Sintered metal tube

Sintered metal tube

The sintered metal tube is a stainless-steel metal mesh filter rolled with multiple layers of perforated metal sintered to form a tube.

You will use the sintered metal tubes for industrial applications such as filtration of gas and liquid in the petroleum and pharmaceutical industry.

What are the Features of Sintered Metal Tube?

Sintered metal tubes have unique features that will boost their performance in different industrial applications.

Here are some of the features of sintered metal tubes that you should identify.

  • Wide variation of filtration rating ranging between 1 micrometer and 250 micrometers or more.
  • Varying sizes which can have smaller internal diameters of up to 10 mm.
  • Great mechanical strength with capability of maintaining better filtration performance under pressure

What Materials are Sintered Metal Tube made of?

You can use different types of materials in the manufacturing process of sintered metal tubes.

One of the materials that you can use is stainless-steel which exhibits very high mechanical strength and corrosion resistance.

Stainless-steel is also capable of working under very high temperatures and pressure without damages.

Apart from stainless-steel, you can also use bronze materials that have great corrosion resistance.

It is also the most cost-effective material that you can use in manufacturing sintered metal tube.

It is, however, quite weak and does not have the great mechanical and tensile strength to support high-pressure applications.

You can also incorporate nickel and its alloys among the materials for manufacturing sintered metal tubes.

It is among the materials that you can use in the production of sintered metal tubes for harsh environments.

Despite the efficiency in harsh conditions, you might have to spend more because they are very expensive.

Which Factors Affect the Cost of the Sintered Metal Tubes?

Apart from that, it has great corrosion resistance properties and mechanical strength that increases durability.

Obviously, an increase in the number and size of sintered metal tubes will increase the cost of the tubes.

How Does a Sintered Metal Tube Work?

Sintered metal tubes

Sintered metal tubes

Depending on the position of the sintered metal tubes in the filtration section, the fluid will pass through the filter.

You should note that the fluid passing through the filter from one end has a lot of contaminants logged in it.

As it passes through the sintered metal tubes, there will be a change in pressure where the pressure will drop.

The drop in pressure simply means lower flowing speed along the sintered metal tube lines.

This increases the time that the fluid takes while passing through the minute pores of the sintered metal tubes.

As that happens, the larger sized contaminants will fail to pass through the pores and allow clean fluid to proceed.

Due to small pore sizes, the contaminants will be trapped pending a momentary backwash that will remove the contaminants.

It will also direct the contaminants to the exit point of the sintered metal tubes thus eliminating them for good.

The clean fluid will also proceed to the fluid exit point for further processing actions.

How do you Manufacture Sintered Metal Tube?

You will manufacture sintered metal tubes through the sintering process.

In this case, the raw materials that you will need are powdered metal or a mixture of different metal alloys.

Here are the main steps that you can follow during the manufacturing process of the sintered metal tubes.

2) Shaping the Materials

After that, you will measure different quantities according to the size of the sintered metal tune that you need.

You will pour the metal powders into a molding machine and then apply enough pressure at room temperature.

High pressure will force the metal powder particles to fuse together and form a solid plate of varying thickness and sizes.

3) Heating Under Furnace

You will proceed to heat the final product below the melting temperatures of the metal.

The heat will force the metal powder particles to bond or fuse together while leaving enough pore spaces.

After that, you will mold the metal sintered metal sheet into several layers which you will roll into a tube.

You must make sure that the ends are properly welded and secured using O-rings to prevent leakages.
