Ship foreign trade standard cbm1061-81 suction coarse water filter - seawater filter

When it comes to coarse water filter and sea water filter, we have this little question: Why are there so many executive standards? There are cb/t497-1994 suction coarse water filter and cbm1061-81 suction coarse water filter.
On this issue, let's introduce the difference between the two paragraphs:

Cb/t497-1994 is the design standard of a filter in our national standard; Cbm1061-81 coarse water filter is a foreign trade standard, which is exactly a filter that imitates foreign standards.
Cbm1061-1981 suction coarse water filter and seawater filter are designed by imitating the outline of JIS f7121 cylindrical seawater filter, and the flange size is in accordance with JIS b2221 5K.

It can be seen from the above picture that this marine suction coarse water filter cbm1061-81 is made of Q235-A carbon steel structure on the basis of conforming to JIS f7121 standard cylindrical seawater filter.
Then we will ask, since the structural dimensions are the same and the connection dimensions are the same, which of the two types of seawater filters is better?
The functions of these two types of seawater filters are the same. The difference lies in the production process and material wall thickness grade.

Below, we have made a brief introduction to the angle seawater filter and the right angle coarse water filter bl400 cbm1061-81 just delivered:
