Above Ground With High Acid And Alkali Resistance Glass Lined Liquid Storage Tank

How is the production process of GFS tank ?

1. Get raw steel sheet : First measure the thickness with micrometer and see whether it matches the raw steel sheet to be used . Then mark down the batch number .

2. Punching , corner cut and edging : Before punching set all the dates as per drawing in the computer and then put steel sheet on the automatic laser cutting machine , which will cutting the holes according to the setting datas .

3. Press Arc :According to the diameter , determine the radian of the pressure plate ; clean up the pressure machine and the plate surface ; be careful do not press the steel emery onto the plate .

4. Short blasting : Before the blasting , shifting the steel emery ( steel grit) and add it to the blasting machine ; hoist the rough steel into the blasting machine.

5. Glaze Mortar Adjustment : Firstly , the ground coat glaze mortar must be shifted . Secondly , adjust the glaze mortar according to the specification .

6. Spray : Before the spray , check the plate is clean and no defects , use sandpaper to clean the surface well and then put them into the automatic spray machine , start spraying .

7. Buring : After finish spray put the steel sheet to the high temperature oven , the burning temperature between ground enamel and top enamel are different . The temperature of ground enamel is 880-900 degree and the buring time is about 8-20 minutes , while the top ground the temperature is 780-820 degree and the burning time is about 6-16 minutes .

9. Production QC : chemical elements inspection ; holiday test ; Coating thickness gauge ; Out appearance checking ; Anti-acid&alkaline test ; Anti-high temperature test ; Adhesion test ; Adhesion test

10. Package : Double checking is required before packaging, confirm the plate’s code and quality . The steel plates is separated with each other by PE foam , to avoid any damage on the coating surface . And the whole pallet steels are covered by a outer film, tied by steel belt .
