It is required that very high, welding is technical bottleneck.The manufacturer of domestic this technology of grasp is seldom at present.Thus purchase cost is very high, shadow
The popularization and extensive use in market are rung.
The tube sheet of single tube plate no-welding type heat exchanger is clamped by flange, passes through the applying power clamping pad such as bolt, packing ring, nut
Piece is to reach the sealing of main pad；Pad and O-ring are cased with to form the seal assembly between exchanger tubes and tubesheets on the outside of heat exchanger tube,
And thrust compression seal component is applied by screw plug (center is with holes, does not influence flow of media) and reaches sealing.Its tube sheet
Usually nonmetallic or metal surface covers nonmetallic anticorrosive coat, and pore screw thread is prevented in nonmetallic surface or relatively thin metal
Processed on rotten layer.This screw thread can not bear larger pressure or/and higher temperature.Acted in larger pressure and/or higher temperature
Under, sealing cannot be effectively ensured, easily failure.When being leaked at heat exchanger tube, it is impossible to find in time, also cannot be timely
Processing, causes potential risk and even results in accident.So as to limit the application of such product in the industry.
No-welding type double tube plate heat exchanger, common double tube plate heat exchanger, inside and outside two pieces of tube sheets are provided with, can be prevented
Pipe, shell side kind storeroom contact with each other.An observation chamber is formed between two tube sheets, is easy to find leakage in time.When pressure or temperature
When higher, tube sheet easily deforms.Bolt applying power among tube sheet is played to the deformation for reducing tube sheet certain
Effect, but this power can not be uniformly applied on every heat exchanger tube, thus the pressure that seal assembly obtains at each heat exchanger tube
Clamp force differs in size together.The thrust that heat exchanger tube seal assembly at bolt and bolt obtains is big, is preferentially sealed.And
The pad that now there may be part heat exchanger tube cannot get enough thrusts, it is impossible to realize sealing.If now continue to increase spiral shell
Post and bolt may cause the pad overvoltage of good seal and damage to pad thrust.On the other hand, each tubesheet holes and each
Seal assists the scantling of sealing to have differences so that indivedual points can not be handled with the method for overall applying power and are let out
The problem of leakage.Seal assembly on heat exchanger tube, even individual defects, wants replacing and also has to take outer tube plate once damaging
It is lower to change.Even if damaging a pad, seal assembly on all heat exchanger tube and heat exchanger tube is also reinstalled.Therefore tie up
Repair and grown with the off-time, larger production suspension induced losses can be brought to equipment user.Therefore, this structure does not consider the equipment later stage
Maintenance, operating cost, the defects of certain in itself be present in structure design.And though the double tubesheet that the technology provides has monitoring leakage
Function, but without follow-up counter-measure.After leaking can only shut-down (breakdown) mainteance, cause production stop work, cause economic loss.
