Secondary stresses, alternating stresses, first over-yielding at operating temperature rise, controlled by the elastic-plastic design stability principle.
The metallurgical industry has its unique industry characteristics and high requirements for oxygen purity. DEAR air separation has cooperated with domestic and foreign metallurgical industry customers in many projects, has rich project experience, and has continuously invested funds to develop energy-saving and intelligent air separation plant. KDON-10000/10000 is highly praised by customers for its high efficiency and stable operation.
DEAR air separation has cooperated with customers in metallurgical industry domestic and abroad in many projects, and has rich project experience. DEAR has continuously invested in the research and development of large-scale air separation plant. In view of metallurgical industry, DEAR combined with the characteristic of this industry, develops high-efficiency energy-saving air separation plant, to meet the needs of large and medium customers. DEAR air separation uses the rapid development of internet technology to establish a remote monitoring system to collect real-time operation data of each air separation plant, and provides the best suggestions for users by using big data analysis.
Approved pressure test specifications and instructions or sketches are available at the test site.
for multi-pressure stage equipment, all manual and automatic valves are checked to be in the correct open/closed position.
all automatic valve operating mechanisms are adequately protected against overpressure.
Pressure tests requiring safety nets, safety shields or other restraints at specified safety distances.

The adsorbent can adsorb and desorb small molecules such as H, N2.CH, C0. C02.02 etc. under operating conditions, but it is difficult to desorb liquid, sulphide and many large molecules such as high hydrocarbons (Cs+), tar, naphthalene, benzene etc. after adsorption. These substances are equivalent to 'toxic substances' for the adsorbent, once the adsorbent is adsorbed the adsorbent will not be able to desorb and regenerate in time, or cannot be completely desorbed, the adsorbent will lose its a...
