Description
Technical field
The utility model is related to tubing fields, more particularly, to a kind of inner coating chemical proof floor pipeline.
Background technology
Currently, the characteristics of petrochemical pipe is that medium internal corrosion is serious, the breakage of especially oil field oil pipeline causes
Crude oil is revealed, and causes environmental pollution, the wasting of resources, and composite bimetal pipe of high cost, pipeline in the application of oil field ground pipeline
Between weld seam be easy leakage, be not used widely in oil field ground pipe engineering.Solution the most universal is using interior
The antisepsis oil pipe of coating, but internally coated antisepsis oil pipe be used as surface line when, since it is desired that often dismounting, installation, commonly
Box cupling and its inconvenience；Moreover, at common box cupling, perishable, insufficient strength, leakage accident frequent occurrence.
Invention content
The purpose of this utility model is that solve the deficiencies in the prior art, and inner coating chemical proof floor pipeline is provided.This
The new technical solution of utility model is：Inner coating chemical proof floor pipeline, including tube body, steel joint A, steel joint B, connection
Cap, described tube body one end connect steel joint A, and the other end connects steel joint B；Interior one end of the steel joint A is set
It is equipped with sealing ring, external screw thread is provided on the outside of the steel joint A, boss is provided in the middle part of the steel joint B,
The attachment cap is located at the outside of steel joint B, and the internal diameter of attachment cap one end is less than the outer diameter of boss, the other end of attachment cap
Internal diameter be more than boss outer diameter, inside is provided with internal thread corresponding with external screw thread, phase is provided among the inside of attachment cap
Should fluted B be set in the groove A of boss, the outside of attachment cap；The inside of the tube body, steel joint A, steel joint B
It is coated with one layer of corrosion-inhibiting coating.
The corrosion-inhibiting coating is using epoxy anticorrosion layer, Vinylidene Chloride erosion resistant coating, chlorinated rubber erosion resistant coating, polyurethane anticorrosion
Layer, acrylic acid erosion resistant coating, inorganic anti-corrosion layer or highly-chlorinated polyethylene erosion resistant coating.
The outside of the attachment cap is evenly arranged with 6 groove B for one week.
The utility model has the beneficial effects that：Corrosion condition at the common internal coating tubing box cupling of effective solution increases
The strong intensity of joint, reduces leakage accident, meanwhile, the easily removable installation of connector is very convenient.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the attachment cap of the utility model.
Wherein：1 is steel joint A, and 2 be steel joint B, and 3 be attachment cap, and 4 be tube body, and 5 be corrosion-inhibiting coating, and 6 be sealing
Circle, 7 be external screw thread, and 8 be internal thread, and 9 be boss, and 10 be groove A, and 11 be groove B.
Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
Inner coating chemical proof floor pipeline, including tube body 4, steel joint A1, steel joint B2, attachment cap 3, the tube body
