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.
