A flange is a ring of steel (forged, cut from plate, or rolled) designed to connect sections of pipe, or to join pipe to a pressure vessel, valve, pump or other integral flanged assembly. Flanges are joined to each other by bolts, and to the piping system by welding or threading (or loose when stub ends are used). Stainless steel flange simplified as SS flange, it refers to the flanges that made of stainless steel. Common material standards and Grades are ASTM A182 Grade F304/L and F316/L, with pressure ratings from Class 150, 300, 600 etc and to 2500. It used in more industries than carbon steel as stainless steel has better resistant performances on corrosion environment and always provides with a good appearance.

These grades of austenitic stainless steels are the most versatile and widely used stainless steels.Type 304 and 304L stainless steel pipe can perform well in high temperature and harsh environments.

Featuring 304 stainless steel for very good corrosion resistance, this GRAINGER APPROVED weld neck flange can be attached to a system via a circumferential weld at the neck. The welded area can be easily examined by radiography. Matched pipe and flange bore reduces turbulence and erosion inside the pipeline. Flange is excellent for use in your critical applications and is ideal for use with air, water, oil, natural gas, and steam.

Bolts hold materials together by applying pressure that tightens the bolt head to the nut. They mate with corresponding threaded holes and nuts to form a bolted connection. Their external thread design makes them easy to tighten with a wrench or pliers. The purpose of a bolt depends on its shape, head type and size. The most common types of bolts include hex head bolts, U-bolts, eye bolts, brackets, lifts, plows and flanges.

Stainless steel pipe is a hollow and longitude steel, economical steel section is circular. Stainless steel pipes have been widely used in petroleum, chemical, medical, food, light industry, equipment and structural parts, etc. Also, when torsional and torsional strength are equal, stainless steel is lighter, so it is used for equipment parts and project structures. It is also used to produce barrels and shells for various conventional weapons. This kind of pipe is divided into: stainless steel seamless pipe and stainless steel welded pipe.

The surfaces of these parts have a mottled appearance due to general corrosion. Additionally, they weaken the alloy and require frequent replacement to prevent catastrophic effects. Because the alloy has good resistance to general corrosion or uniform erosion, from a financial standpoint, the industry can use 304 stainless steel welded fittings without denting their pockets.

Stainless steel pipes are long, hollow tubes that are used for a wide range of industrial applications. They are produced by two distinct methods which result in either a welded or seamless pipe. Alloy 304 stainless steel pipe provides enhanced strength and corrosion resistance and can be used for all types of fabrication processes, especially those that are subjected to outdoor environmental conditions.

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.

316 Stainless steel is a broad class of alloyed steels that contain a certain percentage of chromium to protect the metal from corrosion and related damage. The amount of chromium in the alloy¡ªand the amount of other metallic elements¡ªwill vary depending on the grade of stainless steel used.

S31803 is the Unified Numbering System (UNS) designation for the original duplex stainless steel. The UNS system was created by multiple trade groups in the 1970s to reduce confusion when the same alloy was called different things, and vice versa. Each metal is represented by a letter followed by five numbers, where the letter represents the metal series, i.e. S for stainless steel.

For paper mill applications requiring lower alloy grades that do not have sufficient corrosion resistance. Based on a 22% chromium content, they have a combined austenitic:ferritic microstructure that provides greater strength, corrosion resistance and cost-effectiveness.

The UNS S31803 (ASTM F51) specification has been largely superseded by UNS S32205 (1.4462, ASTM F60). This reflects their desire to maximize the alloy’s corrosion properties, thanks to the development of the AOD steelmaking process, which allows for tighter control of composition. In addition, it allows to influence the nitrogen addition level rather than just being present as a background element. Therefore, the highest performing duplex grades seek to maximize the content of chromium (Cr), molybdenum (Mo) and nitrogen (N).
