It is further that described passivation barrier coat also includes using epoxy resin as major ingredient in the epoxy resin
It is passivated condiment and iron oxide red mica.
A kind of anticorrosive construction technique for the shell and tube cooler, described anticorrosive construction technique passes through to from cooling
Cooling water pipe inwall, the division board dismantled on device body carries out artificial smearing and perfusion corrosion-inhibiting coating, then again will be described
Cooling water pipe, division board as former state reinstall and carry out it is pressure-resistant leak detection complete the shell and tube cooler anti-corrosion protection work.
It is further to be carried out in the steps below when carrying out coating perfusion, that is, after the completion for the treatment of that coating is irrigated, repeatedly
The described cooling water pipe of handstand, rotation, upset and division board complete the uniform smearing of coating.
The beneficial effects of the invention are as follows：The application in the shell and tube cooler newly bought back by realizing the cold of refrigerating function
But one layer of corrosion protective covering is coated with pipe inner wall, it is then refilled and reinstalls original position and use.So, due to there is the anti-corrosion to protect
Sheath is protected to the inwall of cooling water pipe, a large amount of incrustation scales occurs so as to effectively avoid or extend cooling water pipe inwall
Time, and avoid or extend the corrosion that cooling water pipe accelerates the cooling water pipe because of build-up of limescale, reach and effectively reduce
Line clogging rate, the purpose of extension device entirety usage cycles.
Brief description of the drawings

Fig. 2 be the present invention relates on cooling water pipe coat corrosion protective covering be Fig. 1 I portions enlarged drawing.
Marked in figure：Cooling water pipe 1, shell and tube cooler body 2, corrosion protective covering 3, passivation barrier coat 4, isolation
Plate 5.
Embodiment
It is that one kind that the present invention is provided can effectively reduce line clogging rate as shown in Figure 1 and Figure 2, extension device integrally makes
With the shell and tube cooler for metallurgy rolling system in cycle, and the anticorrosive construction work for the shell and tube cooler
Skill.Described shell and tube cooler, including the shell and tube cooler body 2 of cooling water pipe 1 is disposed with, constituting the shell and tube
One layer of corrosion protective covering 3 is coated with described in each part of cooler body 2 on the madial wall of cooling water pipe 1.Described anticorrosive construction
Technique carries out artificial smear by the cooling water pipe inwall to being dismantled from cooler body, division board and applied with perfusion anti-corrosion
Layer, then described cooling water pipe, division board are reinstalled and carry out preventing for the pressure-resistant leak detection completion shell and tube cooler as former state again
Corruption protection work.The application on the inwall of cooling water pipe 1 for realizing refrigerating function for the shell and tube cooler newly bought back by applying
One layer of corrosion protective covering 3 is covered with, it is then refilled and reinstalls original position and use.So, due to having the corrosion protective covering 3 to cooling water
The inwall of pipe 1 is protected, so as to effectively avoid or extend the time that a large amount of incrustation scales occurs in the inwall of cooling water pipe 1, with
And the corrosion that cooling water pipe 1 accelerates the cooling water pipe 1 because of build-up of limescale is avoided or extends, reach and effectively reduce line clogging
Rate, the purpose of extension device entirety usage cycles.
In above-mentioned embodiment, with reference to the function of shell and tube cooler described herein, and using the property of medium,
Medium described herein includes the cooling medium based on water and needs the medium of cooling, anti-corrosion protection described herein
