15crmoG alloy seamless steel pipe 60 * 4 seamless pipe for high-pressure boiler GB/T5310-2017

Analysis of seamless steel pipes made of 15CrMoG alloy for 60 * 4 high-pressure boilers (GB/T5310-2017)

1、 Material and chemical composition

15CrMoG alloy seamless steel pipe is a low alloy high-strength steel, mainly composed of alloying elements such as chromium (Cr) and molybdenum (Mo). Specifically, the Cr content in the steel pipe is about 15%, and the Mo content is about 0.5%, which gives the steel pipe unique properties. In addition, it also contains a certain amount of carbon (C), although the content is relatively low, it can also improve the strength of the steel to a certain extent.

2、 Performance characteristics

High temperature stability: 15CrMoG alloy seamless steel pipes can maintain good mechanical properties at high temperatures, have high creep strength and persistent strength, and are not prone to plastic deformation or damage.

Corrosion resistance: 15% Cr content gives steel pipes good corrosion resistance in oxidizing media, while 0.5% Mo element enhances the corrosion resistance of steel pipes in reducing media.

High pressure bearing capacity: This steel pipe has high yield strength and tensile strength, which can withstand high pressure and ensure the normal operation of equipment such as boilers and pressure vessels.

Good weldability: Its chemical composition and mechanical properties are stable, easy to weld, and convenient for installation and maintenance.

3、 Purpose

15CrMoG alloy seamless steel pipe 60 * 4 is mainly used for manufacturing heating surfaces, economizers, headers, superheaters, reheaters and other components of high-pressure boilers. Due to its ability to withstand high temperature and pressure working environments and the erosion of corrosive media, it has a wide range of applications in these fields.

4、 Usage environment

This steel pipe is mainly used in high-pressure boilers, which operate under high temperature and high pressure conditions and produce high-temperature flue gas and water vapor, which are prone to oxidation and corrosion. But the excellent performance of 15CrMoG alloy seamless steel pipes enables them to cope with such challenges.

5、 The impact of domestic and international economic environment on high-pressure boiler tubes

Domestic market demand: With the development of the domestic economy, especially the rapid development of industries such as electricity and petrochemicals, the demand for high-pressure boiler tubes is also constantly increasing. This provides a broad market space for the production and application of high-pressure boiler tubes.

Raw material prices: The fluctuations in domestic and international raw material prices have a direct impact on the production cost of high-pressure boiler tubes. If the prices of raw materials increase, production costs will also correspondingly increase, thereby affecting the market competitiveness of the product.

Technological progress: With the continuous advancement of technology, the manufacturing process and performance of high-pressure boiler tubes are also constantly improving. This can not only improve the quality and reliability of products, but also reduce production costs and enhance market competitiveness.

International trade environment: Changes in the international trade environment will also have an impact on the export of high-pressure boiler tubes. If the export market is restricted by trade barriers or other factors, it may affect the export volume and price of products.

In summary, the seamless steel pipe made of 15CrMoG alloy for 60 * 4 high-pressure boilers (GB/T5310-2017) has excellent performance characteristics and broad application prospects. At the same time, the domestic and international economic environment has also had a certain impact on its production and application.
