.cA B S TRA CT This repor.t outlines the resting of ITT Grinnell's.;1:e 2A rigure 215 stiff clamp under an oven-hcate,d condition.
PURPOSE The purpose of this report is to identify any torge loss due
~
to temperature, TESTING..AP P A_R ATUS
' OLTRA Temperature oven, 760* farenheit capacity; L;.ds and North-e 1.ibrated rup speedor.ax recorder. 20000 farenheit capacity, October 21.'1982.
TES_T SET _UP The pipe clamp shall be secured around the pipe spc'1.
- A thermal couple shall be tack welded to the pipe spool to a: are that the 0
spool will reach a maximum t'emperature of 650 fare. helt.
Place the clamp in the oven and attach the thermal coupit to the re-corder.
PROCEDURE 1.
We' secured the pipe clamp around the spool wit!:
torque value s
of 40 foot.Ibs.
Our installation I'nstructic'ns adicate that 35 foot lbs. are required for the size 2A clamp.
We increased the torque by fifteen (15) percent in order to.imulate a pressurised pipe line.
2.
Place the clamp and spool in the oven..

s 'DISCU SSIO!!
J The results of the test were favorable in that the : was' no torque loss.
.This clearly.in'dicates that the clamps are capabl.- of with-standing a temperature of 65'O farenheit without.Using the
.,>neosesary torque; generated in our test deport PE 1.
Therefore, loss existed the max 1 mum recommen ad loads and
~
since no torque stiffnessen still' apply at 650 farenh'eit.
