Abstract
The invention discloses an installation method of an end socket sealing gasket of a heat exchanger. The installation method is characterized in that the periphery of the end socket sealing gasket formed by pressing stainless steel wires is provided with a high circular ring made by a thin stainless steel plate in a spot welding or adhering way, the end socket sealing gasket is buckled on a bulged flange sealing surface during installation, the weight of a flange sealing gasket can be supported, and an end socket cannot offset and slide down when the end socket of the heat exchanger is installed; or symmetrical sealing gasket fixing points are arranged on an end socket flange disk sealing surface on the heat exchanger by using an adhesive tape, and 2-4 sealing gasket fixing points are arranged on a sealing surface of a baffle plate; a layer of Loctite 510 or 515 adhesive can be coated between the sealing gasket fixing points on the flange sealing surface and the sealing gasket fixing points on the sealing surface of the baffle plate, the sealing gasket is adhered to the flange sealing surface, and the end socket cannot offset and slide down when the end socket of the heat exchanger is installed. According to the installation method disclosed by the invention, the installation quality of installing the end socket sealing gasket of the heat exchanger and the working efficiency of installing and replacing the end socket sealing gasket of the heat exchanger are increased, the service life of the sealing gasket is prolonged, and the maintenance cost is reduced by about one hundred thousand yuan every year.
Description
Technical field
An installation method for exchanger head sealing gasket, can be applicable to installation and the replacing of the usual means exchanger head sealing gasket of petroleum chemical industry, guarantees that sealing gasket and heat exchanger are concentric.
Background technology
When the installation of exchanger head sealing gasket and replacing construction operation, the movement of end socket and the reason of sealing gasket tenesmus when being subject to the size, weight of sealing gasket and end socket is installed, gasket seal is difficult to accomplish to keep its roundness and flatness, to such an extent as in installation process, easily fall into impurity, affect sealing effectiveness; Due to the tenesmus of gasket seal, easily cause the effective area of gasket seal sealing to reduce, and easily cause departing from of subgasket edges simultaneously, increased the possible factor of sealing face leakage.Exchanger head metal is wound around sealing gasket because heat exchanger specification is a lot, cannot purchase in batches, can only be single only customized, therefore price is higher, such as the pad that diameter is 2000mm, price can reach 3000 yuan, and the pad price that annual overhaul of the equipments is changed reaches 150,000 yuan.According to conventional construction method, end socket installation disqualification rate is generally between 40%～50%, and its Intermediate gasket damages accounting and reaches 60% of disqualification rate.The direct economic loss causing reaches 50,000 yuan.In addition, because pad damages, need to be again customized, delay the duration, can cause again larger economic loss.
Summary of the invention
The object of this invention is to provide a kind of installation method of exchanger head sealing gasket, overcome the defect that above-mentioned prior art exists.
Technical scheme of the present invention is achieved in the following ways:
Suppressing the periphery spot welding of the end socket sealing gasket forming or the high annulus that the thin corrosion resistant plate of use of bonding is made with stainless steel wire, when installation, be buckled on protruding flange sealing surface, prop up the weight of flange gasket, when mounting heat exchanger end socket, can not be offset and glide or cover flange dish sealing surface on heat exchanger on stick with glue band and make symmetrical sealing gasket fixing point, on the sealing surface of dividing plate, make 2-4 sealing gasket fixing point; On the sealing surface between the sealing gasket fixing point of flange sealing surface and between dividing plate sealing gasket fixing point, be coated with happy safe 510 or 515 adhesive of one deck, sealing gasket is bonded on flange sealing surface, when mounting heat exchanger end socket, can not be offset and glide.
The height of annulus is 3-5mm, and thickness is 0.5mm, and internal diameter is greater than the external diameter of heat exchanger flange sealing surface.
Between fixing point, angle is 30
0or 40
0or 60
0,
Advantage of the present invention is: solved the problem of the skew of mounting heat exchanger end socket gasket seal and tenesmus, reached simple, convenient flexible, time saving and energy saving object.Improve the installation quality of mounting heat exchanger end socket sealing gasket and the operating efficiency efficiency of changing exchanger head sealing gasket has been installed.Extend the service life of sealing gasket.Annual more than 10 ten thousand yuan of the maintenance costs of saving.Improved heat exchanger operation time rate, exempt from the economic loss that causes of stopping production and take units up to a million.

Detailed description of the invention
Technical scheme of the present invention is achieved in the following ways:
Suppressing the annulus that the periphery spot welding of the end socket sealing gasket forming or the height of the thin corrosion resistant plate making of use of bonding are 3-5mm with stainless steel wire, when installation, be buckled on protruding flange sealing surface, prop up the weight of flange gasket, when mounting heat exchanger end socket, can not be offset and glide or cover flange dish sealing surface on heat exchanger on stick with glue band and make symmetrical sealing gasket fixing point, between fixing point, angle is 30
0or 40
0or 60
0, on the sealing surface of dividing plate, make 2-4 sealing gasket fixing point; On the sealing surface between the sealing gasket fixing point of flange sealing surface and between dividing plate sealing gasket fixing point, be coated with happy safe 510 or 515 adhesive of one deck, sealing gasket is bonded on flange sealing surface, when mounting heat exchanger end socket, can not be offset and glide.The problem that has solved the skew of mounting heat exchanger end socket gasket seal and tenesmus, has reached simple, convenient flexible, time saving and energy saving object.Improve the installation quality of mounting heat exchanger end socket sealing gasket and the operating efficiency efficiency of changing exchanger head sealing gasket has been installed.Extend the service life of sealing gasket.Annual more than 10 ten thousand yuan of the maintenance costs of saving.Improved heat exchanger operation time rate, exempt from the economic loss that causes of stopping production and take units up to a million.
