Oxy LPG and Acetylene Gas Cutting Application

Why Choose Adonweld Gas Cutting Nozzles

Adonweld supplies industrial-grade gas cutting nozzles for LPG (Propane) and Acetylene applications, engineered for clean cuts, stable flame control, and safe oxy-fuel cutting across fabrication workshops, shipyards, steel plants, and heavy engineering industries.

LPG & Acetylene Compatible Nozzles

We offer dedicated gas cutting nozzles for LPG (Propane) and Acetylene, designed according to fuel-specific flame characteristics to ensure efficient preheating, smooth kerf edges, and reduced slag formation.

2-Pipe Blowpipe & 3-Pipe Nozzle Mix Types

Available for both 2-pipe blowpipe systems (A / B Type) and safer 3-pipe nozzle mix torches (PNM / ANM), where gas mixing occurs only at the nozzle, minimizing flashback risk.

PNM / ANM & Long Series PNME / ANME

Standard PNM / ANM nozzles are suitable for hand cutting, while PNME / ANME long series nozzles are ideal for machine cutting, track burners, and applications requiring extended reach.

Correct Nozzle Sizing for Plate Thickness

Our gas cutting nozzles are available in multiple sizes to match plate thickness from thin sheets to heavy sections. Proper sizing ensures optimal oxygen flow, accurate cutting speed, and gas efficiency.

One-Piece & Two-Piece Construction Options

Acetylene nozzles are supplied in one-piece copper construction for high heat resistance, while LPG nozzles use two-piece design (brass inner and copper outer) for stable mixing and enhanced safety.

Industrial Performance & Safety Focus

Designed for consistent flame stability, controlled oxygen jet, and reliable operation, Adonweld gas cutting nozzles support safer cutting practices when used with proper regulators, flashback arrestors, and recommended gas pressures.

Gas Cutting Torch Types

• 2-Pipe torches are commonly known as Blowpipe type, where oxygen and fuel gas mix inside the torch body.

• 3-Pipe torches are known as Nozzle Mix type, where gas mixing occurs only at the nozzle, offering higher safety and stable flame control.

LPG / Propane Gas Cutting Nozzle

LPG (Propane) gas cutting nozzles are designed for higher gas volume and stable preheating required in oxy-propane cutting. Proper nozzle selection ensures clean cuts, controlled kerf width and reduced flashback risk.

Torch Compatibility:
• 2-Pipe Blowpipe (A / B Type) – Used with B-Type LPG nozzles
• 3-Pipe Nozzle Mix Torch (PNM / PNME) – Safer design, gas mixing at nozzle only

Acetylene Gas Cutting Nozzle

Acetylene gas cutting nozzles are designed for high flame speed and concentrated heat, making them suitable for fast piercing and precision cutting of carbon steel.

Nozzle Construction & Safety:
• One-Piece Copper Nozzle – Best for acetylene and severe heat exposure
• 3-Pipe Nozzle Mix (ANM / ANME) – Reduced flashback risk
• Divergent Bore – Faster cutting with lower oxygen consumption

FREQUENTLY ASKED QUESTION

Questions Mostly Asked By Our Customer

1. What is the difference between 2-Pipe and 3-Pipe gas cutting torches?

2-Pipe Torch: Commonly known as a Blowpipe type, where oxygen and fuel gas mix inside the torch body.
3-Pipe Torch: Known as a Nozzle Mix type, where oxygen and fuel gas mix only at the nozzle, offering higher safety and better flame stability.

2. What does A-Type and B-Type nozzle mean?

A-Type: Generally used for acetylene in 2-pipe blowpipe systems.
B-Type: Commonly used for LPG / Propane in 2-pipe blowpipe systems.
The type refers to nozzle seating and compatibility with specific blowpipe designs.

3 . What is ANM & PNM nozzle?

ANM stands for Acetylene Nozzle Mix.
It is a 3-pipe nozzle mix design used with acetylene gas, where gas mixing occurs only inside the nozzle, reducing flashback risk and improving cutting safety.

PNM stands for Propane (LPG) Nozzle Mix.
It is a 3-pipe nozzle mix nozzle designed for LPG or propane cutting, requiring higher gas volume and stable preheating compared to acetylene.

4. What is the difference between ANM and PNM nozzles?

ANM: Designed specifically for acetylene gas, usually one-piece copper construction.
PNM: Designed for LPG / propane, typically two-piece construction (brass inner + copper outer).
Both are nozzle mix types but optimized for different fuel gases.

5. What are ANME and PNME nozzles?

ANME: Long-series acetylene nozzle for machine cutting or extended reach.
PNME: Long-series LPG / propane nozzle for track burners and machine cutting.
“E” indicates extended length for mechanized applications.

6. Which nozzle is safer: 2-Pipe or 3-Pipe?

3-Pipe (Nozzle Mix) systems are safer because gas mixing occurs only at the nozzle, not inside the torch body. This significantly reduces the risk of flashback.

7. Can LPG and Acetylene nozzles be used interchangeably?

No. LPG and acetylene have different flame characteristics and gas flow requirements.
Using the wrong nozzle can lead to poor cutting quality and safety hazards.

8. How do I select the correct gas cutting nozzle size?

Nozzle size should be selected based on:

Metal thickness
Fuel gas type (LPG or acetylene)
Cutting method (hand cutting or machine cutting)
Correct sizing ensures clean cuts, proper oxygen flow, and gas efficiency.

9. What happens if the wrong nozzle is used?

Using an incorrect nozzle may cause:

Excessive gas consumption
Poor cut quality
Irregular flame
Increased flashback risk

10. Do gas cutting nozzles require safety accessories?

Yes. Always use:

Proper regulators
Flashback arrestors
Correct gas pressures
This ensures safe and reliable gas cutting operations.
