SA 240 GR 2205 Sheet is made from grade 2205 stainless steel, which is a combination of ferritic and austenitic steel.

Duplex stainless steel fasteners are available in Super Duplex, Lean Duplex and Standard Duplex grades, each with specific properties for differenut applications.

Thread friction between the nut and bolt creates a strong, steady and even force holding the componenuts together. The most commonly used ASTM A182 UNS S32205 fastener nuts are regular hex nuts. At the same time, duplex stainless steel fasteners are strong and corrosion resistanut, combining the healthy properties of ferrite and austenite. The material also has a 90ksi minimum tensile strength and a 65ksi minimum yield strength. 2205 duplex stainless steel bolts have an elongation of 25% and a hardness of 217HBW.

Zeron 100?contains 25% chromium and 7% nickel and 3.6% molybdenum along with copper and tungsten additions. Zeron 100 has a 50¨C50 austenitic¨Cferritic structure. It also has greater resistance to chloride pitting, crevice corrosion and stress corrosion cracking than exhibited by the standard 300 series stainless steels.

The service temperature of 2205 duplex stainless steel should be limited to below 600¡ãF. Prolonged exposure to high temperatures can make 2205 stainless steel brittle.

Duplex Stainless Steel offers excellent resistance to corrosion along with very high mechanical strength, which allows for lighter fabrication and greater design flexibility. With this high corrosion resistance, Duplex Stainless Steel provides more uptime than Carbon Steel or conventional Stainless Steel.

In order to convey the pipeline, it is necessary to remove the straight hose in the pipeline. When using various pipelines, various pipelines must be used. When the pipeline is used, the elbow must be used to change the size of the pipeline. When bifurcating, the three-way pipe The flange connection used when the joint is used with various pipe joints, in order to reach the long-distance transmission pipeline, in order to reach the thermal expansion and cold contraction joint or effective connection aging of the pipeline, the long-distance expansion and cold contraction joint is used for the connection of the pipeline. , In the connection of various instruments, there are also the connectors and plugs of the instrument phase.

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.

ASTM A240 UNS S32750 Plate is a stainless steel alloy with excellent resistance to chloride stress-related corrosion cracking.

The Duplex Steel Pipe gets its name from the dual nature present in the microstructure of the alloy. Duplex Stainless Steel Seamless Pipe have good mechanical characteristics and can be used in an as welded condition. Considered to be superior in comparison to austenitic alloys ASTM A312 TP304 or ASTM A312 TP316, the Seamless Duplex Pipe offers much better resistance to corrosion.
