Abstract
The invention discloses spherical tanks to be heat-treated insulation blanket installation method, comprising: firstly, being heat-treated requirements of one's work, the strip of prefabricated fixed insulation blanket according to spherical tank；Secondly, after strip is made, strip is combined in the upper lower manhole outer wall of spherical tank, equatorial zone and other broadwise endless belts, form the fixed strip of cricoid broadwise, simultaneously, cricoid radially fixed strip is also installed radially, the fixed strip of broadwise and radially fixed strip constitute fenestral fabric；Finally, insulation blanket is mounted on the bolt on the strip of fenestral fabric, by compress gasket, with bolt presses, so as to which insulation blanket is fixedly mounted on outside spherical tank.Using method of the invention, either insulation blanket or strip, it can produce once and be used for multiple times, save material.And due to being prefabricated steel, production and application is all very convenient, and speed of application is fast.After the present processes install insulation blanket, insulation blanket can be effectively fitted in outside spherical tank, and heat insulation effect is good.
Description
Technical field
The present invention relates to a kind of installation methods of insulation blanket, and in particular to a kind of spherical tank heat treatment insulation blanket installation method,
Belong to equipment installation Technology field.
Background technique
According to design requirement and according to GB12337-1998 " Steel made Ball storage Tank " related technical standard, in order to eliminate spherical tank
The residual stress of assembling and welding stablizes the geometric dimension of spherical tank, improves the tissue and performance of welding point and heat affected area, reaches
To hardness is reduced, the purpose of plasticity and toughness is improved, further discharges the pernicious gas in weld seam, the hydrogen embrittlement of weld seam is prevented and splits
The generation of line.Spherical tank construction need to carry out POST WELD HEAT TREATMENT OF ENTIRE.
General spherical tank heat treatment insulation blanket installation is all to take iron wire to tie in spherical tank outer wall without forming fixed method
The method of bundle, this method speed of application is slow, and difficulty is big, and heat insulation effect is poor, and waste of material is big and is disposable.To understand
Certainly this problem, the present invention provide spherical tank and are heat-treated insulation blanket installation method, propose to spherical tank heat treatment insulation blanket installation prefabricated
Combination is installed and used, and speed of application is fast, and heat insulation effect is good, and material is reused.
Summary of the invention
The technical problems to be solved by the invention are in view of the deficiencies of the prior art, to provide a set of spherical tank heat treatment heat preservation
Blanket installation method solves the disadvantage that iron wire binding method is taken in spherical tank heat treatment insulation blanket installation, provides spherical tank heat treatment heat preservation
Blanket New Installation Method proposes that Prefabricated composite is installed and used to spherical tank heat treatment insulation blanket installation, and this method speed of application is fast, heat preservation
Effect is good, and material is reused.
The technical solution adopted by the present invention to solve the technical problems is:
Spherical tank is heat-treated insulation blanket installation method, comprising:
Firstly, requirements of one's work are heat-treated according to spherical tank, and in conjunction with the size of spherical tank, the strip of prefabricated fixed insulation blanket, in advance
The strip of system includes top manhole annular fixing belt steel and lower part manhole annular fixing belt steel, broadwise using position according to strip
Annular fixed strip, radial ringed fixed strip；
The both ends of the strip are provided with the hole for installing fixing bolt, can according to need and carry out independent assortment increase strip
Length, meet the needs of different size spherical tank；
On strip, the equidistant bolt being welded with for fixing insulation blanket, and it is configured with nut and compress gasket.
Secondly, after strip is made, by strip in the upper lower manhole outer wall of spherical tank, equatorial zone and other broadwises annular
Band is combined, and forms the fixed strip of cricoid broadwise, meanwhile, radially fixed strip, broadwise fixing belt are also installed radially
Steel and radially fixed strip constitute fenestral fabric.
Finally, insulation blanket is mounted on the bolt on the strip of fenestral fabric, by compress gasket, with bolt pressure
Tightly, so as to insulation blanket is fixedly mounted on outside spherical tank.
The present invention has the following technical effect that
Using method of the invention, either insulation blanket or strip, it can produce once and be used for multiple times, save material
Material.And due to being prefabricated steel, production and application is all very convenient, and speed of application is fast.The present processes install insulation blanket it
Afterwards, insulation blanket can be effectively fitted in outside spherical tank, and heat insulation effect is good.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of prefabricated strip；
Fig. 2 is combination scheme of installation of the strip on spherical tank；
Fig. 3 is spherical tank insulation blanket scheme of installation.
Specific embodiment
Following further describes the present invention with reference to the drawings.
Spherical tank is heat-treated insulation blanket installation method, comprising:
Firstly, requirements of one's work are heat-treated according to spherical tank, and in conjunction with the size of spherical tank, the strip 1 of prefabricated fixed insulation blanket, in advance
The strip of system, which can be combined according to strip using position, to form top manhole annular fixing belt steel and lower part manhole annular fixes
Strip, broadwise annular fixed strip, radial ringed fixed strip；
As shown in Fig. 1, the both ends of the strip 1 are provided with the hole 2 for installing fixing bolt, can according to need progress certainly
The length for increasing strip by combination, meets the needs of different size spherical tank；
On strip, the equidistant bolt 3 being welded with for fixing insulation blanket, and it is configured with nut 4 and compress gasket 5.
Secondly, after strip is made, by strip in the upper lower manhole outer wall of spherical tank, equatorial zone and other broadwises annular
Band is combined, and forms the fixed strip of cricoid broadwise, including top manhole annular fixing belt steel 11, the fixed strip of broadwise annular
12, the fixed strip 13 of equatorial zone annular, lower part manhole annular fixing belt steel 14, meanwhile, also installation forms annular radially
Radially fixed strip 15, the fixed strip of broadwise and radially fixed strip constitute fenestral fabric, as shown in Fig. 2.
Finally, insulation blanket 6 is mounted on the bolt on the strip of fenestral fabric, by compress gasket, with bolt pressure
Tightly, so as to which insulation blanket to be fixedly mounted on outside spherical tank wall 7, as shown in Fig. 3.
