In summary, UNS S30900 pipes offer reliable strength and durability in challenging environments across various industries!
TP309 Stainless Steel Tubing are austenitic chromium-nickel ss that provide excellent corrosion resistance and heat resistance plus good strength at room and elevated temperatures. The lower nickel content of 309 tubes improves resistance to sulfur attack at high temperatures. The high chromium and nickel content of SUS 309 Pipe & tubes provides comparable corrosion resistance, superior resistance to oxidation, and the retention of a larger fraction of room temperature strength than the common austenitic 304.
The steel resists oxidation up to 1900°F (1038°C) under non-cyclic conditions
Because of its high chromium and low nickel content, 309 can be utilized in sulfur containing atmospheres up to 1832°F (1000°C). The steel is not recommended for use in highly carburizing atmospheres since it exhibits only moderate resistance to carbon absorption. 309 can be utilized in slightly oxidizing, nitriding, cementing and thermal cycling applications, albeit, the maximum service temperature must be reduced.
TP310 Seamless Stainless Steel Tube is engineered for exceptional performance in high-temperature and corrosive environments. Renowned for their superior resistance to oxidation and thermal fatigue, these tubes are ideal for demanding applications across various industries. ① STANDARD: ASTM A213/ ASTM A249/ ASTM A269/EN10216-5/ GOST 9940 /GOST 9941...② OD RANGE : 6-257MM③ THICKNESS RANGE: 1-35 MM
Seamless Stainless Steel U-tube is a specific type of heat exchanger tube that is bent into a"U"shape after the manufacturing process. It is crafted from a single, solid billet of stainless steel and, like other seamless tubes, has no weld joint. This seamless construction is crucial for maintaining structural integrity and reliability, especially in high-stress and corrosive environments. The unique U-shape allows for thermal expansion and contraction, making it ideal for shell and tube heat exchangers. It enables a single-pass fluid flow on the shell side and a multi-pass flow on the tube side, maximizing heat exchange efficiency and reducing the overall footprint of the heat exchanger.① STANDARD: ASTM A213② OD RANGE : 6-50.8MM③ THICKNESS RANGE: 0.5-9MM④ U-BEND & STRAIGHT
