Coil tube VS Straight tube

Increased corrosion resistance, thanks to stainless steel, duplex and nickel alloys properties.

Improved reliability—using fewer mechanical fittings or welds reduces the opportunity for defect, such as leaks and other long-term failures

Reduced installation labor costs—installing continuous length of tube takes less time and is more reliable than coupling multiple shorter lengths

Features: Alloy 825 has excellent resistance to chloride-ion-induced stress corrosion cracking, reducing environments containing phosphoric and sulfuric acids, oxidizing environments containing nitric acid and nitrates, and pitting, crevice corrosion and intergranular corrosion. It has good mechanical properties at cryogenic temperatures to moderately high temperatures up to 538℃.

Applications: Chemical process industry, acid production, pickling equipment, pollution control equipment.

An increasing number of projects in the oil service industry require the use of continuous lengths of nickel alloy capillary tube. They are used in a variety of applications, including chemical injection, hydraulic control, instrumentation umbilicals and flowline control. MTSCO offers products for all of these applications, helping customers reduce operating costs and improve recovery methods.
