This innovative, patent-pending bat-style pipe is made of stainless steel wire coils, precisely manufactured so that they attach by twisting/screwing. The coil pipe comprises 5 coils-two in the bottom (bowl) half, and three in the filter (top) portion. The two halves of the pipe fit together by twisting/screwing.
The stainless steel coil pipe has some interesting features:
The coil pipe has 100% stainless steel construction. There is no wood, aluminum, adhesive or any other material in this pipe (other than the ceramic filter, of course). Therefore, both top and bottom can be cleaned with solvents.
The coil pipe can be completely disassembled by hand, by unscrewing the steel coils. This means disassembly is easy, and each component can be cleaned separately. The ceramic filter can be removed, and hit with a torch to completely burn off soot if necessary. The glass sherlock VG, glass bat VG, and this coil pipe are the only pipes that have removable ceramic filters.
The coil pipe is thermally insulated, due to an air gap between the inner and outer coils. Therefore, the outser surface does not become hot. The coil pipe stays much cooler than the aluminum Bat VG.
The coil pipe uses flame heat very efficiently, since it is so well insulated. This makes it good to use in cold weather. It also means a slightly smaller flame can be used. The coil pipe tends to run hotter than our other pipes, since little heat is lost to the outer surfaces.
