Haihao Group Ships ASTM A234 WPB Seamless 90 Degree Elbows to Vietnam for Pipeline Project
Haihao Group has recently completed the production and shipment of ASTM A234 WPB seamless 90 degree elbows for a valued customer in Vietnam. The order includes both long radius (LR) elbows and short radius (SR) elbows, designed for use in industrial pipeline systems.
Manufactured from ASTM A234 WPB carbon steel, these seamless pipe elbows offer excellent mechanical strength, reliable performance, and strong durability for pipeline connections in various industrial environments.
The products were carefully inspected, coated with anti-rust oil, and packed securely before shipment to ensure safe delivery and long-term protection during transportation.
ASTM A234 WPB seamless 90 degree pipe elbows ready for shipment
Order Overview
The shipment includes multiple sizes of seamless 90° elbows, covering small to medium pipeline diameters used in industrial piping systems.
Product Type: Seamless 90 Degree Pipe Elbow
Material: ASTM A234 WPB
Surface Protection: Anti-rust oil coating
Elbow Types:
- Long Radius 90° Elbow (LR)
- Short Radius 90° Elbow (SR)
Long Radius Seamless 90 Degree Elbows
Several sizes of ASTM A234 WPB long radius elbows were supplied for the project, including:
- DN15 (OD 21.3 mm)
- DN20 (OD 26.7 mm, including SCH80 thickness)
- DN25 (OD 33.4 mm)
- DN32 (OD 42.2 mm)
- DN40 (OD 48.3 mm, including SCH160)
- DN50 (OD 60.3 mm)
- DN65 (OD 73 mm)
- DN80 (OD 88.9 mm)
- DN100 (OD 114.3 mm)
Long radius elbows are widely used in pipeline systems because they provide smoother flow direction changes and lower pressure loss.
Short Radius Seamless 90 Degree Elbows
The shipment also includes short radius elbows, commonly used in pipeline systems where space is limited.
Typical sizes include:
- DN25 (OD 33.4 mm)
- DN32 (OD 42.2 mm)
- DN40 (OD 48.3 mm)
- DN50 (OD 60.3 mm)
- DN65 (OD 73 mm)
These short radius 90 degree pipe elbows are suitable for compact piping layouts while maintaining reliable performance.
