Abstract
A fabricated packed pipe coupling gland suitable for a connection where there is at least one brittle pipe, the coupling forming a pressure tight, leak proof coupling which is semi-rigid. The coupling is particularly useful for coupling glass pipe to metal pipe for conveying highly corrosive vapors at high temperature, for example heated titanium tetrachloride vapors to a reactor for forming titanium dioxide.
Claims10
Pipe coupling means for coupling brittle pipe comprising a outer metallic sleeve means having a flange at each end, means on one of said flanges to form an immovable connection to other conduit means, a plurality of packing rings within said sleeve, at least one metallic lantern ring means interspersed in said packing rings, means to continuously admit a purge gas to said lantern ring under pressure greater than that within said brittle pipe, packing retaining means within said sleeve adjacent one of said flanges, a flanged metallic follower sleeve means fitting within said outer sleeve, said coupling means receiving a brittle pipe of less outer diameter than the inside diameter of any metallic means, means connecting said follower flange to said other sleeve flange means to urge said follower against said packing and said packing against said packing retaining means, said means providing sufficient force to expand said packing thereby holding said brittle pipe in spaced relation from said metallic means.
