Copper Pipe is used in plumbing for over half a century now. This is because copper has good resistance against chemical and mechanical corrosion. The corrosion resistance is superior to most steel materials and copper can last longer. The downside of copper is that it cannot take acidic corrosions. On the other hand, copper reduces the weight and the secondary processing involved in other materials. The copper pipe parts are ductile and are malleable. So the material could be easily formed into different shapes and used as per requirements. The copper pipe has very low embrittlement risk. Meaning, when deformed into different shapes, the metal does not crack or break.
This capacity allows plumbing with copper an easy task. Often times, copper could be used without other types of connectors because of the malleability. There are different grades and standards of copper pipes. Among the four major types, the M and L are mostly used with water lining. Where plumbing has to be so precise or is done in a high end and high cost environment, the copper seamless pipe is preferred because it could bring an aesthetic look and precision to the application. Even in precise applications, the wall thickness is important. The L type has higher wall thickness and is recommended for high pressure plumbing needs. But where the wall thickness can be reduced, the M type is preferred because it is cost efficient. Due the lesser wall thickness, the type M copper pipe price is much lower than the L type.
