Refinery and Petrochemical Heat Exchanger Maintenance
Rolling in hazardous areas, thick-wall tubes and flared joints, plus tube end leak testing and pipe beveling: explosion-proof air and hydraulic tube rollers and large-tube rollers.
Typical jobs
- Turnarounds in areas with flammable or explosive media, where tools must be spark-free
- Rolling thick-wall carbon steel and alloy tubes at high torque
- Waste heat boilers and steam generators that need flared joints
- Weld preparation and in-line cutting of pipe
Recommended tools
- HD series hydraulic tube rollers: explosion-proof versions available, 64–1030 N·m
- 850 series air-driven tube rollers: spark-free, stop automatically at the set torque
- DZ-C electric tube rollers for large thick-wall tubes, Φ45–Φ159 mm
- F series flaring expanders: roll and flare in one pass
- GPN / GPK ID-mounted beveling machines and OE OD-mounted cutting and beveling machines
What we need to know
- Tube material, OD, wall thickness and tubesheet thickness
- Hazardous-area rating; air or power supply on site
- Number of tubes and schedule
