Sleeving

Matti: /* Direct insertion */

==Reasons==
<b>Sleeving</b> is a method of reinforcing pipe, typically thinwall [[PVC pipe]], by placing it inside a larger diameter pipe. For sleeving to be efficient, the outer diameter of the inner pipe needs to closely match the inner diameter of the outer pipe.

Another reason for sleeving barrels is to create more appropriate diameters for specific projectiles. For instance, if the barrel inside diameter is 2.00" and you have a slightly smaller projectile, another PVC barrel could be inserted inside the 2.00" diameter barrel. The resulting smaller diameter barrel would be an appropriate size for a golf-ball or other unusual projectile.

==Methods==
===Direct insertion===
Sometimes, there is a pipe diameter that matches the pipe you want to sleeve close enough to directly insert it. For instance, 1.5" nominal fits very well in 2" sch 80. Often it is glued, normally with a relatively slow-curing glue. However, the force required to cause the pipe to move sometimes makes this overkill.

===modified insert===
This is used in the situation that the pipe you want to insert is too big to do so.
Simply, a lengthwise section of the pipe is removed, allowing the diameter of the insert to be reduced. With much effort, it is then possible to shove this into the outer pipe; the effort required to do so is great that gluing it is unneeded.
