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
components 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 diameter of the hole in the container and the flange must be equal.
The valve has two welding edges to make welding and positioning of
the valve easier. The length of the welding edges is approximately 3
mm. In case the thickness of the container wall exceeds 3 mm, the
valve must be positioned as shown in Fig. 27:.

Prior to welding the valve, grind the outlet wall.

Prior to commencing the welding process, check the charge
number indicated on the supplied manufacturer's certificate

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.
