The hydraulic control line is the another name for Capillary tubes, which is mainly used for oil and gas field underground capillary pressure measurement. . It can also be used for pressure control of surface safety valves and other surface valves, and various connection pipelines of large-scale equipment instrumentation control systems for oil and gas field drilling and oil production.
316/316L is the most commonly used austenitic stainless steel in the chemical process industry. The addition of molybdenum increases general corrosion resistance, improves chloride pitting resistance and strengthens the alloy in high temperature service. Through the controlled addition of nitrogen it is common for 316/316L to meet the mechanical properties of 316 straight grade, while maintaining a low carbon content.
