Haihao Group Delivers ASTM A234 WPB Seamless Long Radius Elbows for an Industrial Project in India
Haihao Group has recently completed the production and shipment of a batch of ASTM A234 WPB seamless elbows for a valued customer in India. The order includes DN600 45° Long Radius (LR) Elbows and DN600 90° Long Radius (LR) Elbows, both manufactured with SCH40 wall thickness using high-quality ASTM A234 WPB carbon steel.
As one of the world’s leading manufacturers of industrial pipe fittings, Haihao Group follows strict production and inspection procedures to ensure every fitting meets customer specifications and international standards. This shipment reflects our capability to supply reliable large-diameter pipeline components for oil & gas, petrochemical, power generation, and infrastructure projects.
Shipment Overview
The products supplied for this Indian project are summarized below:
| Product | Size | Wall Thickness | Material |
| 45° Seamless Long Radius Elbow | DN600 | SCH40 | ASTM A234 WPB |
| 90° Seamless Long Radius Elbow | DN600 | SCH40 | ASTM A234 WPB |
High-Quality ASTM A234 WPB Seamless Elbows
The main product in this shipment is the ASTM A234 WPB seamless elbow, which is widely used in medium- and high-pressure piping systems because of its excellent mechanical strength, weldability, and long service life.
Compared with welded fittings, seamless elbows provide a more uniform wall structure and enhanced pressure resistance, making them an ideal choice for critical industrial applications. Every ASTM A234 WPB seamless elbow produced by Haihao Group is manufactured under carefully controlled forming and heat treatment processes to achieve consistent dimensions and dependable performance.
For large-diameter piping systems such as DN600, maintaining precise curvature and wall thickness is essential for efficient installation and smooth fluid flow. Haihao Group’s production team pays close attention to every manufacturing step to ensure each ASTM A234 WPB seamless elbow fully satisfies customer requirements.

Strict Quality Control from Material to Delivery
Quality assurance is an integral part of Haihao Group’s manufacturing process. Before shipment, every fitting undergoes comprehensive inspections to verify compliance with project specifications.
The quality control process includes:
- Raw material verification for ASTM A234 WPB
- Dimensional inspection of diameter, wall thickness, and center-to-end distance
- Visual surface examination
- Forming quality inspection
- Mechanical property verification
- Identification and traceability management
- Final packaging inspection before export
This systematic inspection procedure ensures every ASTM A234 WPB seamless elbow delivered to the customer is ready for safe and reliable installation.
Applications of Large-Diameter Seamless Elbows
The supplied DN600 elbows are suitable for a wide range of industrial pipeline systems where strength and durability are essential.
Typical applications include:
- Oil and gas transmission pipelines
- Petrochemical processing plants
- Thermal and nuclear power stations
- Water transmission projects
- Industrial process piping
- Offshore and onshore energy facilities
The 45° LR elbow is commonly used where gradual flow direction changes are required, while the 90° LR elbow provides efficient directional changes with lower pressure loss than short-radius designs.
