The COFF people have always focusing on every detail of product and highly valueing product quality. "Details deternmine succuess or failure" has been one of COFF people's highest values.

Though most customers require 0.3MPa for hyfraulic test pressure of jackets and 0.1 for air tightness of tanks, the COFF people make it 0.45MPa for hydraulic test and 0.2 MPa for air tightness, with holding time from publicly accpeted 4~8 hours extended to at least 12 hours, in order to improve the safety grade. What's more, in 2021 all hydraulic test pressure of tanks shall be set at 0.6MPa.
