic powder spraying device, Spraying gun hanging arm, hanging support, spraying gun and spraying gun cooling system(Water cooling or Vacuum insulation), power recycling system.FBE Coating material: FBE(Epoxy powder)Pipe Range:φ700-2500mmPipe length:8-12.5mmInternal wall cleaning tech:Shot blasting tech.Capacity:200m²/HMaximum rated power:2150kwReference StandardSY/T0442-2010 Steel pipe fusion bonded epoxy internal anticorrosive coating standardsGB16297-1996 Air pollution comprehensive discharge standardsGB12348-90 Standard of noise at boundary of industrial enterprisesJB/T 8355-96 General technical conditions of shot blasting equipmentSY/T 0407-97 Steel surface pretreatment before coating applicationGB/T8923-1998 Steel surface corrosion level and rust cleaning level before coatingGB/T15607-95 Coating work safety specifications, electrostatic powder spraying process safetyDescription of FBE Internal Coating ProcessFirstly, Derusting inner surface of steel pipe, under the condition of reaching derusting grade comply to standard, with Medium frequency heating, to achieve required temperature, then start spraying epoxy powder by spraying equipment. Coating thickness is controlled by adjusting coating volume and steel pipe rotation speed so as to meet the design requirements. Finally to do inspection and to mark qualified pipe transporting to the finished product area.InternalFBE Process Flow1)Hydraulic trolley transport pipe to internal shot blasting position and transport pipe to inspection platform after short blasting. 2)Internal blasting process of steel pipe after the shot blasting to make sure the internal wall if free of steel grit, steel shot and dust residue.3)To test the quality of steel pipe after shot blasting, qualified steel pipe is moved to powder coating position.4)Hydraulic trolley transport steel pipe to V shape roller and lay down on V shape roller way.5)Pipe is transmitted straightly by raised V shape roller to the end of roller way and then stop the transmission. 6)V shape roller get down and pipe is put down on spiral transmission rollers.7)Start the spiral transmission, when pipe enter MF induction coil, MF heat the steel pipe.8)When steel pipe go into spraying chamber, spray gun open automatically spraying on steel pipe, powder dust removal start automatically, run on removal mode. 9)MF equipment close when steel pipe end leave pipe end left medium frequency induction coil , when steel pipe end go into the spraying chamber and is detect spray gun will shut down automatically, spraying operations stop, dust removal device automatically run on the energy saving mode.10)When pipe is moved to the center of steel rack, rises V transmission roller within steel pipe length range and convey pipe to pipe download platform, hydraulic trolley transmit steel pipe to the next position, related operation is applicated such as coating inspection, etc.11)The inner coating is checked for spark leakage by final inspection and the inner coating with leakage point is repaired.
