2205 Material Properties
2205 duplex stainless steel combines the characteristics of austenitic and ferritic steels, with excellent strength and corrosion resistance. It has outstanding resistance to chloride ion stress corrosion, pitting corrosion, and crevice corrosion, making it very suitable for high salt, high pressure, and high temperature working conditions. In addition, 2205 has stable and reliable mechanical properties in high-pressure environments, and is widely used in industrial fields such as oil and gas, marine engineering, and chemical engineering that require strict material requirements.
2205 Application Scenarios
2205 thick walled duplex steel seamless pipes are widely used in offshore oil platforms, subsea pipeline systems, chemical plant pipelines, desalination units, heat exchangers, and high-pressure process pipelines. Especially suitable for high chlorine, high salt, and high-pressure environments, it performs excellently in extending pipeline service life and reducing equipment maintenance costs, and is highly trusted by global customers, helping enterprises achieve safe and efficient production and operation.
Advantages of SMLSCO Pipe:
SMLSCO has a long-term stock of over 2000 tons of seamless pipes, including TP2205 duplex steel thick walled pipes (Sch40), which can be shipped in as little as 2 weeks for regular specifications. Bulk procurement of high-quality raw materials such as TSINGSHAN effectively reduces overall costs; All products undergo strict three-level quality inspection and 100% shipment inspection, with stable and reliable product performance, and hold PED certification, meeting the global industrial customers' procurement needs for high quality, fast delivery, and low cost.
Inspection for SMLSCO Pipe:
To ensure the quality stability of TP2205 thick walled duplex steel seamless pipes, we use spectral composition analysis (PMI) to accurately detect the raw materials; Perform Eddy Current Testing during the production process to strictly control surface and internal defects; During the finished product stage, size measurement, hardness testing, liquid penetrant testing, and non-destructive testing (NDT) are implemented to ensure the reliability and safety of the pipeline.
