3. WELDING THE BOTTOM FLANGE
• When the position has been decided, a hole for the 220 mm bottom ange is cut in the hull.
• The bottom ange, Item (1), is welded into the hull. Standard welding practice, methods and procedures
should be observed, but may vary. (See welding notes).
Attention:
The bottom ange is a part of the Sea Valve that is machined with high accuracy and it should be
protected after mounting to avoid damage to the bottom ange surfaces. This to avoid leakage. If the
valve is pre-mounted, be sure to protect the valve from being polluted by welding debris.
WELDING NOTES!
All bottom parts and anges for welding are precisely machined parts. During welding of these parts
to the ship’s hull plates, careful attention must be paid to avoid construction strain on the bottom
parts and anges.
• Let parts cool down during welding.
• Over heating may change t and form and result in non-conformity with intended sensor/
transducer.
• Welding to thick hull steel plates will exert high stress on bottom parts and anges.
• Especially care must be taken during welding of stainless steel anges.
• Work must be performed by a qualied and certied welder.
