L290Q oil and gas industrial pipelines are pipelines used to transport oil, natural gas and water at high temperatures, because of its excellent high temperature resistance and physical properties can withstand the harsh environment of high temperature and high pressure. And L290Q seamless steel pipes can be improved by surface coating for corrosion resistance.
Therefore, L290Q high-strength steel pipes are mainly used to transport fluid media such as natural gas, oil, water, and can also be used in chemical and power industries.
