How to install Stainless steel water tank ? Please see the following steps:
Step 1: Install the base channel basis
First, correct channel base diagonal size to ensure each base size of inner square being 970mm. Weld the skid base together with the fixed angle iron. Check the base is horizontal or not after welding is completed. If not, increase the iron piece and keep base pad be horizon.
Step 2: Install the tank bottom panel
Put the bottom panel on the skid base, ensure on each side of the panel is on the base and then spot welding.
Step 3: The tank side panel welding
Firstly fix four corners of each plate and weld. Welding should serious and careful to ensure no missing point(voids). Then, put each side panels together on the flat according the thickness. Plate angle to align together to ensure that the appearance of tank plate flat and neat, then weld.
Step 4: Installation of the side panel with bottom panel
Erected the tank four whole side panels on the floor, side panels align at bottom panels. Fix them by spot welding, then weld four sides integrally .
Step 5:Lacing bar welding inside the tank
Lacing bar weld at the two opposite tank side of the cross. Each cross has a main lacing bar; four auxiliary short lacing bars connect the side tank with the main lacing bar; the distance between the side panel and the welding point on the main lacing bar is 500mm. Each head main bar has four auxiliary short bar.
Step 6: welding tank cover panel
The cover panel connections is same with third steps, spot welding side panel and cover panel from inside. Each cross of the cover panel(bottom panel) weld support(bracing). Just a support stick, no auxiliary lacing bar.
Step 7: internal weld treatment tank
After finish of welding tanks, wipe special decontamination cream at each weld place.
Rinse it after ten minutes in order to avoid corrosion caused by poor water quality.
Step 8: The tank flange welding
First mark the flange place. Put the flange on the panel, use the pencil mark the flange diameter. Second, remove the flange, use the welding machine to increase current, penetrate panel. Connect point of hole into line. finally finish remove the flange hole.
Notice: the hole diameter must be a lesser than real flange diameter to forbid leak.
Step 9: welding tank ladder
Inside ladder placed the inner tank, weld the outer ladder near manhole side.
