Butt weld flanges are flanges designed to be connected to piping systems by butt welding. There are many specifications of this flange. Butt weld flanges are expensive because of their longer necks and high personnel costs for WN flanges in contact with pipes or fittings, but are preferred for high stress applications. The neck or hub transfers the stress to the pipe.

This exotic alloy is used in oil and gas exploration and is also used in the chemical processing industry. Most processing equipment uses Duplex 2205. Also used by industrial storage and transportation units. Pulp and paper digesters, liquid tanks and paper machines also use Duplex 2205. It is ideal for use in marine environments.

Duplex steel UNS S32205 flanges are extremely durable and can also be easily installed to any size thanks to the different shapes and sizes available.

Duplex 2205, UNS S32205, is a stainless steel material that derives its “duplex” name from a mixed microstructure containing roughly equal portions of ferrite and austenite. This grade is the most popular variety, and this two-phase material is a significant upgrade over 316 stainless steel in terms of yield strength and corrosion resistance.

Duplex steel flanges are hardened alloys that are also very corrosion resistant. The microstructure of this steel consists of a mixture of ferrite and austenite phases. Therefore, they have the characteristics of both ferritic and austenitic stainless steels.

The ASTM A182 F53 UNS S32750 Flange comes under the ASTM A182 specification for high temperature and high pressure services.

The oxidation resistance of these dual phase steel S31803 butt weld flanges is good at high temperatures, but tends to become brittle at temperatures above 300 degrees Celsius, brittle after only 2 hours of exposure at 475 degrees Celsius. These dual phase steel S32205 ring joint flanges also feature high corrosion and erosion fatigue performance as well as lower thermal expansion and higher thermal conductivity than certified.

Duplex 2205 Flat Face Flange Manufacturers recommend this stainless steel grade for industrial applications such as chemical processing, transportation and storage – pressure vessels, tanks, pipes and heat exchangers, sewage scrubbing systems, cargo holds of ships and trucks, petroleum and natural gas exploration and processing equipment – pipelines, pipes and heat exchangers.

Austenitic-ferritic stainless steel variants have higher resistance to stress corrosion cracking, but lower toughness and impact strength than ordinary austenitic 304 and 316 stainless steels. Such materials include grades 2205, F51, F53 and F60. Duplex stainless steels have grown in popularity over the years due to their excellent chemical and mechanical properties, and compared to basic stainless steels, especially given the increased availability, the cost difference is now small.

Compared to other steels, our duplex stainless steel flanges contain more chromium and therefore have good corrosion resistance. Duplex steel slip types on flanges contain about 10% chromium. Duplex Steel Blind Flanges (BLRF) are thermally stable and have moderate strength even at high temperatures.

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

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.

Super Duplex 2507 Butt Weld Flanges have improved corrosion resistance, making themselves suitable for applications prone to stress corrosion cracking, crevice corrosion, pitting, erosion and general corrosion. Due to the characteristics of duplex and super duplex stainless steel butt weld flanges, they are often used in chemical processing, petrochemical, power industry and seawater equipment.

The granular structure of the duplex is a ferrite-austenite hybrid material with a higher strength-to-weight ratio than 304 or 316. It balances the weldability of austenite with pure ferrite and maintains good mechanical toughness in applications exposed to cooler ambient temperatures. Offshore/seawater applications are common uses of this type of steel due to its excellent stress corrosion cracking properties. Therefore, duplexes are often found in desalination and pressure vessel plants located in port cities.

Double butt weld flanges are best suited for hazardous high pressure applications. Butt weld flanges are easily identified by their long tapered neck.

Materials according to ASTM A182 need to meet the required chemical composition. For example, dual phase steel 2205 butt weld flanges must contain elements such as carbon, silicon, nickel, chromium, molybdenum, manganese, phosphorus, columbium and titanium. The material used to produce this Alloy 2205 flange must meet the mechanical performance requirements of the grade specification ordered.

Super duplex steel flanges are very good for servicing a severe corrosive atmosphere like offshore and marine applications.

These high-strength flanges securely seal a range of plumbing modules. The multifunctional flange shows good stability and exhibits enhanced resistance to chloride pitting in marine applications. With standard welding procedures, Super Duplex Flanges can be easily welded to different piping modules.

Duplex 2205 is a nitrogen enhanced duplex stainless steel designed to solve common corrosion problems encountered with 300 series stainless steels. “Duplex” describes a family of stainless steels that are neither fully austenitic (such as 304 stainless steel) nor purely ferritic (such as 430 stainless steel). The structure of 2205 duplex stainless steel consists of a pool of austenite surrounded by a continuous ferrite phase. In the annealed condition, 2205 contains approximately 40-50% ferrite. 2205 is often referred to as the workhorse grade and is the most widely used grade in the duplex stainless steel family.

It is needed when the neck needs to be lengthened. Duplex steel flanges act as extensions.

Due to the alloy’s excellent resistance to dilute hydrochloric acid, Super Duplex 2507 flanges can be used in the chemical processing industry. Another common problem with steel alloys is that they tend to corrode during welding. When the alloy is welded, the temperature is high, and the excess carbon atoms are precipitated to form carbide precipitates.

The oxidation resistance of these dual phase steel S31803 butt weld flanges is good at high temperatures, but tends to become brittle at temperatures above 300 degrees Celsius, brittle after only 2 hours of exposure at 475 degrees Celsius. These dual phase steel S32205 ring joint flanges also feature high corrosion and erosion fatigue performance as well as lower thermal expansion and higher thermal conductivity than certified.

The flange is second most used joining method after selding. Flanges are used when joints need dismantling. It provides flexibility for maintenance. Flange connects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrdlated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls are required in the selection and application of all there elements to attain a joint, which has acceptable leak tightness.
A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails). The term “flange” is also used for a kind of tool used to form flanges.
