Selection Guide for Y-type Strainer Made of Nickel Aluminum Bronze B148 (C95800) Material Under High Temperature Working Conditions

In industrial production, high temperature working conditions impose extremely stringent requirements on the performance of equipment. Especially in the filtration process involving high-temperature fluids, it is crucial to choose the appropriate filter material and model. Y-type strainer made of nickel aluminum bronze B148 (C95800) material have become the first choice for many engineers due to their excellent high temperature resistance and corrosion resistance. This article will analyze in detail how to select Y-type strainer made of nickel aluminum BRONZE B148 (C95800) material under high temperature working conditions to help you make informed decisions.

I. ADVANTAGES OF NICKEL ALUMINUM BRONZE B148 (C95800) MATERIAL

Nickel aluminum BRONZE B148 (C95800) is a high-performance copper alloy, and its main components include copper, aluminum, nickel, iron, etc. This material has the following remarkable characteristics:

• Excellent Corrosion Resistance: Nickel aluminum bronze exhibits outstanding corrosion resistance in seawater, acidic environments, and various chemical media, and can effectively resist the erosion of corrosive substances.

• High Strength and Toughness: The alloy has high strength and good toughness, and can maintain structural stability under high pressure and high temperature environments.

• Good Thermal Stability: Under high temperature working conditions, nickel aluminum BRONZE B148 (C95800) can maintain its physical properties and is not prone to deformation or degradation.

• Anti-foling by Marine Organisms: It is particularly suitable for offshore engineering and seawater desalination fields, and can effectively prevent the attachment of marine organisms.

II. KEY POINTS FOR SELECTING Y-TYPE STRAINER UNDER HIGH TEMPERATURE WORKING CONDITIONS

(1) Operating Temperature Range
Y-TYPE STRAINER made of nickel aluminum BRONZE B148 (C95800) material can withstand a relatively wide operating temperature range, usually between -20 °C and 300 °C. Under high temperature working conditions, it is crucial to ensure that the operating temperature of the filter does not exceed the tolerance limit of its material. For example, in the oil refining process, if the medium temperature approaches or exceeds 300 °C, special attention needs to be paid to the thermal stability of the material.

(2) Selection of Nominal Pressure
Select an appropriate nominal pressure grade according to the working pressure of the system. The nominal pressure range of nickel aluminum BRONZE Y-TYPE STRAINER is usually from 1.6 MPa to 10 MPa. Under high temperature working conditions, pressure fluctuations may be more frequent and severe, so it is recommended to choose a filter with a pressure grade one level higher than the maximum working pressure of the system to ensure safety and reliability.

(3) Filtration Accuracy
The selection of filtration accuracy depends on the particle size of impurities in the fluid and process requirements. The filtration accuracy range of nickel aluminum BRONZE Y-TYPE STRAINER is generally from 10 mesh to 300 mesh. Under high temperature working conditions, since the viscosity of the fluid may change, the filtration accuracy needs to be adjusted according to the actual working conditions. For example, in the filtration of high-temperature oil products, it may be necessary to choose a filter screen with higher accuracy to remove finer impurity particles.

(4) Inlet and Outlet Diameters
In principle, the inlet and outlet diameters of the filter should not be smaller than the inlet diameter of the corresponding pump, and are generally consistent with the diameter of the inlet pipeline. Under high temperature working conditions, due to the increase in the expansion coefficient of the fluid, which may lead to changes in the flow rate, it is necessary to ensure that the diameter of the filter can meet the design flow rate requirements of the system.

(5) Connection Methods
Common connection methods include flange connection, threaded connection, etc. Under high temperature working conditions, flange connection is more reliable because it can provide better sealing performance and prevent the leakage of high-temperature media. Meanwhile, choosing flange sizes and pressure grades that comply with international standards (such as ANSI, DIN, etc.) can ensure the compatibility of the filter with the pipeline system.

III. Comparison Between Nickel Aluminum Bronze B148 (C95800) and Other Materials

(1) Comparison with Stainless Steel Material
Stainless steel is another commonly used filter material with good corrosion resistance and strength. However, under high temperature working conditions, the performance of stainless steel may be somewhat limited. For example, stainless steel is prone to oxidation and intergranular corrosion in high temperature environments. In contrast, nickel aluminum bronze B148 (C95800) has better antioxidant and corrosion resistance properties at high temperatures and can better adapt to high temperature working conditions.

(2) Comparison with Carbon Steel Material
Carbon steel strainer have a lower cost, but they are significantly inferior to nickel aluminum BRONZE B148 (C95800) in terms of corrosion resistance and high temperature resistance. Carbon steel is prone to corrosion and oxidation in high temperature and corrosive media, resulting in a shortened equipment life. Nickel aluminum bronze B148 (C95800), on the other hand, can maintain long-term stable operation in high temperature and corrosive environments. Although its initial cost is higher, in the long run, its maintenance cost and replacement frequency are lower.

IV. ANALYSIS OF APPLICATION CASES

(1) Petrochemical Industry
In petrochemical production, high temperature, high pressure, and corrosive media are common working conditions. For example, in a catalytic cracking unit, it is necessary to filter high-temperature oil and gas to remove catalyst particles and other impurities. Y-type strainer made of nickel aluminum BRONZE B148 (C95800) material can effectively protect downstream equipment from damage caused by impurities due to their excellent high temperature resistance and corrosion resistance.

(2) Offshore Engineering Field
The marine environment has extremely high requirements for the corrosion resistance of equipment. In seawater desalination systems, Y-type strainer made of nickel aluminum BRONZE B148 (C95800) material are widely used in the seawater pretreatment process. Their ability to resist seawater corrosion and the attachment of marine organisms can ensure that the strainer maintain good filtering effects during long-term operation while reducing maintenance costs.

V. MAINTENANCE AND CARE RECOMMENDATIONS

(1) Regular Cleaning
Regular cleaning of the filter screen is the key to maintaining the performance of the filter. Under high temperature working conditions, impurities may form scale on the filter screen, affecting the filtering effect. It is recommended to formulate a cleaning plan according to the actual working conditions, such as cleaning once a month or once a quarter.

(2) Inspection of Seals
Changes in high temperature and pressure may cause seals to age or be damaged. Regularly checking the integrity of seals and promptly replacing damaged seals can effectively prevent media leakage.

(3) Monitoring of Operating Temperature and Pressure
Install temperature and pressure sensors to monitor the working status of the filter in real time. If abnormal increases in temperature or pressure are detected, measures should be taken in a timely manner to avoid equipment damage.

VI. SUMMARY

Under high temperature working conditions, it is crucial to choose the appropriate Y-TYPE STRAINER material and model. Y-TYPE STRAINER made of nickel aluminum bronze B148 (C95800) material have become an ideal choice due to their excellent high temperature resistance and corrosion resistance.
