Difference between black steel pipe and carbon steel pipe

Most black steel pipe has a composition similar to ASTM A-53 pipe. The difference between A-53 and common steel pipe like A-106 are so close that some pipe is actually marked to meet both specifications. Black pipe and A 53 can be seamless or welded seam while A106 is seamless.(pipe) Difference between erw and seamless pipe - Oshwin(steel) The cost difference between seamless and erw pipes. Since seamless pipes have a longer manufacturing process, and the operations here are multiple, the cost of seamless pipes is always higher in comparison to a welded pipe.
