Product Description

Product Description

Alloy steel pipe

Alloy steel pipes are hollow tubes made from alloy steel containing a certain proportion of alloying elements. Alloy steel tubes offer excellent mechanical properties, corrosion resistance, and high-temperature resistance, making them widely used in industries that require high strength, high temperatures, or corrosion resistance.

ASTM A335 Alloy Pipe is often called as chrome moly pipe because of the chemical contain of Molybdenum (Mo) and Chromium (Cr). ASTM A335 Alloy Pipe is the seamless ferritic Pipe for high temperature service. ASTM A335 Alloy Pipe finds high usage in power generation industry and petrochemical industry, because of its resistance to corrosion, tensile strength, strength for high temperature and its cost-effectiveness.

Chome moly pipe is popular in ASTM A335 standard material P5, P9, P11, P12, P22, P91 and P92.

Classification Based on Alloying Element Content
Low-alloy steel pipe: Low-alloy steel pipes have an alloy element content of less than 2 %. Characterized by lower cost, it is suitable for some common mechanical and structural purposes that do not require high strength and corrosion resistance.

Medium-alloy steel pipe: Medium alloy steel pipes usually contain between 2 % and 10 % of alloying elements and have better mechanical properties, high temperature, and corrosion resistance. These tubes are mainly used in industrial applications that are subject to higher temperatures or larger loads.

High-alloy steel pipe: High-alloy steel tubing typically contains more than 10 % alloying elements and has extremely high strength, corrosion resistance, and high-temperature resistance. Common high alloy steel pipe materials include alloy steel pipes that contain large amounts of chromium, nickel, molybdenum, and other elements.

Classification Based on Major Alloying Elements Contained
There is a wide range of alloy steel tubes, according to different combinations of alloying elements, which can produce different performance characteristics to adapt to different needs of use. Here are some common types of alloy steel tubes.

1.Molybdenum alloy steel pipe;
2.Chromium alloy steel pipe;
3.Manganese alloy steel pipe;
4.Nickel alloy steel pipe;
5.Titanium alloy steel pipe;
6.Chromium-molybdenum alloy steel pipe;
7.Carbon-manganese alloy steel pipe;

Classification Based on Manufacturing Process
1.Seamless alloy steel pipe;
2.Welded alloy steel pipe.
