MARINE LOW-PRESSURE CRUDE OIL FILTER, MARINE DOUBLE LOW-PRESSURE CRUDE OIL FILTER A50 0 0.25/0.16 CB / T425-94

Today, we will introduce a filter equipment in the marine fuel pipeline system - dual oil filter and dual low-pressure coarse oil filter.

First, we understand the installation environment of this dual low-pressure crude oil filter:

As can be seen from the above figure, this dual coarse oil filter is a coarse filter installed at the inlet of the ship's fuel transfer pump, which coarse filters the fuel and then distributes it to other equipment for work.

When we replace this crude oil filter, we need to confirm the following points:

1. Accurately measure the section distance of the inlet and outlet flanges of the double low-pressure crude oil filter (as shown in the figure).

2. Measure the flange size at the inlet and outlet, including the flange outer diameter, flange center distance and bolt hole size (as shown in the figure).

3. Measure the installation base of the dual fuel filter, including the longitudinal installation center distance, horizontal installation center distance and bolt hole size (as shown in the figure).

Based on the above measured values, we have drawn formal production drawings and confirmed with the customer:

After we have determined the overall dimensions and connection dimensions of this dual crude oil filter, we also need to confirm an important data - the filtering accuracy of the filter barrel inside the oil filter:

Once the above data are determined, we will start production and processing.
Let's briefly introduce how our factory processes this dual crude oil filter product:

1. We will arrange the processing of semi-finished blanks according to the number of orders.
2. Then we began to assemble this double low-pressure crude oil filter

3. After the double crude oil filter is organized, we start the pressure test

4. After the pressure test is qualified, we start to make the filter element of the oil filter
5. After the above steps are completed, we conduct surface treatment and can choose the coating color according to the customer's requirements

6. Finally, we carry out corresponding external packaging according to the customer's remarks in the order - packaging.

Low pressure crude oil filter AS40 cb/t425-94
Duplex low pressure crude oil filter as4040 cb/t425-94
Duplex switchable fuel filter as16040 cb/t425-1994

It can be seen from the title that cb/t425-1994, a national standard low-pressure crude oil filter, has many names. This is named according to the habits of customers in various regions.

Here we will give you a brief introduction to the dual low-pressure crude oil filter of Dn40 in this standard:
Model definition:

Type A - straight through type, that is, the inlet and outlet flanges of this duplex low-pressure crude oil filter are at the same horizontal line and separated on both sides of the re oil filter body.
S- indicates that the flange standard of this duplex oil filter is in accordance with gb2501 pn6.
40 means that the working pressure of this low-pressure duplex oil filter is pn0.4 (generally omitted)
40 means the nominal diameter of this duplex crude oil filter is 40mm
Cb/t3594-1994 is an executive standard for domestic ships.

Of course, sometimes we find that the list description written by the customer is: oil filter as40-0.25/0.16 cb/t425. The extra (0.25-0.16) here represents the filtering accuracy of this marine duplex oil filter and duplex low-pressure crude oil filter. According to the standard, the common filtering precision is as follows:

Low pressure crude oil filter, duplex low pressure crude oil filter AS40 0.75/0.26 cb/t425-94
Duplex oil filter, duplex switchable coarse oil filter as4040 0 0.4/0.22 cb/t425-94
Marine low-pressure crude oil filter, marine duplex low-pressure crude oil filter AS40 0.25/0.16 cb/t425-94
Low pressure duplex oil filter, duplex fuel filter AS40 0.18/0.13 cb/t425-94
Straight through low-pressure crude oil filter, straight through duplex low-pressure crude oil filter 0.16/0.09

Through the continuous accumulation of our production experience, our company can produce the following flange sizes for cb/t425 marine low-pressure crude oil filter:
