Carbon Steel Flanges are widely used across multiple industries, particularly in the oil and gas sector, for applications such as process seawater systems, firewater systems, and subsea pipeline works. They also play a critical role in the construction of pressure vessels, valves, and heat exchangers. Beyond the oil and gas industry, these flanges are essential in various sectors such as pollution control (e.g., desulfurization systems), paper and pulp industries, desalination plants, mining, metallurgical, and marine applications.
Renowned for their strength and corrosion resistance, Carbon Steel Flanges are ideal for use in chemical industries, where they must endure exposure to aggressive substances like acids and alkalis. Their robust construction ensures that they perform effectively in heavy-duty industrial environments, offering long-lasting durability and reliability.
Upon dispatch, all carbon steel flanges are carefully inspected, counted, and listed with comprehensive details, including the manufacturer's name, quantity, and other relevant information, ensuring efficient and accurate delivery.
