A fitting is used in pipe systems to connect straight pipe or tubing sections, to adapt to different sizes or shapes, and for other purposes, such as regulating or measuring fluid flow.
Pipe fitting is the occupation of installing or repairing piping or tubing systems that convey liquid, gas, and occasionally solid materials. This work involves selecting and preparing pipe or tubing, joining it together by various means, and the location and repair of leaks.
Black steel pipe and galvanized pipe are made of steel, but galvanized pipe has a zinc coating while black pipe does not and therefore, galvanized pipe is more expensive and more durable. For transportation, black steel pipe tend to erode more easily than galvanized pipe and on account of this, it is more suitable for transporting gas and galvanized pipe is fit for carrying water instead of gas.
There are certain standard codes that need to be followed while designing or manufacturing any piping system.
