Product Introduction
Spring supports and hangers are elastic devices used for supporting pipelines, equipment or steel structures. They are mainly used to bear vertical loads and also allow for axial or lateral displacements caused by thermal expansion and contraction, vibration or displacement. Its core function is to balance the system load, reduce stress concentration, and absorb additional forces generated by vibration or displacement. It is widely used in industrial fields such as petroleum, chemical engineering, power, and metallurgy.
Main types
Variable spring support hanger (variable spring)
Features: The spring stiffness varies with the load and allows for relatively large displacements.
Application: It is suitable for pipelines with large thermal displacement (such as high-temperature steam pipelines).
Category
TD type (Upper thread suspension type)
TH type (Single-ear suspension type)
TS Type (Double-ear Suspension Type)
Constant force spring support and hanger (constant force spring)
Features: It provides an approximately constant supporting force, and the force value changes very little during displacement (usually ≤5%).
Application: It is used for critical pipelines that are sensitive to loads or have large displacement (such as main steam pipelines in nuclear power plants and thermal power plants).
Rigid spring support hangers
Features: High rigidity, small displacement, used for fixed support or displacement limitation.
Core components
Spring element: It provides elastic support and is mostly made of alloy steel (such as 60Si2MnA).
Load adjustment device: Adjust the pre-compression amount to match the design load.
Displacement indicator: Displays the displacement status of the spring, facilitating installation and maintenance.
Connecting parts: including hangers, bolts, hinges, etc., are used to connect with pipes or structures.
Key points for selection
Load calculation: including working load, installation load and possible impact load.
Displacement: Select the type of spring (variable or constant force) based on the thermal displacement of the pipeline.
Environmental factors: Consider temperature and corrosiveness (anti-corrosion coating or special materials are required).
Installation space: Determine the form of supports and hangers (suspended type, supported type or parallel type).
Installation and Maintenance
Installation requirements
Install at the designed position and with the pre-compression amount to ensure even load distribution.
Check that the displacement indicator is in the cold position.
