Abstract
The utility model is related to a kind of elbow connection pipe parts of monoblock type reduced pipe comprising reduced pipe and elbow；It is characterized in that reduced pipe and elbow form for solid forging, the inside junction of reduced pipe and elbow is arc-shaped linkage section.The utility model has the advantages that security risk can be reduced and improves service life.
Description
Technical field
The utility model is related to a kind of elbow connection pipe part more particularly to a kind of elbow connection pipes of monoblock type reduced pipe
Part.
Background technology
Currently, the elbow connection pipe part of high temperature and pressure reduced pipe is the dedicated spy of extra large work drilling platforms oil recovery high pressure pipe joint
High pressure forging pipe fitting, is widely used in conveying liquid, in the pipe network of the media such as gas, is mainly used for the shunting to medium and steering,
As shown in Figure 1 comprising reduced pipe 1 and elbow 2, reduced pipe 1 and elbow 2 are welded into one the two using the pattern of welding, so
Weld stress is eliminated by heat treatment afterwards, though this structure can effectively ensure the connection of pipeline and the circulation of medium, welding
Place's intensity is not high, and there are security risks；And there is a straight linkage section 3 in the inside junction of reduced pipe 1 and elbow 2, herein by
The impact force arrived is larger, and long-term impact may cause to deform, and influence the conveying of medium.Elbow is circulation medium corner,
It is the weak link of entire pipeline, elbow inner arc side is area of stress concentration, and outer arc side is then seawater worn area, in pressure piping
During gas collection, corroded by medium inside pipeline, under fluid dynamics factor effect, generates serious erosion damage, it is right
The abrasion of elbow outer arc side is especially serious, and existing elbow is usually what outer arc was thinned in forming process, and intensity is not high,
The accident of perforation, leakage and cracking most easily occurs under the erosion damage of high-pressure fluid medium, therefore there are serious security risks.
Invention content
For disadvantage mentioned above, security risk and raising service life can be reduced the purpose of this utility model is to provide a kind of
Monoblock type reduced pipe elbow connection pipe part.
The technology contents of the utility model are a kind of elbow connection pipe part of monoblock type reduced pipe comprising reduced pipe and
Elbow；It is characterized in that reduced pipe and elbow form for solid forging, the inside junction of reduced pipe and elbow is arc-shaped connection
Section.
The utility model is compared with prior art advantageously：The reduced pipe of the utility model is directly adopted with elbow
It is process with solid forging mode, increases integral thickness so that structural strength higher, and there is no attachment weld, reduced pipe
Junction with elbow is arc-shaped, has good smoothness, flow of media resistance is small, to strengthen the circulation of medium
Property, and it has been greatly reduced the impact force to transition region, security risk is reduced, service life is improved.Outside due to elbow
Arc is the region for wearing most serious by seawater scouring, therefore on the basis of meeting pipeline strength grade, elbow integral thickness
Increase the wearability for also enhancing elbow back.
Description of the drawings
Fig. 1 is the structural schematic diagram of the elbow connection pipe part of existing reduced pipe.
Fig. 2 is the structural schematic diagram of the utility model.
Specific implementation mode
As shown in Fig. 2, a kind of elbow connection pipe part of monoblock type reduced pipe comprising reduced pipe 4 and elbow 5；Its feature
It is that solid forging forms for reduced pipe 4 and elbow 5, the inside junction of reduced pipe 4 and elbow 5 is arc-shaped linkage section 6.
Claims (1)
1. a kind of elbow connection pipe part of monoblock type reduced pipe comprising reduced pipe and elbow；It is characterized by reduced pipe and elbow
It is formed for solid forging, the inside junction of reduced pipe and elbow is arc-shaped linkage section.
