When a pipeline is destabilised by pressure, it is controlled by the critical allowable compressive stress. Buried pipeline destabilisation has two parts, overall and local destabilisation control, due to the variation in pipe diameter.
Metallurgical industry is an industry to develop metal mineral resources and produce various kinds of raw materials for metal products. With the progress of science and technology, the metallurgical industry has new requirements for the process, process, management and application research and development of air separation plant. For many years, DEAR air separation has provided a number of complete solutions for the metallurgical industry, relying on the deep understanding of the industry and excellent product quality to help the efficient development of the metallurgical industry. KDON (Ar) - 12000 / 24000-400, a large scale air separation plant cooperated by DEAR air separation company and customers, has realized the rapid, stable and efficient operation of the production process, which is highly affirmed by customers. It also provides strong technical and product support for customers to cope with the fierce market competition.
Metallurgical industry is an industry that exploits metal mineral resources and produces raw materials of various metal products, which is closely related to the national economy and people's livelihood. At present, Chinese iron and steel industry still has the situation of low concentration, insufficient capacity of high-end products and serious surplus of low-end products. DEAR air separation has provided a number of complete solutions for the metallurgical industry for many years, accumulated rich experience and helped the efficient development of the metallurgical industry. With years of service experience in the metallurgical industry, the small air separation plant KDON (Ar) - 4000 / 4000-110 cooperated by DEAR air separation and customers provides air separation plant with mature technology, stable equipment working condition, excellent performance and energy saving intelligence, which is highly recognized by customers.
The principle and characteristics of large air separation cryogenic nitrogen production
Nitrogen is the main component of air, accounting for about 78% of air. With the progress of science and technology and economic development, the application of nitrogen is expanding and has penetrated into many industrial sectors and daily life.
There are several main methods of producing nitrogen. One of them is cryogenic air separation nitrogen, which is a traditional method of nitrogen production and ha...
Grid frequency or voltage drop
Combined with the compressor machine side voltage meter and electrical system background microcomputer found that during the operation of the compressor grid voltage and frequency are not significantly decreased, the external network power supply system is more stable, so the motor and compressor speed is judged to be a constant value.
Increase in suction temperature at any level
When the suctio...
