Nakamura Stainless of Pulau Ujong, Singapore, is a well-established stainless steel RTJ (Ring Type Joint) flange manufacturer and supplier. Nakamura Stainless RTJ flanges are designed to deliver enhanced sealing efficiency in high-temperature and high-pressure piping systems, widely utilized in oil and gas, petrochemical, and power generation industries. Famous for precision manufacture and corrosion resistance, Nakamura Stainless provides RTJ flanges complying with tough international standards. Nakamura Stainless emphasizes longevity and leak-tight connections to provide safety and reliability in mission-critical industrial processes.
Steel RTJ flanges generally consist of superior alloys such as 304 and 316 stainless steel, providing superior resistance against corrosion and mechanical stress. These flanges possess tensile strengths between 515 and 860 MPa depending on the grade. Their design feature involves an accurately machined groove that can fit a metal ring gasket, creating a high-integrity, tight seal even under harsh pressure and temperature. Their strong construction makes RTJ flanges perfect for harsh and demanding environments.
