Meilong Tube specializes in the production of seamless and redrawn, welded and redrawn coiled tubing, which are made from corrosion-resistant austenitic, duplex, super duplex stainless steels and nickel alloy grades. These products are mostly used in oil and gas, geothermal industries as hydraulic control lines and chemical injection lines. The tubing coils feature high length without orbital welds, and thus reduces possibilities of potential defects or failures. Furthermore, these coils have a very clean and smooth interior surface, giving them a unique advantage in chemical injection systems, as they offer short hydraulic response time, greater collapse strength, and the elimination of methanol permeation.
Duplex 2205 is a type of nitrogen-enhanced and duplex stainless steel that was created to withstand against corrosion, compared to the usual 300 series stainless steels. The structure of 2205 consists of austenite pools that are surrounded by a continuous ferrite phase. In the annealed condition, Duplex 2205 contains around 40-50% ferrite. Often termed as a work horse grade, it is the most widely used type in the entire duplex family of stainless steels.
The characteristics of 2205 stainless steel are its efficacy to combat corrosion, stress corrosion cracking resistance and high strength, and its ease of fabrication and corrosion resistance. Its usage must be within the temperatures of 600° F. If exposed to a temperature higher than this limit, the stainless steel has a chance to be embrittled. The properties of corrosion resistance are owed to the high content of chromium, molybdenum and nitrogen present in it.
Due to its excellent corrosion resistance, 2205 duplex stainless steel is a cost-effective solution for applications which the 300 series stainless steels are susceptible to chloride stress corrosion cracking. In addition to marine environment and brackish water, it is also used in bleaching operations, closed loop water systems and some food processing applications.
Each one tubing coil is a single, unbroken piece without any orbital welds. To ensure its quality, each coil is put through a hydrostatic pressure test at a minimum of 10,000 psi. A third-party inspector from certified bodies like SGS, BV, or DNV can be requested to witness the testing process. Other tests that we carry out are eddy current, chemical, flattening, flaring, tensile, yield, elongation, and hardness tests.
At Meilong Tube, we take special measures to make sure that both the inner and the outer surfaces of our control lines and chemical injection lines are clean and free of residue. We adopt a vacuum annealing process to evaporate toxic metallic oxides and eliminate any lingering degreasing solvents and drawing lubricant. This process further improves the aesthetics and mechanical properties of our alloy tubing.
