A789 2507/2205 Bright Annealed Duplex Steel Instrument Geothermal Coiled Tubing
MTSCO has been supplying geothermal coiled tubing to the oil and gas industry for more than a decade. We mainly supply materials of stainless steel, duplex steel and nickel alloy (such as 304/L,316/L, 2205, 2507,alloy 625, alloy 825). Diameters from 4mm to 25mm and our length can be up to 33000ft (10000m). It 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 oil industry. This type of geothermal coiled tubing can also be processed to encapsulated tubing to meet customer requirements.
