Hi, the above question is pretty much what I want to ask. Thank you.

"This specification covers for several grades of carbon and alloy steel mechanical tubing, either hot-finished or cold-finished. The steel used in the mechanical tubing may be cast in ingots or may be strand cast. When steel of different grades is sequentially strand cast, identification of the resultant transition material is required. The seamless tubing is a tubular product made without a welded seam. It is usually manufactured by hot working steel, and if necessary, by subsequently cold finishing the hot-worked tubular product to produce the desired shape, dimensions and properties. The tubes shall be furnished in the following shapes: round, square, rectangular and special sections. Heat analysis shall be made to determine the percentages of the elements specified. If secondary melting processes are used, the heat analysis shall be obtained from one remelted ingot or the product of one remelted ingot of each primary melt. The tubing shall be coated with a film of oil before shaping to retard rust when specified"

"Tubing" is called out to OD and wall thickness (an even increment value). 6" x 1/4" round tubing will be 6" OD x 5.500" ID.
"Pipe" is called out as nominal pipe size (ID) and "schedule" for wall thickness. 6" Schedule 40 pipe will be 6.625" OD with 0.280" wall, and thus 6.065" ID.
Mechanical tubing is used for all sorts of general fabricating and machining. For instance, a race car frame, such as a NASCAR vehicle, is made from A519 4130 tubing that has been bent and welded together. (Well, they were in the 90's.) Many round & hollow machinery parts which are turned to shape on a lathe are made from 4130 tubing. A seat ring in a ball valve for instance.
