ASME SB111 Aluminum Brass C68700 Seamless U Bend Heat Exchanger Tubes
YuHong Group as one of the leading suppliers in China to supply U bend tubes and has many experiences in exporting to 35 countries.
Each U bend tube of our range is rigorously quality checked by our team of professionals on every produce of production to provide customers with defect-free quality products.
These U-shaped bends can be custom designed in various diameters according to customer requirements and drawings.
ASME SB111/SB111M This specification establishes requirements for seamless tube and ferrule stock of copper and various copper alloys up to 31 ⁄ 8 in. (80 mm), inclusive, in diameter, for use in surface condensers, evaporators, and heat exchangers.
C68700 aluminum brass tube is frequently used in industries such as air conditioning units, heat exchanger tube, freezers, the petrochemical sector, power plants, etc. due to its robust and corrosion-resistant.
For usage in marine and terrestrial power stations with significant cooling water velocity, pipes made of this alloy are advised. In “Seawater desalting plants,” C68700 aluminum brass pipes are frequently utilized,It has strong corrosion resistance .
