Black steel pipe is darker than galvanized pipe; it is flat black while galvanized pipe is silver and gray.And second,galvanized pipes are usually used for water transportation whereas black steel pipe for gas deliver.Other types of coatings Depending on the use of the pipe results for this questionWhat are black steel pipes?What are black steel pipes?What are black steel pipes? Black steel pipes are made of steel that has not been coated with a substrate such as zinc or paint.Since it has a dark color surface that is forms by iron oxide during the manufacturing process,it is called black steel pipe.What are black steel pipes used for?8 Things You Need To Know About Black Steel Pipes results for this questionWhat is the difference between pipe and welded pipe?What is the difference between pipe and welded pipe?They are usually seam welded. Pipe,on the other hand,is always round and rigid.It cannot be shaped easily without the use of a special equipment.Pipes are usually seamless and pressure rated to avoid leakages as they usually carry liquids or gases.4.ToleranceSteel Tubes and Pipes what are the main differences
