Lugged Pattern Super Duplex Butterfly Valves

Super duplex TTV lugged butterfly valves made from UNS S32750 with a shaft constructed from 904L stainless steel offer exceptional corrosion resistance and mechanical strength, making them well-suited for demanding industrial applications. The use of UNS S32750, a super duplex stainless steel, provides enhanced durability and corrosion resistance compared to conventional stainless steels.

Key Features

Key features and benefits of Super Duplex Lugged Pattern Butterfly Valves.

Key Features

The combination of UNS S32750 super duplex stainless steel for the valve body and 904L stainless steel for the shaft results in a dual-material construction that maximises durability.

Key Features

The lugged design of these butterfly valves offers practical advantages in terms of installation and maintenance. Featuring threaded inserts on either side of the valve body, the lugged design allows for direct bolting to the piping system without the need for additional flanges.

Key Features

UNS S32750 provides enhanced strength and corrosion resistance, while 904L stainless steel, known for its resistance to a variety of corrosive media, reinforces the valve shaft. This dual-material approach ensures a robust and reliable performance, even in harsh operating conditions.

Frequent Interrogation

Among the numerous outstanding attributes of super duplex stainless steel, its remarkable corrosion resistance stands out prominently. Additionally, it can withstand temperatures of up to 150 degrees without succumbing to corrosion or cracking.

When comparing super duplex stainless steel to 316, a substantial enhancement in performance is evident. Super duplex stainless steels exhibit three to four times higher yield strength and approximately twice the resistance to pitting corrosion, all while being priced at less than twice the cost.

2205 Stainless Steel surpasses the standard marine grades 316 and 316L, representing a recent advancement over the past 10-20 years by metallurgists. This stainless steel variant not only exhibits superior strength compared to the conventional marine grade 316 but also delivers significantly enhanced corrosion resistance.

2507 Super Duplex Stainless Steel Tubes have a tensile strength of 1,00,000 psi and yield strength of 70,000 psi. Super Duplex Welded Pipes are high in demand due to their low cost but are considered weaker compared to the other pipes.

Alloy 2507 is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment.

Valves crafted from 2205 Stainless Duplex Steel consist of a duplex-grade steel characterized by both high strength and excellent corrosion resistance, thanks to the presence of austenitic and ferritic phases in its microstructure. This metallurgical composition renders these steels highly versatile for use across a broad spectrum of applications.

Super Duplex stainless steels incorporate a higher alloying addition of 25% chromium, in contrast to duplex stainless steels, which are based on an alloying addition of 22% chromium. This augmentation in chromium content directly enhances the pitting corrosion resistance of the material.

Super Duplex is a dual-phase alloy consisting of austenitic and ferritic structures, incorporating iron, chromium, nickel, and molybdenum. It exhibits excellent resistance to pitting, impressive tensile strength, and elevated resistance to stress corrosion cracking at moderate temperatures, surpassing conventional austenitic stainless steels in performance.

Super duplex stainless steel, an extension of duplex stainless steel, distinguishes itself with increased chromium content at 25%, nickel content at 7%, and molybdenum content at 4%. With higher concentrations of these elements, it exhibits superior corrosion resistance compared to standard duplex stainless steel.

One standout attribute of super duplex stainless steel is its remarkable resistance to corrosion, allowing it to withstand temperatures of up to 150 degrees without succumbing to corrosion or cracking.
