Aman Pipes and Tubes is a well-known Hyderabad-based manufacturer and supplier of high-quality Stainless Steel 347 and 347H Electropolished Pipes. These pipes are renowned for their strength, accuracy, and resistance to corrosion. Made from sophisticated technology and rigorous quality checks, these pipes are highly in demand. Aman Pipes and Tubes is dedicated to customer satisfaction and industry standards and supplies these pipes to a variety of industries ranging from chemical and pharmaceutical to power generation sectors. Their 347 and 347H Electropolished Stainless Steel Pipes are highly relied upon for high-stress and high-temperature applications because of their high performance and reliability.
Stainless Steel 347 and 347H Electropolished Pipes are stabilized austenitic stainless steels with chromium (17–20%), nickel (9–13%), and columbium/tantalum for resistance to intergranular corrosion. 347H has greater carbon for improved high-temperature strength. These pipes have good oxidation resistance and mechanical properties, such as a tensile strength of approximately 515 MPa, yield strength of 205 MPa, and elongation of 35%. Electropolishing improves smoothness of the surface, cleanliness, and resistance to corrosion, so these pipes are suitable for delicate and high-purity applications.

These pipes have broad applications in high-temperature chemical processing, food processing equipment, and petroleum refining processes. The stability of these pipes against intergranular corrosion and high resistance to heat make them ideal for heat exchangers, pressure vessels, and boiler tubes. In pharmaceuticals and biotechnology, the electropolish finish guarantees low contamination and ease of cleaning. They are also popular in aerospace, pulp and paper, and nuclear use where strength, cleanliness, and toughness are required. Their durability to work in tough environments expands their application in offshore and marine environments, too.
