Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel’s resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen
Completely and infinitely recyclable, stainless steel is the ¡°green material¡± par excellence. In fact, within the construction sector, its actual recovery rate is close to 100%.
Stainless steel is also environmentally neutral and inert, and its longevity ensures it meets the needs of sustainable construction. Furthermore, it does not leach compounds that could modify its composition when in contact with elements like water.
Stainless steel must contain at least 10.5 percent chromium. Depending on the grade, it may contain much higher chromium levels, and additional alloying ingredients like molybdenum, nickel, titanium, aluminum, copper, nitrogen, phosphorous or selenium.
In addition to these environmental benefits, stainless steel is also aesthetically appealing, extremely hygienic, easy to maintain, highly durable and offers a wide variety of aspects. As a result, stainless steel can be found in many everyday objects. It also plays a prominent role in an array of industries, including energy, transportation, building, research, medicine, food and logistics.

304 and 304L are austenitic alloys, which means that a nonmagnetic solid solution of ferric carbide or carbon in iron is used in giving this stainless steel its corrosion-resistant properties.

The Stainless Steel Fittings Manufacturers produce these fittings with the addition of manganese, phosphorus, carbon, silicon, and sulfur apart from the 2 main elements.

The installation process for a 304 stainless steel SO flange is relatively simple. Firstly, the pipe end is prepared by cleaning it and ensuring that 1.4301 flange is free from damage and debris. Next, the S30400 flange is positioned on the pipe and aligned to ensure a smooth flow of the fluid or gas. Finally, the bolts are tightened to the manufacturer’s specifications to ensure a secure connection, taking care not to overtighten the bolts as this can cause damage to the flange or pipe.

Type 316 is much more resistant to sulfuric acid solutions than any other chromium-nickel type. Type 316 is resistant to acid concentrations up to 5% at temperatures up to 120¡ãF (49¡ãC). This type has excellent resistance to higher concentrations at temperatures below 100¡ã F (38¡ã C).

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.

A wide variety of stainless steel flanges are all available at HT PIPE, including weld necks, slip-ons, threaded, socket weld, lap joints, blinds, and hub blinds.
