Description
Technical field
The utility model belongs to large pressurized vessel, heat exchange equipment manufacturing field, is related to equipment pressure testing.
Background technique
Heat exchanger is one of the core equipment in oil refining, chemical industry and new energy device in addition to reactor.China exists in recent years
Dynamics of investment increases in the construction of projects such as large size oil refining, large-scale coal chemical industry, big ethylene, and scale is also increasing.In its manufacture
Carrying out pressure testing in the process is an indispensable important procedure.In pressure testing, prior art operation is typically all to try
There are 10 ~ 20mm pressure testing surpluses for aluminium hydraulic pressed connecting pipe length direction, in equipment pressure testing, according to adapter tube and exterior tubing connectivity port thickness
Select the pressure testing head of same diameter and thickness.In this way, the pressure testing head of configuration is all thicker, the cost of technique materials is opposite to be increased
Add；Cause welding workload big, wlding expends big；Therefore it certainly will increase workload, human cost is also increase accordingly；Very without
Ji.
Summary of the invention
Goal of the invention: pressure testing surplus need to be considered by overcoming prior art pressure testing adapter tube to order material, and end socket pressure testing materials are thicker, waste
Greatly, the biggish defect of welding workload.
The utility model provides a kind of equipment pressure testing adapter tube, and pressure testing head connecting pin is arranged in pressure testing adapter tube processing and forming
Mouth 2, either forging and stamping or Vehicle Processing, adapter tube ontology 1 and its external pipeline connection groove and pressure testing head connectivity port 2 are primary
Molding, the two are an entirety；The outer diameter and thickness of the pressure testing head connectivity port 2 are less than pressure testing adapter tube ontology 1, full
It is the smaller the better under the premise of sufficient pressure test pressure requires.
The pressure-measuring method taken over using the pressure testing of this equipment:
Selection or production pressure testing head 3, according to equipment take over determined blank, 2 actual size of pressure testing head connectivity port,
Three aspects of equipment hydraulic test pressure comprehensively consider determining pressure testing head size, port span and thickness, outer diameter and thickness
It is adapted with pressure testing head connectivity port 2；
Will take over ontology 1 be connected with apparatus casing welding and qualification of detecting a flaw, equipment be integrally heat-treated；
Pressure testing head connectivity port 2 and pressure testing head 3 are welded to connect；
Equipment integrally carries out the water pressure test after flaw detection is qualified；
Pressure testing head gas cutting line is marked from 3 side of pressure testing head after the water pressure test is qualified, cuts off simultaneously molten slag removal, note by line
Meaning protection adapter tube ontology preserves from；
Boring machine processing removes pressure testing head connectivity port 2, and adapter tube ontology 1 is made to meet design size；Position is removed to processing
Flaw detection, reaches the requirement of equipment and technology condition, and pressure testing process is completed.
The utility model has abandoned prior art pressure testing adapter tube and has ordered the method for expecting need to consider pressure testing surplus, and ingenious application is new to be thought
Road, new construction, the beneficial effect is that:
1, it can guarantee that equipment adapter tube opening groove during pressure testing is intact, it is small to damage to apparatus body；
2, this configuration reduces end socket wall thickness, save the end socket technique materials used time；
3, using this materials in vitro connection pressure testing head is taken over, it is not necessarily to height of nozzle direction made allowance, saves adapter tube material
Cost；
4, corresponding welding workload is reduced, and is reduced using wlding, and time cost shortens, time saving and energy saving material-saving.
5, easy to operate, securely and reliably, avoid adapter tube ontology due to welding the latent defect that may cause.
Detailed description of the invention
The big adapter tube of Fig. 1 heavy wall and pressure testing head attachment structure schematic diagram；
It include: 1 adapter tube, 2 pressure testing head connectivity ports, 3 pressure testing heads in figure.
Specific embodiment
The utility model is further described in conjunction with attached drawing.
As shown, providing a kind of equipment pressure testing adapter tube, pressure testing head connecting pin is set in pressure testing adapter tube processing and forming
Mouth 2, either forging and stamping or Vehicle Processing, adapter tube ontology 1 and its external pipeline connection groove and pressure testing head connectivity port 2 are primary
Molding, the two are an entirety；The outer diameter and thickness of the pressure testing head connectivity port 2 are less than pressure testing adapter tube ontology 1, full
It is the smaller the better under the premise of sufficient pressure test pressure requires.
The pressure-measuring method taken over using the pressure testing of this equipment:
Selection or production pressure testing head 3, according to equipment take over determined blank, 2 actual size of pressure testing head connectivity port,
Three aspects of equipment hydraulic test pressure comprehensively consider determining pressure testing head size, port span and thickness, outer diameter and thickness
It is adapted with pressure testing head connectivity port 2；
Will take over ontology 1 be connected with apparatus casing welding and qualification of detecting a flaw, equipment be integrally heat-treated；
Pressure testing head connectivity port 2 and pressure testing head 3 are welded to connect；
Equipment integrally carries out the water pressure test after flaw detection is qualified；
Pressure testing head gas cutting line is marked from 3 side of pressure testing head after the water pressure test is qualified, cuts off simultaneously molten slag removal, note by line
Meaning protection adapter tube ontology preserves from；
Boring machine processing removes pressure testing head connectivity port 2, and adapter tube ontology 1 is made to meet design size；Position is removed to processing
Flaw detection, reaches the requirement of equipment and technology condition, and pressure testing process is completed.
The utility model is suitable for large pressurized vessel pressure testing, without saving adapter tube, envelope in height of nozzle direction made allowance
Head material cost and welding cost guarantee quality, easy to operate, securely and reliably.
