Qingdao Dacang Anticorrosion Co., Ltd.  

Product Name: Lbe Internal Shot Removing and Rust Removal Line System Condition: New Certification: API Automation: Automatic Cleanliness: High Cleanliness Fuel: Electric Origin: China Product Description Reference Standard:SY/T 0457-2000 Steel pipe liquid epoxy internal anticorrosive coating standardsQ/SY JS 0034-2003 Recommendation of non-corrosive gas pipeline internal wall coveringAPI RP 5L2-2002 Recommended practice for non corrosive gas pipeline pipe internal coatingSY/T 6530-2002 Non corrosive gas transmission pipeline pipe internal coatingSY/T0442-2010 Technical standards of steel pipeline FBE powder internal anticorrosive coatingGB16297-1996 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 safetySteel pipe past inspection from the charging table to the internal coating operation platform.Pipe after preheating is in turn into rust removal waiting platform. pipe is in turn up moved to rust removing work position through pipe transition device, then cleaning and purging operations is carried out on internal wall .Derusting abrasive used is recycled by recycling system. The dust caused during rust cleaning is collected by dust processing system.Finished pipe is transported through in bounded and out bounded device to test platform and coating position. After testing qualified, sealing pipe end and no-coating area with adhesive tape paper , and then start the coating work. A set of blowing and coating device is equipped on the rotating platform to do purge and coating work on the internal wall of pipe.By coating trolley rod putting into the pipe, complete blowing and purging process, and run back at a constant speed to do spraying operations, uniformly coating work is done on the inner wall . After spaying the pipe continue to be rotated a certain period of time, to ensure that the coating is not flowing.After coating pipe is transited to curing position inspected internal coating surface .After inspecting using a fan to blow and purge internal volatile gases; Pipe after blowing is going into the curing chamber .Curing chamber using gas to start the heat exchange and cycle and realize the stability control of indoor temperature between 40 and 60 degrees, when the surface reach curing degree to be dry then go into the next process. Curing chamber keep a certain heat preservation measures. This process can be omitted when the environment temperature is above 40ºC, directly into the natural curing stacking area.Coated pipe is printed marking after curing qualified through the transition platform rolling into the finishing area.
