Haihao Group Supplies ASME B16.9 A234 WPB and BS EN 10253-2 P265GH Tee Fittings to UK Customer
Haihao Group recently completed the production and delivery of a large batch of carbon steel tee fittings for a customer in the United Kingdom. The shipment included both ASME B16.9 A234 WPB reducing tee products and BS EN 10253-2 P265GH tee fitting products, covering a wide range of sizes for industrial piping systems.
The order involved equal tees and reducing tees manufactured according to international standards, with special requirements for bevel preparation, surface treatment, and dimensional inspection. All products were supplied with full traceability and underwent strict quality control before shipment.
Project Overview
The order included two major categories of tee fittings manufactured according to different international standards.
ASME B16.9 A234 WPB Reducing Tee for Industrial Piping Systems
A significant portion of the shipment consisted of ASME B16.9 A234 WPB reducing tee fittings. These fittings are widely used in oil & gas, power generation, water treatment, and industrial processing facilities.
ASTM A234 WPB is one of the most commonly specified carbon steel materials for butt-weld fittings because it offers:
- Excellent weldability
- Reliable mechanical strength
- Good pressure resistance
- Cost-effective performance
- Broad international acceptance
The supplied fittings ranged from standard equal tees to customized reducing tees designed to connect pipelines of different diameters while maintaining smooth flow distribution.

BS EN 10253-2 P265GH Tee Fittings for European Projects
The shipment also included a large quantity of BS EN 10253-2 P265GH tee fitting products manufactured for European-standard piping systems.
P265GH is a pressure vessel quality carbon steel widely used in:
- Steam systems
- Heating networks
- Industrial plants
- Process piping installations
- Utility infrastructure
Compared with conventional structural grades, P265GH offers excellent performance under elevated temperatures and pressure conditions.
The delivered BS EN 10253-2 P265GH tee fitting products were manufactured in multiple sizes, including 1½”, 3″, 4″, 5″, 6″, and 10″ branch configurations.
Strict Surface Preparation and Bevel Requirements
To meet the customer’s installation requirements, all tee fittings underwent surface treatment and end preparation before shipment.
Surface Treatment
For P265GH fittings:
- Sandblasted surface
- Bright beveled ends
- Anti-rust oil protection
For ASTM A234 WPB fittings:
- Black painted finish
- Export-ready protection
Precision Bevel Machining
The project required compliance with two different bevel standards:
BS EN 10253-2 Bevel Requirements
- Bevel angle: 30° (+5°)
- Root face included
- Dimensional acceptance according to EN requirements
ASME B16.9 Bevel Requirements
- Bevel angle: 37.5° ± 2.5°
- Root face included
- Full compliance with ASME dimensional tolerances
These details help ensure proper field welding and reliable long-term performance.
Why Tee Fittings Are Critical in Pipeline Systems
Tee fittings play a key role in modern piping networks because they allow branch connections while maintaining efficient flow control.
Equal Tee Applications
Equal tees are commonly used where branch and run pipe sizes are identical.
Typical applications include:
- Utility systems
- Water distribution
- Process piping
- Fire protection networks
Reducing Tee Applications
Reducing tees allow branch connections with smaller outlet diameters.
They are widely used in:
- Refinery piping systems
- Petrochemical plants
- District heating projects
- Industrial process lines
Both equal and reducing tees contribute to flexible pipeline design and efficient fluid distribution.
Quality Assurance Throughout Manufacturing
Haihao Group applies strict quality control procedures during production.
Inspection activities included:
Raw Material Verification
All materials were checked against ASTM A234 WPB and P265GH requirements.
Dimensional Inspection
Every fitting was inspected according to ASME B16.9 or BS EN 10253-2 standards.
Surface Examination
Visual inspection was conducted after blasting, painting, and oil coating.
Bevel Inspection
Each fitting’s bevel geometry was verified to meet project specifications.
Final Shipment Inspection
Products were inspected before packaging to ensure full compliance with customer requirements.
Applications of Carbon Steel Tee Fittings
The supplied ASME B16.9 A234 WPB reducing tee and BS EN 10253-2 P265GH tee fitting products are commonly used in:

FAQ
What is ASTM A234 WPB used for?
ASTM A234 WPB is commonly used for carbon steel butt-weld fittings in pressure piping systems.
What is the difference between equal tees and reducing tees?
An equal tee has the same diameter for all outlets, while a reducing tee has a smaller branch connection.
Why is P265GH widely used in Europe?
P265GH is a pressure vessel steel grade with excellent mechanical properties and good performance at elevated temperatures.
What bevel angle is required by ASME B16.9?
ASME B16.9 typically specifies a bevel angle of 37.5° ± 2.5° with a root face.
Can Haihao Group manufacture custom tee fittings?
Yes. Haihao Group can produce tee fittings according to ASME, EN, DIN, GOST, and customer-specific requirements.
