High-temperature metal compensator

High-temperature metal compensators can compensate for the deformation of pipelines caused by temperature changes or mechanical displacements. When the operating condition temperature is relatively high, the compensator of ordinary specifications cannot operate stably in a high-temperature environment.

High-temperature metal compensators, also known as high-temperature metal expansion joints, can compensate for the axial deformation of pipelines caused by temperature changes or mechanical displacements. When the operating condition temperature is relatively high, the compensator of ordinary specifications cannot operate stably in a high-temperature environment. It can withstand high-temperature environments while compensating for displacement, reducing vibration and noise.

Metal compensators can withstand high-temperature operating conditions by casting furnace charge with built-in rake nails, using temperature-adapted plates, and installing an internal heat insulation layer after diameter reduction.

1. Built-in rake nails for casting furnace charge

When the medium temperature is relatively high, it is necessary to cast the furnace charge to enable the metal compensator to withstand high-temperature environments. Palladium nails are added inside the compensator to fix the casting charge. The palladium nails, composed of galvanized screws, nylon tubes and fixed original sheets, etc., are selected in shape according to the thickness of the insulation layer, and their length is related to the thickness of the casting furnace charge. If the charge is thin, the length is short; if the charge is thick, the length is long.

Second, use temperature-adapted plates

The base material is stainless steel. Due to the different applicable temperatures and characteristics of various materials, the suitable material can be selected according to the usage temperature.

1. The reducer is equipped with an internal heat insulation and heat preservation layer

The diameter of the metal compensator structure is reduced, and the appropriate heat insulation packing layer is selected based on the medium temperature and properties. The heat insulation filler layer is built in by changing the diameter. Enable the compensator to operate stably under high-temperature working conditions.

When choosing high-temperature metal compensators, the appropriate specifications and models should be selected based on the specific working environment and requirements of the pipeline system.
