Changsha Xiangjia Metal Materical Co., Ltd.

The material and steel grade of   high-pressure boiler tubes   have strict requirements. They are designed to work under high temperature and high pressure conditions. A large amount of water vapor will be produced in the high temperature working environment, which can cause corrosion of the steel pipes. That require the steel used in high-pressure boiler tubes to have good corrosion resistance and structural stability. High-pressure boiler tubes are used to make superheater tubes, reheater tubes, air ducts, and main steam pipes for high-pressure and ultra-high-pressure boilers. The low and medium pressure boiler tubes are executed according to national standard 3087, while the high-pressure boiler tubes are executed according to national standard 5310. The outer diameter of the hot-rolled tubes for high-pressure boiler tubes usually ranges from 22mm to 530mm, with varying wall thicknesses of 20mm to 70mm. The outer diameter of the cold-drawn tubes ranges from 10mm to 108mm, ...

High-pressure boiler tubes   are used in a high-temperature and high-pressure environment, so the material selection is strict and its process is similar to the ordinarty seamless pipe. They are widely used as boiler superheater, gas duct, steam pipe, etc. The materials of high-pressure boiler tubes is 20G carbon steel and high-pressure alloy boiler tubes. Corresponding materials can be selected according to the working environments. National standard of boiler tube is GB/T3087-2008 low and medium pressure boiler tubes and GB/T5310-2008 high pressure boiler tubes. Changsha Xiangjia Metal Materical Co., Ltd.  the Steel Pipe Division of ADTO GROUP, is one of the leading manufacturers of steel products in China. We specializes in manufacturing all kinds of steel pipe in various grades and sizes. Years of production experience and manufacturing facilities who have a capacity of 200,000 tons per annual will ensure the good quality and competitive duration of our products.

  High-pressure seamless steel pipe   is a kind of seamless pipe. The manufacturing method is the same as seamless pipes, but there are strict requirements on the steel grades that used to produce steel pipes. According to the operating temperature, it can be divided into two types: ordinary boiler tubes and high-pressure boiler tubes. ①If the service temperature of high-pressure seamless steel pipes is below 450℃. Domestic pipes should be made of No. 10 and No. 20 carbon steel hot-rolled pipes or cold-drawn pipes. ②High-pressure seamless steel pipes are often used in high temperature. The pipes will be oxidized and corroded under the action of high-temperature flue gas and water vapor. The steel pipe is required to have high durable strength, high oxidation and corrosion resistance, and good organizational stability.

High-pressure boiler tubes are a kind of seamless steel pipes. Due to the high temperature working environment will have a large amount of water vapor, then the steel pipes will undergo oxidation and corrosion. That make boiler tubes have good corrosion resistance and organizational stability. GB 5310 high-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air guide tubes, main steam tubes, etc.. The low and medium pressure boiler tube the national standard 3087, and the high pressure boiler tube the national standard 5310. Usually, the hot-rolled tube of high-pressure boiler tube has an exterior range of 22-530mm, and a wall thickness of 20-70mm. The outer diameter of the cold drawn tube is 10-108mm, and the wall thickness ranges from 2--13mm. The steel grades of high-quality carbon structural steel for high-pressure boiler tubes are 20G, 20MnG, and 25MnG. The steel grades of alloy structural steel are 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12Cr...
