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.

Basic features of stainless steel flange: it is composed of basic parameters, such as anchor bolt hole, raised face, connecting nozzle, core distance of anchor bolt hole, flange diameter, nominal size, nominal pressure, etc.

316 Stainless Steel Flange Dimensions differ from standard to standard. There are standards to cover short radius pipes and fittings as well as long radius pipes and fittings. There are different shapes and types of flanges. All flanges are made in a way to be connected with pipes and fittings with welding or by the tightening of bolts and nuts. There are differences in the number of bolt holes depending on the standards.

ASTM A403 WP304 Fittings are available in different sizes and shapes and have a pressure rating of 3000#, 6000#, and 9000#.

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.

Stainless steel 304l gets its name because of the interaction between its alloying composition and the environment to which they are exposed to resist rusting. Many types of stainless steel have multiple uses and there is a lot of overlap. All stainless steels contain at least 10% chromium. But not all stainless steels are created equal.

Heat treatment does not affect 254 Smo Stainless Steel Pipe they can only be hardened via cold reduction. SMO 254 Erw Tubes have a great influencing potential and ductility at ambient and sub-zero temperatures.

1.4539 plate, good oxidation resistance. However, the structural stability of this grade breaks down at high temperatures, especially above 400¡ãC. ASTM A240 UNS N08904 material can be solution heat treated at 1090-1175¡ãC followed by quenching. Heat treatment is suitable for hardening it. 1.4539 sheet is mainly used in oil refining equipment, pulp and paper processing industry, gas scrubbing plants, etc.

When selecting stainless steels that must withstand corrosive environments, austenitic stainless steels are often used.

The 304, 316 and 316L stainless steel formulations are austenitic, a term used to classify the crystal structure of the steel. The structure is achieved by heat treating at very high temperatures followed by quenching ¨C a rapid cooling process that locks the structural features in place. Austenitic formulations are stronger than martensitic or ferritic steels. Ferritic steels are magnetic, have low carbon content, and have poor corrosion resistance.

The main difference between 304 and 316 stainless steel is that the 316 grade has a much higher molybdenum content, typically 2-3% by weight, and provides better corrosion resistance.

The most basic difference between grade 304 and grade 316 stainless steels is that 316 tends to have more nickel and a bit of molybdenum in the mix. The general mechanical properties of the two metals are mostly comparable. The increased nickel content and the inclusion of molybdenum allows for grade 316 stainless steel to have better chemical resistance than 304 stainless steel. It¡¯s ability to resist acids and chlorides, including salt, makes grade 316 ideal for chemical processing and marine applications.

SAE 304 stainless steel is the most common stainless steel. The steel contains both chromium (between 18% and 20%) and nickel (between 8% and 10.5%)[1] metals as the main non-iron constituents. It is an austenitic stainless steel. It is less electrically and thermally conductive than carbon steel. It is magnetic, but less magnetic than steel. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes.[1]

Alloy 316H (UNS S31609) is a high carbon modification of Alloy 316 developed for high temperature service. This alloy has higher strength at elevated temperatures and can be used in structural and pressure vessel applications above 932¡ãF (500¡ãC). The higher carbon content of 316H also provides higher tensile and yield strengths than 316/316L, and its austenitic structure provides excellent toughness at low temperatures.

ASTM 182 is use in pressure systems, Included are flanges, fittings and similar parts to specified dimensions or to dimensional standards, such as the ASME specifications.

It is an austenitic stainless steel alloy with high nickel (24%), chromium (22%), molybdenum (6%), and nitrogen (0.18%) content and is commonly known as superaustenitic stainless steel (alloys such as 254 SMO (UNS?S31254) and 904L (UNS?N08904) also fall under the superaustenitic designation) while 2205 (UNS S32305/ S31803) and 2507 (UNS S32750) are duplex and super duplex stainless steel, respectively.

uns s30400 pipe fittings are used in petroleum, petrochemical, power plants and other general corrosion services.

Alloy 317L has excellent corrosion resistance in a wide range of chemicals. It resists attack in sulfuric acid, acidic chlorine and phosphoric acid.

304 stainless steel is the most common stainless steel. The steel contains both chromium (between 18% and 20%) and nickel (between 8% and 10.5%)[1] metals as the main non-iron constituents. It is an austenitic stainless steel.When it comes to uses, SS304 can be found in kitchen sinks and other appliances such as toasters and microwave ovens. SS304 is also used to make pressure vessels, wheel covers as well as for building facades.

Type 304L can be dual certified as 304 when the composition meets the lower carbon limit of 304L and a slightly higher 304 strength level. Type 304L should be specified for welding applications as the low carbon version eliminates chromium carbide precipitation and enhances corrosion resistance to the welded state.

Seamless piping is required for many high-pressure, high-temperature applications in the oil & gas, power generation and pharmaceutical industries. Welded piping (which is generally cheaper to produce and is more widely available) is specified across all industries as long as the temperature, pressure and other service variables do not exceed parameters noted in the applicable standard.

304L stainless steel pipe is a low carbon variant of grade 304 – the steel can be welded without problems with carbon precipitation (the precipitation of chromium carbide when heat is applied during welding depletes the steel of chromium, reducing its resistance to -corrosion/oxidation Effect).

Stainless steel is an alloy of iron that is resistant to rusting. 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.
A stainless steel pipe system is the product of choice for carrying corrosive or sanitary fluids, slurries and gases, particularly where high pressures, high temperatures or corrosive environments are involved. As a result of the aesthetic properties of stainless steel, pipe is often use in architectural applications.

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.
