The main function of the coiled tubing is to transport the control liquid, which is used to regulate the pressure, flow rate and temperature of the oil well, which can realize the real-time monitoring and regulation of the environment of the wellbore, and improve the controllability and success rate of the downhole operation. MTSCO can provide 304/316/2205/alloy 625/825 and other materials.

Cost-effective, high-precision solutions for oil and gas transmission and structural engineering.

Electric resistance welded pipe (ERW) is a cost-effective choice in modern industrial pipeline systems, widely used in the fields of oil and gas transmission and structural engineering. The manufacturing principle utilizes the skin effect of high-frequency current to instantly heat the edge of the steel strip to a molten state, and fuse and connect it under the action of the extrusion roller. This process does not require the addition of filler metal, achieving atomic level bonding between the weld and the base metal.

EFW pipe refers to the process of using Electric Fusion Welding to roll stainless steel or nickel alloy steel plates into pipes and weld them along longitudinal seams. Compared with ERW (resistance welding), EFW is suitable for thick walled and large-diameter pipelines, with complete weld penetration and high strength.

Manufacturing standards: ASTM A358 or ASTM A671/A672, etc.

Core advantages: Strong adaptability to large caliber, Low cost, The structural strength meets the pressure bearing requirements, Strong corrosion resistance.

Application

Oil and natural gas: used in oil and gas gathering and transportation pipelines, refinery process pipelines, and has been applied in refinery projects in the Middle East and South America;

Chemical and paper-making: Suitable for transporting acidic and alkaline media, connecting pipelines to reaction vessels, and withstanding high temperature and high pressure conditions;

Desalination of seawater: As the main pipeline for seawater transportation, it is resistant to corrosion in the marine environment;

Power engineering: used for steam pipelines and cooling water systems in thermal power plants.
