TUNED PIPE REPAIR
This procedure is given to repair tuned pipe cracks
using T.I.G. welding process.
Procedure
– Sand the cracked area to obtain bare metal.
– Perform a 1.50 mm (1/16 in) depth chamfer
over crack.
– Use pure argon gas with 5.55 mm (3/32 in)
tungsten electrode (puretung “green”, zirtung
“brown”) and AC current.
– Use a 5.55 mm (3/32 in) aluminum welding rod
(no. 4043), to fill crack.
– Sand welding slightly to remove material sur-
plus.
Test
– Use compressed air at 124 kPa (18 PSI) to pres-
surize tuned pipe.
NOTE:
Prior to verify leaks, plug all holes and
pressurize tuned pipe while immerging it in water.
INSTALLATION
Installation is essentially the reverse of removal
procedures. However, pay particular attention to
the following.
