Description

ArmaProtect EFC1 and EFC2 represent an innovative and flexible solution for critical firestop pipe penetrations, ensuring enhanced safety in buildings. These endless firestop collars are ingeniously designed to accommodate a wide range of pipe diameters and design variants, providing versatile passive fire protection. Constructed with a robust stainless steel strap and a self-adhesive, flexible intumescent strip powered by advanced blowing graphite technology, these collars react to heat by expanding significantly (18 to 34 times, with expansion pressure > 0.8 N/mm² starting above 190°C) to seal gaps around pipes during a fire. This crucial action prevents the spread of fire and smoke through penetrations. Gitco-sa.com, as the authorized Armacell distributor in Saudi Arabia and Bahrain, is proud to supply this essential fire safety product across the region, serving major cities like Riyadh, Jeddah, Dammam, Manama, and more.

ArmaProtect EFC1 and EFC2 offer impressive fire resistance for various elements of construction: up to EI 120 for drywall, concrete, aerated concrete, and masonry walls, and an outstanding EI 240 for concrete floors (EN 13501-2). They are suitable for use at temperatures below 0°C with UV exposure but no rain (Type Y1, EOTA TR 024). The collars are designed for an operating temperature range of -40°C to 70°C, with an optimal processing temperature between 5°C and 25°C. The stainless steel collar achieves a Reaction to Fire Class A1, while the intumescent strip is Class E (EN 13501-1). These solutions contain no dangerous substances and offer the benefit of “no shelf life” for the product itself when stored correctly (cool, dry, protected from frost), providing long-term reliability for your passive fire protection systems.

Key Features of ArmaProtect EFC1 and EFC2:

• Flexible Endless Collars: Adaptable to various pipe diameters and configurations.
• Intumescent Technology: Utilizes blowing graphite for significant volume expansion (18-34x) to seal gaps in fire.

• Robust Material: Stainless steel strap ensures durability and integrity.
• Wide Operating Temperature: Effective from -40°C to 70°C.
• UV Resistant: Suitable for conditions with UV exposure (Type Y1).
• No Dangerous Substances: Safe for installation and long-term use.
• No Shelf Life: Ensures product viability over extended periods when stored properly.

Product Variations of ArmaProtect EFC1 and EFC2:

ArmaProtect EFC1 and EFC2 represent different versions or sizes of these endless firestop collars, likely optimized for varying pipe diameters, wall/floor types, or specific fire rating requirements. While the specific distinctions between EFC1 and EFC2 are not detailed here, they provide flexibility to address diverse installation scenarios. These collars are designed to be cut to size on-site, making them a highly customizable solution for pipe penetrations in different building materials. For precise guidance on which variant (EFC1 or EFC2) is suitable for your project’s specific pipe sizes and fire rating needs in Saudi Arabia or Bahrain, please consult Gitco-sa.com.

Technical Specifications & Features

Q1: What are ArmaProtect EFC1 and EFC2 firestop pipe collars?

A: ArmaProtect EFC1 and EFC2 are “endless” flexible firestop pipe collars designed to provide robust fire protection for pipe penetrations through walls and floors. Unlike rigid, fixed-size collars, these endless wraps can be cut and sized on-site to fit a wide variety of pipe diameters and complex layout configurations.

Q2: What materials are used in the construction of ArmaProtect EFC?

A: The system consists of a high-grade stainless steel strap paired with a self-adhesive, flexible intumescent strip. The intumescent material utilizes advanced blowing graphite technology to achieve its fire-stopping performance.

Q3: How does the “blowing graphite technology” work during a fire?

A: When exposed to heat during a fire, the graphite-based intumescent strip undergoes a rapid chemical reaction, expanding significantly in volume (intumescence). This expansion generates high pressure that completely crushes and seals plastic pipes as they melt, preventing the passage of flames, smoke, and toxic gases to adjacent compartments.

Q4: What is the difference between ArmaProtect EFC1 and EFC2?

A: While both utilize the same high-performance intumescent technology, the primary difference lies in their application scale, strap width, and the thickness of the intumescent layer. EFC1 is typically optimized for standard, smaller-to-medium pipe diameters, whereas EFC2 features a heavier-duty profile designed to handle larger pipe diameters or more demanding fire resistance ratings.

Application & Installation

Q5: What pipe materials are ArmaProtect EFC collars compatible with?

A: They are primarily designed for combustible (plastic) piping systems such as PVC, PE, PP, and ABS. They can also be used on insulated non-combustible pipes where the insulation itself poses a fire spread risk through wall or floor penetrations.

Q6: Can these flexible collars be used for both wall and floor penetrations?

A: Yes. ArmaProtect EFC1 and EFC2 are versatile solutions certified for use in both lightweight drywall/solid masonry wall assemblies and concrete floor slabs, ensuring continuous compartmentalization.

Q7: Why are they referred to as “endless” firestop collars?

A: They are called “endless” because they are supplied in continuous rolls rather than pre-sized rings. This allows installation teams to pull, measure, and cut exactly what they need for any given pipe size, significantly reducing material waste on the job site.

Q8: How does the flexible design benefit complex on-site installations?

A: Standard rigid collars require perfectly circular pipes and flat surfaces. ArmaProtect EFC’s flexible stainless steel strap can easily conform to tight spaces, corner penetrations, slightly deformed pipes, or unique structural configurations where traditional collars simply won’t fit.

Supply, Procurement & Compliance

Q9: What are the main inventory advantages of using an endless collar system?

A: For procurement managers and contractors, stocking ArmaProtect EFC1 and EFC2 drastically reduces inventory complexity. Instead of sourcing and storing dozens of different fixed-diameter collars, you only need to stock a single roll system that accommodates virtually all pipe sizes on-site.

Q10: Are ArmaProtect EFC collars resistant to environmental factors?

A: Yes. The stainless steel strap offers exceptional corrosion resistance, making it ideal for industrial or high-humidity environments. Additionally, the intumescent strip is formulated to resist moisture and atmospheric exposure, ensuring long-term reliability without degrading.

Q11: What testing and certification standards do these firestops meet?

A: ArmaProtect EFC systems are tested and rated according to stringent international fire safety standards (such as EN or ASTM/UL standards, depending on regional classification). They provide reliable fire resistance ratings (EI classification) to match the structural fire integrity of your project.

Q12: Where can I source genuine ArmaProtect EFC1 & EFC2 collars in the GCC region?

A: Genuine ArmaProtect EFC1 and EFC2 endless firestop collars are supplied by Gitco. Gitco offers specialized technical support, bulk procurement options, and logistics delivery tailored to industrial, infrastructure, and commercial construction projects across the region.
