Advanced Sintered Metal Tubes Manufacturer in China

Sintered metal tubes are special filtration tubes that are manufactured with stainless steel or other metals and rolled with single or multiple layers of perforated metal to form a tube.

Moreover, these sintered metal tubes have unique features making them reliable and suitable for many industrial applications.

Working Principle:

The working efficiency of the sintered tubes is widely dependent on the positioning of the metal tubes in the unit.

Mainly, they are placed in such a manner that fluid is passed through one to another, leaving a maximum number of contaminants in it.

During the passing of the fluid from the metal tubes, the difference in pressure drop throughout the tubes varies; it usually drops with the flow of liquid.

Subsequently, the decrease in pressure between ends results in the slow flow of liquid, and eventually, more time is required by the tiny pores to complete the process of filtration.

Therefore, the larger-sized dust or contaminants particles fail to pass through the pores, resulting in the more clear liquid coming out from the metal tube.

Furthermore, the small pores hold the dirt particles firmly and release them during the backwashing moment of the system.

This way, the contaminants are eliminated from the tube, leaving behind the clean and clear liquid that can be proceeded for more operations.

Typically, they are used to filtrate liquid and gases in the pharmaceutical and petroleum industries to generate maximum beneficial outcomes.

The uses of sintered metal tubes are widely distributed in various industrial and commercial applications.

It is because sintered tubes can easily be modified and adjusted according to the application requirements.

Moreover, they are broadly associated with applications that require the separation of solids from gases or liquids with a particle size of 1µm-250µm.

Consequently, they offer high filtration levels in equipment that require catalyst protection from dissolving in the fluid and affecting its efficiency.

Some of the main uses of these tubes are described below:

·         Hydroelectric Power Industry

In hydroelectric power generation, the sintered metal tube is utilized for water cleaning resulting in the power generation from the turbines.

Moreover, it helps the turbines to maintain regular and consistent power production with minimum to no interruptions during the process.

·         Petroleum Industries

The sintered metal tubes are helpful in the petroleum industries for the maintenance of various petroleum products and filtration of petroleum products to get rid of contaminants and impurities.

Subsequently, it leaves the petroleum products with a high purity ratio, and thus it does not affect the efficiency of the machines.

·         Other Industrial Uses

Commonly, these metal tubes are broadly used in various industries for high-performance and great filtration efficiencies for gases and liquid filtration processes.

They are used extensively in the following industries:

1. Water Treatment.
2. Polyester Industry.
3. Chemical Industry.
4. Fiber Manufacturing Industry.
5. Pharmaceutical Industry.
6. Gas Filtration Applications.

Figure 2 Sintered Metal Tubes Uses

Yes, sintered metal tubes are anti-corrosive and are manufactured in such a way to bear maximum shock resistance against heat and moisture.

Many industries use metal tubes for filtration requirements in extreme conditions, whether hot or cold, shock vibrations, solvent and corrosion resistance, and other harmful liquids.

Moreover, while using stainless steel grade 316 or 304 for metal tube, it is possible to enhance its corrosion resistance property by implementing the following simple steps:

1.    Frequent Cleaning

Adding frequent cleaning cycles to the porous stainless steel tube, it is possible to enhance its corrosion tolerance and increase its lifespan.

2.    Replace it with Alloy

If you want to make the metal tube more corrosion resistant, replacing its main structure with a superalloy is better.

This alloy can be made with the combination to resist the maximum corrosion resistance without affecting the efficiency of the entire unit.

3.    Use Polymeric Filter

Using a polymeric filter is also a suitable option to enhance the corrosion resistance in the sintered metal tubes.

However, it is not a good option under high pressures, elevated temperature range, or extreme exposure to vibration or shock.

4.    Coating

Coating a filtering material with an effective silicone solution will enhance its corrosion resistance property making it less prone to temperature changes.

Furthermore, it will also increase the efficiency and durability of the filter tube.

Materials used to manufacture sintered metal tubes may vary depending on the conditions the filter will be exposed to and its required application.

Typically, the following materials are used for the production of premium quality and high performance sintered metal tubes:

1.    Stainless Steel

The commonly used material for the manufacturing of metal tubes is stainless steel, usually grades 304 and 316L are used.

They are used due to their high strength, mechanical nature, and greater corrosion resistance property.

Moreover, porous stainless steel tubes provide high pressure and temperature resistance, making them less prone to potential damage.

2.    Bronze

Another extensively used material for metal tubes is bronze. It is used for its high corrosion resistance property under various moist applications.

Moreover, the bronze tube is the most pocket-friendly material that can be used to manufacture sintered metal tubes.

However, it possesses weak strength, machinability, and less tolerance under high pressure, limiting its use to fewer applications.

3.    Nickel and its Alloys

Among all the materials, nickel and its alloys can also be used for the production of pre-eminent quality and highly efficient sintered tubes.

These can be used to manufacture tubes under harsh conditions, but the user has to spend more on them as they possess the ideal resistance properties of tubes.

Sintered metal tubes are manufactured with single or multi-layers using a sintering process depending on the application requirements.

In the manufacturing process of these tubes, powdered metal or a combination of different metals are used to obtain desired properties in the product.

Typically, the following main steps are used in the production of sintered tubes:

Step 1: Raw Material Preparation

The first step is to prepare the raw material to metal powder particles for further processing in the form of a sintered tube.

Normally, the material can be prepared by atomization or grinding it to form a fine powdered structure.

Depending on the type of product to be formed, pure metals or a mixture of alloys can be used for effective outcomes.

Step 2: Shaping

Once the material is ready for processing, it is time to give the material desired shape and size as you wish to see in your product.

Mix the quantities of powder according to the amount of tube you want and pour it into the molding machine for further processing.

Then, high pressure is applied to the mold at room temperature to let the powder metal particles fuse together and solidify according to the shape of the mold.

Step 3: Applying Heat

Once they are completely compressed and adopted the shape of the mold, the metal is taken out from the mold for heating.

The metal is then placed on a furnace to apply temperature under its melting point.

Here, the heat helps the metal particle fuse while leaving pore sizes for the filtration process.

Step:4 Rolling the Metal

When the heating is completely done, the sintered metal sheet is rolled several times to form single or multiple layers tubes.

Then, tubes are secured and welded with the help of the O-rings to prevent any leakage during the filtration process and hold the solid particles.
