What is Incoloy 825

Designated as UNS N08825 or DIN W.Nr. 2.4858, Incoloy 825 (also known as “Alloy 825”) is an iron-nickel-chromium alloy with additions of molybdenum, cooper and titanium. The molybdenum addition improves its resistance to pitting corrosion in aqueous corrosion application while copper content bestows resistance to sulfuric acid. Titanium is added for stabilization. The Alloy 825 has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion. It is especially resistant to sulfuric and phosphoric acids. Incoloy 825 alloy is mainly used for chemical processing, petrochemical piping, pollution-control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production, and pickling equipment.

2)Length E applies for the thickness not exceeding the Limiting Wall Thickness, Length E1 applies for the thickness exceeding the Limiting Wall Thickness.For the caps with DN ≥650 (NPS26), they will be made subject to the sizes agreed between purchaser and manufacturer or be supplied according to manufacturer’s size.

What is Formula of Pipe cap Weight

20210603231814 75157 - ASME B16.9 ASTM B366 Incoloy 825 Pipe Cap DN250 SCH100

Weight of a Butt Weld Cap as per ASME B16.9 is calculated as per following formula  :

  20210603234515 65061 - ASME B16.9 ASTM B366 Incoloy 825 Pipe Cap DN250 SCH100

Where :

  • W = Weight of Cap in Kg.

  • OD = Outside diameter of cap (mm)

  • E = End to end length of cap (mm)

  • T = Wall Thickness (mm)

Dimension and Weight of Caps

All dimensions are in “mm” unless noted otherwise.
All weights are in “kg”.
Cap dimensions are as per ASME B16.9.
