The Flat Face Flange has a gasket surface in the same plane as the bolting circle face. Applications using flat face flanges are frequently those in which the mating flange or flanged fitting is made from a casting.
Flat face flanges are never to be bolted to a Raised Face Flange. ASME B31.1 says that when connecting flat face cast iron flanges to carbon steel flanges, the raised face on the carbon Steel Flange must be removed, and that a full face gasket is required. This is to keep the thin, bittle cast iron flange from being sprung into the gap caused by the raised face of the carbon steel flange.

Hi there,
I recently came across some interesting information about an ambulance from Life Line Emergency Vehicles on lifelineambulance.com. It belongs to the River Forest Fire Department and caught my attention due to its specifications and features.
The vehicle has a reference number of 5509 and is a Superliner Type III model. Jefferson Fire & Safety is the dealer responsible for this unit. The module size is 167 inches, and it offers a generous headroom of 74 inches, which is quite impressive. Under the hood, it’s equipped with an E-Series chassis, specifically the E450 type, ensuring both durability and performance.
Attached are some photos taken by Life Line Emergency Vehicles (credits in the captions). These images really showcase the design and build quality of the ambulance. It’s clear that a lot of thought went into making this vehicle functional yet practical for emergency services.
It’s always fascinating to see how these vehicles are customized for specific departments. Thanks to Martin for sharing this info—it’s great to learn more about the different setups out there. If you’re ever in River Forest or near Chicago, it might be worth checking out their fleet in action—it’s pretty cool!
Take care,
[Your Name]
