    Size Range

    Tubular products seamless mechanical tubing is furnished in both cold-drawn and hot finished form in a wide range of sizes, from 1.375″ to 7.750″ OD and from 0.188″ to 1.625″ wall thickness.

    Minimum Quantities

    Hot-finished carbon and alloy—10,000 pounds, or 4,536 kilograms minimum.
    Cold-drawn carbon and alloy—5,000 pounds minimum or 125 feet minimum, 2,268 kilograms minimum or 38.1 meters minimum, whichever is greater.
    Quantity variation—standard ±10% of the ordered weight, or ±25 feet or 7.61 meters, whichever is greater.

    Special Configurations

    Tubular Products special seamless tubing configurations start with the highest quality steels. Grade, chemical analysis and surface condition are carefully considered, and production processes are tailored to achieve the best tubing for the end use.
    The configurations are formed from round tube by cold drawing. The tube is drawn over a shaped mandrel or through a shaped die, or both. Improved tolerances, finishes and mechanical properties result.
