MTSCO has been supplying industrial tubing to the heat exchanger/ oil and gas industry for more than a decade. In recent years, we have continued to make breakthroughs in the field of coiled tubing, downhole control lines, and chemical injection control lines. Our coiled tubing has been successfully used in kinds of heat exchanger, certain harsh subsea and downhole conditions, and through continuous research and development, is able to meet the stringent quality requirements of the heat exchanger industry and other industries.
