XLQ liquid heat treating process isn't some new
radical process that promises crazy weight saving with
standard tubes. Basically all heat treating processes
are the same, the product is put into an oven and
heated up which makes the frame stronger. Most of
the heat treatment ovens are heated with air which
is ne for most frames but with light weight frames it
can lead to all sorts of problems. The air that heatsthe oven will heat certain parts of it more than others
which will lead to some areas of the frames being over
heated and for too long leading to brittle welds or not
heated enough and leading to uneven tube strengths.
The heat treating we use heats the oven with a liquid
that is at a constant controlled temperature but is
also constantly circulating to avoid any temperaturechanges, this leads to a product that is perfectly and
evenly heat treated.

Helix tubing has been used for many years in other industries and is not a new revelation in steel
making. The only way to make 4130 lighter is to use thinner wall tubing or a magic process which has
not yet been created. Making these walls thinner to save those much needed grams leads to a whole
host of problems such as, weak and brittle welds, cracking of tubes and easily dented tubing.
Our helix tubing allows a thinner walled tube to be used not sacricing any of the tubes strength but
actually increasing the tubes strength.
The advantage of this tubing is, say you wanted the down tube on your frame as 34.9 in diameter and
3mm wall thickness the Severed Alliance Helix tube allows you to use a 2.7mm thickness but with the
other 0.3mm across the members of the inside of the tube saving weight but actually increasing the tube
strength.
In a few short words its 30% stronger and 20% lighter.
