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

Zeron 100 is highly resistant to corrosion in a wide range of organic and inorganic acids. The copper content gives excellent resistance to corrosion in many oxidising acids. This alloy is also highly resistant to strong alkalis.

Duplex 2205 bolts are among the most commonly used duplex grades. These are called standard duplex steel fasteners. There are different types of fasteners such as studs, bolts, nuts, screws, etc. Duplex stainless steel fasteners are used in chemical processing, transportation, storage, oil and gas, marine, paper and pulp, wine and many other industries. A wider range of applications is possible due to the combination of corrosion resistance, high temperature capability and high pressure resistance of Duplex Steel 2205 Nuts and Bolts.

Debido al peso ligero de la tuberia soldada ASME SA790 de acero duplex UNS S32205, se utiliza en procesos de ingenieria aeroespacial y nuclear. Tambien se utiliza en la industria automotriz y de la construccion debido a su alta resistencia al desgaste y capacidad para trabajar en ambientes de alta tension.

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.

Duplex stainless steels are considered resistant to stress corrosion cracking because they are not as resistant to this form of corrosion as ferritic stainless steels.

The yield strength of duplex stainless steel is twice that of austenitic stainless steel. This feature allows designers to reduce weight when designing products, making this alloy more cost-effective than 316, 317L.

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

ASTM A789 A789M Covers Grades of nominal wall thickness, stainless steel tubing for services requiring general corrosion resistance, with particular emphasis on resistance to stress corrosion cracking. These steels are susceptible to embrittlement if used for prolonged periods at elevated temperatures.

2205 duplex stainless tubing material, which is why it is referred to as a self-repairing layer.

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.

ASTM A240 Duplex 2205 Sheets contains approximately 40-50% ferrite. Often referred to as the work horse grade 2205 is the most widely used grade in the duplex family of stainless steels.

The chemical composition of 2205 Duplex Stainless Pipe consists of the elements being used in the following content i.e. – 22% chromium, 3% molybdenum and about 5 to 6% nickel. Because of the content, in terms of quantity of chromium present in the alloy of this grade, this stainless steel is also referred to as 22cr Duplex 2205 Pipe.

Duplex 2205 fasteners are made from cost-effective, long-lasting and corrosion-resistant steel. The grade of steel used to make fasteners can be ferritic, austenitic or dual phase steel. Duplex materials have the strength qualities of ferritic steels and the corrosion-resistant qualities of austenitic steels.

The raised face allows for the flange to have more bolt holes and connection surface while the welded neck grips the pipe in place. The applications are oil and gas, petroleum, petrochemical and other industrial applications.

It reaches the phase balance of austenite and ferrite in roughly same volume fraction.

The advantages of duplex steels include: good weldability and machinability, high resistance to corrosion fatigue, resistance to stress corrosion cracking (especially chloride stress corrosion cracking), erosion and high energy absorption.
