Hydrostatic test for each coil and conform to ASTM standards and requested specifications.


The specification and length per coil can be customized according to customer’s requirements.



Tiptop is specialized in providing alloy steel coiled tube, alloy steel control line, alloy steel continuous tube.


Seamless control lines are used in SCSSV, Chemical Injection, and Advanced Well Completions. Seamless tubes provide another tubing solution for our customer's complex well designs. The most common uses for Seamless line tend to be shorter length applications whereby no orbital welds are required.


Type 625 Alloy (UNS Designation NO6625) is an austenitic nickel-based super alloy possessing excellent resistance to oxidation and corrosion over a broad range of corrosive conditions, including jet engine environments and in many other aerospace and chemical process applications. The alloy has outstanding strength and toughness at temperatures ranging from cryogenic temperature to 2000°F (1093°C). Type 625 alloy also has exceptional fatigue resistance. It derives its strength from the solid solution strengthening effects of molybdenum and columbium on the nickel-chromium matrix. Although the alloy was developed for high temperature strength, its highly alloyed composition provides a high level of general corrosion resistance to a wide range of oxidizing and non-oxidizing environments.


1/4”Hydraulic control line, mainly used for the control of downhole safety valve and gas release valve of cable packer in oil and gas wells. The 1/4 “hydraulic control tubeline is connected to the downhole safety valve and gas valve, and the on-off pressure of the oil and gas well downhole safety valve and the gas release valve through the cable packer are controlled by ground pressure. After the set pressure is reached, the oil and gas well is downhole. The safety valve and the gas release valve passing through the cable packer are opened at the same time. At this time, the oil and gas well can be normally produced, and the gas separated by the electric submersible pump can also be discharged from the annulus through the gas release valve. Then, the pressure of the control tubeline is released, so that the downhole safety valve of the oil and gas well and the gas release valve passing through the cable packer are closed at the same time, and the oil and gas well oil tubes and annulus circulation channels are all blocked, so that the safety of the oil well can be ensured. Of course, the 1/4” hydraulic control line can also be used alone for the control of downhole safety valves.


It can also be used for pressure control of surface safety valves and other surface valves, and various connection tubelines of large-scale equipment instrumentation control systems for oil and gas field drilling and oil production.
