Stainless Steel Hydraulic Control Tubing is a mainstream product of Hydraulic Control Capillary Tubing series, widely adopted in downhole hydraulic drive control systems for oil & gas wells. We are capable of manufacturing tubing in diverse specifications and dimensions as required by clients. Standard products are produced in strict accordance with ASTM A269 standards, and customized non-standard solutions are available. Adopting seamless precision stainless steel forming technology, the tubing features uniform wall thickness and high pressure resistance, suitable for harsh downhole environments with high temperature, hydrogen sulfide and carbon dioxide corrosion. It is usually laid together with High Temperature Steel Tube Cable, and forms integrated downhole measurement and control systems with Well Logging Cable. Deployed downhole synchronously with Composite Coiled Tubing Cable for long-term dynamic monitoring, it cooperates with ESP Submersible Pump Cable to realize coordin…
