Marine stainless steel coarse water filter - stainless steel
suction coarse water filter fh-a300s cb/t497-2012
Marine stainless steel seawater filter-316l stainless steel
seawater filter fh-a300s cb/t497-2012
Our factory successfully delivered marine pure stainless steel 316L
seawater filter and marine 316L stainless steel suction coarse
water filter
Now let's introduce this stainless steel coarse water filter
stainless steel sea water filter in detail:
First, let's take a look at the carbon steel galvanized suction
coarse water filter of common material proposed by the customer and
our company in 2019 (as shown in the following figure):
It can be seen from the physical drawing of the on-site coarse
water filter that with the on-site use and the corrosion of
relevant media, the surface and interior of this seawater filter
have been corroded to a certain extent.
This stainless steel 316L suction coarse water filter fh-a300s cb/t497-2012 model definition:
A- indicates that the stainless steel 316L rough water filter is of
straight through type, that is, the inlet and outlet flanges are
separated on both sides of the stainless steel rough water filter
and on the same horizontal line.
300 means that the nominal diameter of this 316L stainless steel
sea water filter is DN300 (300mm) and the applicable steel pipe od
is 325.
S-this type of coarse water filter is made of SUS316L stainless
steel, and its material brand is 022cr17ni12mo2 (New), and the old
brand is 00Cr17Ni14Mo2.
Cb/t497-2012: refers to the production structure, dimensions and ex
factory inspection standards of this stainless steel coarse water
filter and stainless steel sea water filter.

Production process and production drawings
This marine stainless steel coarse water filter - stainless steel
sea water filter is special:
1. on the basis of the ship standard (cb/t497-2012 suction coarse
water filter AS300), the wall thickness of the body is increased
from 8mm to 10mm to increase the corrosion resistance.
2. in order to match the bypass valve (butterfly valve) on both
sides of the pipeline, the connecting flange of this stainless
steel sea water filter adopts gb2506-2010 PN16 standard.
3. according to the actual situation on site, the customer changed
the filtering accuracy of the filter cartridge to 40 mesh (≈ 0.38 μ
m). According to the international standard Taylor standard screen
system, mesh-40 refers to the number of holes per inch of screen
mesh is 40. At this time, a problem arises: when we usually make
marine suction coarse water filter, the filter cartridge is rolled
with perforated plate, and the value of 0.38 μ M can hardly be
punched out. At this time, we reach a consensus based on our
experience and communication with customers:
On the basis of basket type filter, we lined 40 mesh stainless
steel mesh inside the filter cartridge of seawater filter by tin
welding to meet the requirements of customers.
4. due to the long-term consideration of the customer and the
convenience of future maintenance, they chose an identical spare
stainless steel filter cartridge for each stainless steel seawater
filter on the basis of the above to be used as spare parts in the
future.
5. in order to better serve customers, we have updated the exhaust
port and drain port (sewage outlet) of this 316L stainless steel
suction coarse water filter:
The original standard plug is replaced by a stainless steel 316L
manual ball valve, which is very convenient for customers to drain
or clean the filter cartridge in the future.
