Super Heating Nozzles - 1H to 5H  Oxy / Propane

Oxy / Propane Super heating nozzles sizes #1H to #5H are used throughout industry for a wide variety of heating applications, very frequently being used in "pre & post" heating for welding applications.

Typical uses include to heat large plates for forming operations, expanding items for fitment over shafts and other similar applications.  Heating bent parts so they may be repositioned back to the way they should be when moving without heating would cause tearing.

Noz-Alls super heating nozzles are generally used with an Excalibur Type 5 shank, propane heavy duty mixer and long stainless steel neck (300mm, 500mm, 700m or 900mm), alternatively using a "super heating adaptor" which is fitted directly into extended length cutting torch, which provides higher heat output.
These nozzles are all produced to our engineering drawings to ensure correct gas flow and the proper heat output.
All our super heating nozzles are castellated for safety and may be touched down without fear of flame retraction / equipment damage.
Correct setting of these nozzles is vital to ensure the fuel is burnt correctly.  Avoid a soft flame, if you have too much heat change to a smaller size.

These nozzles have sometimes been referred to me as "Pepper Pots" however it is not so appropriate for these 2290 H Super Heating nozzles when compared to other heating nozzle styles.

Heating nozzle size - Identification
2290 -1H length 78mm - Dia. 19mm slots 10 small
2290 -2H length 78mm - Dia. 19mm slots 12 large
2290 -3H length 78mm - Dia. 25mm slots 8 plus 14 
2290 -4H length 78mm - Dia. 35mm slots 14 plus 22 
2290 -5H length 78mm - Dia. 44.7mm slots 20 plus 30 

Operating Pressures in bar gauge
2290H - 1H  propane 0,15 - 0,5     oxygen  0,7 - 2,1
2290H - 2H  propane 0,15 - 0,5     oxygen  0,7 - 2,1
2290H - 3H  propane 0,3 - 1,1      oxygen  1,8 - 5,0
2290H - 4H  propane 0,35 - 1,3     oxygen  2,5 - 5,7
2290H - 5H  propane 0,85 - 2,1     oxygen  3,5 - 8,7

These are pressures required at the nozzle / inlet connections to the blowpipe, flow restrictions caused by hose lengths, poor quality HCV, incorrectly sized equipment will all cause a pressure drop which will have to be compensated for.

Generally as a minimum only use 10mm bore hoses with a short length, when operating the #4H and #5H use a high flow oxygen flashback arrestor.
