4 Small-but-Big-Impact Accessories for Oxygen Lance Pipe

Have you ever wondered why, even after purchasing a high-quality oxygen lance pipe, you still face difficulties using it for blowing air, heating, and cutting metal in foundries? What is needed to bring about real improvements to enhance the overall performance of this consumable product?

4 Accessories of Oxygen Lance Pipes

In fact, an oxygen lance pipe does not work alone. It must be used with other mechanical accessories to function properly. If the accessories are not compatible, damaged, or worn out, the oxygen lance pipe cannot fully perform its oxygen-blowing function.

This article introduces the functions and characteristics of holder, socket, coupling, and press die set - 4 essential accessories that are indispensable for an oxygen lance pipe. Understanding their features will help you use the oxygen lance pipe more effectively and safely.

Lance Holder

Function

  • Lance holder is a device used to connect an oxygen lance pipe with an oxygen supply hose. One end of lance holder will be attached to the oxygen lance pipe, while the other end is connected to the oxygen hose. Each lance holder has a valve for opening and closing the oxygen.
  • Lance holder helps stabilize the oxygen lance pipe and deliver the appropriate oxygen levels during use, promoting safety and precision in operations.

    Especially the lance holder's design also features an anti-backfire valve that allows oxygen to flow in only one direction, greatly enhancing operator safety.

Daiwa Lance Holder

Characteristics

The lance holder's design focuses on facilitating the key functions of oxygen lance pipes, which are gas blowing and cutting, as detailed below.

  • Lance holder helps to adjust the position and angle of oxygen lance pipes flexibly.
  • Lance holder is made from sturdy and heat-resistant materials for enhanced safety.
  • Lance holder is equipped with an anti-backfire valve that can protect operators from backfire.
  • Lance holder helps to ensure a secure connection to the lance pipe and prevent oxygen leakage during use.
  • Other features of the lance holder include the lightweight handle, easy opening-closing, and smooth on-off operation.

Based on the diameter of the pipe, there will be different sizes of lance holders. Therefore, it's important to carefully check the diameter of both the oxygen lance pipe and the oxygen supply hose before buying a lance holder.

New call-to-action

Steel Socket 

Function

  • Socket is a fitting with inner threads used to join two threaded oxygen lance pipes together to get a desired length for safety operation.
  • A key feature to note when using socket is that the oxygen lance pipe must have at least one threaded end.
  • Connecting oxygen lance pipes will become easier with a socket because we just need to screw the socket onto the threaded end of the oxygen lance pipe to complete the connection.

Characteristics

  • Socket from Daiwa Lance complies with international standards such as BS, ASTM, JIS, etc.
  • Socket from Daiwa Lance is suitable for all sizes of threaded oxygen lance pipes.
  • Socket size can be customized subject to the specific thread standards requested by customers.

Category 

  • There are various sizes of sockets that are available to suit different diameters of oxygen lance pipes.
  • There are two main types of sockets: aluminum sockets and steel sockets. It is recommended to use an aluminum socket with aluminum pipes and a steel socket with steel pipes.

Steel Coupling

Function

  • Coupling is a threadless type of connection particularly suitable for threadless pipes.
  • Coupling can be used with or without a press coupling machine to connect two lance pipes. 
  • The most important function of the coupling is to create an airtight seal, minimizing gas leaks and ensuring high safety for operators when blowing oxygen or other gases into the furnace.

    Daiwa Coupling

Characteristics

  • Couplings come in various sizes tailored to the needs, purposes, and diameters of oxygen lance pipes used in the furnace.
  • The elasticity of couplings is sufficient to meet both technical requirements and practical use.
  • The steel grade of the coupling has elasticity compatible with the steel grade of oxygen lance pipes, that's why the elongation of coupling is usually required over 40%.

Category

To make the process of connecting oxygen lance pipes more efficient, we classify couplings into 3 main types:

Standard Coupling 

Standard coupling is a type of coupling that requires the use of a press coupling machine.

Quick Coupling

  • Quick Coupling is a type of coupling that can be connected by hand without the need for a press machine.
  • Quick Coupling is suitable for threadless oxygen lance pipes with an outer diameter smaller than 21.4mm.

Press Quick Coupling 

  • Press Quick Coupling is a type of coupling that can be connected by hand without the need for a press machine.

  • Unlike Quick Coupling, Press Quick Coupling has one end pre-pressed, offering time-saving benefits and ease of use in tight spaces.

  • Press Quick Coupling is suitable for threadless pipes.

Press Die Set 

Function 

  • Press die set is specifically designed for use with a press coupling machine to press couplings into oxygen lance pipes in order to connect pipes to pipes.
  • Each press die set is tailored to fit a specific oxygen lance pipe size.
  • Press die set helps to ensure an airtight connection when using a press coupling machine.

Press Die Set

Characteristics

  • Press die set is made of durable materials.
  • Press die set provides excellent resistance to wear and tear.
  • Press die set ensures long-lasting use and reliability.
  • Press die set is available in various sizes, compatible with different needs for a wide range of applications.
  • Press die set is easy to assemble and replace for seamless operation.

Category

The inner diameter (ID) of the press die set is based on the outer diameter (OD) of the press coupling. Each press die set consists of two identical parts that come as a pair.

Conclusion

Above are details on all the essential accessories for effective and safe use of oxygen lance pipes. Understanding each accessory’s functions and characteristics will help us make the right choices, improving performance and safety.
