We offer These Duplex Steel Pipe Fittings as per DIN, ISO, JIS or ANSI Standard.
Water resistance: Duplex steel pipe fittings exhibit excellent corrosion resistance, especially in harsh environments such as chloride, acid and sea water. This strength helps extend the life of the fitting and reduces maintenance costs.
High Strength: Duplex stainless steel combines high strength with excellent flexibility and rigidity. This makes double steel pipe inserts suitable for applications where high strength is required, such as offshore marine environments, chemical plants and oil and gas industries.
Resistance to Stress Corrosion Cracking (SCC): Duplex steel has excellent resistance to stress corrosion cracking compared to austenitic and ferritic stainless steel This property makes it ideal for use in areas where corrosion and stress are common, e.g petrochemical plants and desalination facilities
Cost: Despite its superior properties, duplex steel pipe fittings can often be cost-effective compared to other corrosion-resistant alloys, such as super-austenitic and nickel-based ones. This cost savings becomes especially apparent when The longer service considers the life expectancy and reduced maintenance of double metal fixtures.
Excellent weldability: Duplex steel exhibits excellent weldability, facilitating the fabrication and installation of pipe fittings. This property makes designing complex pipeline systems desirable and facilitates efficient design.
Duplex Steel Pipe Fittings applications are as diverse as the industries they serve driven primarily by the aerospace, railway, construction and automotive industries with petrochemical, nuclear, medical, Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Nuclear, Thermal Power plants, Paper and Pulp, marine and mining, etc.
Oil and Gas Industry: Duplex steel pipe fittings are widely used in offshore and onshore oil and gas exploration, production, refining and transportation. Even in aggressive environments containing chloride ions, due to their excellent corrosion resistance and high strength, they are used for subsea pipelines, risers, and various applications; flows and other controls are fine.
Chemical applications: Duplex steel pipe fittings are widely used in chemical plants where resistance to chemical corrosion, acids and high temperatures is required. They are commonly used in reactors, heat exchangers, storage tanks and piping systems used in corrosive water treatment.
Desalination equipment: In areas where seawater is converted to fresh water, duplex steel pipe fittings are preferred due to their excellent resistance to seawater and salt solution corrosion, and they are used in various applications such as pumps, valves, inside heat exchangers and piping systems.
Pulp and Paper Industry: The pulp and paper industry uses duplex steel pipe fittings to handle corrosive chemicals, bleaching agents and high temperatures involved in the design. They are used in digesters, bleaching towers, evaporators, and piping systems and have important corrosion resistance and abrasion resistance.
Power generation: In power plants, duplex steel pipe fittings are used in critical applications like boilers, heat exchangers, condensers, piping systems, etc. They provide corrosion resistance to high-temperature steam, aggressive cooling water and chemicals used in power generation processes.
Understand application requirements: Start by thoroughly understanding your requirements, including operating conditions, water consumption, temperature, pressure, corrosion potential, and environmental factors. This understanding will help you determine the most important features that duplex steel pipe fittings should have.
Material Selection: Select stainless steel with an adequate duplex based on specific application requirements. Typical awards include Duplex 2205 (UNS S32205/S31803) and Super Duplex 2507 (UNS S32750). Consider corrosion resistance, strength and heat resistance when choosing a durable material.
Size and Design: Determine the required size, thickness, and pipe fittings specifications based on piping system design, flow rate, and pressure requirements. Ensure fittings meet standards and specifications such as ASTM, ASME, ANSI, and DIN.
Corrosion resistance: Determine requirements for corrosion resistance based on moisture content, corrosive chemicals, chloride, acids, and other corrosive elements in the environment. Select duplex steel pipe with adequate corrosion resistance to ensure durability and reliability.
Pressure and Temperature Analysis: Consider operating pressure and temperature conditions to ensure that duplex steel pipe fittings can withstand the required pressure and temperature levels without failure or distortion. Ensure the fitting is calibrated to your application’s specific pressure and temperature conditions.
Duplex steel pipe fittings are less susceptible to galvanic corrosion than many other metals, but they can still experience it in certain conditions. Factors like contact with more noble metals or exposure to chloride-rich environments increase the risk. Proper material selection, isolation techniques, cathodic protection, and careful design and installation are essential to mitigate this. While duplex steel offers superior corrosion resistance, it’s prudent to consider galvanic corrosion potential and take preventative measures in critical applications.
Yes, duplex steel pipe fittings are highly recyclable. Duplex stainless steel is a stainless steel composite of iron, chromium, nickel and molybdenum, all of which are recyclable materials. Recycling duplex steel pipe fittings requires melting the metal to remove materials used to produce the process, which is then used to make other steel products. Recycling duplex steel fittings that can be manufactured conserves natural resources and reduces energy consumption and greenhouse gas emissions associated with steel production, making it an environmentally friendly alternative. Besides the corrosion-resistant properties of duplex steel, recycled products contribute to longevity.
Yes, duplex steel pipes can be used for underground applications. Their excellent corrosion properties make them suitable for areas where water, soil, and subsurface conditions can cause corrosion, among other factors, including chloride-induced corrosion resistance, pitting and stress corrosion cracking, duplex steel oil-gas, chemical processing, and city -They are especially suitable for underground piping systems in industries such as buildings Adequate coatings and cathodic protection can provide the steel duplex used in underground applications longer again, ensuring longer service life, and reducing maintenance requirements.
