What is a manual pipe gas cutting machine?

A portable carriage that clamps onto a pipe with a chain and carries an oxy-fuel torch around it as you turn a hand wheel. It gives a cleaner, more even circular cut and bevel than a free-hand torch. The CRUXWELD TUBOCUT-HG is this type of machine.

Does the TUBOCUT-HG need electricity?

No. The drive is a manual hand wheel with a worm gear, and cutting is oxy-fuel, so it works on sites with no power supply.

What pipe sizes can it cut?

Pipes from Ø100 mm upward. The 75-link chain supplied covers pipes up to about Ø600 mm; add chain links for larger diameters. Links needed = pipe OD in cm + 12.

What wall thickness can it cut?

5 to 50 mm, using G02 nozzles No. 1 (5–15 mm), No. 2 (15–30 mm) and No. 3 (30–50 mm).

Can it cut a bevel for welding?

Yes. Set the torch from 0 to 45° on the dial at the torch clamp for a square cut or a weld-ready bevel. The angle can also be adjusted during cutting.

Which gases does it use?

Oxygen with acetylene or propane. Oxygen pressure is 0.30–0.50 MPa depending on the nozzle.

What comes with the machine?

The machine body, cutting torch, G02 nozzles No. 1–3, a 75-link chain, two wheels, six M5 screws, a tool box and an inspection certificate. Gas cylinders, regulators and hoses are not included.

000° · START OF THE CUT

Free-hand pipe cuts wander. This doesn’t.

Cutting a round pipe with a hand torch means walking the flame around a curve by eye. The edge wanders, the bevel changes as your wrist tires, and the joint then needs grinding before it can be fitted up.

The TUBOCUT-HG manual pipe gas cutting machine takes the torch out of your hand. A chain holds the machine tight on the pipe, four wheels ride the surface, and a worm-gear hand wheel moves it around at a steady pace while the torch holds its height and angle. You get a square cut or a weld-ready bevel, on the shop floor or out on the line, where there is no power.

090° · MOUNT AND CUT

Five steps from bare pipe to a finished ring

1Place it on the pipeSit the machine on the pipe at the cut line, within the torch’s cross-travel range.
2Tension the chainWrap the chain round the pipe, press the spring and hook it so the machine is held tight.
3Light and set the flameLight the nozzle and regulate the preheat flame for the wall thickness.
4Set the torchMove the torch to position and height, and set the bevel angle on the dial.
5Cut and turnOpen the cutting oxygen and turn the hand wheel at the same time, at an even pace, all the way round.

Steady hand, clean edge: turn the hand wheel at an even pace while the cutting oxygen is open, all the way round.

135° · CHAIN LENGTH

How many chain links for your pipe?

The chain is made of detachable square links, so you set its length to the pipe. The rule is simple: links needed = pipe OD in cm + 12. Tap your pipe size:

4″6″8″10″12″16″18″20″

24 linksfor a 4″ pipe, Ø114.3 mm OD

11.4 cm + 12 = 23.4 → 24 links

24 of the 75 links supplied

29 linksfor a 6″ pipe, Ø168.3 mm OD

16.8 cm + 12 = 28.8 → 29 links

29 of the 75 links supplied

34 linksfor a 8″ pipe, Ø219.1 mm OD

21.9 cm + 12 = 33.9 → 34 links

34 of the 75 links supplied

40 linksfor a 10″ pipe, Ø273 mm OD

27.3 cm + 12 = 39.3 → 40 links

40 of the 75 links supplied

45 linksfor a 12″ pipe, Ø323.9 mm OD

32.4 cm + 12 = 44.4 → 45 links

53 linksfor a 16″ pipe, Ø406.4 mm OD

40.6 cm + 12 = 52.6 → 53 links

58 linksfor a 18″ pipe, Ø457 mm OD

45.7 cm + 12 = 57.7 → 58 links

63 linksfor a 20″ pipe, Ø508 mm OD

50.8 cm + 12 = 62.8 → 63 links

75 links come with the machine: enough for pipes up to about Ø600 mm
Larger pipes: add chain links to suit the diameter
Minimum pipe size: Ø100 mm

315° · CARE AND SAFE CUTTING

Keep it running smooth, keep the crew safe

After every job

Clear slag and dirt from the wheels and chain
Put a light film of oil on the sliding parts
Store it dry, in its tool box
Keep the pipe support surface flat and leave room for the machine to travel round

Every time you cut

Fit flashback arrestors and check valves on both lines
Leak-test joints with soapy water, never a flame
Do not cut pipe with wet paint on it
Wear goggles and protective clothing; keep flammables clear
