ASTM A358 TP 347H is a specific standard established by ASTM International for electric fusion welded (EFW) pipes made from stainless steel grade 347H. The “TP” in the designation stands for “Type” and “P” indicates that the material is intended for pressure service. Here are some detailed characteristics and information about ASTM A358 TP 347H stainless steel EFW pipes:
Composition: Stainless steel grade 347H is an austenitic stainless steel with a higher carbon content than standard grade 347. It contains chromium (17-19%), nickel (9-13%), and a higher amount of carbon (0.04-0.10%) compared to grade 347. The increased carbon content provides enhanced high-temperature strength and improved creep resistance.
Application: ASTM A358 TP 347H EFW pipes are specifically designed for high-temperature applications where resistance to elevated temperatures and corrosive environments is required. These pipes are commonly used in industries such as petrochemical, chemical processing, power generation, and other applications involving high-temperature and corrosive substances.
Manufacturing Process: The pipes are manufactured using the electric fusion welding method. This process involves heating the edges of the stainless steel plates or strips to their melting point and then welding them together under pressure. The EFW process ensures a strong and seamless weld, ensuring the integrity and reliability of the pipes.
Features: ASTM A358 TP 347H stainless steel EFW pipes offer several notable features. They exhibit excellent high-temperature strength, making them suitable for use in applications involving elevated temperatures. The increased carbon content provides improved resistance to intergranular corrosion, making them resistant to sensitization during welding or high-temperature exposure. Additionally, these pipes offer good resistance to general corrosion, oxidation, and scaling.
Corrosion Resistance: ASTM A358 TP 347H stainless steel EFW pipes exhibit good resistance to corrosion in a wide range of corrosive environments, including oxidizing and reducing atmospheres. They offer better resistance to intergranular corrosion compared to standard grade 347 stainless steel, making them suitable for applications where sensitization is a concern.
It’s important to note that specific technical details, dimensions, and mechanical properties may vary based on the specific requirements of each ASTM A358 TP 347H stainless steel EFW pipe. Consulting the relevant ASTM A358 standard or contacting the manufacturer or supplier can provide more detailed and precise information for your specific application or project.
