class 300 flange

There are different pressure classes of these flanges ranging from Class 150 Monel UNS N04400 Flanges to class 2500, and PN6 to PN64.

The classes define the pressure capacities. The monel 400 flanges have 63% nickel and 28% copper in the composition which makes them stronger.

The Alloy 400 Orifice Flange is a special type that is used to fit pipes together with an orifice. The minimum yield strength of the material is at 195MPa and the minimum tensile strength is 480MPa.

There are different standards to cover the different nominal bore sizes of the flanges. The ANSI B16.5 Monel DIN 2.4360 Blind Flange that has diameters ranging from ? inches to 48 inches in this standard.

The Monel Alloy 400 Threaded Flanges are fitted with pipes with threads. The male threads on the pipe ends fit with the female threads on the threaded flanges. The ASME SB564 Alloy 400 Socket Weld Flanges are usually welded onto the pipes.

Monel 400 is a popular, high performance nickel-copper alloy commonly used in critical and high performance applications.

Monel 400 exhibits high strength, excellent resistance to acidic and alkaline environments, and good ductility and thermal conductivity.

Alloy 400 is highly regarded as one of the best performing engineering alloys.

In fact, in comparison to nickel, the corrosion resistance properties of UNS N04400 Orifice Flange tend to be much higher than nickel itself.

From a human health perspective, the Nickel 400 Spectacle Blind Flange, which is used to clean, inspect or modify piping systems is effective in completely blocking or sealing off pressure vessels that could contain hydrofluoric acid, which again, is a contact poison.

At room temperature settings, Monel 400 exhibits slight magnetic behavior, thus, the use of WNR 2.4360 Reducing Flange could also be extended to applications that require magnetic characteristics to a certain degree.

The Alloy 400 Slip-on Flange is often seen in the marine industry as the alloy exhibits have good resistance to not only seawater but also to high velocity brackish water.

Monel 400 Flanges are made up of a nickel copper super alloy that is corrosion resistant and strong. The material could be welded easily and formed well.

It is also exceptionally resistance to chloride SCC. Flanges are supplied with pitting resistance equivalent that is assuring very good pitting corrosion resistance.

We are manufacturers of ASTM A182 Duplex UNS S32750 / S32760 Flanges show enhanced pitting corrosion resistance in saline environments, brackish waters, bleaching operations, and selected food processing applications.

Offshore marine engineering plants need compenents that meet their rugged demands, components that have mammoth strenght but are light weight.

We are suppliers of WNR 1.4410 Super Duplex Steel Weld Neck Flanges with matching stub-ends that withstand alkalis under higher temperatures.

Super Duplex UNS S32760 Reducing Flanges have a strengthened microstructure, a result of added Nitrogen, allowing fabrication of thin and low-weight flanges that are easy on the pocket.

Duplex 2205 flanges offer good sulfide corrosion resistance, as well as chloride pitting and crevice corrosion resistant superior to 317L.

The combination of chromium, molybdenum and nitrogen give Duplex 2205 flanges good protection from chloride pitting and crevice corrosion, which makes them useful for marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications.

Though it is important to keep in mind that pitting corrosion can be a concern in chloride solutions when oxidizing media is present. In these conditions, the passive (protective) layer of the Duplex 2205 material may be compromised in localized pitting may occur.

Duplex is often found in desalination and pressure vessel equipment located in port cities.

Duplex¡¯s premium mechanical and chemical properties are slightly offset by its difficulty in formability.

These grades are excellent for fixed service simple flange connections, but slightly less so when forming a complex metallic shape. Fortunately, the workability of duplex into complex and rounded structures is less of an issue in structural steel given the wide preference for simple mild steel in non corrosive applications.

Duplex 2205 flanges are made from an austenitic-ferritic stainless steel, which was designed to deliver higher strength and corrosion resistance than 300 series stainless steels.

Both ASME B16.5 and ASME B16.47 have endorsed pipe flanges made from a series of duplex stainless steel grades.

2205 helps users to avoid stress corrosion cracking that is typically seen with 316 and 317.

Duplex 2205 flanges combine the qualities of stress corrosion cracking resistance and high strength derived from being a ferritic alloy along with its austenitic fabrication capabilities.

In comparison to SS316, Duplex 2205 has been tested under reverse bending stresses at room temperature. The results show that the fatigue limit/yield strength is about twice as high for Duplex 2205.

The forging process also consolidates the material to produce an essentially wrought steel structure. The product is subsequently machined to the exact shape and size of finished flange.
