5. Sealing and strength test standard: strength and sealing test standard:
GB/T 4213-2007
Hard sealing grade: if the user has no special requirements, the standard in the table below can be followed. If the user requires, the standard of GB / T 4213-2007v can be followed.
The strength test pressure is 1.5 times of the nominal pressure, and the sealing test at the packing and flange is 1.1 times of the nominal pressure The valve seat seal is tested according to the maximum service pressure difference. When the maximum service pressure difference is not clear, the test is conducted according to 1.0MPa (hydraulic pressure). When the maximum pressure difference is less than 0.6MPa, the test is conducted according to 0.6mpal pressure. The medium is water with corrosion and scale inhibitor
