How to choose a stainless steel pressure gauge?

In industrial production, pressure gauges are important tools for measuring and monitoring pressure and are widely used in various industries such as petroleum, chemical industry, metallurgy, electricity, food processing, etc. Especially in some demanding working environments, stainless steel pressure gauges have become the first choice for industrial pressure measurement due to their superior corrosion resistance, high temperature resistance and ruggedness. Choosing a suitable stainless steel pressure gauge can not only ensure measurement accuracy, but also improve the operating efficiency and safety of the equipment.

When choosing a stainless steel pressure gauge, in addition to considering the basic pressure range and accuracy requirements, you should also choose a suitable model according to different installation methods, structural types and use environments. This article will focus on two common stainless steel pressure gauges-bayonet ring stainless steel pressure gauges and crimping ring stainless steel pressure gauges, and discuss their applicable scenarios, advantages and selection criteria in detail to help you make a scientific choice.

Bayonet ring stainless steel pressure gauge

1.What is a bayonet ring stainless steel pressure gauge?
The bayonet ring stainless steel pressure gauge usually adopts a bayonet ring structure design, and the bayonet ring is used to fix the connection between the pressure gauge and the pipeline or equipment. The connection method of the bayonet ring pressure gauge is simple and reliable, and it is mainly sealed and connected with the pipeline interface through the bayonet ring. This design is easy to install and disassemble quickly, and has good sealing.

2.Application of bayonet ring stainless steel pressure gauge
Bayonet ring stainless steel pressure gauges are widely used in industrial environments where the working pressure changes little and require quick installation, disassembly and maintenance. Typical application scenarios include:

General industrial pipelines: suitable for pressure monitoring of various liquid, gas and steam pipelines.
Fluid transportation systems: such as pressure detection in industries such as water treatment and oil transportation.
Small and medium-sized mechanical equipment: such as pressure monitoring of pumps, valves and other equipment.

3.Advantages of bayonet ring stainless steel pressure gauge
Easy installation: The design of the bayonet ring allows the pressure gauge to be quickly connected and disassembled with the pipeline, which is convenient for installation and maintenance.
High sealing: The bayonet ring can provide strong sealing performance, ensuring close contact between the pressure gauge and the medium to avoid leakage.
Strong adaptability: Suitable for most standard pipeline interfaces, with good versatility.

4.Applicable selection
If your working environment requires quick installation, disassembly or frequent maintenance, the bayonet ring stainless steel pressure gauge will be an ideal choice. In addition, its high sealing makes it perform well in medium pressure and general fluid measurement occasions.

Crimped Ring Stainless Steel Pressure Gauge

1.What is a crimped ring stainless steel pressure gauge?
The connection method of the crimped ring stainless steel pressure gauge is different from the bayonet ring. It uses a crimped ring for sealing connection. By applying pressure to the joints of the pipe and the pressure gauge, the two are tightly fixed to form a sealing structure. This method is often used in high-pressure systems or environments that require long-term stable operation.

2.Application of crimped ring stainless steel pressure gauge
The crimped ring stainless steel pressure gauge is mainly used in occasions that require long-term stability and high sealing performance, especially suitable for pressure measurement in high-pressure systems or harsh working environments. Common application scenarios include:

Oil and natural gas pipelines: used for pressure monitoring of high-pressure gas and liquid pipelines.
Chemical and pharmaceutical industries: used for fluid pressure monitoring in harsh environments.
Power system: suitable for pressure measurement of high-pressure liquid media such as steam and hydraulic in power equipment.

3.Advantages of crimped ring stainless steel pressure gauge
High pressure resistance: The crimped ring connection provides extremely high sealing, suitable for high-pressure environments, and can withstand large pressure fluctuations.
Long-term stability: Due to the tighter connection, the crimped ring stainless steel pressure gauge has a longer service life and is suitable for equipment that requires long-term stable operation.
Stronger seismic resistance: In high-pressure environments, the seismic resistance of the crimping ring pressure gauge is usually better, which can effectively reduce the measurement error caused by vibration.

4.Applicable selection
If your application environment involves high pressure, harsh chemical media, or requires long-term stable and reliable pressure monitoring, the crimping ring stainless steel pressure gauge will be a more suitable choice. Especially in some high-temperature and high-pressure situations or where corrosion-resistant materials are required, the crimping ring design provides better sealing and higher safety.

How to choose a suitable stainless steel pressure gauge?
Choosing a suitable stainless steel pressure gauge requires not only considering the structural type of the pressure gauge (such as bayonet ring, crimping ring), but also comprehensively considering the following factors:

1.Working medium and temperature
Different media (gas, liquid, steam) and temperature conditions have different requirements for the material and structure of the pressure gauge. For high-temperature and highly corrosive media, a pressure gauge made of 316 stainless steel will be more suitable.

2.Pressure range
When selecting a pressure gauge, it is necessary to determine the pressure range to be measured. The range of the pressure gauge should be a certain percentage higher than the maximum working pressure to ensure that there will be no error or damage during long-term use.

3.Accuracy requirements
Different industries have different accuracy requirements for pressure gauges. In precision processes, such as chemical, pharmaceutical or food industries, pressure gauges with higher accuracy are usually required.

4.Installation method and space limitations
Choose the appropriate installation method according to the space conditions of the installation environment. If the installation space is relatively small, the bayonet ring pressure gauge is more convenient; if higher sealing and long-term stability are required, the crimping ring pressure gauge is more suitable.

5.Shock resistance and vibration resistance
In a working environment with large vibrations, it is recommended to choose a pressure gauge with liquid filling or a pressure gauge with a crimping ring design, which can better maintain the stability of the measurement.

Choosing a suitable stainless steel pressure gauge requires comprehensive consideration of multiple factors such as the specific working environment, medium, pressure range and accuracy requirements. The bayonet ring stainless steel pressure gauge is suitable for general industrial pipelines and pressure monitoring, and has the characteristics of simple installation and disassembly; while the crimping ring stainless steel pressure gauge is more suitable for high pressure and long-term stable operation environments, and has stronger pressure resistance and sealing. Understanding the structure and application scenarios of these two pressure gauges can help you make a more accurate choice based on actual needs. I hope that the analysis in this article provides you with valuable reference.
