Product Description

1/16"~1" OD A789 SS Hydraulic Control Line Tubing Duplex 2205


Control line is normally used to operate surface controlled subsurface safety valves. Tiptop specializes in providing control lines that can meet the specific requirements of each customer. The control line with ASTM specifications can be offered in wide range of metallurgies. Encapsulated control line is also available which can improve the crush and abrasion resistance of the control line. Encapsulated control line is available in several configurations and materials to suit the customers' special requirements.


Control line uses seamless welded stainless steel, duplex and nickel alloy tubing to protect electrical and optical components from the pressure and corrosive effects of the downhole environment. Our company specializes in producing Capillary tubing(Control line tube) , is your reliable supplier.

The 3/8” hydraulic control line tubing is mainly used to inject chemicals into oil and gas wells. The 3/8” hydraulic control line tubing is connected to the downhole chemical injection valve. And the descaling agent is injected through the 3/8” hydraulic control pipeline and the chemical injection valve from the ground into the downhole tubing so as to make the oil and gas fields produce normally.


It can also be used for pressure control of surface safety valves and other surface valves, as well as connecting lines for instrumentation control systems of large oil and gas field drilling and oil extraction equipment.
