Mangalam Metal is Supplier of Inconel 800 / 800H / 800HT Pipes and Tubes, which is used in the chemical processing industry. Inconel 800 Seamless Pipes has as its main characteristic as the great addition of molybdenum to its chemical composition, which guarantees an increased resistance to chemical attack when compared with chromium-nickel-molybdenum austenitic steels. Inconel 800H Welded Tubes has higher molybdenum or molybdenum plus nitrogen content which provide even greater resistance to pitting, crevice corrosion and general corrosion are also available in flat-rolled products. Inconel 800HT EFW Pipes is commonly used to handle sulfur, pulp liquor, acid dyestuffs, acetylating and nitrating mixtures, bleaching solutions, severe coal and oil, and many chemical compounds.
Inconel 800 ERW Tubes is resistant to sulfuric acid concentrations up to 5 percent at temperatures as high as 120 Degree F (49 Degree C). Low speeds and constant feeds will minimize the tendency of Inconel 800H Round Pipes to work harden. In addition to excellent corrosion resistance and strength properties, Inconel 800HT Square Tubes also provide the excellent fabricability and formability which are typical of the austenitic alloys. Inconel 800 Rectangular Pipes is tougher with a long stringy chip; however, using chip breakers is recommended. Inconel 800H Electropolish Tubes can be welded using fusion and resistance methods, and has improved resistance to chlorides and other corrosives.
