Abstract

The utility model relates to a crater antiseptic butt joint pipe, which solves the problem of that the inner surface of the exiting pipeline welding opening is eroded. The crater antiseptic butt joint pipe is characterized in that; a stainless steel short connection (2) with a slope opening chamfering on one end is welded on the welded seam (4) point of two ends of a steel pipe body (1), and an inner antiseptic layer and an outer antiseptic layer (3, 5) are coated on the steel pipe body (1), the stainless steel short connection (2) and the inner wall and the outer wall of the welded seam (4). A pipe line which is made of the crater antiseptic butt joint pipe has better antiseptic effect and long service life, and the working efficiency of the petroleum production can be improved in the process of petroleum production for three times.

Description

The anticorrosion butt tube of weld bond
Technical field:
The utility model relates to the used a kind of butt tube of ground, oil field transfer line technical field, belongs to the anticorrosion butt tube of a kind of weld bond.
Background technique:
Ground, oil field is used for transferring oil, water, the pipeline of media such as gas, mostly be common steel tube easily by oil, water, dielectric corrosions such as gas, corrosion in the pipeline weld bond is the most serious, never method solves, because during the field welding construction, the pipeline internal surface scribbles the counterpart place of anticorrosive coat, because high temperature is born in the welding part, the destroyed inefficacy of the anticorrosive coat that is coated with, cause pipeline weld bond internal surface metal itself to expose out the corrosion-resistant effect that do not have, polymer flooding particularly, the pipeline that ternary composite driving is used, the iron ion at weld bond place entered in the polymer after the weld bond place was corroded, and depolymerization is caused inject the fluid viscosity reduction.Oil displacement efficiency is descended, influence the economic benefit of tertiary oil recovery.And the pipeline weld bond place leakage medium of boring a hole easily.
Summary of the invention:
In order to overcome the deficiency that existing pipeline weld bond place internal surface is corroded, the utility model provides a kind of weld bond anticorrosion butt tube, and the pipeline corrosion protection that the anticorrosion butt tube of this weld bond is made is effective, and long service life can improve oil extraction operation efficient in tertiary oil recovery.
The technical scheme in the invention for solving the technical problem is: the anticorrosion butt tube of this weld bond comprises the steel pipe main body, steel pipe main body two ends weld joint is welded with the stainless steel short circuit that an end has the groove chamfering, and steel pipe main body, the inside and outside wall of stainless steel short circuit and weld joint scribble inside and outside anticorrosive coat.
Above-mentioned steel pipe main body is connected by friction welding with the stainless steel short circuit.
The beneficial effects of the utility model are: owing to take the steel pipe main body two ends friction in the such scheme to be welded with the stainless steel pipe nipple that an end has groove, and carry out preservative treatment at weld bond, again pipeline is made in the butt joint of the beveled end of stainless steel pipe nipple, the weld bond place is the stainless steel body like this, the stainless steel corrosion resistance is strong, effectively prolong the working life of pipeline, reduced cost of production, increased the business economic benefit.
Description of drawings:
Fig. 1 is a structure half sectional view of the present utility model.
1-steel pipe main body among the figure, anticorrosive coat in the 2-stainless steel pipe nipple, 3-, 4-weld seam, 5-external anti-corrosion layer.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the anticorrosion butt tube of this weld bond comprises steel pipe main body 1, the friction of steel pipe main body 1 two ends weld seam 4 places is welded with stainless steel short circuit 2, in steel pipe main body 1, stainless steel short circuit 2 and weld seam 4 place's inwalls are coated with H88, cement mortar, epoxy resin etc. carry out preservative treatment for the interior anticorrosive coat 3 of anti-corrosion material, scribbling pitch at the outer surface of the anticorrosion butt tube of this weld bond is that the external anti-corrosion layer 5 of anti-corrosion material carries out preservative treatment, be to adopt first postwelding preserving method, anticorrosive paint can not be subjected to the destroyed inefficacy of high temperature meeting like this, effectively play the corrosion-resistant effect, and stainless steel short circuit 2 one ends have groove, adopt of the beveled end butt joint of stainless steel welding technique with stainless steel short circuit 2, the body of postwelding pipeline all scribbles anti-corrosion material like this, jointing is the stainless steel body, the stainless steel corrosion resistance and good, solved pipeline interface place internal and external anti-corrosive problem, the pipeline made from this short circuit can transferring oil, water, various medium senses such as gas, and when transferring polymer, can not enter into polymer because of not corroding iron ion, viscosity to polymer can not impact, and makes tertiary oil recovery everything goes well with your work to carry out.
This shows, the pipeline that uses the anticorrosion butt tube of this weld bond to make, can carry various media, be applied to every field, and the pipeline long service life has reduced cost of production effectively, has increased economic benefit of enterprises, particularly in the tertiary oil recovery process to the conveying of polymer, improved oil recovery efficiency.
