Abstract
The utility model relates to a penetration-proof carbon fiber compound pipe, which is composed of a carbon fiber compound pipe inner layer (1), semiarc-shaped steel pipes (2), a carbon fiber compound pipe outer layer (3), an outer thread (4) and an inner thread (5), wherein the penetration-proof carbon fiber compound pipe is formed through butting two semiarc-shaped steel pipes (2) whose radius is slightly bigger than that of the carbon fiber compound pipe inner layer (1), epoxy resin is filled between the steel pipes and the inner layer and between clearances which are formed through butting arcs, a penetration-proof layer is formed, carbon fiber is twisted around the surface of the pipe, and the outer thread (4), the inner thread (5) and the semiarc-shaped steel pipes (2) are welded into the pipe. The utility model has the advantages that the pipe is burglarproof and the pipe prevents the compound pipe from splitting on large area and prevents crude oil from flowing freely.
Description
One, technical field:
The present invention relates to the pipeline and the production technology thereof of a kind of oil field gathering and transportation, water filling.
Two, background technique:
Existing pipeline often occurs with pipeline boring, saw kerf or with after the strong acid corrosion, phenomenons such as the oil in theft oil field, gas.
Three, summary of the invention:
The purpose of this invention is to provide a kind of structure, technology is simple, the carbon fiber composite pipe that anti-penetration is strong.
Technological scheme:
A kind of anti-penetration carbon fiber composite pipe, form by carbon fiber composite pipe internal layer (1), half curved steel tube (2), carbon fiber composite pipe skin (3), outer screw thread (4), interior screw thread (5), it is characterized in that: the anti-penetration layer is formed by two and half curved steel tubes (2) butt joint that radius is slightly larger than carbon fiber composite pipe internal layer (1), to be full of between steel pipe and the internal layer and between the slit of arc butt joint by epoxy resin, form the anti-penetration layer, carbon fiber is twined on surface at pipe, and outer screw thread (4), interior screw thread (5) are welded into pipe with half curved steel tube (2).
Before forming the anti-penetration layer, outer screw thread (4) and half curved steel tube (2) welding, wherein twining (1) one of internal layer, will to be longer than the distance of steel pipe (2) be the length of outer screw thread (4).
After forming the anti-penetration layer, interior screw thread (5) and half curved steel tube (2) welding, wherein twining outer (3) distances that will be longer than the anti-penetration layer is the length of interior screw thread (5).
Have antitheft, prevent that the composite pipe large size from tearing the benefit that crude oil trickles everywhere.
Four, description of drawings:
Accompanying drawing is a structural representation of the present invention.
Carbon fiber composite pipe internal layer (1), half curved steel tube (2), carbon fiber composite pipe, outer screw thread (4), interior screw thread (5)
Five, specific embodiment:
The invention provides a kind of structure, technology is simple, the carbon fiber composite pipe that anti-penetration is strong.Be that the anti-penetration layer is welded by two and half curved steel tubes (2) that radius is slightly larger than carbon fiber composite pipe internal layer (1), epoxy resin will be full of between steel pipe and the internal layer and between the slit of arc butt joint, and carbon fiber is twined on the surface of pipe.
Outer screw thread (4), interior screw thread (5) are welded into pipe with half curved steel tube (2).
Wherein before forming the anti-penetration layer, outer screw thread (4) and half curved steel tube (2) welding, wherein twining (1) one of internal layer, will to be longer than the distance of steel pipe (2) be the length of outer screw thread (4).
After forming the anti-penetration layer, interior screw thread (5) and half curved steel tube (2) welding, wherein twining outer (3) distances that will be longer than the anti-penetration layer is the length of interior screw thread (5).
Claims (3)
1, a kind of anti-penetration carbon fiber composite pipe, form by carbon fiber composite pipe internal layer (1), half curved steel tube (2), carbon fiber composite pipe skin (3), outer screw thread (4), interior screw thread (5), it is characterized in that: the anti-penetration layer is formed by two and half curved steel tubes (2) butt joint that radius is slightly larger than carbon fiber composite pipe internal layer (1), to be full of between steel pipe and the internal layer and between the slit of arc butt joint by epoxy resin, form the anti-penetration layer, carbon fiber is twined on surface at pipe, and outer screw thread (4), interior screw thread (5) are welded into pipe with half curved steel tube (2).
2, anti-penetration carbon fiber composite pipe according to claim 1 is characterized in that: the welding of outer screw thread (4) and half curved steel tube (2), wherein twining (1) one of internal layer, will to be longer than the distance of steel pipe (2) be the length of outer screw thread (4).
