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.

What is Formula of 90 Degree LR Elbow Weight
The weight formula is W=0.0387 * S*(D – S) * R / 1000, the unit is kg/piece. What’s the meaning of each letter? Let’s explain to you.
- W means Weight.
- S means Thickness in mm.
- D means Outside Diameter in mm.
- R means Radius that LR=1.5D, SR=1D.
Now we take “ASTM B366 Incoloy 825 Seamless 90 Degree LR Elbow DN150 SCH80S” as sample. From above diameter and thickness chart, we know the outside diameter is 168.3mm and thickness is 10.97mm. The weight will be 0.0387 x 10.97 x ( 168.3 – 10.97 )x 1.5 x 168.3 / 1000 = 16.861kg/piece.
What is Export Package for Pipe Fittings?
- Blasting and Painting on pipe fittings.
- Wrapping them with plastic foam.
- Packing them into wooden case or pallet.
- Stick shipping mark on the outside of wooden case.
