ASTM A135 Pipe: Composition, Properties, and Uses

ASTM A135 is a standard developed by the American Society for Testing and Materials (ASTM), mainly for the manufacture and use of resistance welded steel pipes. This kind of pipe is widely used in various engineering fields, especially those where certain requirements are placed on the material but extremely high standards are not required. In this article, we will conduct a detailed analysis of ASTM A135 pipe from three aspects: composition, properties, and uses.

ASTM A135 Pipe: Composition, Properties, and Uses

ASTM A135 Pipe: 1. Composition

The ASTM A135 standard does not strictly stipulate the specific composition of pipes, because it is a standard that mainly considers the manufacturing process and final product performance. However, usually, A135 pipes are mainly carbon structural steel, which may contain a small amount of alloying elements such as manganese, silicon, etc. to improve the mechanical properties of the material. The carbon content is usually low to ensure good weldability and formability.

In addition, it may also contain trace amounts of impurity elements such as sulfur and phosphorus. These elements have a certain impact on the performance of the material, so strict control is required during the production process.

ASTM A135 Pipe: 2. Properties

1. Mechanical Properties: ASTM A135 pipe has good mechanical properties, including moderate tensile strength and yield strength. Its elongation and area shrinkage are also high, showing good plasticity, which is very beneficial for the forming and installation of pipes.
2. Weldability: Due to its low carbon content, A135 pipe has excellent weldability. Whether it is resistance welding or other welding methods, satisfactory welding results can be obtained. This is critical both for pipe production and on-site installation.
3. Corrosion resistance: The corrosion resistance of A135 pipes is relatively average, not as good as stainless steel and other materials. However, it can still maintain a certain degree of corrosion resistance under ordinary atmospheric environments and dry conditions. In humid or corrosive environments, it is recommended to take appropriate anti-corrosion measures, such as galvanizing, painting, etc.
4. Dimensional accuracy: The ASTM A135 standard has certain requirements for the dimensional accuracy of pipes, including outer diameter, wall thickness, length, etc. Manufacturers need to produce in accordance with standard requirements to ensure that the dimensional accuracy of pipes meets usage requirements.

ASTM A135 Pipe: 3. Uses

ASTM A135 pipes are widely used in various fields because of their excellent performance and moderate price. Here are some of the main uses:

1. Building and Structural Engineering: A135 pipes are often used in building and structural engineering, such as support structures for bridges, highways, tunnels, etc. Its good mechanical properties and weldability make it ideal for these projects.
2. Liquid and gas transportation: Because A135 pipe has good sealing and certain corrosion resistance, it is often used to transport liquids and gases such as water, oil, and natural gas.
3. Machinery manufacturing: In the field of machinery manufacturing, A135 pipes are often used as raw materials for various mechanical parts, such as shafts, sleeves, brackets, etc. Its excellent mechanical properties and processability enable it to meet the manufacturing requirements of various complex mechanical components.
4. Other fields: In addition to the above fields, A135 pipes are also widely used in other fields such as agriculture, chemical industry, and electric power. For example, in the agricultural field, it is often used as a water pipe for irrigation systems; in the chemical industry, it is used as a connecting pipe for various chemical equipment.

Conclusion

To sum up, ASTM A135 pipe is a steel pipe product with excellent performance and a wide range of uses. Its excellent mechanical properties, weldability, and moderate price make it widely used in various fields. However, it should be noted that due to its relatively general corrosion resistance, appropriate anti-corrosion measures need to be taken when used in humid or corrosive environments. In addition, when selecting and using A135 pipes, reasonable design and selection must be carried out according to the specific use environment and requirements.
