Study on frost crack prevention of rockfill dam with concrete facing in frigid zone;

Causes of frost crack of tubes of graphite cooler and preventive measures

Variety of argon amount in the argon transport system in an oxygen plant resulted in part of liquid argon going into the carbon steel pipelines at the back of the air temperature-type vaporizer and also resulted in frost crack of the carbon steel pipelines.

Because line hardwares are used in the field for fransmission and distribution projects, rainwater, dew and melted snow can infiltrate inside the hardware through micro cracks resulting in frost crack that will seriously affect the normal operation of transmission lines and substations.

In the course of acceptance of construction completion of Dongming 500 kV Switchgear Station,the clamps of large-sectional conduction device were found to have frozen cracks.

The lower reaches of Yellow River is frozen in winter, as a result, a lot of frozen cracks are developed.
