Gauge bends (also known as buffer, condenser, or siphons) are
primarily used in pressure gauge applications to protect the gauge
from media shocks and high temperatures, thereby extending its
service life and ensuring accurate measurements. Its main
applications include:
Buffer impact: when the measured medium has instantaneous pressure
fluctuation or impact, the meter bend can absorb and disperse these
impact forces through its bending shape and the "water column" or
"steam condensate" formed by the medium in the pipe to avoid direct
damage to the internal mechanical structure or sensor of the
pressure gauge.
Reduce the medium temperature: for high-temperature medium (such as
steam), the gauge bend will condense it before entering the
pressure gauge, forming a layer of water or isolating liquid,
reducing the medium temperature entering the pressure gauge and
preventing the superheated medium from damaging the pressure gauge.
Equipment safety protection: through buffering and cooling, the
gauge bend can effectively protect the pressure gauge from failure
due to improper medium, so as to avoid huge losses and safety
hazards caused by pressure gauge failure.
Applicable to various media and scenarios: meter elbow is
applicable to measuring high-temperature steam, condensable hot gas
and other media that may cause transient impact. For example, the
application of meter bend can be seen in the fire pump outlet pipe,
oil pipe, thermal pipe network and other systems
