Haihao Group Ships ASME B16.9 ASTM A234 WPB Long Radius Elbows to Poland
Haihao Group has successfully completed the production and shipment of a large batch of ASME B16.9 ASTM A234 WPB elbows for a customer in Poland. The order was covering various sizes of 45-degree and 90-degree long radius elbows for industrial pipeline applications.
The supplied fittings are manufactured from ASTM A234 Grade WPB carbon steel and produced according to ASME B16.9 dimensional requirements. With a long radius design of R=1.5D (LR), these elbows provide smoother flow direction changes, lower pressure loss, and improved pipeline efficiency compared with short radius fittings.
This shipment includes both seamless and butt welded configurations, with sizes ranging from 1/2 inch to 24 inch and different wall thickness requirements to meet the customer’s engineering specifications.

| 90 Degree Long Radius Elbow | 1/2″ – 24″ | 3.73 – 24.61 mm | ASTM A234 WPB | ASME B16.9 |
| Seamless Butt Weld Elbow | 3/4″ – 12″ | SCH STD / SCH XS / SCH40 | ASTM A234 WPB | ASME B16.9 |
| Long Radius BW Elbow | 8″ – 24″ | 8.18 – 24.61 mm | ASTM A234 WPB | ASME B16.9 |
Manufacturing Features of ASME B16.9 WPB Elbows
The ASME B16.9 ASTM A234 WPB elbows supplied by Haihao Group are designed for demanding industrial piping systems where strength, dimensional accuracy, and weldability are critical.
ASTM A234 WPB is one of the most widely used carbon steel fitting materials for pressure piping. It offers good mechanical properties and excellent compatibility with carbon steel pipelines used in oil and gas, petrochemical, power generation, and general industrial projects.
During manufacturing, Haihao Group focuses on controlling the following key parameters:
- Precise elbow angle control for 45° and 90° configurations
- Accurate outside diameter and wall thickness
- Smooth internal and external surface condition
- Proper end bevel preparation for butt welding
- Heat treatment according to project requirements
- Dimensional inspection according to ASME B16.9
The long radius structure (1.5D LR) helps reduce turbulence and improves the stability of fluid transportation systems, making these fittings suitable for pipelines requiring efficient flow performance.
