Here's a message from Martin Nowak:
In September, Roberts Park Fire District acquired a Ford F-350/Wheeled Coach ambulance to serve as a second spare unit. It's labeled 3R2, following the current spare unit, which is 3R (a 2008 Ford F-450/Osage that was previously 308 and then 31). This new ambulance came from Virginia and was purchased as a backup unit. It had only 32,000 miles on the odometer when it was bought.

Roberts Park recently sent Ambulance 32 to Osage for a rechassis. The 2009 Ford E-450/Osage received a new chassis, which is a 2013 or 2014 Ford E-450/2009 Osage. The new chassis currently lacks the RP logos on the doors, but I believe they will be added soon. The last image shows the old chassis.

Special-shaped steel pipe is a type of steel pipe. It can be said to be a general term for seamless steel pipes with other cross-sectional shapes except round pipes. There are many types of special-shaped steel pipes. The three most common ones are special-shaped seamless steel pipes with equal wall thickness, special-shaped seamless steel pipes with unequal wall thickness, and special-shaped seamless steel pipes with variable diameters.
Special-shaped steel pipe uses
Special-shaped seamless steel pipes are widely used in various structural parts, tools and mechanical parts. Compared with round pipes, special-shaped pipes generally have a larger moment of inertia and section modulus, and have greater bending and torsion resistance, which can greatly reduce the weight of the structure and save steel.
Special-shaped steel pipes can be divided into oval special-shaped steel pipes, triangular special-shaped steel pipes, hexagonal special-shaped steel pipes, rhombus special-shaped steel pipes, octagonal special-shaped steel pipes, semi-circular special-shaped steel pipes, unequal hexagonal special-shaped steel pipes, and five-petal plum blossom shaped special-shaped steel pipes, double convex special-shaped steel pipe, double concave special-shaped steel pipe, melon-shaped special-shaped steel pipe, conical special-shaped steel pipe, corrugated special-shaped steel pipe.
