Pipe Hangers & SupportsPipe Hangers & Supports
Pipe Hangers & Supports refer to the devices installed to support or protect the piping system in power plants,
petrochemical complexes, LNG terminals, and offshore plants. They allow for displacement due to the weight
and thermal expansion of the pipes, and they support or protect the piping system from fluid vibrations,
earthquakes, and external shocks. All Pipe Hangers & Supports are independently developed by SEONGHWA.

Product Introduction
Constant HangersDevices that support static loads while fully absorbing the thermal displacement of the piping systems.
Designed to maintain moment equilibrium regardless of
changes in the compression of the spring inside the product
due to thermal displacement of the piping, they are characterized
by maintaining a constant load.
These products are used in piping systems
where thermal displacement is significant,
or where changes in stress on the piping or equipment are sensitive.
In other words, they absorb shocks in the direction of
pipe movement while maintaining the load consistently.
Variable HangersDevices that support static loads while partially absorbing the thermal displacement of the piping systems.
As the thermal displacement of the piping changes, so does the
compression of the spring and the load it supports changes.
These products are used in piping systems where thermal displacement is
relatively small, or where changes in stress on the piping or equipment
are not sensitive. Like constant hangers, they absorb shocks
in the direction of pipe movement, but the load on the product changes.
SnubbersDevices that support dynamic loads and fully absorb the thermal displacement of the piping systems.
It features a stable hydraulic system with a precise valve mechanism
that operates similarly to a car's seatbelt: unresponsive to certain levels
of shock or change, but activating outside of those parameters.
Pipe ClampsA type of pipe support device that surrounds pipes to restrict their movement.
It covers the outside of the pipe and transfers the load generated from the piping to another location.
They are manufactured in various forms depending on load, temperature, and shape conditions.
Other Accessories
Thread products, rod products, etc. required when installing pipe supports to pipes and structures.
Products suitable for the installation environment are selected to securely connect piping and structures.
Cryogenic Pipe Hangers & SupportsPipe Hangers & Supports applied to the cryogenic piping of liquefied natural gas, liquefied petroleum gas, and chemical plants.
It is a device that perfectly insulates against heat from the outside,
using HD-PUF (High-Density Polyurethane Foam) and cryogenic adhesive.
