Types of main breaks?

[Pump2005]

I'm having a brain freeze trying to find what a crack in a main is called. Most common we deal with is a circular beam break but what is a lengthwise crack called?

Longitudinal cracking

A split.

Thanks. Just seeming to think it had another name. A crew had one yesterday but the road valves didn't stop the flow so they had to do with clamping it on the fly. Since they weren't able to cut it out I figure they'll be back before the fall.
