Rajendra Pipe Fittings is a prominent manufacturer, supplier, and distributor of Alloy 20 Seamless Pipes. Alloy 20 Seamless Pipes is made from a combination of nickel-iron-chromium along with copper and molybdenum. It offers excellent resistance to general corrosion, crevice corrosion and pitting in chemicals. Alloy 20 Seamless Pipes UNS N08020 also well-known as Carpenter 20 which is an austenitic which provide resistance to pitting, crevice corrosion, and hostile environments. These Alloy 20 Seamless Pipes UNS N08020 is used in the applications involving acid attack, specifically sulfuric acid. This alloy is specifically designed to withstand sulfuric acid and offers excellent corrosion resistance. The Alloy UNS N08020 Seamless Pipes are available in size ranges of ½ NB to 8 NB and wall range of 0.095″ – 1.000″ as well as 1.250″ – 6.000″ outer diameter. Alloy 20 pipes are commonly referred to as UNS N08020 and they are high alloy stainless steel with excellent resistant to chloride stress corrosion cracking and sulfuric acid. This alloy is having chromium, nickel, copper, molybdenum that altogether helps in giving an excellent corrosion resistant. Due to being good resistance to crevice corrosion and pitting stainless steel, the alloy is used in manufacturing heat exchangers, tanks, pickling equipment and process piping. The temperature for hot work is 2100-2250˚F followed by water quench. These pipes are available in different forms like Round Pipes/Tubes, Square Pipes/Tubes, rectangular pipes/tubes, Coiled Tubes, “U” shape, pan cake coils and hydraulic tubes. The ends of these alloy 20 pipes are designed in plain end, beveled end and treaded end.
At Rajendra Pipe Fittings we put our products into stringent testing to ensure the high quality. Some of the tests are chemical analysis, flaring test, mechanical test, flattening test, radiographic test, PMI test, micro and macro test, pitting resistance test and so on. We are concerned about our customer’s satisfaction hence keeping a close eye on the services we provide. We are engaged in providing the best services to our valued customers at Rajendra Pipe Fittings. Our team strives hard to manufacture and maintain the high quality standards of our products to meet both national and international standards.
