Super Duplex Headers Plugs are superior sealing products that are used in the most hostile industrial applications where extreme corrosion resistance, high mechanical strength and long service life are required. These plugs are produced using super duplex stainless steel alloys which provides a much better performance than the duplicates of duplex and austenitic stainless steels.
Super Duplex Steel Header Plugs are widely used in heat exchangers, pressure vessels, offshore systems, and high-pressure piping where exposure to chlorides, seawater, chemicals, and high temperatures is common. They are the best in terms of their high resistance to pitting, crevice corrosion, and stress corrosion cracking hence they are highly sought after in critical applications.
Jade Alloys provides high-precision engineered super duplex header plugs meeting the international standards and provide consistent performance in the most strenuous operating conditions.

Grades of Super Duplex Header Plugs
Jade Alloys manufactures Super Duplex Header Plugs in grades specifically developed for extreme corrosion and high-pressure environments.
Common Grades Offered:
Super Duplex 2507 (UNS S32750)
Excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking.
Super Duplex UNS S32760
Enhanced corrosion resistance with superior performance in aggressive chemical and marine environments.
Custom Super Duplex Grades
Available as per client-specified chemical composition, standards, or service conditions.
These grades provide exceptional strength, longer service life, and reduced maintenance costs in comparison to duplex 2205 and conventional stainless steels.
What is the difference between Duplex and Super Duplex Header Plugs?
The key distinction between Super Duplex and Duplex Header Plugs is the chemical content, mechanical strength and corrosion resistance. Duplex Header Plugs often of grades including Duplex 2205 are a balanced set of reasonable corrosion resistance, great strength and cost efficiency, and so they are appropriate in moderately aggressive applications, such as standard heat exchangers, chemical processing units and oil and gas systems with regulated chloride content. Conversely, the Super Duplex Header Plugs are made of advanced alloys like UNS S32750 or S32760 which have more chromium, molybdenum and nitrogen. This gives super duplex grades a much higher yield strength and high resistance against pitting, crevice corrosion, and chloride stress corrosion cracking, particularly in seawater, offshore, and other highly corrosive chemical service. This has led to the use of the super duplex header plugs in extreme operating conditions that require long-term reliability, minimum maintenance and high performance.
