654SMO(EN 1.4652/UNSS32654) is a special stainless steel containing a high percentage of Nickel and Chromium containing 7% Molybdenum,which is the highest corrision restistance in the world.
It has a fairly high electrical conductivity among wrought superaustenitic stainless steels. In addition, it has the lowest thermal conductivity and very high tensile strength.
654SMo (S32654, 1.4652) super austenitic stainless steel features very good local corrosion resistance, good pitting resistance and good stress corrosion resistance under seawater, aeration, gap and low speed scouring conditions. It can be used as a good substitute to nickel-based alloys and titanium alloys. When it comes to high-temperature resistance or corrosion resistance, it is also superior to 904L and 254SMo.
TP347H Seamless Stainless Steel Pipe are high-performance austenitic stainless steel tubes stabilised with niobium, specifically designed for elevated temperature applications and enhanced creep resistance. ① STANDARD: ASTM A312/ ASTM A249/ ASTM A269/ EN10216-5/GOST 9940 /GOST 9941...② OD RANGE : 6-1016 MM③ THICKNESS RANGE: 1-65 MM
Seamless Stainless Steel Heat Exchanger Tubing is a component used to transfer heat between two or more fluids without mixing them. XTD is a Leading manufacturer of stainless steel heat exchanger tubes based in Songyang,China. We specialize in producing high-quality stainless steel heat exchanger tubes that meet ASTM 213 international standards. They are used in various industrial applications such as chemical processing, power generation, HVAC, and food processing.
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
253MA Seamless Stainless Steel Tube is a tube which features seamless construction, excellent heat and corrosion resistance, and long-lasting durability. ① STANDARD: ASTM A213/ EN10216-5/ ASTM A249/ ASTM A269/EN10216-5/ GOST 9940 /GOST 9941...② OD RANGE : 6-257MM③ THICKNESS RANGE: 1-35 MM
