That's a standard tool used by plumbers (water fitters). It'll cost
about 5 usd here for 12mm dia copper tube. The larger ones are
slightly more expensive. Any (well-equipped) hardware-store will
have these.
btw: instead of filling the tube with sand - how about a LIQUID? First
you weld the other end shut (the inner end in final coil - if spiral)
and
then connect a cheap valve to the other end. Now, you fill the tube with
water and close the valve.. Should work fine.
