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.

Hastelloy B3 fasteners offer the same excellent resistance to hydrochloric acid and other strong reducing chemicals as other B alloys, including B2, but with significantly enhanced thermal stability and easier fabrication. In addition, B3 fasteners are highly resistant to attack from cut lines and heat affected zones. Like B2 alloys, B3 fasteners are not recommended for use in the presence of iron or copper salts that can cause rapid corrosion failure.

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

HASTELLOY C276 is a Nickel-chromium-molybdenum wrought alloy that is considered the most versatile corrosion resistant alloy available. This alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in an as welded condition. Alloy C-276 also has excellent resistance to pitting, stress-corrosion cracking and oxidizing atmospheres up to 1900¡ãF. Alloy C-276 has exceptional resistance to a wide variety of chemical environments.

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

C276 is a nickel-molybdenum-chromium superalloy with tungsten added, designed for excellent corrosion resistance in a variety of harsh environments. The high nickel and molybdenum contents make nickel steel alloys particularly resistant to pitting and crevice corrosion in reducing environments, while chromium is resistant to oxidizing media.

C276 is forged between 2250/1750oF (1230/955oC) and then soaked at the forging temperature for 30 minutes per inch of billet or ingot section thickness. Forging should begin immediately, the billet is removed from the reheat furnace, a 25/40% reduction helps retain as much internal heat as possible. For optimum corrosion resistance, forged parts should be subsequently annealed. See Heat Treatment.

Alloy B2 also has excellent resistance to pitting and stress corrosion cracking.

Hastelloy B3 Flanges are also being offered in customized sizes, and shapes to our valuable clients.
