Example Embodiment

[0025] Example 1. 10 parts of natural rubber and 80 parts of regenerated rubber were masticated, and then 1.0 part of accelerator TMTD, 0.5 part of sulfur and 65 parts of asphalt were added and mixed thoroughly, and then kneaded to produce an anticorrosive tape.

Example Embodiment

[0026] Example 2. 10 parts of natural rubber and 80 parts of regenerated rubber were masticated, and then 1.2 parts of accelerator TMTD, 2.5 parts of sulfur and 80 parts of asphalt were added and mixed thoroughly to form an anticorrosive tape.

Example Embodiment

[0027] Example 3. An anticorrosive belt is prepared by masticating 10 parts of natural rubber and 80 parts of regenerated rubber, adding 1.5 parts of accelerator TMTD, 4.0 parts of sulfur, and 50 parts of asphalt, and mixing them thoroughly.

Abstract

The invention relates to an anticorrosive pipe and relative producing method. It is purposed to solve the problems of present technique with high cost, and worse anticorrosive effect. The invention is characterized in that the producing method comprises following steps: (1) making the pipe line needed anti-corrosion reach Sa2.5 level via shot-blast de-rusting or sandblast de-rusting and removing surface dust; (2) plating adhesive agent on the pipe line to be dried naturally; (3) coiling anticorrosive belt and draw belt on the pipe line; (4) processing steam sulfuration in 130-140Deg.C for 15-25 minutes to prepare said anticorrosive pipe. The invention has lower producing cost, better anticorrosive effect and simple process.

Description

Technical field: [0001] The invention relates to an anti-corrosion pipe used for oil (gas) transportation in the oilfield field and a manufacturing process thereof. Background technique: [0002] At present, in the field of pipeline anti-corrosion, especially in the field of oil and gas gathering and transportation pipelines on the surface of oil fields, the anti-corrosion pipelines used are still mainly traditional petroleum asphalt pipes, modified asphalt anti-corrosion pipes and epoxy coal tar anti-corrosion pipes. Later, glass steel pipes appeared , polyethylene tape anti-corrosion pipe, etc., these products have exposed some problems in practical applications, such as high energy consumption, environmental pollution, and cannot meet the needs of the complex geographical environment of the oil field, especially in recent years. cost issue. Invention content: [0003] The purpose of the present invention is to solve the problems of high cost and poor anticorrosion effe...
