Abstract
The invention discloses a pipe nipple assembly of a thermal compensation petroleum pipeline. The pipe nipple assembly comprises a steel pipeline, an outer sleeve and a pipe nipple, and is characterized in that threads are arranged at two ends of the pipe nipple; the pipe nipple is provided with a blind hole; the pipe nipple is additionally arranged on the steel pipeline; the outer sleeve sleeves the outer side of the pipe nipple; heat insulating layers are arranged on the outer surface of the pipe nipple and the inner surface of the outer sleeve; and the pipe nipple is connected with a turbo type flow meter. The pipe nipple assembly of the thermal compensation petroleum pipeline has the characteristics of simple structure and firmness in connection.
Description
Technical field
The invention belongs to petroleum pipeline technical field, more particularly to a kind of thermal compensation petroleum pipeline deferent pipe nipple component.
Background technology
At present, both at home and abroad in the production operation that oil gas field oil pipe is removed, the position for confirming tubing nipple is by operator
Range estimation confirms that positioning tubing nipple position is inaccurate, causes tubing nipple position deviation, and the operating position for causing tubing tongs occurs
Change, it is impossible to realize that oil pipe removes the automation of production, production efficiency is affected, need to ask this for the technician
Topic is improved.
The content of the invention
It is contemplated that overcoming the defect of prior art, there is provided a kind of thermal compensation petroleum pipeline deferent pipe nipple component, with knot
Structure is simple, the characteristics of firmly connection.
In order to solve above-mentioned technical problem, the present invention provides technical scheme below：
A kind of thermal compensation petroleum pipeline deferent pipe nipple component, including steel conduit, overcoat, pipe pipe nipple, it is characterised in that pipe pipe nipple two ends
Screw thread is provided with, pipe pipe nipple is provided with blind hole, pipe pipe nipple is added on steel conduit, pipe pipe nipple outside is socketed with overcoat, manages short
Section outer surface has thermal insulation layer with overcoat inner surface setting, and on pipe pipe nipple turbine meter is connected with.
Further, the overcoat is circular arc and rectangular configuration combination, and overcoat is that spheroidal graphite cast-iron casting is formed.
Further, pipe pipe nipple outside is provided with bar stock.
Compared with prior art, the present invention has following beneficial effect：
Present configuration is simple, is skillfully constructed, and can realize that two pipelines firmly connect, when pipe pipe nipple is used, the connection of pipe pipe nipple
There is turbine meter in real time to be measured the flow in pipeline.
Description of the drawings
Fig. 1 is the schematic diagram of the overcoat of thermal compensation petroleum pipeline deferent pipe nipple component of the present invention.
Fig. 2 is the structural representation of thermal compensation petroleum pipeline deferent pipe nipple component of the present invention.
Specific embodiment
The preferred embodiments of the present invention are illustrated below in conjunction with accompanying drawing, it will be appreciated that preferred reality described herein
Apply example and be merely to illustrate and explain the present invention, be not intended to limit the present invention.
As shown in Figure 1 and Figure 2, a kind of thermal compensation petroleum pipeline deferent pipe nipple component, including steel conduit 1, overcoat 2, pipe pipe nipple 3,
The two ends of pipe pipe nipple 3 are provided with screw thread, and pipe pipe nipple 3 is provided with blind hole, and pipe pipe nipple 3, the outside of pipe pipe nipple 3 are added on steel conduit 1
Overcoat 2 is socketed with, the overcoat is circular arc and rectangular configuration combination, and overcoat is that spheroidal graphite cast-iron casting is formed.Outside pipe pipe nipple 3
There is thermal insulation layer 4 on surface with the inner surface setting of overcoat 2, and on pipe pipe nipple turbine meter is connected with.The outside of pipe pipe nipple 3 is provided with bar
Shape handle.
Explanation embodiments of the present invention are the foregoing is only, the present invention is not limited to, for the technology of this area
For personnel, all any modification, equivalent substitution and improvements within the spirit and principles in the present invention, made etc. should be included in
Within protection scope of the present invention.
