Petroleum pipeline anti-corrosion

The commonly used anti-corrosion methods for well pipes include nitriding, hydrogen ring powder spraying, titanium nano spraying, carbon zirconium coating, PE pipe lining, fiberglass tubing, etc. The price of PE pipe lining is relatively high, which is difficult for the market to accept. Other anti-corrosion methods belong to low-end anti-corrosion technology, with unstable production and unsatisfactory anti-corrosion effects, lacking competitiveness. Fiberglass lined oil pipes have mature and reliable technology, moderate price, and strong market competitiveness. The anti-corrosion technology of fiberglass lining has the characteristics of lightweight, high strength, corrosion resistance, and is not corroded by oil, water, salt, and other media. Moreover, its water surface can reduce the adhesion of ground ions. At the same time, its internal surface is smooth, improving the flow state of the pipe and reducing the probability of scale crystals adhering to the pipe wall. Since its application in the inner lining of oil and gas equipment in the 1960s, it has been successfully applied in oil pipes, casings, gathering and transportation pipelines, reinjection pipelines, outlet pipelines, and pipelines.

Anticorrosive clock lining system:

The internal anti-corrosion lining system for oil field steel pipes and pipelines is manufactured using an embedded lining process using filament wound composite materials or extruded thermoplastic.

A corrosion-resistant material is formed inside the steel pipe, which can isolate corrosive liquids and gases used in oil from the steel pipe.

The replacement cost of damaged bottomhole production tubing or subsea flowlines is very high. Duole can provide excellent corrosion resistance protection in extremely harsh environments, which other products cannot. Compared to spray coatings with shorter durability, Duole not only has cost-effectiveness but also excellent performance at full moon. At present, high-performance systems are widely used in a wide range, and before that, in high-temperature or acidic bottomhole environments, people used low-cost corrosion-resistant alloys.

The product can be installed into threaded oil field fittings through almost any connection.
