Abstract
The utility model relates to a welding seam X X -ray radiographic inspection technical field of boiler collection case pipe butt joint specifically be a collection case pipe box structure of detecting a flaw, and it can realize the safety inspection that album case was managed well, and it includes the transversal joint electrically welded tube, the taper joint of transversal joint electrically welded tube one end fixed connection, the other end are opened there is the installation breach, fixed mounting has the flange circle on the transversal joint electrically welded tube, the transversal joint electrically welded tube with the stereotype inoxidizing coating has all been wrapped up to the taper joint outside, the opening part fixed mounting of taper joint has the lead curtain fixed plate, install lead curtain on the lead curtain fixed plate.
Description
Technical field
This utility model relates to the weld seam x-ray inspection technical field of boiler header pipe docking, is specially a kind of header flaw detection sleeve pipe structure.
Background technology
Boiler by be filled with water produce steam pot with burning produce heat energy bench of burners become, burning heat energy pass to the water in pot, it is necessary to have enough conduct heat area, for expansion heat transfer area, shell boiler is developed into tubular boiler, to increase heat transfer area.Water in these tube banks constantly cyclic absorption heat energy separate vapour must concentrate at case (cylinder) top to vapour above, the water of bottom flows in following case (cylinder), and distribute to each heat restrained and continue in absorption furnace, when the weld seam x-ray inspection that boiler header pipe is docked, in original flaw detection lead room, detection casing inner diameter and detectable header maximum outside diameter are limited, during detecting a flaw, collecting box pipe easily and detects wall friction or collision in pipe box, causes damage.
Summary of the invention
In order to solve the problems referred to above, this utility model provides a kind of header flaw detection sleeve pipe structure, and it can realize the safety detection of collecting box pipe well.
Its technical scheme is such that a kind of header flaw detection sleeve pipe structure, it is characterized in that, it includes vertical masonry joint electrically welded tube, the fixing connection taper joint of described vertical masonry joint electrically welded tube one end, the other end have installation gap, it is installed with flange circle on described vertical masonry joint electrically welded tube, all being enclosed with stereotype overcoat outside described vertical masonry joint electrically welded tube and described taper joint, the opening part of described taper joint is installed with lead curtain fixed plate, and described lead curtain fixed plate is provided with lead curtain.
It is further characterized by, and described installation gap includes the big breach of subordinate's breach and bottom, and described taper joint openings of sizes is 30 °；
Described stereotype overcoat is stereotype thick for one layer of 16mm or the stereotype of two superimposed 8mm thickness together；
Described lead curtain is fixed in described lead curtain fixed plate by trim ring and the first bolt；
By the second bolt, annular stereotype is installed on described flange circle.
After using structure of the present utility model, having stereotype overcoat in vertical masonry joint electrically welded tube outer wrap, one end is fixedly connected with taper joint and is sealed by lead curtain, will not be with pipe box contact internal walls when pipe of detecting a flaw puts in, and effectively prevent radiation leakage, achieve the safety detection of collecting box pipe well.
Accompanying drawing explanation
Fig. 1 is this utility model structural front view；
Fig. 2 be in Fig. 1 A-A to sectional view.
Detailed description of the invention
See Fig. 1, shown in Fig. 2, a kind of header flaw detection sleeve pipe structure, it includes vertical masonry joint electrically welded tube 1, vertical masonry joint electrically welded tube 1 one end is fixing connects taper joint 2, the other end has installation gap, flange circle 3 it is installed with on vertical masonry joint electrically welded tube 1, by the second bolt, annular stereotype 4 is installed on flange circle 3, vertical masonry joint electrically welded tube 1 is outside with taper joint 2 is all enclosed with stereotype overcoat 5, stereotype overcoat 5 and vertical masonry joint electrically welded tube 1, overcoat 6 it is provided with between taper joint 2, flange circle 3 can ensure that the firm connection of stereotype overcoat 5, the opening part of taper joint 2 is installed with lead curtain fixed plate 7, lead curtain fixed plate 7 is fixed with lead curtain 9 by trim ring 8 and the first bolt.Installation gap includes the big breach of subordinate's breach and bottom, and taper joint 2 openings of sizes is 30 °；
Stereotype overcoat 5 is stereotype thick for one layer of 16mm or the stereotype of two superimposed 8mm thickness together.
