Abstract
The utility model relates to an use high -pressure oil and gas separator, in particular to anticorrosive entry pipe connecting device that is used for high -pressure oil and gas separator. The device's entry takeover upper end welding inlet flange welds stainless steel ring shape circle on the stainless steel barrel body, in the stainless steel barrel body inserting the takeover that enters the mouth, stainless steel ring shape circle articulated on the inlet flange up end, and the packing has the fluid sealant between the external wall of stainless steel barrel and entry takeover and the inlet flange inner wall, is equipped with down the insulating blanket between stainless steel ring shape circle and the inlet flange up end, and the fluid sealant upper end is arranged in to lower insulating blanket. The utility model discloses an adopting the stainless steel inner tube in the entry is taken over, making oil -gas mixture fully collided, the medium that enables to reflect again can not corrode to enter the mouth to be taken over and the flange face, guarantees the equipment safe operation, fills the insulating layer simultaneously between entry takeover and stainless steel inner tube, avoids xenogenesis steel direct contact to produce galvanic corrosion.
Description
Technical field:
This utility model relates to a kind of oil field high-pressure oil gas separator, particularly to a kind of anticorrosive inlet connection device for high-pressure oil gas separator.
Background technology:
The visual plant that gs-oil separator produces as oil gas field, applies relatively wide in oil-gas field surface engineering, and its internal structure is mainly made up of entrance separating head, corrugated plating group and exit mesh demister.Xinjiang tooth is breathed out in oil field shaft mouth Produced Liquid containing cl-, H2The eroded elements such as S, the inlet connection inwall of existing high-pressure oil gas separator due to the high speed of corrosive medium wash away, collision impact effect, thorn leakage often occurs, and the medium in gs-oil separator is inflammable and explosive product, as processed not in time, can be dangerous.Inlet connection inwall and flange and adapter junction seriously corroded is found after stop production to overhaul, there is erosion vestige, other positions are intact in equipment, analyze reason, it is considered to be primarily due to that medium inlet pressure is big, speed fast, medium interreflection is washed into and causes inside adapter.
Causing stopping production, clear tank, the get angry new inlet connection of welding and flange if as local corrosion, such workload is very big, causes waste, and two is that whole equipment causes stopping production transformation without other corrosion phenomenons, the simple corrosion because of local, is also uneconomic.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of anticorrosive inlet connection device for gs-oil separator, the arrangement achieves employing rustless steel inner core in inlet connection, gas mixture is made fully to be collided, the dielectric corrosion reflected can be made again less than inlet connection and flange face thereof, ensure equipment safety operation, between inlet connection and rustless steel inner core, fill insulating barrier, it is to avoid dissimilar steel directly contacts generation galvanic corrosion simultaneously.Overcome existing gs-oil separator inlet connection and deficiency that flange face is easily corroded.
Technical solution adopted in the utility model is: a kind of anticorrosive inlet connection device for gs-oil separator, including inlet connection, inlet connection lower end is welded in equipment barrel；Inlet connection upper end welding inlet flange, stainless steel cylinder upper end soldering stainless steel annular ring, stainless steel cylinder inserts in inlet connection, rustless steel annular ring is articulated on inlet flange upper surface, it is filled with fluid sealant between stainless steel cylinder outer wall and inlet connection and inlet flange inwall, equipped with lower insulating blanket between rustless steel annular ring and inlet flange upper surface, lower insulating blanket is placed in fluid sealant upper end, shut by epoxy coating bottom stainless steel cylinder and between inlet connection lower end inner wall, rustless steel annular ring upper end is provided with insulating blanket, upper insulating blanket upper end is provided with technique adapter flange, it is bolted between technique adapter flange and inlet flange, technique adapter flange upper end Joining Technology adapter.
The beneficial effects of the utility model are: this utility model uses rustless steel inner core in inlet connection, gas mixture is made fully to be collided, the dielectric corrosion reflected can be made again less than inlet connection and flange face thereof, ensure equipment safety operation, between inlet connection and rustless steel inner core, fill insulating barrier, it is to avoid dissimilar steel directly contacts generation galvanic corrosion simultaneously.
Accompanying drawing illustrates:
The utility model is described in more detail with detailed description of the invention below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
As it is shown in figure 1, a kind of anticorrosive inlet connection device for gs-oil separator, including inlet connection 1, inlet connection 1 lower end is welded in equipment barrel 2；Inlet connection 1 upper end welding inlet flange 6, stainless steel cylinder 5 upper end soldering stainless steel annular ring 10, stainless steel cylinder 5 inserts in inlet connection 1, rustless steel annular ring 10 is articulated on inlet flange 6 upper surface, it is filled with fluid sealant 4 between stainless steel cylinder 5 outer wall and inlet connection 1 and inlet flange 6 inwall, one is to play fixation, also avoids dissimilar steel directly to contact simultaneously.Equipped with lower insulating blanket 9 between rustless steel annular ring 10 and inlet flange 6 upper surface, it is to avoid dissimilar steel directly contacts, produce galvanic corrosion.Lower insulating blanket 9 is placed in fluid sealant 4 upper end, is shut by wear-resisting epoxy coating 3 bottom stainless steel cylinder 5 and between inlet connection 1 lower end inner wall, it is to avoid medium penetrates into and causes corrosion.Rustless steel annular ring 10 upper end is provided with insulating blanket 12, and upper insulating blanket 12 upper end is provided with technique adapter flange 11, is connected by bolt 7 between technique adapter flange 11 and inlet flange 6, technique adapter flange 11 upper end Joining Technology adapter 8.
It is understandable that, above with respect to specific descriptions of the present utility model, it is merely to illustrate this utility model and is not limited to the technical scheme described by this utility model embodiment, it will be understood by those within the art that, still this utility model can be modified or equivalent, to reach identical technique effect；Needs are used, all within protection domain of the present utility model as long as meeting.
