Abstract
The utility model discloses a kind of forging tubular construction with needing bore hole after high pressure single case weld, mainly it is made up of forging pipe, high pressure single housing, first formed by forging pipe with high pressure single case weld, after the completion of welding, only bottom bore hole need to be carried out in forging pipe, then Welded Joints carry out Non-Destructive Testing, and detection is qualified can to ensure welding point complete penetraction and fusion in welding, ensure welding quality.This novel forging tubular construction, have and save precious materials；Processing capacity is small, that is, reduces equipment manufacturing costs, in turn ensure that welding point complete penetraction and fusion in welding, ensure that welding quality, avoids triggering security incident.
Description
Technical field
Individual layer high pressure vessel is the utility model is related to, after specially a kind of and individual layer high pressure vessel case weld
The forging tubular construction of bore hole is needed, suitable for chemical industry high-pressure bottle.
Background technology：
Maximization and high parameter with pressure vessel, to ensure the security reliability of high-pressure bottle, managed frequently with forging
With carrying out bore hole after high pressure single case weld, ensure welding point complete penetraction and fusion in welding, ensure welding quality, at present forging pipe and high pressure list
The forging tubular construction of bore hole is needed after layer case weld, as shown in Fig. 2 having the following disadvantages：1st, it is consistent to forge bore, all bore holes
Preceding size, especially forging pipe is precious metal, and substantial amounts of waste of material is caused after bore hole；2nd, forging pipe and high pressure single case weld
Afterwards, whole bore holes need to be carried out by Fig. 1 forging bores, processing capacity is big, causes unnecessary manpower consumption and equipment loss, and increase is set
Standby manufacturing cost.Therefore, it is necessary to a kind of forging tubular construction for reducing manpower and waste of material.
The content of the invention
The utility model is that tube material and manpower waste and processing capacity is big in order to solve the problems, such as to forge, there is provided Yi Zhongyu
The small forging tubular construction of bore hole amount is needed after the welding of individual layer high pressure vessel.
The utility model adopts the following technical scheme that realization：
A kind of forging tubular construction with needing bore hole after high pressure single case weld, including forging tube body, the forging tube body lead to
The flange for crossing its lower end is assemblied at the mouth of pipe of high pressure single housing and is welded to connect, and the forging tube body upper inner diameter is bore hole
Size, lower inner diameter are size before bore hole afterwards, and the lower inner diameter of the forging tube body is less than the spout diameter of high pressure single housing.
Before welding job, by forging pipe according to pipe upper inner diameter is forged as size after bore hole, lower inner diameter is size before bore hole,
The requirement that lower inner diameter is less than upper inner diameter is processed, and the purpose so forged is to after forging pipe is with case weld, forge
Pipe top does not have to carry out Boring again, reduces labor content；Forging pipe bottom is welded with high pressure single housing afterwards
Connection, because after bore hole, forging pipe bottom should be the same with the internal diameter size on top, so, it is necessary to be managed to forging after the completion of welding
The opening part of bottom, weld part and housing carries out bore hole, and after bore hole terminates, Welded Joints carry out Non-Destructive Testing, and detection is closed
Lattice can ensure welding point complete penetraction and fusion in welding, ensure welding quality.
The utility model reduces the workload of bore hole, reduces manpower consumption and equipment loss, reduces device fabrication
Cost；Guarantee welding point complete penetraction and fusion in welding is reached again, ensure that the quality of welding, overcome the deficiencies in the prior art；When forging is managed
For precious metal when, substantial amounts of waste of material will not be caused.
Brief description of the drawings
Fig. 1 is cross-sectional view of the present utility model.
Fig. 2 is the forging tubular construction schematic diagram before improving.
Fig. 3 is forging tubular construction schematic diagram of the present utility model.
In Fig. 1：1- forges tube body, 2- high pressure single housings, 3- weld parts, 11- flanges.
Embodiment
Specific embodiment of the utility model is illustrated below in conjunction with the accompanying drawings.
A kind of forging tubular construction with needing bore hole after high pressure single case weld, as shown in figure 1, forging tube body 1 is by under it
The flange at end is assemblied at the mouth of pipe of high pressure single housing 2 and is welded to connect, and forging tube body 1 upper inner diameter is chi after bore hole
Very little, lower inner diameter is size before bore hole, and the lower inner diameter of the forging tube body 1 is less than the spout diameter of high pressure single housing 2.
Forging pipe described in the utility model forges according to the structure shown in Fig. 3, will in order to reduce processing capacity and waste of material
Forging pipe upper inner diameter is designed as size after bore hole, and the forging lower inner diameter of pipe 1 is designed as size before bore hole, forges the top and the bottom length ratio of pipe
Example is 2:1~3:1.In the present embodiment, the two radius difference 8mm, i.e. bore hole thickness is 8mm；Welding when, will forging pipe lower end with
High pressure single case weld, ensure welding quality；Then bore hole is carried out, only need to be by forging pipe bottom, unnecessary solder joint and housing
Thickness machines away in bore hole, the housing spout diameter after processing and the internal diameter all same of forging pipe top and the bottom, saves processing capacity
And manpower consumption.Last Welded Joints carry out Non-Destructive Testing, and detection is qualified can to ensure welding point complete penetraction and fusion in welding, ensure welding
Quality, avoid triggering security incident.
Exemplary description is carried out to the utility model above in conjunction with accompanying drawing, it is clear that the utility model concrete implementation is not
Limited by aforesaid way, if the various improvement that methodology and technical scheme of the present utility model are carried out are employed, or not
Improved directly application and other occasions, in the scope of protection of the utility model.
