The material provides stable welding performance during fabrication and installation.
Strong Mechanical Performance
P265GH reducers maintain long-term reliability in industrial operating environments.
Compliance with European Standards
BS EN 10253-2 fittings are commonly specified in European energy and industrial projects.
Haihao Group manufactures BS EN 10253-2 P265GH concentric reducers for pressure piping systems with strict dimensional and material quality control.
ASME B16.9 A234 WPB Reducers for Pipeline Construction
The shipment also included multiple ASME B16.9 A234 WPB eccentric reducers for industrial pipelines, widely used in global piping systems.
ASTM A234 WPB is one of the most commonly used carbon steel materials for butt weld fittings because of its balanced strength, weldability, and cost efficiency.
Benefits of A234 WPB Reducers
Wide Industrial Application
Suitable for:
- Oil & gas projects
- Petrochemical facilities
- Power plants
- Water treatment systems
- Marine engineering
Good Fabrication Performance
Easy to weld, process, and install.
Cost-Effective Pipeline Solution
Provides dependable mechanical properties at competitive cost.
The supplied ASME reducers were coated with black paint for corrosion protection during transportation and storage.
Difference Between Concentric and Eccentric Reducers
Haihao Group supplied both concentric and eccentric reducers to meet different pipeline engineering requirements.
Concentric Reducers
Concentric reducers maintain a common centerline between large and small pipe ends. They are commonly used in vertical piping systems and general process pipelines.
Eccentric Reducers
Eccentric reducers have an offset centerline and are widely used in horizontal pipelines to prevent air accumulation or liquid pooling.
Haihao Group can manufacture:
- Seamless reducers
- Welded reducers
- Concentric reducers
- Eccentric reducers
- Customized reducer fittings
Surface Protection for Export Reducers
Different surface treatments were applied according to customer project requirements.
Anti-Rust Oil Coating
Used for P265GH reducers to protect against moisture and corrosion during export transportation.
Black Paint Coating
Applied to ASTM A234 WPB reducers to improve corrosion resistance and storage protection.
Haihao Group can also provide:
- Hot-dip galvanizing
- Epoxy coating
- Sandblasting
- Customer-specified surface treatment
Strict Inspection and Quality Assurance
Haihao Group follows comprehensive quality inspection procedures throughout production.
Inspection Procedures Include
- Raw material verification
- Dimensional inspection
- Wall thickness testing
- Bevel inspection
- Surface quality inspection
- Standard compliance verification
Every batch of BS EN 10253-2 P265GH concentric reducers for pressure piping systems is carefully inspected before shipment.
