2. Material and Standard Explanation

Material Grade

• CC60: This grade is designed to provide a good balance between strength and formability. The "CC" likely refers to a specific classification within the ASTM A671 standard related to the chemical composition and mechanical properties. With a yield strength of around 414 MPa, it can be used in a variety of applications where moderate strength is required. The chemical composition is engineered to ensure proper weldability during the EFW process, allowing for the creation of reliable joints.

• CC70: As the numerical value increases, CC70 offers higher strength compared to CC60. With a yield strength of approximately 483 MPa, it is more suitable for applications that demand greater load - bearing capacity. The higher strength is achieved through adjustments in the chemical composition, such as a potentially higher carbon content or the addition of alloying elements in appropriate amounts. This grade is often selected for more demanding projects where the pipes need to withstand higher internal pressures or mechanical stresses.

Standard (ASTM A671)

ASTM A671 is a standard for electric - fusion - welded steel pipe for high - temperature service. It sets strict requirements for the chemical composition, mechanical properties, welding process, and inspection procedures of the welded pipes. Pipes compliant with this standard are designed to be used in environments where they will be exposed to elevated temperatures, ensuring their integrity and safety. The standard also ensures that the EFW process used in manufacturing these pipes meets quality and reliability standards, making the pipes suitable for applications in industries such as power generation, petrochemicals, and refineries where high - temperature fluid transportation is common.

3. Application Areas

CC60

• Power Generation - Low - to - Medium Pressure Steam Lines: CC60 pipes can be used in power plants for transporting steam at relatively lower pressures. Their moderate strength and good weldability make them suitable for this application, ensuring the efficient transfer of steam within the power generation system.

• Petrochemical - Non - Critical Fluid Transfer: In petrochemical plants, CC60 pipes can be used to transfer non - critical fluids such as certain process water or low - pressure hydrocarbon gases. Their cost - effectiveness and ability to withstand the operating conditions of these non - critical applications make them a viable choice.

CC70

• Power Generation - High - Pressure Steam Lines: Due to its higher strength, CC70 pipes are well - suited for high - pressure steam lines in power plants. The high - temperature and high - pressure steam generated in boilers require pipes with sufficient strength to ensure safe and reliable operation, and CC70 meets these requirements.

• Refinery - High - Pressure Process Pipelines: In refineries, where various processes involve high - pressure fluid transportation, CC70 pipes can be used for critical process pipelines. For example, in the transportation of high - pressure hydrocarbon fractions during the refining process, the high strength of CC70 helps to resist the internal pressure and mechanical stresses, ensuring the integrity of the pipeline system.

4. Market and Competition

In the global market, CC60 and CC70 EFW ASTM A671 welded pipes face competition from pipes of other standards and manufacturing processes. For instance, seamless pipes in the same application range may be preferred in some cases for their perceived higher integrity. However, the EFW process of CC60 and CC70 pipes offers cost - advantages, especially for larger - diameter pipes. Their compliance with the ASTM A671 standard, which is widely recognized in the international market, gives them an edge in industries where high - temperature service is a key requirement. Additionally, the ability to produce pipes in a wide range of diameters and wall thicknesses allows them to cater to diverse customer needs, enhancing their competitiveness in the market.
