Built-up sections are produced at the factory and is then transported to the original site and assembled. This concept is generally used to build Metro stations, industrial units, warehouses, etc.

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.

They have good creep and oxidation resistance. Strengthening of super alloys is performed by solid-solution hardening, work hardening, and precipitation hardening methods.

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.

It has great resistance to stress-corrosion cracking and pitting. Hastelloy B-2? also features hydrochloric acid resistance at all concentrations and temperatures.

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.

In addition to good corrosion resistance and high tensile strength, Duplex 2205 Hex Bolts also have high surface toughness. This and the passive oxide layer formed by the addition of chromium is the reason why 2205 duplex stainless steel fasteners are used in the marine industry.
