ASTM A182 F5 flanges are a method of connecting pipes, valves, pumps, and other equipment to form a piping system. It also facilitates cleaning, inspection or modification.

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.

Alloy 310S, like 309S, is known for high temperature applications. Both alloys work well at temperatures up to 2000¡ãF, especially where oxidation resistance is required. 310 stainless steel is an austenitic chromium-nickel stainless steel with good oxidation and corrosion resistance due to the high ratio of chromium to nickel.

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.[1][2] Most commonly, the phrase “alloy steel” refers to low-alloy steels.

Alloy 625 is a nickel-chromium alloy with high strength, excellent machinability and excellent corrosion resistance. Operating temperature ranges from cryogenic to 1800¡ãF.

This combination of elements also provides excellent resistance to a variety of unusually severe corrosive environments as well as high temperature effects such as oxidation and carburization.

304, 304H and 304L all have the same nominal chromium and nickel content and therefore have the same corrosion resistance, ease of manufacture and weldability.

Applications and Materials
Normalizing is mainly used for normalizing the structure of carbon steel and low alloy steel after forging, hot rolling or casting. The hardness obtained after normalizing depends on the steel dimensional analysis and the cooling rate used (approximately 100-250 HB).

Inconel 725 bolt material meets ASTM B446, B564, F467, F468, UNS N06725, DIN EN 2.4856, AMS 5666 and BS 3076 specifications and is adequate for demanding strength, corrosion resistance and high temperature applications up to 1000o C (1800o F).

Steel flanges provide an easy access for cleaning, inspection or modification. They usually come in round shapes but they can also come in square and rectangular forms. The flanges are joined to each other by bolting and joined to the piping system by welding or threading and are designed to the specific pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.

A flange can be a plate for covering or closing the end of a pipe. This is called a blind flange. Thus, flanges are considered to be internal components which are used to support mechanical parts.

There are different types of flanges based on the functionality such as the blind flange, slip on flange and orifice flange.ASTM A105 carbon steel can be forged at temperatures in the range of 2200 to 1700 F followed by quenching and tempering or normalizing.

The flange connection type usually comes with double units, with a gasket and some bolts & nuts to connect each other. (Firstly pipes are welded on the flanges, then valves and other equipment could be installed on flanges.)

When connecting these parts, put gasket in the middle of two flanges, then tightening the flange screws, so the two will be connected together tightly.

Hastelloy C276 has excellent resistance to pitting, acid, crevice corrosion, and also in reducing the environment. This alloy is most widely used in many industrial applications because of its excellent qualities and features.

Chromium oxide is created when chromium and steel react, which gives the corrosion resistant properties to stainless steel. This is one of the reasons stainless steel is great for sanitary valves and other sanitary items, because it does not corrode.
