Corrosive gas in a gas network leads to a crash as it tries to overload the network's steel pipes, which are apparently null

[9thCore]

Repro:

1. Tag any gas as corrosive under forge/tags/electrodynamics/gases/iscorrosive.json
2. Increase its pressure so it can explode any pipe type
3. Produce the now-corrosive gas
4. Add a pipe rated for less pressure than the network currently hosts
5. Crash

Test JSON: { "replace": false, "values": [ "electrodynamics:oxygen", "electrodynamics:hydrogen" ] }

admittedly i should have verified before opening the issue, but it does happen with just Electrodynamics as well, so its not a KJS incompatibility

Been playing around with this for a bit, and it seems like the cause is not related to corrosive gasses: it errors if a steel pipe type should explode as a result of the gas transfer, which just so happens to occur only when the gas is corrosive as the 100 pressure required to destroy a steel pipe cannot be reached(?). The NullPointerException is caused by conductorTypeMap.get(SubtypeGasPipe.UNINSULATEDSTEEL) being null. Still unsure why, however, as debugging seems to indicate it should be set up properly and exist no issue... EDIT: I forgot to mention how gas pressure should exceed the minimum pressure in the network, such that line 326 passes

Good catch.
