Description
Technical field
This utility model relates to pipeline construction technical field, particularly a kind of foam glass insulation conduit saddle.
Background technology
According to the most domestic cold insulation pipe carrier. industry and domestic all of petrochemical industry and LNG liquefaction or the setting of receiving station
From the point of view of Ji, the conduit saddle of pipeline all uses high density PIR/PUR conduit saddle, and such conduit saddle has easy for installation, quick construction, the most extensively
General application.But according to 5.6.2 requirement in country GB 50160-2008, the load steel structure described in the 5.6.1 article following
Position should cover flame retardant coating, covers the steel construction of flame retardant coating, its fire endurance be not lower than 1.5h (appended word illustrates: this
In bar " load-bearing " concept for directly bearing equipment or pipeline weight), specification specify that the resistance to of the conduit saddle structure sheaf of weight bearing conduit
The fire limit is not less than 1.5h.The fire-protection rating of high density PIR/PUR being presently used in the conduit saddle of pipeline support is only capable of reaching B2
Level and do not possess the requirement of fire endurance, and during crossed construction, easily cause the fire that welding causes；It addition, use
In the adiabator contacted with austenitic stainless steel surface, its chloride, fluoride, silicate, the content of sodium ion, should meet
The pertinent regulations of existing international standard " Standard specification of thermal insulation materials for use over austenitic stainless steel " GB/T 17393, the pH of its leachate
Value should be 7.0-11.0 at 25 DEG C.To meet above-mentioned fire resistance rating and the PIR/PUR market of GB/T 17,393 two requirement simultaneously
Upper being difficult to meets.Another more serious problem is: on market, some manufacturer is in order to pursue the fire prevention etc. of high density PIR/PUR
Level, adds fire retardant in the feed, makes chloride ion content be multiplied, exist for from high density on stainless steel pipes surface
Chloride that PIR/PUR surface separates out and the stainless steel intercrystalline corrosion that causes of fluoride and stress corrosion, make stainless steel pipes
The essential safety hidden danger of Cheng Geng great.
Utility model content
The purpose of this utility model is to thoroughly solve fire-resistant, the cold insulation of cold insulation pipe carrier and the difficulty of precipitation chloride corrosion
Topic, and devise a kind of foam glass insulation conduit saddle.
Realizing above-mentioned purpose the technical solution of the utility model is, a kind of foam glass insulation conduit saddle, including bracket, bracket
On be placed with on the outer surface of stainless steel pipes, bracket and stainless steel pipes and be enclosed with foam glass layer, foam glass is a kind of
Being commonly used in the material of cold insulation system, this material heat conductivity at low temperatures is low, and foam glass is with glass as raw material, high
Temperature is melted post-foaming and is formed, and is consequently belonging to inorganic material, does not fires, and belongs to fire prevention A1 level, foam glass chloride ion pole
Low and meet water and will not separate out chloride, when contacting with stainless steel pipes, pipeline will not be produced intergranular and stress corrosion, bubble
Being enclosed with insulation material layer on foam glass layer, insulation material layer is provided with vapor stops with the contact site of bracket.
Described bracket convex shape bracket.
Described insulation material layer is wrapped with protection set.
Described protection set is fixedly sleeved on insulation material layer by tubular rivet.
Seam between the seam of described stainless steel pipes, stainless steel pipes and bracket and stainless steel pipes and foam glass
Seam crossing between glass layer all uses joint sealer to carry out vapour lock encapsulation process.
Described stainless steel pipes includes guiding stainless steel pipes and slip stainless steel pipes two kinds.
The foam glass insulation conduit saddle utilizing the technical solution of the utility model to make will substitute traditional high density
PIR/PUR conduit saddle, with more cost-effective ensure to realize conventional high-density PIR/PUR conduit saddle function while, it is ensured that it is whole
Individual conduit saddle system meets 5.6.2 requirement in GB 50160-2008, makes the fire endurance of pipeline bearing tube holder structure be not less than
1.5h, but also the mode of increase system insulation layer thickness can be taked to improve fire endurance easily according to formal testing result and reach
By 2 hours even 3 hours.Meanwhile, the fire prevention of conduit saddle heat insulation layer reach A level do not fire, without separate out chloride and fluoride and chlorine from
Sub-content meets the requirement of GB/T 17393.This utility model conduit saddle system is greatly improved the pipe of petrochemical industry and storage and handling facility
The fire savety of road supporting construction, postpones what Hydrocarbon fire extreme temperature caused by this utility model conduit saddle structure
Lost efficacy, and taked rescue measure to provide the more time for operator, thus farthest reduce the process pipe that fire causes
Property loss.
Accompanying drawing explanation
Fig. 1 is the structural representation of foam glass described in the utility model insulation conduit saddle；
In figure, 1, bracket；2, stainless steel pipes；3, foam glass layer；4, insulation material layer；5, vapor stops；6, protect
Sheath；7, tubular rivet.
Detailed description of the invention
Below in conjunction with the accompanying drawings to of the present utility model be rationally to be specifically described: if Fig. 1 is bubble described in the utility model
The structural representation of foam glass insulation conduit saddle, as it can be seen, a kind of foam glass insulation conduit saddle, including bracket 1, bracket is placed
Have on the outer surface of stainless steel pipes 2, bracket and stainless steel pipes and be enclosed with foam glass layer 3, foam glass layer is enclosed with
Insulation material layer 4, insulation material layer is provided with vapor stops 5 with the contact site of bracket.Wherein, described bracket 1 convex shape
Bracket；Described insulation material layer 4 is wrapped with protection set 6；Described protection set 6 is fixedly sleeved at heat insulating material by tubular rivet 7
On the bed of material；Seam between seam, stainless steel pipes and the bracket of described stainless steel pipes 2 and stainless steel pipes and foam glass
Seam crossing between glass layer all uses joint sealer to carry out vapour lock encapsulation process；Described stainless steel pipes 2 includes guiding stainless
Steel conduit and slip stainless steel pipes two kinds.
The feature of the technical program is interpolation foam glass layer between insulation material layer and stainless steel pipes, blocks thermal insulation
Contacting between material layer and stainless steel pipes.Ensure that its whole conduit saddle system meets 5.6.2 in GB 50160-2008 and wants
Ask, make the fire endurance of pipeline bearing tube holder structure be not less than 1.5h.Meanwhile, reach without separate out chloride and fluoride and chlorine from
Sub-content meets the requirement of GB/T 17393.
Technique scheme only embodies the optimal technical scheme of technical solutions of the utility model, the technology of the art
Some variations that some of which part may be made by personnel all embody principle of the present utility model, belong to this utility model
Protection domain within.
