Common Design Standards of Marine Valves
Marine valves play a vital role in ship and offshore engineering. To ensure their safety, reliability and compatibility, various standards have been developed in different countries and regions. These standards cover the design, manufacture, testing and performance of valves. Mainly include: GB, JIS, DIN, ANSI, CB, CBM.
Overview
At present, there are four main standards for valve production and selection: DIN, ANSI, GB, JIS
1. DIN
DIN is the European standard (also called German standard), the full name in English: Deutsches Institut fur Normung, corresponding to the Nominal Pressure PN, the full name in English: Pressure Nominal, such as PN10/16/25, PN is the nominal or formal pressure, not the actual pressure.
2. ANSI
ANSI is the American Standard, English full name: American National Standards Institute, corresponding to the pound class (LB), the unit of LB, such as ANSI 150LB.
3. GB
GB is the national Standard, English full name: Chinese Standard, and the European standard is basically the same.
4. JIS
JIS is Japanese Industrial Standards, and the corresponding pressure is K, such as JIS5K/10K/15K.
5. CB & CBM
In addition, there is CB (CB standard formulated by China State Shipbuilding Corporation, which is specially used in the field of ship and ocean engineering). CBM standard is a standard for Marine equipment and components formulated by China Classification Society of Shipping (CCS).
These standards play an important role in the design, manufacture and testing of Marine valves to ensure reliable operation under harsh conditions such as high pressure, high temperature and corrosion.
