Fire Sleeve 101: An Introduction of How to Manufacture Fire Sleeve (Step-by-Step)

A fire sleeve is a protective covering used to insulate and protect hydraulic and other hoses from high temperatures, fire, and molten metal splashes. Fire sleeve is typically made from a high-temperature resistant braided fiberglass material.

In this blog, we will provide a step-by-step guide about how to manufacture fire sleeves in our fire sleeve manufacturer for industrial and commercial applications.

Fiberglass Fire Sleeve

A fiberglass fire sleeve is a protective covering made from woven fiberglass fabric. It is designed to provide insulation and fire resistance to various types of hydraulic hoses, cables, and wires. The sleeve is typically installed over these components to protect them from high temperatures, flames, and other potential hazards.

Fiberglass fire sleeves are commonly used in industrial and automotive applications where there is a risk of heat or fire exposure. They can withstand extreme temperatures and provide a barrier that helps prevent the spread of fire and heat transfer to nearby objects or materials.

The woven fiberglass material used in these sleeves is known for its excellent thermal insulation properties. It can resist high temperatures and effectively dissipate heat, thereby reducing the risk of damage to the protected components. Additionally, fiberglass fire sleeves can also provide protection against abrasion, chemicals, and moisture.

These sleeves come in various sizes and configurations to accommodate different types of hoses, cables, or wires. They are typically flexible and easy to install, often featuring a hook-and-loop closure or a zipper for convenient application and removal.

The fiberglass fire sleeve is a protective covering made from woven fiberglass fabric. It is used to safeguard hoses, cables, and wires from heat, flames, and other potential hazards. Its thermal insulation properties make it an effective solution for applications where fire resistance and temperature protection are crucial.

Gather Materials and Equipment

To manufacture fire sleeves, you will need the following materials and equipment:

• High-temperature resistant fiberglass yarn
• Braiding machine
• Heat-resistant silicone or other high-temperature coating material
• Measuring tape or ruler
• Cutting machine (optional)

Step 1: Mixing Silicone Rubber

Mixing silicone rubber material is an essential step in the manufacturing process of fire sleeves. Silicone rubber is a high-temperature resistant material that is ideal for use as a coating on fire sleeves. In this section, we will describe the process of mixing silicone rubber to prepare for manufacturing fire sleeves.

Mixing silicone rubber to prepare for manufacturing fire sleeves is a straightforward process that requires careful attention to detail and the proper materials and equipment.

By following these steps, you can produce a high-quality silicone rubber mixture that is ideal for use as a coating on fire sleeves.

Step 2: Coiling Fiber Yarn

Coiling fiberglass yarn for fire sleeves involves wrapping the yarn around a mandrel or spool to create a uniform, compact roll. This process is used to make fire sleeves that are used to protect hoses, wires, and cables from high temperatures, flame, and fire.

The coiling process helps to ensure that the fire sleeve maintains its shape and integrity under extreme conditions, making it an essential component in many industries such as aerospace, automotive, and marine.

Step 3: Fire Sleeve Coating

Fire sleeve coating is a protective layer applied to the outside of a fire sleeve to improve its performance and extend its lifespan. The coatings are typically made of materials such as silicone, fiberglass or other high-temperature resistant materials.

The purpose of the fire sleeve coating is to provide additional insulation and protection from high temperatures, flames, and other hazardous conditions. It helps to prevent the spread of fire and reduces the risk of damage to the underlying hoses, wires, and cables.

There are different types of fire sleeve coatings available, each designed to meet specific performance requirements. Some coatings provide additional abrasion resistance, while others have improved resistance to chemicals and fuels.

The application process for a fire sleeve coating typically involves cleaning the surface of the fire sleeve, applying the coating evenly, and allowing it to cure or dry. In some cases, the fire sleeve may need to be heated to activate the curing process.

It is important to follow the manufacturer’s instructions when applying a fire sleeve coating, as the improper application can result in reduced performance and decreased lifespan of the fire sleeve. Additionally, proper maintenance and inspection of the fire sleeve and coating are necessary to ensure its continued performance and to identify any potential problems or damage.

Step 4: Fire Sleeve Shaping

After the process of fire sleeve coating process, the finished fire sleeve tube is manufactured successfully.

Shaping the tube of a fire sleeve involves forming the tube into a specific shape or configuration that is suitable for the intended application. The process of shaping the tube can be done using a variety of techniques, including heat-forming, molding, or mechanical shaping.

The following are some common methods for shaping the tube of a fire sleeve:

1. Heat-forming: Heat-forming involves heating the tube to a specific temperature and then applying pressure to form it into the desired shape. This method is typically used for creating shapes that are not possible to achieve with molding or mechanical shaping.
2. Molding: Molding involves using a mold to form the tube into the desired shape. This method is often used for producing fire sleeves with complex shapes or for creating multiple identical parts.
3. Mechanical shaping: Mechanical shaping involves using mechanical equipment such as a press or a hydraulic machine to shape the tube. This method is typically used for producing simple shapes and for shaping large quantities of tubes.

Regardless of the method used, it is important to consider the type of material used in the fire sleeve, as well as its intended application, to determine the appropriate shaping method. The heat resistance and abrasion resistance of the material can also impact the shaping process, as some materials may become brittle or weaken when exposed to high temperatures or abrasion.

Step 5: Fire Sleeve Inspection

Fire sleeve inspection is a critical process that helps to ensure the continued performance and safety of the fire sleeve. Regular inspections can identify potential problems or damage that could compromise the ability of the fire sleeve to protect hoses, wires, and cables from high temperatures, flames, and fire.

The following are some common steps for conducting a fire sleeve inspection:

1. Visual inspection: Begin by visually inspecting the fire sleeve for any signs of damage, such as cuts, tears, or abrasions. Look for any signs of discoloration or charring, which could indicate exposure to high temperatures.
2. Measurement: Check the dimensions of the fire sleeve to ensure that it is the correct size for the intended application. This includes measuring the length, diameter, and wall thickness of the tube.
3. Functionality: Check the functionality of the fire sleeve by verifying that it fits properly over the hoses, wires, or cables that it is intended to protect. Make sure that the end fittings or covers are secure and that the fire sleeve is not binding or kinking.
4. Testing: Perform a test to verify that the fire sleeve meets the performance requirements for its intended application. This may include exposure to high temperatures, flame, or abrasion.
5. Documentation: Document the results of the inspection, including any damage or issues that were identified. This information can be used to track the performance of the fire sleeve over time and to plan for any necessary repairs or replacements.

It is important to follow proper safety procedures when conducting a fire sleeve inspection, such as wearing protective gloves and clothing and working in a well-ventilated area. Additionally, it is essential to follow the manufacturer’s guidelines and specifications for the specific fire sleeve to ensure that the inspection and testing methods are appropriate for the material and intended application.
