Reclaim from a pipe used for combustion is different than a pipe used for vaporizing. I don't recommend reclaiming from a combustion pipe, though I have done it to see if I could.

The reason I don't recommend it, is because of the free radicals produced as byproducts of pyrolysis. When you only partially combust a molecule, it turns into something else, some of which are carcinogenic.
Vaporized concentrate on the other hand, hasn't been combusted, and should be no more prone to produce them than the short path distillation process typically used to purify concentrates.
I did drop my vapor pipe by the pharm for cleaning, and asked for a sample to be sent to the lab for analysis on my nickle. I'll pass on the results when I receive them.
For what its worth, for the last several years I supply my vapor pipes for reclaim, which is highly prized by some of our patients for their sedative qualities.
