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.

Superior resistance to hydrochloric acid, aluminum chloride catalysts and other strongly reducing chemicals. Excellent high-temperature strength in inert and vacuum atmospheres.

The flanges also have 8.89 grams per cubic centimeter density and 1370 degrees melting point. The DIN 2.4617 Socket Weld Flanges and other flanges are used in high temperature, high corrosive and high stress applications due to the higher mechanical properties.

Alloy B2 is a highly resistant material to most organic and inorganic acids. It is a reduction resistant material.

Alloy C276 Forged Flange Hastelloy C276 Flanges are made up of the nickel chromium molybdenum alloy that is called hastelloy. The composition includes 50.99% nickel, 14.5% chromium, 15% molybdenum and carbon, manganese, silicon, sulfur, cobalt, iron and phosphorus in it. The Hastelloy C276 Flanges have high melting point of 1370 degrees Celsius. This high melting point allows for higher operating temperatures of the flanges. The material also has 790MPa minimum tensile strength and 355MPa minimum yield strength.

Like other nickel alloys, HASTELLOY C-22 alloy is fairly ductile, has excellent weldability, and is easily fabricated into industrial parts. It is available in sheet, sheet, strip, billet, bar, wire, tube and tube. Typical applications may include: reactors, heat exchangers and columns.

The corrosion resistance property of the alloy is credited to the addition of both Molybdenum and nickel.

Thus these Hastelloy B2 Flanges are considered to be well suited to be used for most chemical process applications in an as-welded condition. Due to lower carbon content in the alloy, there is reduced precipitation of carbides as well as other phases in the heat-affected weld zones, which in turn ensures uniform resistance to corrosion in the flange.

Hastelloy C276 has a low carbon content to minimize grain boundary carbide precipitation during welding to maintain corrosion resistance in the heat affected zone of the welded joint

Hastelloy C276 low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance of welded structures. This nickel alloy resists the formation of grain boundary deposits in the weld heat-affected zone, making it suitable for most chemical process applications in the as-welded state.

Brushing these boards with stainless steel wire after the welding operation usually removes the hot color and likewise creates surface areas that do not require additional pickling.

HASTELLOY C-4 alloy (UNS N06455) is the most (microstructurally) stable of the widely
used nickel-chromium-molybdenum materials, which are well known for their resistance
to many aggressive chemicals, in particular hydrochloric acid, sulfuric acid, and chlorides. This alloy resists the formation of grain-boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in the as-welded condition.

Hastelloy C-276 is the most common corrosion resistant material currently available, but it is not foolproof. Metals should not be exposed to high temperature, strong acid environment. Also, it is easier to work with cold working practices; hot working makes it easier to harden. If hot working, the temperature should be maintained between 1600¡ãF and 2250¡ãF.

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.

The term “flange” is also used for a kind of tool used to form flanges.

It is used in flue gas desulfurizations systems because of its excellent resistance to sulfur compounds and chloride ions encountered in most scrubbers. C-276 alloy has excellent resistance to pitting and to stress- corrosion cracking.

C22 has excellent resistance to oxidation, carburization, and sulfidation at elevated temperatures. However, C22 should not be used at temperatures above 1250¡ãF due to the possible formation of embrittling phases.

A bushing is a type of bearing. Generally speaking, “bearings” facilitate movement between two components while reducing friction. Simple in design, a typical bearing has two surfaces that roll against each other, allowing the two mating parts to move without friction.
