Rura stalowa kompozytowa mechaniczna

In the exploitation process of domestic oil and gas fields with high hydrogen sulfide and high carbon dioxide, ordinary carbon steel pipelines are difficult to meet the demand of oil and gas transportation because of their insufficient corrosion resistance; Although the pure stainless steel pipeline is corrosion-resistant, its high price has greatly increased the cost. In this context, the development and application of oil and gas pipelines with low cost, corrosion resistance and excellent performance is of great significance to promote the efficient and economic development of the oil and gas industry. In line with this trend, a series of composite pipe products such as mechanical composite steel pipe came into being. mechanical composite steel pipes are mainly manufactured according to international standards such as API 5LD and DNV OS F101.

Excellent corrosion resistance: mechanical composite steel pipe can effectively resist the corrosion of various chemicals, especially suitable for complex working conditions of conveying corrosive media. This feature not only ensures the stable operation of the pipeline in harsh environment, but also greatly prolongs the service life of the pipeline and reduces the maintenance and replacement costs.

Perfect combination of high strength and toughness: mechanical composite steel pipe has a high-strength structure, which can withstand greater pressure and external force, and ensure the safe operation of the pipeline under severe conditions such as high pressure and heavy load. At the same time, on the basis of ensuring good corrosion resistance, the inner metal also provides certain toughness, further enhancing the impact resistance of the pipeline, enabling it to cope with various emergencies and effectively improving the reliability of the pipeline system.
