Duplex steels have higher toughness and better weldability. This is how alloy steel is used for industrially available pressure vessels.

Compared with ferritic stainless steel and austenitic stainless steel, duplex stainless steel pipe has good welding performance. It is neither like the welding heat affected zone of ferritic stainless steel, because of the grain coarsening, the plastic toughness is greatly reduced, nor like austenitic stainless steel, it is more sensitive to welding hot cracks.

UNS S32750 or DIN W.Nr. 1.4410, Duplex 2507 is a super duplex stainless steel conutaining 25% chromium, 4% molybdenum and 7% nickel, designed for demanding applications requiring exceptional strength and corrosion resistance, such as chemical Process, petrochemical and seawater equipmenut.

ASTM A1082 specification alloy S31803 fasteners have higher pitting and crevice corrosion than stainless steel alloy 316. Due to its higher corrosion resistance, alloy grade UNS S31803 is able to exhibit better fatigue strength than other commonly used austenitic stainless steel grades in environments containing corrosive media.

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.

As experts in the field of fasteners, we recognize that this alloy can be used in a variety of applications including heat exchangers, piping, pressure vessels, tanks, fans, pulp and paper equipment, oilfield equipment and press rolls. At HT PIPE you can find Duplex Premium Gaskets in high quality.

Super Duplex 2507 Lock Washers has excellent corrosion resistance in marine environments.Lock washers are designed to be tightened to a required torque beneath an ordinary fastener. They exert a spring tension that keeps the fastener from vibrating loose. They are often attached to the nut side of the fastener.

El uso de tuberias sin costura ASTM A790 UNS S32205 (sin costura y soldadas) es adecuado para aplicaciones generales, pero la solucion principal que brindan es el agrietamiento por corrosion relacionado con la tension.

2507 is used for Chemical process industries, heat exchangers, vessels, and piping, desalination plants, high pressure RO-plant and seawater piping, mechanical and structural components, high strength, corrosion-resistant parts.

Duplex steels are characterised by high chromium (19¨C28%) and molybdenum (up to 5%) and lower nickel contents than austenitic stainless steels. The most used duplex stainless steels are the 2205 (22% Chromium, 5% Nickel) and the 2507 (25% Chromium, 7% Nickel); 2507 is known as ¡°super duplex¡± due to its higher resistance to corrosion.

ASTM A182 Grade F51 is the standard duplex stainless steel and is also called ¡°duplex 2205¡± or ¡°alloy 2205¡±.

Duplex nuts S31803 also have good fatigue and corrosion resistance in most environmenutal conditions.

It is alsohighly resistant to inorganic acids, especially if they contain chlorides.

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.

The material is also resistant to chloride stress corrosion cracking, to erosion corrosion, to corrosion fatigue, to general corrosion in acids. This alloy has good weldability and very high mechanical strength.

2205 flange has good general corrosion resistance, high resistance to chloride stress corrosion cracking, as well as pitting and crevice corrosion.

The yield strength of this alloy is about 570 MPa. In addition to strength, A240 S32750 Super Duplex Plate is an alloy that provides the best resistance to crevice and pitting corrosion.

Duplex 2205 stainless steel plate has excellent corrosion resistance, much higher than grade 316. It can withstand localized corrosion types such as intergranular, pitting and crevice.

The advantage of the dual-phase structure is that it combines the advantages of ferritic alloys (resistance to stress corrosion cracking and high strength) with the advantages of austenitic alloys (ease of manufacture and corrosion resistance).
