[2 Quick Steam engine questions]

The reason I question the steam engines exploding is I have a friend who plays the heck out of tekkit, and he insists that on 1.1.18 that steam engines cant explode

[2 Quick Steam engine questions]

Everything I have read said 2 things.

1, steam engines can be combined to become more effecient

2, steam engines can explode

Is both of this information correct? I am working on going to space, have my refinery running, but it is pumping in the fuel a lot faster than it is pumping out. I want to add 3-4 more steam engines to make it refine the fuel faster, but I am concerned about it blowing up. I went into creative mode and put 6 steam engines in a row attached to a pulverizer, and have just been waiting, and there hasnt been an explosion yet.

What mod is this part of? I tried looking at all the different mods on hexxit and couldnt find it. Im trying to figure out how to use it properly and identifying what mod added it would help out with that.
