Boiler Thermal Expansion Displacement Indicator is a dedicated mechanical measuring instrument for boiler and high-temperature piping systems.It visually detects the thermal expansion and three-dimensional displacement of steam drums,headers,main steam pipes and other critical components during heating,steady operation and cooling down.
By reading real-time displacement data,operators can confirm if thermal deformation stays within design limits.It effectively avoids pipe distortion,weld fracture,stress overload and medium leakage resulting from blocked or abnormal expansion,serving as an essential safety part for boiler units.
Structure
Fixed support&base:High-strength steel structure,mounted on stationary boiler frames as a stable reference point
Precision dial and pointer assembly:Standard millimeter scales for clear,direct reading
Connecting rod&universal joint:Flexible connection with low friction,adapting to multi-directional movement and guaranteeing measuring accuracy
Heat-resistant components:Made of high-temperature alloy,suitable for long-term service in harsh boiler environments
Working Principle
Reset all pointers to zero for cold state calibration before boiler startup.
When the system is heated,boiler components expand and generate displacement in multiple directions.
The connecting rod drives the pointers to move synchronously to indicate actual displacement values.
Timely inspection and adjustment will be carried out once readings exceed the permitted range.
Key Features
Pure mechanical design,no power required,stable and reliable performance
Excellent high temperature and vibration resistance,long service life
High measuring precision,simple structure and low maintenance cost
Easy on-site installation and intuitive data observation
Application
Mainly used in thermal power plants,industrial high-pressure boilers,petrochemical and central heating projects.It is widely equipped on large-diameter high-temperature steam pipelines,headers and steam drums.
