Abstract
The invention discloses a petroleum pipeline connecting piece having an anti-corrosion function, which comprises a connecting piece body (1), and is characterized in that: an anti-corrosion protecting layer (2) is arranged on the outer surface of the connecting piece body (1), the anti-corrosion protecting layer (2) comprises a fiberglass framework (3), a silicate mineral layer (4) is arranged on the fiberglass framework (3), and the thickness D of the anti-corrosion protecting layer (2) ranges from 4mm to 6mm. The petroleum pipeline connecting piece has a simple structure, an ingenious design, good corrosion resistance and high mechanical strength, and the service life can be prolonged.
Description
Technical field
The present invention relates to a kind of petroleum pipeline, especially a kind of be provided with corrosion protective covering at outer surface.Can prevent effectively that pipe joint is corroded, the petroleum pipeline link that increases the service life.
Background technique
In petroleum chemical industry; Need utilize a large amount of pipelines to carry out the transportation of oil; These pipelines then need use various pipe joints to be interconnected: like valve sleeve, pipe box, elbow cover etc., and mostly traditional pipe joint is steel design, and on its surface metallic material such as galvanized sheet iron, aluminium sheet, corrosion resistant plate is set and carries out anticorrosion; And these anticorrosion structures mostly exist the shortcoming that mechanical strength is low, heat conductivity is high; Simultaneously these anticorrosive coats in use for some time, deterioration phenomenon is serious, the leakage accident that causes because of corrosion happens occasionally; Therefore what needs were regular overhauls and safeguards these corrosion-prone parts, has improved the operation cost of petrochemical enterprise.Therefore need a kind of nonpetroleum pipe joint that can address the above problem now.
Summary of the invention
The present invention is in order to solve the above-mentioned deficiency of existing in prior technology, proposes a kind of simple in structurely, designs ingeniously, and antiseptic property is good, and mechanical strength is high, the petroleum pipeline link that increases the service life.
Technical solution of the present invention is: a kind of petroleum pipeline link with corrosion proof function; Comprise link body 1; It is characterized in that: the outer surface of described link body 1 is provided with corrosion protective covering 2; Corrosion protective covering 2 comprises glass fibre framework 3, on glass fibre framework 3, then is provided with silicate mineral layer 4, and the span of the thickness D of corrosion protective covering 2 is: the 4-6 millimeter.
The present invention compares with existing technology, has following advantage:
The petroleum pipeline link of this kind of structural type, it is simple in structure, and is reasonable in design; It is better that it has increased one deck mechanical mechanics property at the outer surface of traditional pipe joint, and the higher corrosion protective covering of anticorrosive property, and this corrosion protective covering is made up of glass fibre framework and silicate mineral layer; This corrosion protective covering does not burn; Can not produce any harmful gas, "dead", and the good insulation performance performance is arranged; And can be high temperature resistant, anti-freeze thawing, Safety performance is better; Also have performances such as waterproof, protection against the tide simultaneously, can not expand the situation of distortion.Therefore we can say that this petroleum pipeline link has possessed multiple advantage, be particularly suitable in petroleum chemical industry, applying that its market prospects are comparatively wide.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment
Below with accompanying drawings embodiment of the present invention.As shown in Figure 1: a kind of petroleum pipeline link with corrosion proof function; Comprise link body 1 (described link body 1 can be petroleum pipelines such as valve sleeve, pipe box, elbow cover links commonly used); Outer surface at link body 1 is provided with corrosion protective covering 2; This corrosion protective covering 2 comprises a glass fibre framework 3, and it then is provided with silicate mineral layer 4 as the basis of supporting corrosion protective covering 2 on glass fibre framework 3; The span of the thickness D of corrosion protective covering 2 is the 4-6 millimeter, is optimum value with 5 millimeters.
The petroleum pipeline link with corrosion proof function of the embodiment of the invention can be widely used in fields such as petrochemical industry, electric power, metallurgy, heating, and it has long working life and good corrosion resistance.
