What are the differences in temperature stability between flanged high pressure Y type strainers of different materials?

1. Stainless steel material
Stainless steel is known for its excellent corrosion resistance and high temperature stability, and is an ideal material for manufacturing flanged high pressure Y type strainers. Common stainless steel materials include 304, 316, etc., which can maintain good mechanical properties and chemical stability in both high and low temperature environments.
Temperature range: Stainless steel filters can usually work normally in the temperature range of -20ºC to 180ºC, and some special stainless steel materials (such as 316Ti, 310S, etc.) can even be used at higher temperatures.
Thermal expansion coefficient: The thermal expansion coefficient of stainless steel is moderate, so that the filter is not easy to damage the sealing structure due to thermal expansion at high temperatures.
Mechanical properties: At high temperatures, stainless steel can still maintain high strength and toughness, and is not easy to deform or break.

2. Carbon steel material
Carbon steel flanged high pressure Y type strainers are favored for their low cost and good mechanical properties, but are slightly inferior to stainless steel in temperature stability.
Temperature range: The applicable temperature range of carbon steel Flanged High Pressure Y Type Strainer is relatively narrow, and it is usually used in the range of room temperature to medium temperature to avoid material degradation caused by high temperature.
Thermal expansion coefficient: Carbon steel has a large thermal expansion coefficient, which is easy to cause filter size changes at high temperature, affecting the sealing performance.
Mechanical properties: At high temperatures, the strength and toughness of carbon steel will decrease, so special attention should be paid to its use environment.
3. Cast iron material
Cast iron filters are used in certain specific occasions due to their good casting performance and certain corrosion resistance, but they have limitations in temperature stability.
Temperature range: The applicable temperature range of cast iron Flanged High Pressure Y Type Strainer is limited, and it is usually not suitable for high temperature environments to avoid thermal cracking or deformation of the material.
Thermal expansion coefficient: Cast iron has a large thermal expansion coefficient and is highly sensitive to temperature changes. Special attention should be paid to temperature changes during its installation and use.
Mechanical properties: At high temperatures, the strength and toughness of cast iron will decrease significantly, causing the filter to be easily damaged.
4. Alloy steel material
Alloy steel filters combine the advantages of multiple metal elements, have higher strength and corrosion resistance, and are suitable for high temperature and high pressure environments.
Temperature range: Alloy steel filters have a wide applicable temperature range and can maintain stable performance under high temperature and high pressure environments.
Coefficient of thermal expansion: The thermal expansion coefficient of alloy steel is relatively small, and it has strong adaptability to temperature changes, which is conducive to maintaining the dimensional stability and sealing performance of the filter.
Mechanical properties: At high temperatures, alloy steel can still maintain high strength and toughness, and is not prone to deformation or breakage.

5. Other special materials
In addition to the above common materials, some special materials (such as titanium alloys, nickel-based alloys, etc.) are used to manufacture high-pressure filters to meet the use requirements in extreme environments. These special materials usually have extremely high corrosion resistance, high temperature stability and mechanical properties, but the cost is also relatively high.

6. The impact of temperature stability differences
The difference in temperature stability of flanged high pressure Y type strainers of different materials has an important impact on the performance and service life of the filter. Specifically manifested in the following aspects:
Sealing performance: Filters with poor temperature stability are prone to failure of the sealing structure at high temperatures, causing medium leakage.
Filtration efficiency: Material degradation at high temperatures may cause the filter screen to become clogged or damaged, reducing filtration efficiency.
Service life: Filters that work at high temperatures for a long time are prone to material fatigue and damage, shortening their service life.
