We can't make pipe hold more pressure but you can re-inforce it if it chooses to blow up on you, but its very dangerous and it will be alot better if you use pressure rated pipe, and you will feel 100x safer when shooting the gun knowing that your using pressure rated pipe not past its rating.

MrCrowley is right, there really is no way to make a piece of pipe hold more pressure. Embedding it in concrete would probably work, but would also make it completely useless.
There's some debate about double-layering pipe (by using couplers with the ridges filed out), but I don't think it would significantly increase bursting pressure. It's a bad idea to bet on.
As MrCrowley said, the best thing to do is to use pressure rated pipe.
People have tried everything you can think of to build a "shrapnel shield" around their chambers; some of these have actually created even more shrapnel rather than helping to contain it.
Do the smart, safe thing; save up the money for pressure rated parts, and call around/research until you find a local, reasonably inexpensive place to buy them. Try plumbing supply shops, irrigation/sprinkler shops, etc... not hardware stores.
Peace,
Pete Zaria.

like they just said, dont do it. Learn how to weld and use steel pipe, or use threaded brass pipe, both of which are probobly cheaper than four layers of pipe!

umm, why would you want to do that, i think that would cost like over 30 $ for 1 meter of pipe 
trying to decide on a new project, probably something small.

are you talking about the metal pipe or the four layer thick PVC
because metal pipe only cost a couple bucks a foot for three inch 8)

Whats the point? If its pressure rated and you stay below the rating its not going to blow. Or why wouldnt you just use the metal cylinder if its pressure rated?

These little techniques (sleeving, etc) might affect the burst pressure, but it is difficult to tell. Honestly, the best thing to do is to buy the material that fits your purpose. You don't see PVC fittings being used on high pressure hydraulic systems; why should you use low pressure fittings on a high pressure application?
