DIN CuZn15 Common Brass Seamless Tubes Good Material For Hot And Cold Water System
1. Description
DIN CuZn15 brass tube is sturdy. It is fire-resistant and heat-resistant. It can keep shape and strength unchanged at high temperature.
DIN CuZn15brass tube combines the advantages of metallic and non-metallic tubes. It is the best connecting pipe in brass pipe of hot and cold water system.
Therefore, DIN CuZn15 brass seamless pipe is usually used in hot water pipe, heating pipe and refrigeration pipe. As an installation pipe, it has the advantages of hard texture, corrosion resistance, high temperature and high pressure resistance, so it can be used in different environments.
