Epoxy rubber: a major breakthrough in oil field pipeline corrosion

China's first modern professional vulcanized rubber line operations in recent days in the Shengli oil field oil companies to build the official opening of the operation and success of the first batch of prefabricated steel pipe. "Epoxy rubber" technology, marks China's oil fields in the research and application of new rubber pipe anti-corrosion technology was a major breakthrough.

Epoxy anti-corrosion steel, rubber pipe anti-corrosion technology is a cutting-edge nature of the world with a new type of anti-corrosion technology. It is the first anti-corrosion epoxy coating to protect, and then the use of renewable sources of tread rubber band wound, the pipeline will rust primer after brushing the rubber band wound in the pipe, through the steam curing technology in the steel pipe outside a certain The thickness of the layer of rubber so as to attain the anti-corrosion. Traditional oil and asphalt and coal tar pitch epoxy anti-corrosion technology By contrast, the new technology is not only good insulation, low water absorption, bonding in prison, a simple process, and steel tube with an external anti-corrosion layer forming beautiful, solid coating, the cost of production Low-benefit advantages, such as environmental protection, on behalf of the steel pipe outside the current anti-corrosion technology development trends, economic and social prospects.

Shengli oil field as early as the beginning of 2002 on the forward-looking aim at the subject, has invested enormous effort on research, scientific research and special projects. They are at home and abroad with many related technologies and comparative analysis of repeated research experiments, the successful production of rust, epoxy glue, winding, curing the "four-step" process of rubber anti-corrosion technology. This new type of rubber anti-corrosion technology of prefabricated steel tube, after a series of experimental technology program, has shown effective against external damage, erosion-resistant high-pressure-resistant, extend the use of pipe, and other obvious advantages.
