ASTM A182 F316L Slip On Flange
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.

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.

The molybdenum gives SS 316 better overall corrosion resistant properties than Stainless Steel 304, particularly higher resistance to pitting and crevice corrosion in chloride environments.

Stainless steel flanges are often used for the installation of various pipelines, especially large and long distance metal transmission pipelines. Flanges are used for long-term pipelines.

Though 310 is ideal for high temperature use, it should not be exposed to the severe thermal shock of repeated liquid quenching or where aqueous corrosive contaminants are present.

The high chromium and moderate nickel content of 310S stainless steel allow these steels to be used in H2S-containing reduced sulfur atmospheres. They are widely used in moderate carburizing atmospheres, such as those encountered in petrochemical environments. For more severe carburizing atmospheres, other heat-resistant alloys should be selected. Grade 310 is not recommended for frequent liquid quenching due to thermal shock. Due to its toughness and low magnetic permeability, this grade is often used in low temperature applications.

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.

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]

304 stainless steel has excellent resistance to a wide range of atmospheric environments and many corrosive media. It will experience pitting and crevice corrosion in warm chloride environments, and stress corrosion cracking above about 60 ¡ãC. It is considered to be resistant to pitting corrosion in water up to about 400 mg/L chloride at ambient temperature, decreasing to about 150 mg/L at 60 ¡ãC.

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.

After tension testing and three-dimensional vibration test, the tearing of the sewn stainless steel pipe occurs almost far away from the welding point or the heated area. This is because the weld less impurities and nitrogen content is slightly higher, so the strength of the weld better than other parts.

Grade F22 is a low alloy steel grade with a chromium content between 2% and 2.5%. The content of chromium and molybdenum is twice that of F11 grade. However, due to the maximum content of all alloying elements up to 5%, it is classified as a low alloy steel grade. As a low alloy steel grade, ASTM A182 F22 flanges outperform carbon steel, especially in applications involving high temperatures.
