AL6XN is primarily used for its improved pitting and crevice corrosion resistance in chlorides. It is a formable and weldable stainless steel.

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.

316 Stainless Steel’s resistance to corrosion and contamination, low maintenance, and a familiar luster make stainless steel an ideal material for many applications that require the strength and corrosion resistance of steel. In addition, stainless steel can be rolled into sheet, plate, bar, wire and tube. These can be used in cookware, tableware, surgical instruments, major appliances, vehicles, construction materials in large buildings, industrial equipment (eg, paper mills, chemical plants, water treatment), and storage tanks and tankers for chemicals and food.

In order to convey the pipeline, it is necessary to remove the straight hose in the pipeline. When using various pipelines, various pipelines must be used. When the pipeline is used, the elbow must be used to change the size of the pipeline. When bifurcating, the three-way pipe The flange connection used when the joint is used with various pipe joints, in order to reach the long-distance transmission pipeline, in order to reach the thermal expansion and cold contraction joint or effective connection aging of the pipeline, the long-distance expansion and cold contraction joint is used for the connection of the pipeline. , In the connection of various instruments, there are also the connectors and plugs of the instrument phase.

The grade is non-magnetic in all conditions and has excellent formability and weldability. The austenitic structure also gives this grade excellent toughness, even down to cryogenic temperatures.

The 316 stainless steel reducer is good to be used in water, marine and sea water applications to reduce the size of a pipe line. The ASTM A403 Grade wp316 tee is used to divide or connect two pipes with another pipe. The 316 grade of steel is also used for fittings in food grade applications. The ASME SA 403 WP 316 Pipe Cap is a unique type of fitting in that it closes a pipeline rather than connecting two parts together.

Steel pipes can be disintegrated on the basis of its application. Typical applications of steel pipes are in the area of water pipelines, industrial water lines, oil pipe lines, cross country pipe line,agriculture and irrigation pipes, tube lines for natural gas, chemical industries, automobile industry, construction industries and other purposes.

Greater strength and corrosion resistance still mandate the use of seamless stainless steel and nickel alloy tubing for high pressure applications within the oil and gas, petrochemical, chemical, energy, and pulp and paper industries.

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).

The high alloying of the material is giving 904L chloride stress corrosion cracking resistance but still, the material is susceptible.

Alloy steel A182 F5 grade WNRF flanges have welded necks for added strength and grip. These can be used under high pressure gas and liquid flows as they are leak proof. They can also be used at very high and very low temperatures, as the welded neck can greatly reduce leakage. Raised faces provide great grip for bolting or welding.

Stainless steel Grade 254 SMO Flanges is quite tough to machine due to the extremely high work hardening rate and lack of sulfur content; however using sharp tools, overpowered machine tools, positive feeds, good amount of lubrication, and slow speeds tend to provide good machining results.

Stainless Steel B366 WP904L contains higher chromium and low carbon content.Our SS 904L Elbow have resistance to atmospheric corrosion and serve general purposes like sealing pipe ends and preventing any contamination to the internal fluids.

316L stainless steel is an ultra-low carbon version of 316 stainless steel that helps avoid carbide precipitation from welding. Grade 316 stainless steel has a lower chromium content¡ªtypically around 16%¡ªbut increases the nickel content and adds molybdenum to the mix.

Good ductility and thermal conductivity Ideal for seawater 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]

In general, the Type 316 grade can be considered equally good in a given environment. A notable exception is intergranular corrosion in the heat-affected zone on welds and susceptible alloys in sufficiently corrosive environments. In such media, Type 316L is more suitable for welding conditions than Type 316 because the low carbon content increases resistance to intergranular corrosion.

Precipitation hardening martensitic stainless steels have comparable corrosion resistance to austenitic grades, but can be precipitation hardened to higher strengths than other martensitic grades. The most common 17-4PH uses about 17% chromium and 4% nickel. The Lockheed-Martin Joint Strike Fighter was the first aircraft to use precipitation-hardenable stainless steel Carpenter Custom 465 in its fuselage.

ASTM a403 wp304L elbows are installed between two lengths of pipe to allow for a change of direction. Usually available with 90¡ã or 45¡ã elbows, 90¡ã elbows are also known as “90 bends”, “90 ell” or “quarter bends”, and 45¡ã elbows are also known as “45 bends” or “45 ells” Elbows are also classified by length. Long radius elbows have a radius of curvature that is 1.5 times the pipe diameter, while short radius elbows have a radius equal to the pipe diameter. ASTM A403 WP304L is the most versatile and versatile of the stainless steel family alloy, ideal for a variety of commercial and domestic 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.
