Today, we will discuss with you how to measure the exact size of a certain seawater filter in the ship's pipeline system if it needs to be replaced when our ship is in dock for maintenance, so as to ensure the smooth installation of the new seawater filter.
Let's first look at the corroded Original Seawater filter on the ship:
Because the auxiliary equipment has been working for a long time, its body and filter cartridge have been corroded and cracked to a great extent. It can no longer maintain its work, so we need to replace it.
First, we need to measure several key data:
The section distance from the flange of the seawater filter to the flange is directly related to whether the newly made seawater filter can be smoothly installed in the pipeline system.
The distance between the bottom of the seawater filter and the center of the connecting flange is related to the height of the installation space.
Relevant dimensions of inlet and outlet flanges of seawater filter, including flange outer diameter, flange center distance and flange bolt hole size.
Hole diameter of the filter barrel inside the seawater filter.
Through the above measurement, we draw the production drawing according to the value provided by the customer:
Let's look at this new seawater filter from various angles.
The seawater filter of DN100 can be generally marked as:
Marine suction coarse water filter as100 CB / t497-2012
Right angle suction coarse water filter for marine seawater cooling system as100 CB / t497-2012
Main engine seawater pump inlet straight through seawater filter as100 CB / t497-2012
As100 CB / t497-2012 bulk seawater pump inlet straight through coarse water filter, seawater filter

Seawater filter with MGPS anti marine biological device
Today we will introduce a special seawater filter to you. As you can see from the above figure, this seawater filter is different from what we usually see. It is equipped with MGPS marine biological protection device.
With the navigation work of the ship, the seawater system on the ship will be corroded and polluted by the body of marine attached organisms, and due to the blockage of seawater inlet, filter, cooler, etc. by marine organisms, the diameter of seawater pipeline will become smaller, affecting the seawater flow and reducing the heat delivery rate, affecting the waste of cost and resources, and affecting the normal operation of relevant equipment.
In recent years, with our understanding of this hazard, marine seawater filters with MGPS anti marine biological devices have been widely used in many new ships.
Below, we will briefly introduce a seawater filter with MGPS anti marine biological device manufactured for customers:
First, we determine the parameters of the seawater filter to be installed:
As type, nominal diameter DN350, working pressure 0.6MPa, design pressure 1.0MPa, body material - carbon steel hot galvanized, filter cartridge material - SUS316L stainless steel, inlet and outlet connecting flange PN10
Secondly, we select the parameters of MGPS protection against marine organisms according to the protection service life:
Seawater flow: 900m ³/ h. One copper electrode and one aluminum electrode, power supply mechanism: 220V / 50Hz, protection period - 5 years.
We look at the physical picture of this seawater filter product with MGPS anti marine biological device from multiple perspectives:
Finally, let's introduce the operation and daily maintenance of this MGPS on board:
1. During the daily inspection of MGPS, the operator shall first read the meter and record the parameters of MGPS.
2. Pay attention to the change of the output current value when the seawater pipeline system is vented. When the salinity is too high or the seawater temperature is too high, the output current will become large. In order to reduce the consumption of the anode, the set value should be adjusted to change the current output. At the same time, the chlorine content in the seawater should be measured to meet the minimum standard for preventing the derivation of marine organisms.
3. Adjust the output current to be constant according to the current flow concentration chart given in the manual. When sailing in the freshwater area or in the freshwater river sea water mixing area, the decrease of the conductivity of water will also lead to the increase of current. On the other hand, the excessive production of sodium hypochlorite will aggravate the generation of magnesium hydroxide (i.e., the white paste attached to the MGPS electrode body during cleaning). At this time, it is necessary to turn off the MGPS. In addition, it is also necessary to turn off the MGPS during hull welding.
