Here are some key factors to consider when choosing the appropriate pipe fire collar:
1. Pipe diameter: The fire collar needs to match the diameter of the pipe it is protecting. Measure the outside diameter of the pipe and select a collar designed for that size.
2. Fire rating: Choose a collar with a fire rating that meets the requirements of your local building code. Common fire ratings are 1-hour, 2-hour, or 3-hour.
3. Material compatibility: Ensure the collar material is compatible with the pipe material. Common options include intumescent collars for plastic pipes and steel collars for metal pipes.
4. Annular space: Check that the collar can accommodate the annular space (the gap between the pipe and the hole/sleeve it passes through). This space should be within the manufacturer's specifications.
5. Installation location: Consider whether the collar needs to be exposed or concealed. Some collars are designed for surface mounting while others are made for recessed installation.
6. Ease of installation: Look for collars with features that make installation simple, such as split collars or collars with built-in retaining tabs.
7. Compliance: Verify that the collar is listed and approved by the relevant testing agencies, such as Underwriters Laboratories (UL) or Intertek, for the intended application.
Consulting the manufacturer's specifications and guidelines, as well as local building codes, will help ensure you select the appropriate fire collar for your pipe penetration application.
