Seamless pipe material
1. Carbon steel seamless pipe: It is the most common material, mainly composed of carbon and a small amount of chromium, molybdenum, manganese and other elements. It has a wide range of applications and is suitable for low-pressure fluid transportation.
2. Alloy steel seamless pipe: It is heated by round steel containing a variety of alloy elements. It has a wide range of applications such as corrosion resistance, high temperature and high pressure, and is mainly used in aviation, aerospace, metallurgy and other industries.
3. Stainless steel seamless pipe: It has excellent corrosion resistance and is suitable for use with high-temperature and high-pressure equipment, such as boilers, petrochemicals and other industries.
4. Aluminum alloy seamless pipe: low density, good thermal conductivity, high mechanical strength, widely used in various types of aircraft.
To put it simply, low-alloy seamless pipe is actually a stainless steel plate made of aluminum alloy. It is a long steel plate with a hollow cross-section and no seams around it. Low-alloy seamless pipe is made of ordinary carbon seamless pipe. On the basis of steel pipe, the content of Mn is increased. In the past, it was also called 16mn seamless steel pipe. The increase in alloy chemical elements can improve the tensile strength of low alloy seamless pipes. It can withstand low temperature stamping of minus 40 degrees Celsius and is suitable for use in some special geological drilling and low temperature resistant fields. What it mainly represents is the difference in impact temperature. This material is a relatively basic material and a low alloy material with a very high usage rate. Nowadays, there are many categories of seamless steel pipes on the market. In the process of steel pipe processing, the requirements are very strict and relatively complicated and cumbersome.
Comprehensive performance characteristics of low alloy seamless pipes
The comprehensive performance of low-alloy seamless pipes is very good. Whether it is plastic welding or welding, it is very good. Seamless steel pipes have good low-temperature flexibility and are suitable for use in cold environment structures below minus 40 degrees. In addition, its cold and hot processing performance and rust and corrosion resistance are very good, and its weldability and comprehensive mechanical properties are also relatively good, so it is often used in pressure vessels, bridge power station equipment, lifting and transportation machinery, etc. with higher load levels. High welded construction.
Applications of low alloy seamless pipes
The scenes and environments used by various seamless pipes are also different. Seamless steel pipes for structural use are generally more suitable for structures and machinery. Seamless steel pipes for fluid transportation are commonly used to transport fluids such as water, oil, gasoline, etc. Steel pipes are special steel pipes because they are used in fluids and must have certain anti-corrosion capabilities. Low-pressure heating seamless steel pipes are used to make various high-pressure heating furnace pipes and boiling water pipes. High-pressure boiler pipes are used to make high-pressure water pipes. The working ability of this type of steel pipe must be very strong.
