APPLICATIONS WE SUPPORT

Pipe & Tube Beveling and Weld Prep

Portable beveling tools for on-site machining of pipe and tube, including high-alloy and difficult materials.

Typical jobs:

  • End prepping high alloy pipe including super duplex

  • Precision weld joint preparation

  • J-bevel, face, and bore for automatic welding

  • Compound bevels on heavy-wall pipe

  • Tracking out-of-round pipe I.D. to keep weld preps consistent

  • Pipe weld preparation up to 36 in outside diameter

Related capabilities:

  • Beveling pipe ends at 37.5°, 30°, and other common angles

  • J-prep for orbital welding

  • Step bevels for composite and clad pipe

Pipe & Tube Cutting

Cold cutting and on-site machining where heat-affected zones and distortion are not acceptable.

Typical jobs:

  • Pipe cutting up to 60 in O.D.

  • Concrete-lined pipe cutting and end prepping

  • Storage tank dismantling with precision cutting

  • Track-mounted saw cutting for straight, repeatable cuts on pipe and panels

These applications often pair cutting with beveling, especially on larger diameter or lined pipe.

Boiler Tube Maintenance & Repair

Portable boiler tube end prepping and cutting saws for precision on-site machining of tube and pipe during outages and repairs.

Tube end prep and weld joint creation:

  • Beveling pipe and tube ends (37.5°, 30°, and other procedure-driven angles)

  • Flat facing for accurate fit-up

  • I.D. boring to match tube wall thickness

  • Bevel, face, and bore simultaneously to reduce cycle time

Tube and weld removal:

  • Boiler tube membrane removal between waterwall tubes

  • Weld overlay removal from tube O.D.

  • Peel-back of clad boiler tubes

  • Tube seal weld removal and tube stub removal

  • Tube sheet weld removal and tube stub boring

  • Rifled tube I.D. bores and header tube I.D. bores

Panel, pendent, and access work:

  • High-speed hand-held beveling for local repairs

  • High-speed track-mounted beveling along tube banks

  • Boiler tube panel cutting with track-mounted saws

  • Warped waterwall flex track for curved surfaces

  • Membrane slotting between boiler tubes

  • Pendent tube cutting with track-mounted saws

These applications are core to waterwall panel replacement, single-tube “Dutchman” repairs, and broader boiler outages.

Tube Expansion, Rolling, and Alignment

Mechanical sealing and alignment of tubes in boilers, heat exchangers, condensers, and fin-fan units.

Key applications:

  • Boiler tube expanders for tube-to-sheet joints

  • Rolling motors for torque-controlled tube expansion

  • Tube alignment and weld alignment clamps for waterwall and header work

  • Tube stub boring and alignment in headers and tube sheets

Benefits:

  • Controlled expansion to avoid over or under rolling

  • Consistent mechanical seals across tube bundles

  • Faster alignment and fit-up during outages

Finned Tube, Fin-Fan, and Specialty Applications

Applications where fins, cladding, or special geometry must be removed or worked around.

Typical jobs:

  • Fin-fan tube facing

  • Tube fin removal to expose bare tube for welding
