ASTM B111 C12200 Seamless (Smls) Tube, High-Quality Copper Alloy Seamless Tube
ASTM B111 C12200 Seamless (Smls) Tube, High-Quality Copper Alloy Seamless Tube
Brief Introduction
C12200 B111 Seamless (Smls) Tube is a high-performance copper alloy seamless tube, strictly manufactured in accordance with ASTM B111 standard (Standard Specification for Seamless Copper and Copper Alloy Tubes for Condensers and Heat Exchangers). It is mainly made of C12200 copper alloy (commonly known as red copper), which has excellent thermal conductivity, electrical conductivity, ductility and corrosion resistance. As a seamless-structured product, it eliminates the hidden dangers of leakage and structural instability caused by welding seams, ensuring high pressure resistance and long-term stable operation. The product integrates the superior performance of C12200 copper alloy and the structural advantages of seamless tubes, and is widely used in scenarios requiring efficient heat transfer, corrosion resistance and good electrical conductivity, such as condensers, heat exchangers, hydraulic systems and marine equipment.
