8.3.2 installation of the tank bottom valve
Type 2105
For further information on containers and welding instructions,
please refer to the standard ASME VIII Division I.
It is recommended to weld the valve prior to the container
installation. However, it is possible to weld the valves to
ready-assembled containers.
prior to welding, please check to ensure that:
• The tank bottom valve does not collide with other equipment compo-
nents and assembly/disassembly of the actuator is always possible.
• A minimal distance between two welding joints three times the
thickness of the container wall is adhered to.
It is recommended to weld the valve in the center of the drain
to ensure optimum draining of the container.
The hole diameter in the tank and the housing flange must be the same
size. The housing flange has two welded edges to facilitate positioning
and welding of the valve. The welded edges are approx. 3 mm wide.
If the container wall is more than 3 mm thick, it must be ground down
so that the discharge surface is touching the housing flange surface.
Prior to commencing the welding process, check the charge
number indicated on the supplied manufacturer‘s certificate
3.1.B.
procedure:
→
Position the flange into the hole so that the flange surface is
tangent to the drain surface.
→
Tack 4 welding points and check the position of the valve.
→
Weld the valve evenly to the inside and outside of the container,
with gas being supplied and using welding material compatible
with the valve‘s stainless steel 316L (DIN 1.4435).
→
Allow the welds to cool down before burnishing and cleaning
them according to the applicable specifications.
These instructions assist in the installation of the tank bottom valves and
allow the prevention of deformation and softening within the containers.
Please observe the applicable laws and regulations of the
respective country with regard to the qualification of welders
and the execution of welding work.
