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.

In Hastelloy C276 hex bolts, the chromium content is increased to about 21% and the molybdenum content is reduced to about 13%. Hastelloy C276 Heavy Duty Hex Bolts also provide optimum resistance to environments encountered in reducing and oxidizing conditions in the process stream.

The flange is second most used joining method after welding. Flanges are used when joints need dismantling. It provides flexbility for maintenance. Flange connects the pipe with various equiment and valves. Breakup flanges are adde din the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrelated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls ae required in the selection and application of all these elements to attain a joint, which has acceotable leak tightness.

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.

The use of modular construction is directly influenced by the client¡¯s requirements for speed of construction, quality, added benefits of economy of scale, as well as single-point procurement.
