Calculation Formula : W=0.0387 * S( D – S ) * R / 1000
· W = Weight (kg/piece).
· S = Thickness in mm.
· D = Nominal Diameter in mm.
· R = Radius
For example” 90 Degree Elbow SR 10″ x 10mm Thickness BW ASTM A403 WP316 ASME B16.9″
From above information, we can know OD is 10″ which is 273mm. SR means 1D that is 1 x 273mm. Thickness is 10mm. Let’s take these data into formula.
0.0387 x 10 x (273 – 10) x 1 x 273 / 1000 = 27.8kg/pcs.
Package
We marked Duplex Steel Buttweld Fittings with Grade, Heat No, Size, Standard and Thickness. Our workers wrapped ASTM A815 UNS S31803 Elbow with water-proof material, and put them into wooden case or pallets, then bundled packages with nylon rope.
Clear labels are tagged on the outside of the package for easy identification of the quantity and product I.D. great care is taken during operation and transportation.
Inspection
1. Visual the surface of duplex stainless Steel Elbow fittings.
2. Check the marking. Such as size, material code, grade, thickness, heat No.
3. Measure the diameter and thickness whether in tolerance.
4. Test the chemical properties of ASTM A815 UNS S31803 Pipe Fittings.
Features
Duplex stainless steels are considered resistant to stress corrosion cracking, they are not as resistant to this form of attack as ferritic stainless steels. However, the corrosion resistance of the least resistant duplex stainless steels is much better than most commonly used grades of stainless steels 304 and 316.
