Project Overview: Large Diameter Seamless Tee Fittings for India
The customer required heavy-duty tee fittings with seamless construction to ensure stable performance during pipeline operation. The supplied products include:
| Product | Size | Wall Thickness | Material | Inspection & Surface Treatment |
| Seamless Equal Tee | DN600 | SCH40 | ASTM A234 WPB | Sand Blasting, Magnetic Particle Testing |
| Seamless Reducing Tee | DN600 × DN200 | SCH40 | ASTM A234 WPB | Sand Blasting, Magnetic Particle Testing |
Reliable Performance of ASTM A234 WPB Seamless Tee Fittings
For this project, Haihao Group selected ASTM A234 WPB seamless tee fittings due to their excellent mechanical properties and wide application in industrial piping systems.
ASTM A234 WPB is a commonly used carbon steel fitting material for pressure piping applications. It offers a good balance of strength, weldability, and durability, making it suitable for industries such as oil and gas, power generation, chemical processing, and water transportation.
The ASTM A234 WPB seamless tee fittings supplied for this project were manufactured with strict control of dimensions, material traceability, and surface condition. The seamless manufacturing process helps improve structural consistency, especially for large-size fittings operating under pressure.
Manufacturing Process and Quality Inspection
Producing DN600 large-diameter tees requires precise forming technology and strict quality management. Haihao Group controls every stage from raw material verification to final inspection.
The main manufacturing and inspection procedures include:
- Raw material inspection:Confirming chemical composition and mechanical properties of ASTM A234 WPB material.
- Seamless forming process:Ensuring uniform wall thickness and accurate geometry.
- Dimensional inspection:Checking outside diameter, branch size, wall thickness, and overall dimensions.
- Sand blasting treatment:Removing surface impurities and preparing the fittings for further coating or installation.
- Magnetic particle testing (MT):Detecting possible surface defects and improving reliability.
For large-size pipeline components, inspection quality is especially important. The combination of manufacturing experience and testing procedures enables Haihao Group to deliver dependable ASTM A234 WPB seamless tee fittings for international projects.
Applications of DN600 Carbon Steel Tee Fittings
Large diameter tee fittings are widely used for pipeline branching and flow distribution systems. The DN600 equal tee and DN600×DN200 reducing tee supplied in this order can be applied in:
- Oil and gas transmission pipelines
- Refinery and petrochemical facilities
- Power plant piping systems
- Industrial water pipelines
- Large-scale infrastructure projects
The reducing tee design allows pipeline size transition while maintaining efficient flow distribution, while the equal tee provides a direct branch connection for the same diameter pipeline.
