TP2205 features an austenite-ferrite duplex structure. Its 25% Cr + 5% Ni + 3% Mo composition provides excellent resistance to pitting and crevice corrosion in seawater and chloride-containing media. With a high yield strength about 1.8 times that of 304L, it maintains structural stability under medium-to-high pressure pulsating loads. This meets the long-term operational demands of marine engineering and desalination systems.
TP2205 duplex stainless steel seamless pipe combines the advantages of both austenite and ferrite structures. It offers superior resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Its high strength makes it excellent for lightweight designs. It also maintains good mechanical properties in both high and low-temperature environments. This pipe is especially suitable for marine environments with high chloride content, ensuring long-term stable operation.

2205 Seamless Pipe in Marine Industry
In the modern high-end marine industry, 2205 duplex stainless steel seamless pipes are becoming a key material for improving marine performance and service life. Faced with multiple challenges brought by seawater corrosion, structural lightweighting, and environmental regulations, the comprehensive advantages of 2205 are particularly prominent.
The strength of 2205 is about twice that of traditional 316L stainless steel, allowing for the use of thinner pipe walls while meeting safety standards, thereby reducing ship weight and fuel consumption. In terms of corrosion resistance, 2205 can effectively resist pitting corrosion and stress corrosion cracking caused by seawater.
Therefore, it is widely used in the most demanding marine systems, such as:
For sea LCL shipments, we use plywood wooden boxes with pipe caps. Full container loads are bundled with woven bags and also include pipe caps on both ends. All wooden boxes meet ISPM-15 standards, allowing direct entry into European and American automated warehousing systems. The anti-salt spray and anti-collision design ensures no rust or scratches on the surface after long-distance transport.
SMLSCO’s duplex steel TP2205 seamless pipe uses advanced manufacturing processes for superior quality. It starts with selecting high-quality steel billets. The pipe then undergoes precise piercing and multi-pass cold drawing or cold rolling to achieve exact dimensional tolerances and surface finish. A strict solution annealing treatment optimizes the material's crystal structure and mechanical properties. Finally, pickling and passivation enhance corrosion resistance, ensuring the product meets high-standard application requirements.
