Tube Production Objectives through the Application of In-Line Gauge Control

  • Provide Reactive Control of Tube Wall in ERW Tube Production. Give the operator the ability to CHANGE the incoming gauge and correct camber conditions.
  • Permit Consistent Production of HIGH QUALITY Tube Products. The operation that does not provide quality products will be gone!
  • Provide the capability to use Alternative raw materials.
  • Upgrade hot rolled gauge tolerances so it can be substituted for cold rolled, where surface finish is not a requirement. Reduce raw material cost.
  • Upgrade HRS P/O gauge tolerance so it can be substituted for cold rolled where surface concerns are an issue. Reduce raw material cost.
  • Upgrade low carbon steel to the strength requirements of a higher carbon or a medium carbon to that of HSLA. Reduce raw material cost.
  • Reduce Production Cost, Increase Profits. Maximize utilization of the available personnel skills and raw material! Reduce waste. Maintain labor cost while Increasing Production. Increase profits.

What is In-Line Gauge Control ?

  • An operator controllable process to maintain material thickness entering the tube mill. With non-contact thickness measurement at the exit of the tube mill, a closed loop control can automatically adjust entry strip thickness.
  • A self-correcting thickness control that adjusts for both variation in strip thickness and hardness, once set by the operator.
  • An automatic process that can also reduce strip camber problems while correcting thickness variation.

Why Use Gauge Control ?

  • Reduce roll wear and reduce set up time by providing uniform strip thickness with reduced camber variation.
  • Permit purchase of commercial grades in lieu of close thickness tolerance.
  • Permit substitution of material grades.
  • Actively make Tube Walls to +/- 0.0005" of desired wall.
  • The process converts over gauge material to thinner and longer sections. On strip widths common to small tube production, the vast majority of material growth is to length, with normal reductions being 10% or less. The width growth for a reduction of 8% would be on the order of + 0.1 to 0.2%. As strip width increases the growth in width decreases.
