Mathey Dearman / SFE Group Pipe Cutting and Alignment Equipment
Pipe flame cutting machines, beveling systems and alignment clamps by Mathey Dearman / SFE Group: equipment selection, accessories and component support.
Saddle Machine Motorized and Manual Pipe Cutting Systems
Mathey Dearman Saddle Machine pipe cutting equipment provides high accuracy flame cutting and beveling on pipes from 1.5 to 48 inches (38 to 1,219 mm). The split lightweight aluminum alloy framework mounts directly onto operational pipelines without dismantling pipe joints.
- Split lightweight aluminum alloy framework for swift mounting on operational pipelines
- Broad diameter coverage from 1.5 to 48 inches delivering smooth edge bevels
- Electric motorized drive or manual hand crank rotation for torch positioning
- Adjustable torch holder supporting preparation bevel angles from 0 to 45 deg
Portable Chain Pipe Cutters E-Z Pipecut Manual and Auto
The E-Z Pipecut chain-driven pipe cutting machine range delivers mechanized flame cutting on pipes from 4.5 to 24 inches (114 to 600 mm). The continuous guide link chain guides the travel carriage smoothly around the pipe perimeter in challenging shop and field setups.
- Compact drive mechanism with roller guide chain wrapping around steel pipes
- Smooth cutting torch travel for perpendicular square cuts and prepared bevel edges
- Choice between manual mechanical hand crank and motorized automatic electric drive
- Magnetic wheel models providing firm hold on heavy structural industrial steel pipes
Band Crawler Flame Cutting Machines for Large Diameter Pipes
Mathey Dearman Band Crawler pipe cutting systems perform thermal flame cutting and edge beveling on large pipelines from 10 to 60 inches (254 to 1,524 mm). Precision steel guide bands maintain a stable circular path for the mobile crawler carriage in field trench work.
- Calibrated stainless guide bands adapted to exact outer pipeline dimensions
- Self-propelled crawler carriage equipped with electric or manual drive unit
- Low radial clearance profile enabling cutting operations in narrow trenches
- High accuracy edge preparation on large diameter oil and gas transmission lines
Sturdi and Double Jackscrew Chain Alignment and Reforming Clamps
Mathey Dearman Sturdi Clamp and Double Jackscrew pipe chain clamps perform precision alignment and reform pipe out-of-roundness from 1 to 72 inches (33 to 1,829 mm). Jackscrews apply steady mechanical force to balance wall hi-lo alignment prior to welding.
- High-tensile alloy roller chain with dependable screw tensioning mechanisms
- Double jackscrews delivering mechanical force to reform pipe out-of-roundness
- Universal fit-up capability for pipe-to-pipe, pipe-to-fitting and flange joints
- Stainless steel contact points preventing carbon contamination on alloy piping
Rim Clamps and Hydraulic Cage Clamps for Pipe Reforming
Mathey Dearman Rim Clamps and heavy-duty Cage Clamps reform heavy-wall pipeline ends and align joints across diameters from 4 to 60 inches (114 to 1,524 mm). The open arch layout provides unrestricted welder access around the root weld seam perimeter.
- Rigid welded ring framework built for tough overland pipeline installations
- Lever ratchet or high-force hydraulic mechanisms for rapid clamp tightening
- Clear radial gap allowing continuous root pass deposition without obstruction
- Hinged swing-open segments enabling rapid repositioning along the pipeline joints
Pipe Rigging Equipment, Beam Rollers and Launchers
Mathey Dearman pipe rigging tools include Beam Clamp Rollers, Pipe Launchers and heavy-duty Slings & Cradles designed for pipe diameters from 2 to 60 inches (50.8 to 1,524 mm). They safeguard external factory coatings during pipeline pulling and positioning.
- Polyurethane and elastomer roll surfaces protecting external factory pipe coatings
- Rapid clamp-on screw mounting attaching securely to structural steel flange beams
- Smooth longitudinal feeding for rack piping, river crossings and push-pull ops
- Heavy-duty sling cradles ensuring safe overhead lifting of pipeline strings
Mathey Dearman heritage and S.F.E. Group integration
Mathey Dearman traces its roots to 1936 in Tulsa, Oklahoma, when founder Chester A. Mathey developed the first portable saddle machine for pipeline cutting.
In 1974, Tim Dearman invented innovative pipe alignment and reforming clamping tools, culminating in the 1986 merger creating Mathey Dearman Inc.
In 2019, Mathey Dearman joined forces with B&B Pipe and TAG Pipe Equipment under Specialized Fabrication Equipment (S.F.E.) Group, expanding global engineering capabilities.
Saddle Machine pipe cutting and preparation engineering
Mathey Dearman Saddle Machine systems operate in manual and motorized configurations for pipe diameters from 1.5 to 48 inches (38 to 1,219 mm). The split aluminum alloy framework mounts over pipeline sections without dismantling connecting joints.
Precision gear drives rotate the cutting torch around the pipe perimeter, while a graduated torch arm establishes preparation bevel angles from 0 to 45 degrees for reliable root weld application.
E-Z Pipecut chain cutters and Band Crawler systems
For mobile field fabrication, E-Z Pipecut chain machines provide smooth mechanized flame cutting for pipes from 4.5 to 24 inches (114 to 600 mm). The continuous link chain wraps around the pipe to steer the travel unit.
For large transmission pipelines from 10 to 60 inches (254 to 1,524 mm), self-propelled Band Crawler systems follow calibrated flexible steel bands, achieving square cuts and consistent bevel profiles in narrow trench jobs.
Sturdi and Double Jackscrew precision chain alignment
Proper joint fit-up requires accurate alignment and out-of-roundness correction. Mathey Dearman Sturdi Clamp and Double Jackscrew chain tools cover pipe sizes from 1 to 72 inches (33 to 1,829 mm). High-strength jackscrews apply balanced force to reform deformed pipe walls.
The open layout grants full welder access to deposit continuous root weld beads, while stainless steel contact pads prevent carbon contamination on high-alloy piping.
Rim Clamps and heavy-duty Cage Clamps for pipeline fit-up
Cross-country energy pipelines require robust joint reforming tools. Mathey Dearman Rim Clamps and Cage Clamps support pipe diameters from 4 to 60 inches (114 to 1,524 mm). Equipped with heavy lever ratchets or compact hydraulic cylinders, these welded steel frameworks deliver high clamping force.
They secure heavy pipe ends, fittings and flanges rigidly in place, reducing assembly time and avoiding internal joint stresses.
