Daiwa Thermic Lance is a well-known and widely used variant of the oxygen lance pipe, which is primarily utilized for oxygen blowing systems in Electric Arc Furnace (EAF) operation across steel mills, foundries, and mining facilities worldwide. Despite its widespread adoption in the global steel manufacturing industry and metallurgical operations, many professionals remain unfamiliar with Thermic Lance technical specifications and cutting methods.
To save you significant time, we have compiled all the technical information, applications, and benefits of Daiwa Thermic Lance in the blog below.
What is Daiwa Thermic Lance?
Daiwa Thermic Lance, sometimes called a thermal lance or burning bar, is essentially a specialized steel pipe filled with steel wires that creates an incredibly hot cutting tool. Think of it as a consumable torch that burns itself up while doing the work.
How does Daiwa Thermic Lance Work?
Getting Thermic Lance going is straightforward. You start by igniting it with a conventional acetylene torch – just like lighting a giant matchstick. Once it's lit, pure oxygen is fed through the pipe from an oxygen cylinder and regulator. This oxygen flow is what transforms the lance from a simple steel pipe into a powerhouse cutting tool.
The magic happens through a simple but powerful chemical reaction. When you feed pressurized oxygen into the ignited steel tube, it triggers an iron oxidation process (4Fe + 3O₂ → 2Fe₂O₃ + heat). This exothermic reaction generates an intense flame reaching temperatures up to 3,600°C – that's hot enough to cut through most metals quickly and efficiently.
What makes Thermic Lances special is their thermal cutting method. Unlike other cutting tools, they work completely silently without any vibration, making them perfect for situations where noise is a concern. The steel wires inside the pipe keep the combustion going strong, essentially turning the entire lance into a high-temperature cutting flame.
What is Thermic Lance Used For? Real-World Applications That Matter
Wondering where you'd actually use a Daiwa Thermic Lance in the real world? The applications are more diverse than you might think. From massive industrial operations to specialized cutting tasks, here's where this powerful tool really shines.
Steel Mills & Foundries:
- Opening iron notch and tap holes in blast furnaces, electric furnaces, and cupola furnaces
- Removing stubborn solidified metals and slag buildup from plant decks, working floors, and ladle furnaces
- Cleaning blocked ladle nozzles and tundish nozzles in continuous casting operations

The bottom line? If you need to cut through something thick, tough, or seemingly impossible to penetrate, chances are a Daiwa Thermic Lance can handle it.
What Types of Daiwa Thermic Lance are Available?
Daiwa Thermic Lance Type T - For Standard Industrial Materials
Daiwa Thermic Lance Type T features a mixture of wires and an inner pipe design that creates a straight flame at high speed. This concentrated heat can splash through materials, punch holes, or break up substances quickly and efficiently. Type T works particularly well on common industrial materials like carbon steel, iron, slag, copper, aluminum, and brass. It's your go-to choice for most standard metal cutting and scrap processing jobs.
Daiwa Thermic Lance Type W - For High-Temperature Applications
Type W comes with a full pack of wires that produces a wider flame at an even higher temperature than Type T. Its distinct feature is the ability to dissolve solid materials with high melting points that would challenge other cutting methods. This makes Type W ideal for tackling tough materials like stainless steel, nickel, concrete, refractory materials, and natural stone.
The beauty of the Daiwa Thermic Lance system lies in its simplicity – just acetylene ignition, oxygen flow, steel, and controlled combustion working together to create one of the most effective thermal cutting methods available, with options tailored to your specific material challenges.
What Sizes are Available for Daiwa Thermic Lance?
Here's the thing about Thermic Lances - size isn't just a number, it's everything. The diameter, thickness, and length you choose can make or break your cutting project success. Let's break down how to pick the perfect fit for your needs.
- Large Diameter, Long Lances: These are your heavy-duty workhorses. Perfect when you're tackling major industrial demolition or need to cut through massive steel structures. More power, deeper penetration.
- Smaller Diameter, Short Lances: Precision is the name of the game here. Skillful operators often love these for detailed work where control matters more than raw cutting power.

What Types of Connection for Daiwa Thermic Lance?
Method 1: Plain End Connections - Simple and Straightforward
What are plain end connections? Plain end Thermic L lance pipes come without any threading or coupling attachments. Think of them as the "standalone" option for your piping needs.
When should you use plain ends? This connection type works perfectly when you need just one piece to complete your job. Many customers love this option because it's cost-effective and eliminates unnecessary complexity. If your project doesn't require multiple pipe sections, plain ends are your best bet.
Key benefits:
- No additional fittings required
- Lower overall cost
- Quick installation for single-piece applications
- Minimal maintenance needs
Method 2: Thread & Socket Connections - Maximum Efficiency
How do thread & socket connections work? This popular connection method allows you to join multiple Thermic Lance together seamlessly. The threaded end of one pipe screws directly into the socket of another, creating a secure, leak-proof connection.
Why do customers prefer this method? Here's the game-changer: you won't waste half of your used Thermic Lance like you might with other connection methods. This means better material utilization and significant cost savings over time.
Perfect for:
- Multi-section installations
- Projects requiring pipe extensions
- Applications where you need to maximize pipe usage
- Situations where you want easy disassembly for maintenance
Method 3: Quick Coupling - Fast and Foolproof
What makes quick coupling so popular? Quick coupling is the speed demon of connection methods. Your operator simply needs to hit Thermic Lance and coupling together against the wall or floor a few times, and you're connected. It's that simple.
Why choose quick coupling?
- Lightning-fast installation
- Minimal training required for operators
- Reduced labor time and costs
- Virtually foolproof connection process
Most popular specification: The 1/4" (OD 13.8mm) x Length Type T is the go-to choice for most quick coupling applications. This size offers the perfect balance of strength and versatility for typical industrial applications.
Which Connection Method Should You Choose?
Your choice depends on your specific project requirements:
- Choose plain ends if you need a single pipe section and want the most economical option
