Ancloz Fire Protection Jackets

Flexible, industry-specific specifications

Our three different types of jackets give us the flexibility and range to serve our customers’ protection needs and specifications in a large variety of markets, from Oil and Gas all the way to Nuclear technology. With our versatile products, along with our expertly trained team, we can respond to the specific challenges presented by each individual industry; down to sector-specific requirements including fire type, fire rating/duration and the internal/operating temperature of the protected component.

This expertise, coupled with our passion to serve and our commitment to protect, has enabled us to achieve a new milestone in flexible and removable fire jacketing systems.


Proven jet fire protection

JETFLEX is a flexible fire-protection jacket that is proven to provide hydrocarbon and jet fire protection for up to 120 minutes. Each JETFLEX module is designed to snuggly fit a myriad of valves, actuators, control panels, pressure vessels, condenser stabilizers and pipes.

Furthermore, this flexible jacket is composed of lightweight materials that allow for easy installation, making it a leading product in the marketplace.

Acoustic & thermal protection, combined

This acoustic jacketing system doesn’t just reduce sound from the system it covers, but also has thermal insulation properties – all in a singular modular system. This is due to the various layers of acoustic and thermal insulation, all wrapped with a silicon coated cloth. With all these layers packed tightly, the product is both easy and cheap to manipulate for maintenance. It is held in place via a buckle and square-ring system, or steel band fixing.

High temperature personnel protection

This insulation jacket protects working personnel from even the hottest of equipment. With the flexible jacket expertly tailored to fit any type of shape, it will be able to accommodate any client’s design request and still be able to function with maximum efficiency; protecting the users around the equipment. Furthermore, for items that need to remain at a relatively higher temperature, our thermal jackets can also keep the heat contained within the pipe – significantly slowing down the escape of heat to the environment.

Effective & Convenient

Ancloz jackets feature some of the best materials in heat and sound protection technology, including high-temperature resistant cloths, marine insulation blankets, stainless steel mesh, hydrophobic-microporous insulation material and stainless steel thread stitching – melded together into products of the highest durability. This allows the jackets to withstand rain or shine, even while protecting our clients out in the open environment. For the convenience of our clients, these jackets are also uniquely designed in each circumstance to allow easy removal and assembly, should the need arise.

Despite the high standards of our existing products, our design team is still continuously innovating and seeking every possible means to enhance the protection that our jackets offer our customers.

Production Process

Due to their versatility in design, Ancloz jackets have a wide variety of applications in the various markets that they aid in protecting. For each application that requires protection, Ancloz will send a team of engineers to the site in order to obtain a detailed analysis of the site and factor in any background interference such as control panels, protruding pipes or any other services into the design of the jacket.

This information will then be transmitted back to the factory, where our designers will either create a new jacket or edit their existing hypothetical drawing designs.

Following this, the primary drawing will be sent to the client for their approval or any specific request or comments. From that, the jackets will then be made and will be shipped to the desired location as soon as possible. Installation of the jacket itself can either be done by the client or by our expert engineers.

Our production process allows for complete flexibility, as it enables our jackets to be perfectly fitted regardless of any irregularities that may occur.

Securing Methods

For securing the jackets together, we use various methods depending on the orientation; including square-rings, ss316 stainless steel bands and lacing wires. These are used to tightly secure the flaps, which minimises the area which heat can directly penetrate the jacket. This therefore leads to greater protection of the item contained within the jacket, by significantly slowing the rate of heat transfer to the protected item.
