3 / 8 '' OD x 0.065 '' WT Cold Drawn Tube in Coils Hydraulic Control Line for Oil and Gas Wells
Meilong Tube supplies a whole range of hydraulic control line products to the oil and gas sector, and it’s one of our most important markets. You’ll find our high performance hydraulic line tubes successfully used in some of the most aggressive subsea and downhole conditions thanks to our proven track record in meeting the strict quality requirements of the oil, gas and geothermal energy industries.
Improving technology has extended the range of ways in which oil and gas fields can be exploited, and increasingly projects require the use of long, continuous lengths of stainless steel control lines. These are employed in a variety of applications including hydraulic controls, instrumentation, chemical injection, umbilicals and flowline control. Meilong Tube supplies products for all of these applications, and more, lowering operating costs and improved recovery methods for our customers.
Thanks to advances in tubular control line technologies, it is now cheaper and easier to connect downhole valves and chemical injection systems with remote and satellite wells, for both fixed and floating central platforms. We offer coiled tubing for control lines in stainless steel and nickel alloys.
