产品介绍 ( Product Presentation )

Threaded locking ring high pressure heat exchanger is a kind of high temperature,high pressure heat exchanger,now has been widely applied to a million tons grade hydrocracking device of maoming’s petrochemical industry,jinling’s petrochemical industry and qilu’s petrochemical industry at home.Threaded locking ring high pressure heat exchanger adopts threaded pressure-bearing ring to support high pressure,use various grades of mealing gaskets(washer) to seal inside,esures it safety and reliable.When the heat exchanger is operated,the bolt is tightened to get rid of leakage between medium and outside,its sealing is reliable. Because the structure of heat connected with heat exchanger directly,when the maintenance is needed,Only the internal parts is disassembled and assemlbed mechanically,The high pipelines is not needed disassembled.The heat exchanger’s Structure is more complex,its disign calculation is more tedious,Ita machining parts is more much,and its tolerance and cooperation requirement is more strict,its screw thread of high accuracy ruquirement of big diameter is needed to process by means of numerical control machine tool.

Reaction effluent-hot mix hydrogen raw oil heat exchanger: U tube type threaded locking ring high pressure heat exchanger of DIU600-17.3/18.6-154-4/19-2I model is a part of Ⅲ category of vessel.
