A few days ago, Zhanyi Fire was invited to carry out fire safety training for the Yunling Workers' Qualities Construction Project for migrant workers to train Qujing Demonstration Class to further improve the fire safety safety of migrant workers.
The lecturers combined most of the migrant workers with low level of education, the actuality of legal awareness and lack of fire safety knowledge, using slides to explain and video playback typical heavy fire cases that occurred throughout the country in recent years. Explained the importance of fire hazards, the need to prevent fires, and the importance of eliminating potential fire hazards. Combined with the reality of migrant workers, the paper explained knowledge of fire laws and regulations, home fire prevention, and fire prevention at building sites. Detailed analysis of the causes, causes, and responsibilities of the fire at the construction site, as well as the huge losses incurred by the fire to the unit and the individual, and the attention to the conditions of the fire, the hazards of the fire, how to prevent fires, and the use of electricity for household fires The basic firefighting knowledge such as matters, fire escapes, and escapes were explained in detail for migrant workers.
“Before only working to earn money, which control what fire safety, through training, so that we feel like buying a Ping An Insurance ... ...†said a migrant worker.
Through this training, migrant workers have expressed that this fire safety training has benefited greatly. After returning, they must implement the learned fire theory, skills, and fire safety knowledge into their daily practical work, in order to maintain the county's sustained and stable fire contribution. Your own strength.
DUPLEX STAINLESS STEEL
Duplex Stainless Steels Available

Duplex Stainless Steel Overview
Duplex Stainless Steels, also referred to as austenitic-ferritic stainless steels, are a family of grades with about equal proportions of ferrite and austenite. These steels have a duplex microstructure which contributes to their high strength and high resistance to stress corrosion cracking. Due to their high content of chromium, nitrogen and molybdenum, duplex steels offer good resistance to local and uniform corrosion. Duplex stainless steels have good weldability.
Today, modern duplex stainless steels can be divided into three groups:
Lean Duplex such as LDX2101
Standard Duplex such as 2205, the work-horse grade accounting for more than 80% of duplex usage
Super Duplex such as Ferralium 255 and Zeron 100 and LDX2507
Of the duplex grades, duplex 2205 is the most widely used. However, the super duplex steels like Zeron® 100 and LDX2507 are excellent for servicing severe corrosive environments, such as offshore and marine applications. Lean duplex 2101 is available as an economic alternative to 300 series stainless steels.
