Details Determine Quality

Focusing on details has been COFF people’s business idea. Every detail shall be paid attention to during poduction. In COFF workshop, all liners of tanks shall be welded at both sides. However, to guarantee the air tightness of weldings, dye-penetrant is required to be used to examine weldings. Each welding of each tank shall be conducted with the procedure.

Besides, all dished heads shall be protected by plastic film once delivered to the workshop for fear of being scratched during production.

Before shippment, all tanks shall be fixed well in the containers by tensioning belt and foundation belt to prevent from damage caused by waggling during shipping.
