ON-SITE FLANGE FACING

It orbits. It trues.

ORBITRUEPortable flange facing machines

ORBITRUE is the Maucotools family of flange facing machines: they clamp in the bore, orbit around the axis and re-machine the sealing face directly on the plant, without dismantling the line.

Six sizes cover flanges from 1" to 80". The model number is the maximum facing diameter in inches: choose the size by diameter, then the drive.

HOW IT WORKS

IT ORBITS AROUND THE FLANGE AXIS

The principle is the same across the family, from the 19" manual to the 80" motorised machine: a fixed axis in the bore, a rotating arm, a tool feeding radially.

01

It clamps in the bore

Mounting is internal (ID mount): the machine centres and locks in the flange bore, which becomes the axis of rotation. No external reference to build.

02

The arm orbits

The arm rotates around the axis, by hand on the ORBITRUE 19 Manual and motor-driven on the motorised sizes, carrying the tool across the whole face.

03

The tool leaves a spiral

At every revolution the tool feeds radially: the result is the continuous spiral (“phonographic”) finish required on gasketed sealing faces.

MANUAL OR MOTORISED

TWO WAYS OF WORKING

ORBITRUE 19 Manual

Manual: it goes anywhere

ORBITRUE 19 Manual is hand-operated: no power supply, a 331 × 191 mm footprint, transport in a carrying case. It is the machine for small and medium flanges and for quick maintenance jobs.

  • Facing Ø 25–482 mm (1"–19")
  • Bore clamping Ø 25–152 mm
  • No motor, no cables, no hoses

Motorised: productivity and large diameters

Five motorised sizes cover flanges from 1" to 80". Rotation and feed are constant, so the finish is repeatable from one revolution to the next and from one flange to the next.

  • Facing up to Ø 2032 mm (80")
  • Four drives for every size
  • Sizes 40 and 80 are on the Switch System platform

DRIVES

Electric, pneumatic, hydraulic or CNC

Every motorised size is available with four drives: the mechanics do not change, you choose the energy available on site.

Electric

Electric gearmotor: the simplest choice in the workshop and on site, wherever mains power is available.

Pneumatic

Compressed-air motor, for plants where the available energy is the air line.

Hydraulic

Hydraulic motor with power pack: high torque and continuously adjustable speed.

CNC

Numerically controlled motorised axes, for repeatable cycles and programmed profiles.

SWITCH SYSTEM PLATFORM

THE LARGE SIZES ARE ALSO ANOTHER MACHINE

ORBITRUE 40 · 18–40"ORBITRUE 80 · 40–80"

ORBITRUE 40 and ORBITRUE 80 are built on the Switch System: with the Switch Kit the flange facing machine turns into a large-diameter line boring machine, and back again. Whoever buys the flange facer already owns the core of a second machine.

APPLICATIONS

WHERE IT IS USED

Oil & gas and petrochemical

Line flanges, valves and nozzles: restoring the sealing face during shutdowns and maintenance, without taking the part to the workshop.

Power and process

Heat exchangers, pressure vessels, pumps and turbines: large-diameter flanges machined in place.

Marine and offshore

On-board piping and equipment, where dismantling and transport cost more than the job itself.

Maintenance and service

Mobile workshops and maintenance contractors: a scored or corroded face is recovered on site.

FREQUENTLY ASKED QUESTIONS

BEFORE YOU CHOOSE

It re-machines the sealing face of a flange damaged by corrosion, scoring or distortion, directly on the plant. The machine clamps in the flange bore, orbits around its axis and restores flatness and surface finish without dismantling the line.
