ASTM A249 ống thép không gỉ austenit hàn cho dịch vụ nồi hơi trao đổi nhiệt
ASTM A249 / A249M is a standard specification issued by ASTM International for welded austenitic stainless steel tubes used in boilers, superheaters, heat exchangers, condensers, and hydraulic systems. These tubes are manufactured using GTAW or ERW processes and are supplied in the solution annealed condition to ensure corrosion resistance and high-temperature strength. This product covers common grades such as TP304, TP304L, and TP304H, making it particularly suitable for
ASTM A213 ống trao đổi nhiệt thép không gỉ Kháng ăn mòn ống U Bend
U-bend stainless steel heat exchanger tubes are seamless or welded tubes precision-formed into a U-shape, designed specifically for shell and tube heat exchangers. This U-configuration allows the tube bundle to expand and contract freely under thermal stress while eliminating the need for a second tube sheet, making the entire heat exchanger more compact, cost-effective, and easier to maintain. Manufactured from high-quality austenitic stainless steel grades such as 304, 304L
ống trao đổi nhiệt thép không gỉ liền mạch hàn chống ăn mòn
Stainless heat exchanger tubes are high-performance seamless or welded tubes designed for shell-and-tube heat exchangers, condensers, evaporators, and boilers. Manufactured from high-quality austenitic stainless steel, they offer excellent corrosion resistance, high-temperature strength, and efficient heat transfer. Key Advantages: Excellent resistance to pitting, crevice corrosion, and SCC Maintains mechanical properties at elevated temperatures Smooth inner/outer surface
Ống hàn thép không gỉ TIG ASTM A269 được đánh bóng bằng điện
The TIG Welded Stainless Steel Pipe is manufactured using Tungsten Inert Gas (GTAW) welding technology, which produces a high-quality, consistent longitudinal weld seam with excellent penetration and minimal heat input. This process results in a smooth, clean weld bead with no spatter or oxidation, making it ideal for applications requiring superior weld integrity and corrosion resistance. TIG welded pipes are widely used in sanitary, pharmaceutical, food processing, and high
