Description
Technical field
The present invention relates to a kind of pipe connecting structure, specifically a kind of continuous reinforced plastic composite pipe joint structure.
Background technique
Liquid substance and the oil well produced petroleum of oil exploitation will converge and be transported to multi-purpose station, and oil well produced petroleum contains more
There is corrosion valence matter, for majority to prevent petroleum is sticky from needing to heat it in favor of flowing conveying, it is using steel that the past is usually mostly
Pipeline, laying steel pipe construction workload is long in time limit greatly, and the steel pipe poor corrosion resistance service life, short flow resistance loss was big, heat
Loss is big, oil transportation cost is high, then it is thought that continuous reinforced plastic composite pipe, i.e., high pressure resistant and anti-corrosion, and good heat insulating,
Liquid flow resistance is small, and the theoretical service life was up to 30 years or more.
The bottleneck that current plastic composite pipe promotes and applies is that the structure type of pipe joint is difficult to meet application, and majority uses
The outer cuff structure of internal expanding, shortcoming are cannot to be squeezed stress when connector is just carried out in plastics directly in conjunction with enhancement layer
Lower and internal expanding head and outer bundle hoop are acted on into binding force, pipe joint is linked together with pipeline, over time, modeling
Expect that yield stress disappears, binding force reduces, and especially plastics soften when conveying high temperature petroleum, and connector and pipeline lose combination
Power, gently then then pipe fitting is pushed out causes the accident under stress oil leak weight, to sum up states reason plastics steel interlining composite pipes not yet
It is used widely in oil transportation.
It is investigated from data, currently, connection of the plastic composite pipe joint of maturation as plastic composite pipe not yet both at home and abroad
Mode.Although there is producer using internal expanding outer hoop structural union, it is not so good as people's will more.

Portion compresses between, and spiral fastening squeezes the inner conical surface for being equipped in inner conical drogue and matching with tapered squeezing end male cone (strobilus masculinus),
Spiral fastening squeezes inner conical drogue and tapered squeezing end is steel, and bearing course is the netted braiding of steel wire or steel strip winding structure.
As further scheme of the invention: the spiral fastening squeezes the male cone (strobilus masculinus) of inner conical drogue and tapered squeezing end
Thickening is handled at cooperation.
As further scheme of the invention: the plastics steel interlining composite pipes plastic conduit further includes protective layer, is prevented
Sheath is arranged at the position on bearing course in addition to squeezing clamping section.
As further scheme of the invention: the protective layer is adopted made of plastic.
As further scheme of the invention: being equipped with the platform abutted against with basal layer end face in the tapered squeezing end
Rank.
As further scheme of the invention: being also equipped with sealing ring between the basal layer and tapered squeezing end.
Compared with prior art, the beneficial effects of the present invention are: by the bearing course of plastics steel interlining composite pipes plastic conduit
It is linked together with the tapered squeezing end of steel by the clamping of metal contact squeeze, what this connection type was not plastically deformed by plastics
It influences, is not also influenced by temperature, stable connection bonding strength is high, it is ensured that the service life of many decades, and this structural joint
Without inner core, tapered squeezing end internal diameter is identical with plastics steel interlining composite pipes plastic conduit internal diameter, pumped (conveying) medium non-resistance, it will
Oil transportation cost is substantially reduced, the security reliability of oil transportation is improved.
Detailed description of the invention
