6. HYDRAULIC TEST OF BARREL
ď˝
ď˝
The barrel complete with internal fittings
including Master Valve & Bottom discharge
Valve after being mounted on the under
frame shall be tested HYDROSTATICALLY
to pressure 2.8 Kg / cm. sq. against
leakage of longitudinal and circumferential
weld seams of Barrel along with fitted
valves.
The pressure is maintained for 30 Minutes
(min.).
7. A BREAK THROUGH TECHNOLOGY
The newly designed tank barrel is inclined at 1
deg towards discharge points to facilitate easy
flow of
POL Products.
8. ď˝
The wagon is manufactured from:
⌠SAILMA 350
⌠IS: 8500 Fe 570B
These high strength micro alloyed steels have higher
yield strength, higher notch toughness, good fatigue
properties, excellent weld ability and good formability.
