Rolled Tube Joints Leaking After Hydrotest: Causes and Fixes
Leaks at rolled tube-to-tubesheet joints usually come down to under- or over-rolling, tube hole condition or the wrong expander. Find the leaking joints, re-roll them, and retube any that are damaged.How to Set Tube Rolling Torque for Different Tube Materials and Sizes
There is no single torque value for tube rolling. Torque is set by trial rolling against the wall reduction your design requires, for the actual tube material, size, wall and tubesheet.Rolling Titanium Condenser Tubes: What to Watch For
Thin-wall titanium tubes are easy to over-roll and spring back more than copper. Consistent torque, the right rolled length, clean tube holes and full rolling records are what matter.Rolling Thick-Wall and Large-Diameter Steel Tubes
Large, thick-wall carbon and alloy steel tubes need more torque than standard tube rollers deliver. Use a large-tube electric roller or a hydraulic tube roller.Rolling at Intermediate Tubesheets, Double Tubesheets and Thick Tubesheets
Rolling at an intermediate tubesheet or support plate, or through a thick tubesheet, needs long-reach expanders.Tube Rolling in Hazardous Areas: Choosing an Explosion-Proof Tube Roller
Refinery and petrochemical turnarounds often involve flammable media, so electric tools are a spark risk. Use air-driven or hydraulic tube rollers.Traceable Tube Rolling Records for Inspectors and Owners
Nuclear, large power and export projects often require rolling data for every joint. Servo and electric tube rollers with built-in recording export it directly.
