Abstract
The utility model relates to a plastic -coated pipe of outer lining carbon steel ring, including plastic -coated pipe body, its characterized in that: still include carbon steel ring and sealing washer, the sealing washer suit in the mouth of pipe department at plastic -coated pipe body both ends, the welding has a carbon steel ring on the outer wall of the inside portion plastic -coated pipe body of sealing washer, carbon steel ring constitute by ring body and heat dam the system of circling in the ring body has the round to encircling outer sunken heat dam, this heat dam and the thermal -insulated district of the common formation of plastic -coated pipe body. The utility model discloses structural design scientific and reasonable has not and to lead to the fact destruction, increase of service life, convenient operation, leakproofness by force, effectively to prevent loss of property, to stop the advantage of potential safety hazard the body, is a plastic -coated pipe of outer lining carbon steel ring who has higher novelty.
Description
Technical field
This utility model relates to a kind of plastics coated tube, the plastics coated tube of a kind of outer lining carbon steel ring.
Background technology
Plastics coated tube is a kind of with welded tube, seamless pipe or galvanized pipe as base tube, applies one layer on its surface
The steel pipe of anti-rot plastic, which overcome steel pipe itself exist easily get rusty, burn into high pollution,
And plastic tube intensity defect low, yielding.Plastics coated tube is often used to the pipe as conveying gas
Road, such as natural gas, gas, biogas, coal gas etc..
When pipeline construction, need to weld many pipelines, and meeting during welding
Heating, thus the anti-rot plastic around weld seam can be destroyed, i.e. shorten the use of plastic-coated steel
Life-span；It addition, because this plastics coated tube is used for carrying gas, so the requirement to its sealing
Being the strictest, and existing plastics coated tube sealing after welding is poor, long-term pipeline is let out
Leakage not only can cause the loss of property, also can there is serious potential safety hazard.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that one has design department
Learn rationally, not to body damage, increase the service life, convenient operation, sealing is strong, have
Effect prevents property loss, stops the plastics coated tube of the outer lining carbon steel ring of potential safety hazard.
This utility model solves it and technical problem is that and take techniques below scheme to realize:
The plastics coated tube of a kind of outer lining carbon steel ring, including plastics coated tube body, it is characterised in that: also include
Carbon steel ring and sealing ring, described ring set is at the mouth of pipe at plastics coated tube body two ends, close
Being welded with carbon steel ring on the outer wall of the medial part plastics coated tube body of seal, described carbon steel ring is by ring body
And heat dam is constituted, the inner ring of described ring body is shaped with the heat dam that a circle caves in outside ring, should
Heat dam and plastics coated tube body are collectively forming thermal insulation areas.
And, described sealing ring is metallic graphite carbon sealing ring.
Advantage of the present utility model and good effect be:
1. the plastics coated tube of this outer lining carbon steel ring, welds carbon steel ring by the outer surface at original plastics coated tube,
Avoid, because of welding heating, the anti-rot plastic layer of its surfaces externally and internally is caused damage, extend plastic-coated
The service life of pipe；Simultaneously by the setting of heat dam on carbon steel ring, decrease carbon steel ring and plastic-coated
Heat transmission between pipe, is further ensured that the plastics coated tube quality when welding；It addition, by close
The setting of seal, enhances the sealing connected between two plastics coated tubes, and this weld seam is double with sealing ring
Seal structure so that the sealing property of this plastics coated tube is more superior, effectively prevent property loss and
Potential safety hazard.
2. this utility model scientific structure design is reasonable, has and does not damage body, extends use
Life-span, convenient operation, sealing by force, effectively prevent property loss, stop the advantage of potential safety hazard,
It it is the plastics coated tube of a kind of outer lining carbon steel ring with higher innovation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of reference numerals:
1-plastics coated tube body, 2-carbon steel ring, 3-heat dam, 4-sealing ring.
Detailed description of the invention
Below in conjunction with the accompanying drawings, by specific embodiment, the utility model is described in further detail.Following reality
It is illustrative for executing example, is not determinate, it is impossible to limit protection model of the present utility model with this
Enclose.
The plastics coated tube of a kind of outer lining carbon steel ring, including plastics coated tube body 1, its innovation is: also
Including carbon steel ring 2 and sealing ring 4, described ring set at the mouth of pipe at plastics coated tube body two ends,
The outer wall of the medial part plastics coated tube body of sealing ring is welded with carbon steel ring, described carbon steel ring by
Ring body and heat dam 3 are constituted, and be shaped with on the inner ring of described ring body that a circle caves in outside ring is heat insulation
Groove, this heat dam and plastics coated tube body are collectively forming thermal insulation areas.
Described sealing ring is metallic graphite carbon sealing ring.
This utility model welds carbon steel ring by the outer surface at original plastics coated tube, it is to avoid because of welding
Generate heat and the anti-rot plastic layer of its surfaces externally and internally is caused damage, extend the service life of plastics coated tube；
Simultaneously by the setting of heat dam on carbon steel ring, decrease the heat between carbon steel ring and plastics coated tube and pass
Pass, be further ensured that the plastics coated tube quality when welding；It addition, by the setting of sealing ring, increase
The sealing connected between strong two plastics coated tubes, the double sealing structure of this weld seam and sealing ring so that
The sealing property of this plastics coated tube is more superior, effectively prevent property loss and potential safety hazard.
Although disclosing embodiment of the present utility model and accompanying drawing for the purpose of illustration, but this area
Those of skill will appreciate that: without departing from this utility model and spirit and scope of the appended claims
In, various replacements, to change and modifications be all possible, therefore, and scope of the present utility model not office
It is limited to embodiment and accompanying drawing disclosure of that.
Claims (2)
