Super Duplex Stainless Steel 2507 Seamless Stainless Steel Hydraulic Tubing
Since 1999, Meilong Tube Co., Ltd. has produced both long coils and straight length of stainless steel and high nickel alloy tubing for numerous oil and gas applications, including hydraulic power, monitoring and control equipment, instrumentation, injection lines, down-hole safety valve control, subsea umbilical applications. Unique manufacturing capabilities and processes allow Meilong to produce the longest continuous length control line tubing available in stainless steels and high nickel alloys.
Our coiled tubing is available in a number of high performance corrosion resistant stainless steels and high nickel alloys, including 300 series, Incoloy, Inconel, capable of withstanding a variety of severe environmental conditions.
We specialize in manufacturing small diameter tubing ranging from 0.125 inch to 1 inch outside diameter (3.18mm to 25.4 mm) and a variety of wall thickness. Besides straight length instrumentation tubing, tubing is level wound coiled on various size spools, and products are tested and evaluated for specific applications before delivery. Our engineering staff welcome the opportunity to work with customers to solve special problems.
Meilong takes special care during manufacturing to assure ID and OD cleanliness of instrumentation tubing. Vacuum annealing insures volatility of metallic oxides and removal of any residual degreasing solvents or drawing lubricants. Vacuum annealing our stainless steel tubing insures a bright, cosmetically appealing surface as well as excellent mechanical properties.
Meilong commitment to quality excellence
From the time an order is received, sent through the production process, completed, and finally shipped, many levels of inspection occur to reinforce Meilong’s Quality Policy. The job of ensuring quality products extends as far as our machine operators. Meilong operators take ownership over material processed at their stations by measuring for dimensional accuracy and conducting a visual inspection of every piece.
Non Destructive Tests:
Positive Material Identification (PMI)
Stainless steel tubes are delivered in straight lengths
Steel grades ensures high corrosion resistance
