Stainless steel Cuno filter housing

Which Types of Stainless Steel are used to make Cuno Filter Housing?

We already know that stainless steel is the ultimate choice of constructing the filter housings.

Besides, the construction of Cuno filter housing utilizes either the 304 stainless steel or 316 stainless steel.

However, though the two types of material are suitable for housing, you should note that they all have distinct chemical compositions and features.

Compositions of SS304 v. SS 316.

The structures of the two grades of stainless steel incorporate both chromium and nickel.

Nevertheless, SS 304 has a chemical composition of 18 % chromium and 8 % nickel.

Whereas, SS 316 consists of nickel 10%, Molybdenum 2%, and chromium 16%.

Notably, the additional molybdenum component makes the SS 316 highly resistant to aggressive chemicals such as phosphoric acid, sulphuric acid, acetic acid, etc.

Functionality and practicability of the SS 304 v. SS 316

Stainless steel filter housing

· SS 304

Even though SS 304 chemical composition exempts Molybdenum, it is still resistant to oxidation and corrosion to some extent.

Thus the SS 304 material still works optimally in oxygen concentrations and at extreme temperatures.

Besides, you can swiftly fabricate them to have an attractive surface finishing.

The various applications of SS 304 include the manufacturing of tanks, pressure valves and vessels, tubing, filter housing, and piping.

· SS 316

SS 316 has excellent corrosion resistance to several harsh chemicals aside from being heat resistant.

This feature is due to the extra molybdenum component in its structure.

And that is what gives the SS 316 mileage over the SS 304 material.

Therefore, the SS 316 material forms the number one priority material in the pharmaceutical industry since it minimizes potential metallic stain.

Besides, even at high temperatures of aggressive liquids, the material still maintains its considerable resistance.

Again, the material is durable, easy to fabricate, clean, improve the grit finishing, and also weld.

The stainless steel materials are economically efficient construction materials in the filter housings.

You will not have to worry anymore about the frequent “eating up” of your filter housing and constant replacements.

All these may economically impact your business due to downtime and extra unplanned expenses.

What is the Working Principle of Cuno Filter Housing?

Remember, the filter housing encloses the interior segments of the filter systems.

Generally, the working principle of housing is quite straightforward.

The component to be filtered enters the filter housing via the inlet.

It then uniformly distributes around the cartridge.

After filtration, the clean fluid exits through the outlet.

Aside from getting trapped into the cartridge, the contaminants may also adhere to the interior of the filter housing.

What are the Available Types of Cuno Filter Housing?

Cuno filter housings come in a wide range of shapes and designs dependent on the form of application.

Below is a brief description of the available types:

· Bag Filter Housing

Bag filter housing, also commonly known as bag filter vessel, come in two major forms, i.e., single bag filter housing or multi-bag filter housing.

Bag filter housing corresponds to the bag filter systems, which in turn large capacity of holding dirt.

During the changeover of parts, the filter housings easily and quickly open and closes.

The housing has an excellently positioned drainage compartment on both the inlet and bottom outlet side.

To maintain non-contaminated free-flowing fluid, you can use a multi-bag filter housing.

The multi-bag filter housing encloses several bag filters, thereby providing economically bulky filtration.

Such kind of housing has got design pressures of maximum 150psig, featured vent, and connected pressure gauges.

Some of the desirable features of the bag filter housing include:

  • Accommodation of high flow rates of fluids while withstanding a pressure of a maximum of 1.5 Mega pascals.
  • The sealing type is of positive o-ring, which enhances secure and easy operation.
  • It Facilitates quick filter element changeover.
  • Has heightened housing capacity, which reduces the fluid energy losses.
  • Polished mirror grit surface to restrict adherence of dirt on the surface.

· Industrial Filter Housing

The industrial filter housing is available in selected varieties.

However, the major types include sanitary filter housing, lenticular filter housing, and sock filter housing.

i. Sanitary filter housing; this type is mostly applicable in applications which demand high precision of purity such as pharmaceutical, food, and beverage industries.

Moreover, they come in potentially five distinct connections such as SMS male, welded, DIN, tri-clover, and macon.

The design is cGMP compliant and features several control auxiliaries including manometers, sterile port, sight glass, etc.

ii. Lenticular Filter housing; this is an upright positioned housing design.

The vertical posture is essential in avoiding surface adherence of contaminants, consuming little space in comparison to typical plate filters.

Above all, the housing can serve you long since its means of washing is simply by backflushing and re-using.

Pressure gauges, vent valve, drain valves, etc. are some of the auxiliary components of this type of housing.

iii. Sock Filter Housing; though they are of several designs, they all look like the bag filter housing designs.

A typical example includes the ones attached to the filter bags.

The design thus enables the bag filter to operate with different levels of rates of fluid flow.

· Cartridge Filter Housing

This time is compatible with the proficient filtration of gases and liquids.

It also does sterilization and clarification.

In such filter systems, the cartridge extracts the contaminants and eliminates them through the outlet valve.

They also come in several varieties of pressure rating, dirt accommodation capacity, and rates of flow.

The cartridge filter housing has got properly fitted T-port/ in-line, open/L-port.

Apart from the standard fittings, the multi-cartridge filter housings must have threaded or flange connections.

· Duplex Filter Housing

The duplex filter housing assures constant, steady, and robust filtration operations not withstanding the piping techniques in place.

The design features dual stainless steel filter housings fitted with a three-mode changeover valve in between the housings.

Such design offers a high level of flexibility since you can easily shift your operations between the housings even if one breaks down or needs sanitation.

The notable features of the duplex filter housing include: interconnected duplex filters, easily available covers, compact housing, and spring fitted covers.

· In-line Filter Housing

In-line filter housings are suitable for use in oil and gas application system filters.

Most importantly, they are often used as process filters to protect other vital components from contamination.

These parts may include pumps, hydraulic circuits, and pressure reducers.

Consequently, you should fix the entire in-line filter system up the system pump to protect the fragile parts of the pump.

A few of the interesting features of the in-line filter housings include support core, bypass valve, electrical indicator, venting and draining connections, bolted cover plates.
