Description
Technical field
The present invention relates to the production technology of jacketed vessel, specially a kind of inner cylinder be internal groove jacketed vessel production and
Pressure-measuring method.
Background technique
Jacketed vessel is first category vessel common in pressure vessel manufacturing, and general jacketed vessel need to carry out pressure testing three times, i.e.,
After inner cylinder welding, after the weldering of collet group and after equipment integral assembly welding, but the knot special due to jacketed vessel
Structure, each nozzle of equipment unsuitable groups of openings pair before collet group is soldered and finishes, but inner cylinder pressure testing need to carry out before collet group is welded, to weld
Stitch unqualified repairing.As equipment need inner cylinder close up mouth using if internal groove can not welding production, this results in jacketed vessel
Pressure testing is different from other generic containers.
Specifically, each interface on inner cylinder can effectively improve the quality of connection of adapter tube using inner slope mouth structure, in turn
The total quality of container is improved, but current processing, pressure-measuring method determine that inner cylinder must there are the processing of an outer groove
Hole is passed in and out for weld job personnel, so that the promotion of container total quality be made to be restricted.In conclusion needing to study a kind of collet
The processing of container and pressure-measuring method, in order to the pressure testing of inner cylinder and collet when jacketed equipment production.
Summary of the invention
The present invention is that can not all be processed into internal groove there are inner cylinder in the current jacketed vessel manufacturing process of solution to cause to hold
Device welding quality is difficult to the technical issues of being promoted, and provides production and the pressure-measuring method of the jacketed vessel that a kind of inner cylinder is internal groove.
The present invention is achieved by the following technical scheme: a kind of inner cylinder is the production and pressure testing of the jacketed vessel of internal groove
Method includes the following steps: that (1) prepares to open the hole that a bore is opened less than manhole in the position of manhole in advance, inner cylinder on the inner cylinder
Remaining interface tube is also fabricated to internal groove；Welding is grouped to inner cylinder, and the arc plate that pre-drilled cavity leaves is existed from outside weldings
At pre-drilled cavity, aperture connection water injection pipe and pressure gauge on arc plate carry out pressure testing to inner cylinder；
(2) collet and inner cylinder set are installed, continues to process bore in the position of pre-drilled cavity greater than pre-drilled cavity and is internal groove
Manhole carries out the pressure testing after the weldering of collet group；
(3) equipment integral assembly welding is carried out, the group pair including the welding of manhole connecting pipe and other adapter tubes that carry out inside inner cylinder
Welding；Pressure testing after integral assembly welding.
The method of the invention is passed in and out by opening a hole in advance on the inner cylinder for welding personnel, in this way can be first by arc plate
It is welded on completion pressure testing at pre-drilled cavity, reprocesses out final manhole later, and welding personnel can be in inner cylinder interior welds people
Adapter tube on hole guarantees that the total interface of inner cylinder is internal groove, effectively increases the welding quality of container.
A hole is pre-machined out and carries out pressure testing, the underproof interface of weld seam can also be repaired, while not shadow
Subsequent welding process is rung, the welding quality of manhole below will not be influenced.This method is used for jacketed vessel in the production process
Pressure testing, be not only convenient for jacketed equipment pressure testing, but also assembling sequence will not be changed, guarantee the production quality of equipment.
Strong operability of the present invention can process weldering suitable for the pressure testing for the jacketed vessel that inner cylinder is internal groove as required
It stitches groove and completes pressure testing, while not influencing process and other production processes, improve equipment making efficiency and quality, can be used for
Inner cylinder is the pressure testing and production of the jacketed vessel of internal groove.
Detailed description of the invention
The present invention is further described with example with reference to the accompanying drawing.
Fig. 1 is pressure-measuring method jacketed equipment schematic diagram of the present invention.
Figure middle cylinder body is stainless steel material, and inner cylinder internal diameter is DN1600mm, and wall thickness 16mm, manhole connecting pipe outer diameter is φ
530mm.Piece number 2 is inner cylinder, and piece number 3 is collet, and piece number 5 is manhole, and piece number 6 is adapter tube.
Fig. 2 is inner cylinder pressure testing structural schematic diagram, and piece number 1 is the pressure testing device (note installed on the arc plate left after aperture
Water pipe and pressure gauge), piece number 4 is pre-drilled cavity.
Specific embodiment
A kind of inner cylinder is production and the pressure-measuring method of the jacketed vessel of internal groove, includes the following steps: that (1) is quasi- on the inner cylinder
The hole that a bore is less than manhole is opened in the standby position for opening manhole in advance, remaining interface tube of inner cylinder is also fabricated to internal groove；To inner cylinder
Be grouped welding, and the arc plate that pre-drilled cavity is left from outside weldings at pre-drilled cavity, aperture connects water injection pipe on arc plate
And pressure gauge, pressure testing is carried out to inner cylinder；
(2) arc plate can retain, and can also remove, and collet and inner cylinder set are installed, and continue export processing in the position of pre-drilled cavity
Diameter is greater than pre-drilled cavity and is the manhole of internal groove, carries out the pressure testing after the weldering of collet group；
(3) equipment integral assembly welding is carried out, the group pair including the welding of manhole connecting pipe and other adapter tubes that carry out inside inner cylinder
Welding；Pressure testing after integral assembly welding.
The pre-drilled cavity internal diameter is 500mm, and manhole internal diameter is 530mm.
Collet and inner cylinder are stainless steel material, and inner cylinder internal diameter is DN1600, and wall thickness 16mm, manhole connecting pipe outer diameter is φ
530。
It is as shown in Figure 1 the structural schematic diagram of container, collet set portion outer tube, each adapter tube group is to finishing.At manhole
Connect the adapter tube of φ 530mm.
As shown in Fig. 2, according to the actual situation, take and pre-drilled cavity is carried out to manhole on collet inner cylinder, it will be on aperture backarc plate
Connection trial assembly is set, and arc plate (is connect water injection pipe and pressure in arc plate appropriate location according to the actual situation with welding at device aperture
Table), inner cylinder welding is first carried out, then carry out equipment group weldering in next step, to realize the pressure testing after inner cylinder welding, while can protected
Card equipment, which is respectively taken over, carries out welding after equipment inner/outer tube group is soldered and finishes, to guarantee equipment quality.
In traditional technology, if each pore of inner cylinder is all fabricated to internal groove, personnel will be each inside inner cylinder
It can not just be come out from inner cylinder after pore welding, it is therefore necessary to stay one to go out in the pore of outer groove for weld job personnel
Enter, but this just not can guarantee all internal grooves of all pores, can not improve the welding quality of container.Using of the present invention
After scheme, production and pressure testing are unaffected, while also ensuring that all pores of inner cylinder are internal groove, effectively increase weldering
Connect quality.
