High-pressure boiler tube price market and production method use
Edit:Shenyang Sidi Ou Trading Co., Ltd.   UpDate:2018-08-15

The high pressure boiler tube is a type of boiler tube and belongs to the category of seamless steel tubes. The manufacturing method is the same as that of a seamless tube high pressure boiler tube, but has strict requirements on the steel grade used for the manufacture of the steel tube. High pressure boiler tubes are often used in high temperature and high pressure conditions. High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air guiding tubes, main steam tubes, etc. for high-pressure and ultra-high pressure boilers.

Recently, the domestic high-pressure boiler tube market price has dropped slightly. According to the monitoring data of the Lange Steel Cloud Platform, the average price of 1.0mm galvanized sheet in ten key cities is 5111 (ton price), which is 12 yuan lower than the previous working day. The average price of 0.47 mm color coated sheets in key cities was 5,789 yuan (ton price), which was 37 yuan lower than the previous working day.

The price of high-pressure boiler tubes in the futures market rose at the end of the day, iron ore and coking coal rose by more than 3%, and coke, hot coil and Zheng coal rose by nearly 1%. The overall spot market price was weak, and the market price of coated plates decreased slightly. The galvanized resources of private steel plants are about 4,620 yuan in Tianjin Fengming market. Market transactions: In recent days, there have been many rains and snows, the snow in the steel market has become increasingly fierce, the transaction has weakened again, and the enthusiasm for downstream procurement has fallen sharply.

Overall, the recent decline in the board, the weakness of the futures market is difficult to change, demand continues to be weak, businesses are pessimistic, there is no winter hoarding intention, the market is running weak, it is expected that the domestic coated sheet market price will be weak in the short term.

High-pressure boiler tube production method and use

Manufacturing method: 1 boiler tube is generally used at temperatures below 450. Domestic tubes are mainly made of hot-rolled or cold-drawn tubes of carbon steels of No. 10 and No. 20. 2 High pressure boiler tubes are often exposed to oxidation and corrosion under the action of high temperature flue gas and water vapor. Steel pipes have high durability, high oxidation resistance and corrosion resistance, and good microstructure stability.

Uses: 1 boiler tube is mainly used to manufacture water wall tube, boiling tube, superheated steam tube, superheated steam tube for locomotive boiler, large and small smoke tube, arch brick tube and so on. 2 High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, guide tubes and main steam tubes for high-pressure, ultra-high-pressure boilers.
