Size Range
Tubular products seamlessmechanical tubing is furnished in both cold-drawn and hot finished formin a wide range of sizes, from 1.375″ to 7.750″ OD and from 0.188″ to1.625″ wall thickness.
Minimum Quantities
Hot-finished carbon and alloy—10,000 pounds, or 4,536 kilograms minimum.
Cold-drawncarbon and alloy—5,000 pounds minimum or 125 feet minimum, 2,268kilograms 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 specialseamless 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 forthe end use.
The configurations are formed from round tube by colddrawing. The tube is drawn over a shaped mandrel or through a shapeddie, or both. Improved tolerances, finishes and mechanical propertiesresult.
