- OD 88.9 mm | DN 80 | Thickness 3.05 mm
- OD 88.9 mm | DN 80 | Thickness 5.49 mm
- OD 141.3 mm | DN 125 | Thickness 6.55 mm
These ASTM A234 seamless elbows are commonly used in carbon steel piping systems requiring smooth flow and reduced pressure loss.
Seamless 90 Degree Short Radius Elbow (ASTM A234)
- OD 219.1 mm | DN 200 | Thickness 8.18 mm
Short radius elbows are suitable for installations with limited space while maintaining reliable mechanical strength.
Seamless Stainless Steel Elbows (ASTM A403 316L)
- OD 21.3 mm | DN 15 | Thickness 2.77 mm | SCH 40
- OD 48.3 mm | DN 40 | Thickness 3.68 mm | SCH 40
- OD 73.0 mm | DN 65 | Thickness 2.11 mm | SCH 5
- OD 219.1 mm | DN 200 | Thickness 2.77 mm | SCH 5
ASTM A403 316L seamless elbows provide excellent corrosion resistance and are widely used in chemical, food, and marine-related piping systems.
Seamless Concentric Reducers
Stainless Steel (ASTM A403 316L)
- OD 219.1 → 168.3 mm | DN 200 → DN 150 | Thickness 3.76 mm | SCH 10
Carbon Steel (ASTM A234)
- OD 48.3 → 42.2 mm | DN 40 → DN 32 | Thickness 3.68 / 3.56 mm
These seamless concentric reducers ensure smooth diameter transitions and consistent flow characteristics.
EN 10253-2 Pipe Cap
- OD 48.3 mm | DN 40 | Thickness 5.0 mm
- Standard: EN 10253-2
- Material: ASTM A234
Pipe caps are used to safely close pipeline ends and protect systems during operation or maintenance.
