Re: Tank Car Steam Connections
Well, at least I see this. I was close, but not exactly
correct. See for example this UTLX patent heater from the
1930's
It appears that the steam goes out in the small inner pipe and
returns as condensate after giving up its heat in the larger outer pipe to the
header and is discharged.

This is partly a
test message. We have been on vacation for a week and had an Inbox
overflow issue, so I am not sure what I missed or what has gotten
out.
Anyway, all of
the tank car heater configurations I have seen in my UTLX research have had both
an inlet and an outlet. Most single compartment tanks have them through
the center sill near the main unloading pipe. Multi-compartment tank cars
generally have the inlet and outlet through the tank end. There are many
different patented pipe configurations and a central header from which the
heater coils radiate. John Van Dyke patented one of the early one for UTLX
and they held several others.
If I am interpreting
Dennis' original question correctly, he is referring to the photo of UTLX 56816
being unloaded into a road oil sprayer, that I think Doug Harding shared some
time ago. In this groups files is a 1952 listing of tank cars from UTLX,
which Richard Hendrickson originally shared many years ago. For a given car
number, you can see the nominal capacity, the car class and the type (if any) of
heater it contained. 56816 was a 10000 gallon Type Z car (looks like
a GA type 17 tank car.) According to this list, 56816 has a Type L heater
inside. According to the table at the front of that listing, the Type L
heater had a single header with 6 runs of 3" pipe. It says that there is a
1/2 inch inside pipe, which I could interpret to mean the cooler returning steam
to the header. This car does not have a steam jacket around the
nozzle. It lists the inlet pipe as 1-1/4 inch and the outlet as 1
inch.
I hope that this is
helpful and that it actually gets through.

Hello Steam Era Modelers: We are pleased to announce that Westerfield Models has a new Kit available: Our newest HO Kit release is the #12400 Series USRA DS Express Box for Northwestern Pacific. These 22 Express service cars were rebuilt from the 100 USRA DS box cars (#1900-1999) allocated to the NWP in 1919. The cars were originally rebuilt into express service in 1939 (Westerfield Kit #3818) but the service was discontinued during WWII. In April, 1949, the cars were rebuilt with passenger steam, signal and air lines, and passenger style low uncoupling levers and retainer. They were repainted with the famous “Redwood Empire Route Overnight” lettering. These cars were painted SP Dark Olive Green with black roof, underframe and trucks. Our #12400 Series ONE-PIECE Body Kits cover the 1949 version of the Express Service box car with NWP’s “Redwood Empire Route Overnight” lettering scheme as well as passenger style steam and signal lines. This colorful lettering is accurately reproduced with our multi-color decal set. The 1939 NWP Express Service box car is also available as our Kit #3818. The 1946-1960 Freight version box car is available as our Kit #3858. Our unpainted HO Kits include detail parts appropriate for the NWP Express Service version, including the following details: Improved Cast Urethane One-Piece Body Construction with Fine Details. Urethane Castings of detail parts, including many car specific parts. Plastic Steam, air and signal hoses. Yarmouth Etched Bronze Corner Steps. Full Color Proprietary Decals covering the 1949 Express Service versions of the car. Detailed Step by Step Instructions and History Sheets with assembly and finished model photographs. Recommended Trucks: Tahoe Model Works TMW-112 or TMW-212 Andrews Trucks. Tahoe TMW-112 (Code 110) or TMW-212 (Code 88) Andrews Trucks available separately or with Kit (See below).

I have seen ACF drawings of heater coils. One has connections through the tank head - two each inlets and outlets, i.e. an inlet and an outlet for the left set of coils and a pair for the right set.

The other drawing had one inlet and one outlet through the bottom of the tank and through openings in the center sill cover plates. Lou Whiteley Lawrenceville NJ

I have photos of the inside of an ATSF storage tank at Emporia with the large heating lines inside that tank. Santa Fe tended to drain the oil out of the cars into wood lined troughs between the rails and then pump it into the large tanks for storage.

Jack, If you are commenting on my road oil tankcar, they are not introducing steam into the oil, but rather into the heating coils, which are a closed system. What Chuck is saying is you don't need to vent steam out the other end of the coil; as the steam gives up its heat, it condenses to water, which trickles down to the steam trap, where it is expelled from the system, same as a passenger car heating system, or, for that matter, my building heating system. If I recall the function of the steam traps correctly, they have a bi-metallic diaphragm that when covered by water, cools enough to pop open. With the water gone and steam flowing by, the diaphragm heats up enough to pop closed again.
