Alloy Steel Pipe
Alloy Steel Pipe is a kind of seamless steel pipe. Because alloy steel pipe contains more Cr element, so that the alloy pipe has better performance the general seamless steel pipe, such as high temperature resistance, low temperature resistance, and corrosion resistance.

Standard: ASME SA213, SA335; ASTE A202, A213, A335, A519, A333

Main material: 20MnG, 25MnG,15CrMoG, 35crmo, 42crmo, 12Cr2MoG, 12Cr1MoVG, 12Cr2MoWVTiB, 10Cr9Mo1VNb, 10crmoal, 9cr5mo, 9cr18mo, SA210A1, SA210C, SA213 T11, SA213 T12, SA213 T22, SA213 T23, SA213 T91, SA213 T92, ST45.8/Ⅲ,15Mo3, 13CrMo44, 10CrMo910

The Advantages Of Alloy Steel Pipe
With the continuous development, alloy steel pipe is applied to the more and more field, whether it is in the water, oil or gas and other fields, alloy steel pipe prospects is very broad, here in this article we will discuss the comparative advantage of alloy steel pipes.
When other elements comprising metals and non-metals are added to carbon steel, alloy steel is formed. These alloy steels display various environmental, chemical and physical properties that can vary with the elements used to alloy. Here the proportion of alloying elements can provide different mechanical properties. Alloy steels contain alloying elements (e.g. manganese, silicon, nickel, titanium, copper, chromium, and aluminum) in varying proportions in order to manipulate the steel’s properties, such as its hardenability, corrosion resistance, strength, formability, weldability or ductility. The main applications of alloy steel pipe are a power station, nuclear power plant, high-pressure boiler, high temperature superheated and re-heater coil, etc. of high-temperature pipeline and equipment.
The alloy steel pipe adopts high quality carbon steel, alloy structural steel and stainless & heat resisting steel as raw material through hot rolling or cold drawn to be made.

With the continuous development of society, alloy steel pipe is applied to the more and more field, whether it is in the water, oil or gas and other fields are applied to the alloy steel pipe, alloy steel pipe prospects is very broad, what is the comparative advantage compared to other steel pipes? Here to understand the advantages of alloy steel pipe.
Environmental protection has been the theme of social development of all walks of life, the biggest advantage is to achieve 100% recovery, which compared with other steel is naturally superior, will not cause material waste.
Wide application scope, it is widely used in petroleum, gas and other industries, for this important energy, the requirements of the pipeline is also very strict, in the power plant, nuclear power, high pressure boilers and other industries have also been widely used.
Save easily. General steel pipe material is easy to rust in the air for a long time, but the alloy steel pipe use the most advanced material, the anti-oxidation also has great achievements, not easy to rust, use a longer time.
Advantages of Alloy Steel Pipes
High Strength
Some alloy steels like chrome moly pipe because of the chemical makeup of Molybdenum (Mo) and Chromium (Cr). Molybdenum increases the strength of steel as well as the elastic limit, resistance to wear, impact qualities, and hardenability. Chrome raises the tensile strength, yield, and hardness. The composition chrome moly alloy steel pipe make it ideal for use in power plants, refineries, petro chemical plants, and oil field services where fluids and gases are transported at extremely high temperatures and pressures.
Corrosion Resistance
When metals encounter oxygen, they can undergo oxidation reactions. This, in turn, causes corrosion.
Chromium (or chrome), is virtually irreplaceable in resisting oxidation at elevated temperatures, making Alloy Steels more resistant to corrosion than most metals. This allows them to maintain their integrity for longer than other metals, especially in marine environments where corrosion is particularly problematic.

Alloy Steel Pipe
Some alloy steels have an extremely low rate of thermal expansion or a very consistent and predictable pattern of expansion in specific temperature ranges. This makes them useful when you need a pipe that can maintain a uniform shape and size despite hot environments.
For example, Iron-36% nickel alloy almost doesn’t expand at all during moderate changes in temperatures. And when you add cobalt to the nickel and iron, you get a high-strength alloy steel that has a constant modulus of elasticity and a low coefficient of expansion.
Shape Memory
Sometimes, a metallic material is needed that can return to its previous shape when it experiences heat. This type of material is called a shape memory alloy, and there are very few available on the market. Some alloy steel, however, have this characteristic, with nickel-titanium alloys being one of the most prominent shape memory alloys.
Magnetic Permeability
Alloy Steels also have unique and interesting magnetic permeability characteristics. This has allowed them to become an integral component in designs for switchgear as well as direct current motors and generators.
These advantages have made alloy steel pipe, a popular material in a number of applications, including:
The petrochemical industry
Aircraft turbines
Medical engineering
Steam turbine power plants
Nuclear power plants
The Benefits and Applications of Alloy Steel Pipes

The main applications of alloy steel pipes is power station, nuclear power plant, high pressure boiler, high temperature superheater and re-heater coil etc. of high temperature pipeline and equipments.

How do I choose which alloy steel to use? Selecting the right alloy for a specific application is vitally important in order to achieve a sustainable solution, while cost aspects must also be taken into consideration. There are several stages when material selection needs to be made: new applications and equipment, new processes and process changes, exchange of material due to poor performance, exchange of existing material to minimize cost.
To make the right material selection it is important to get a full picture of the service conditions the steel will face. The first aspects to consider could be material related, for example: corrosion resistance, mechanical strength, fabric ability, fhysical properties, surface aspects.
