Acid-resistant flanges - general information

Stainlesseurope.com store is engaged in selling acid-resistant flanges for companies and private persons. High quality of offered flanges and wide range of sizes puts it ahead of Polish stainless and acid-resistant steel distributors. Our acid-resistant flanges are made of very good steel quality, therefore they are valued around the world. The described fittings are made according to standard ISO 9001 thus it is possible to use them at locations limited with special material requirements.

Application of acid-resistant flanges

Acid-resistant flanges in our warehouse are used in shipbuilding sector, power engineering, bio-engineering, during natural gas mining and in petroleum and petrochemical industry. Acid-resistant flanges are also used in medicine, civil engineering and in processing food products and sewage treatment sector. The offered assortment of acid-resistant fittings, because of the high demand and wide range of application, is distributed to almost all countries of the European Union and outside its borders. Usually, acid-resistant flanges are used at energy producing plants, at companies mining oil and in pipelines transporting water for households, company buildings, hospitals, schools and many more. Universal application of acid-resistant flanges made the offer of stainlesseurope store to include the following flanges: acid-resistant plugging flanges, acid-resistant neck flanges, acid-resistant flat flanges, acid-resistant threaded flanges, acid-resistant flanges with stub pipe and loose flanges with flat ring for welding.

Acid-resistant flanges grades available in stock

Flat flanges in grade 1.4404 / 316L belong to austenitic steel group. Their chemical composition include elements providing resistance to corrosion such as nickel, molybdenum and chromium. Acid-resistant flanges 1.4404 show lack of magnetism under soft condition and characterize with good weldability. The 316L grade fittings is designed for acidic and basic environments. The 1.4404 acid-resistant flanges are used in pertroleum, medical, automotive, petrochemical and pharmaceutical industry for construction of pipelines and machines.

Flat flanges of grade 1.4541 / 321 are also considered to be austenitic steels. These flanges manifest great resistance to corrosion. The 321 flanges are not susceptible to crevice corrosion and high temperatures. Acid-resistant flanges of this grade can be welded. They are used in pharmaceutical and chemical industry as well as in food processing. The 321 stainless steel flanges are also used for construction of pipelines in petroleum and petrochemical plants.
