life duty cycle. Although, stainless steel
penstock having the low head limitation,
Trisuria Heavy duty stainless steel can
double up the head level with higher leakage
resistance as well. The structural design and
leakage requirement is accordance with AWWA

The Stem guide spacing shall not exceed and l/r
ratio of 200.
Muff couple
is cast by stainless steel and joint by locking
