How to correctly select bellows compensators for high-temperature environments?

It is very important to choose a suitable bellows compensator in high-temperature environments, as this can ensure the normal operation and safety of the equipment. Here are some key factors to pay attention to when selecting bellows compensators suitable for high-temperature environments:

Material selection: In high-temperature environments, bellows compensators need to be able to withstand extremely high temperatures and pressures. Therefore, the correct selection of materials is very important. In general, materials commonly used in high-temperature environments include chromium nickel alloy, alloy steel, and stainless steel. These materials have good high-temperature resistance and corrosion resistance.

Bellows structure: The bellows structure of the bellows compensator is also one of the key factors in the selection. In high-temperature environments, the bellows of the bellows compensator needs to have good reliability and stability. Bellows suitable for high-temperature environments should have high strength, toughness, and high-temperature resistance.

Bellows size: The size of the bellows for the bellows compensator should be selected based on actual working conditions. The inner diameter, wall thickness, and thread size of corrugated pipes need to match the requirements of the pipeline system to ensure good sealing performance and reliability.

Interface and connection method: When selecting a bellows compensator suitable for high-temperature environments, it is also necessary to consider its interface and connection method. In high-temperature environments, expansion, contraction, and vibration often occur at the connection, so it is necessary to ensure the reliability of the connection method and be able to adapt to these changes.

Standard compliance: When selecting bellows compensators, it is also necessary to ensure that they comply with relevant standards and regulations, such as domestic GB/T 12777 and international ASME standards. These standards can ensure the quality and reliability of bellows compensators.

Manufacturer's reputation: When selecting bellows compensators suitable for high-temperature environments, manufacturers or suppliers with good reputation and rich experience should be selected. These manufacturers usually have advanced production equipment and technology, and can provide corresponding technical support and after-sales service.

To ensure that the selected bellows compensator can function properly in high-temperature environments, necessary testing and acceptance are also required. These tests usually include strength testing, sealing performance testing, and high-temperature resistance testing of corrugated pipes to ensure that the corrugated pipe compensator meets the design requirements.
