delivered worldwide at competitive prices.
As to given measurement or template ØRKILD can deliver keels
with stanless steel
bolts in threadholes in flange.
Keel design: OBS
Experience shows that difference in thickness can create important 50 % or more in
variation of mechanical strength in comparison with mechanical strength given in
ØRKILD therefore recommands calculating:
- - - - - -- - EN-GJL-200: 80-200 N/mm²
- - - - - - .- EN-GJL-250: 160-250 N/mm²
Above is recommanded on background of technological test, and refers to a thickness
of 155 mm. and a modulus < 2.25, to be read in DS/EN 1561 2004 standards.
