    This process greatly improved the quantity and quality of steel production. It added three hours firing time and required large quantities of coke. In making crucible steel, the blister steel bars were broken into pieces and melted in small crucibles, each containing 20 kg or so. This produced higher quality metal, but increased the cost.

    The company's inspection procedures set a standard for the production of steel tube. Both seamless and welded manufacturing processes were perfected by the company and impacted other manufacturers in their products. National Tube manufactured over fifty different types of tube during the time. [2] As Pittsburgh's steel industry declined during ...

    The cold drawing process for steel bars and wire is as follows: Tube lubrication: The surface of the bar or tube is coated with a drawing lubricant such as phosphate or oil to aid cold drawing. Push Pointing: Several inches of the lead ends of the bar or tube are reduced in size by swaging or extruding so that it can pass freely through the ...

    en.wikipedia.org/wiki/Tube_drawing

    Tube drawing is a process to size a tube by shrinking a large diameter tube into a smaller one, by drawing the tube through a die. This process produces high-quality tubing with precise dimensions, good surface finish, and the added strength of cold working. [1] For this reason this process is established for many materials, mainly metalworking ...

    en.wikipedia.org/wiki/Tube_bending

    The process of tube bending involves using mechanical force to push stock material pipe or tubing against a die, forcing the pipe or tube to conform to the shape of the die. Often, stock tubing is held firmly in place while the end is rotated and rolled around the die.

    During the manufacturing process the mother tube goes through a series of shaping stands which form the round HSS (mother tube) into the final square or rectangular shape. Most American manufacturers adhere to the ASTM A500 or newly adopted ASTM A1085 standards, while Canadian manufacturers follow both ASTM A500 and CSA G40.21.
