Abstract
The invention provides an RTP pipe joint. The RTP pipe joint comprises a body composed of cylindrical left joints and cylindrical right joints. The outer ends of the left joints and the outer ends of the right joints are connected with left pipelines and right pipelines respectively, the inner ends of the left joints and the inner ends of the right joints are connection ends for connection of the left joints and the right joints, the diameter of the inner ends of the left joints is larger than that of the outer ends of the left joints, outward fastening sleeves are arranged at the inner ends of the left joints, male threads are arranged on the outer surfaces of the inner ends of the right joints, female threads are arranged on the inner sides of the right ends of the outward fastening sleeves, the male threads are meshed with the female threads, the outer surfaces of the outward fastening sleeves and the outer surfaces of the right joints are square, and the outer diameter of the outer surfaces of the right joints is larger than that of the outer ends of the corresponding left joints. The RTP pipe joint solves the problems existing in existing RTP pipeline connection and has the advantages of being high in connecting strength and good in sealing performance.
Description
Technical field
The present invention relates to a kind of pipeline connection area, particularly a kind of oil gas field composite material RTP joint.
Background technique
Strengthen thermoplastic composite tube (RTP, Reinforced Thermoplastic Pipes) usually primarily of three layers of formations, i.e. inside and outside plastic layer and be arranged on the enhancement layer that is composited by reinforcing material of centre.RTP has that bearing capacity is high, flexible, the feature such as easy of constructing, and application area is more and more wider, has been successfully applied to oil gas field field both domestic and external at present.
For RTP material, between tube and tube, usually adopting electric smelting--hot-melt adhesive paste is connected with mechanical compaction mode (withholding connection).There is the defects such as pipeline join strength is lower, sealing is poor in electric smelting hot-melt adhesive paste mode.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of RTP joint, to overcome the defect existed in prior art.
The present invention is achieved through the following technical solutions:
A kind of RTP joint, it is characterized in that: comprise the body be made up of columned left joint and right connector, wherein, the outer end of left joint is connected with right pipeline with left pipeline respectively with the outer end of right connector, the inner end of left joint and the inner end of right connector are respectively the interconnective connecting end of left and right joint
The inner end diameter of left joint is larger than the outer diameter of left joint, the inner end of left joint is provided with outer tight cover, the inner end outer surface of right connector has male thread, box thread is had inside outer tight cover right-hand member, described male thread is engaged mutually with box thread, the outer tight outer surface of cover and the outer surface of right connector are square, and the outer surface of right connector is larger than the external diameter of the outer end of corresponding left joint.
The internal surface that above-mentioned left joint is connected with left pipeline and the internal surface that right connector is connected with right pipeline are equipped with pawl.
The side of the inner end of above-mentioned left joint is provided with fluorine-containing packing ring.
The internal surface of left joint described above and right connector pipeline is equipped with corrosion-inhibiting coating.
The invention provides a kind of RTP joint, meet the problem that existing RTP line connects, have that join strength is high, the advantage of good airproof performance.
