Butterfly cutting insert, shaft17mm, max.100mm,block nozzle3-20mm - Riegler 149652

Butterfly cutting insert, shaft diameter 17 mm, cutting range max. 100 mm, with block nozzle 3 - 20 mm The advantages of block nozzles over ring nozzles are that the flame cone is longer, the distance between the nozzle mouth and the workpiece is greater, so there is less risk of clogging, higher cutting speed, lower gas consumption, easy handling when replacing the nozzles.

About Autogenous welding and cutting equipment

Oxy-fuel equipment works with a flame of fuel gas and oxygen and cuts or joins steel without any electrical supply. The group holds 26 items, from the handle through welding and cutting inserts to nozzles and seals, with overall lengths of 162 to 333 mm. Handle and insert are joined at the shaft and secured with the union nut.

What matters when choosing

• The welding or cutting range of the insert follows the material thickness. Only then does it become clear which insert belongs on the handle.
• Size 1 to 8 identifies the nozzle. It has to match the capacity of the insert, otherwise flame shape and gas consumption will not be right.
• Shaft Ø: insert and handle must share the same shaft size or the two simply will not fit together.
• Gas connection threads: thread 1 at 21.4x20 male, thread 2 at M20x1.5 female or G 1/4 male, and M10x1.0 male at the nozzles. Oxygen and fuel gas must not be interchanged.
• Gas type together with the oxygen and fuel gas operating pressures is stated per item and has to match the regulators set at the cylinders.

Typical applications

• Flame cutting structural steel during cutting and dismantling work
• Oxy-fuel welding of thin sheet and tube
• Heating and straightening distorted components
• Cutting sections and beams in metalworking and steel construction
• On-site repair work on pipework and structures

The parts are made of brass, brass with copper and brass with PA, while the seals are NBR. Manufacturing takes place in Turkey.
