Haihao Group Ships ASTM A234 WPB Seamless Pipe Fittings to South Korea
A complete range of carbon steel butt-weld fittings manufactured to ASME B16.9 has recently been prepared by Haihao Group for a customer in South Korea. The order includes 90-degree long radius elbows, seamless caps, equal and reducing tees, and concentric and eccentric reducers. All products are specified in ASTM A234 WPB material with SCH 40 wall thickness.
Rather than focusing on a single fitting type, this order brings together multiple components used in industrial piping systems. The different sizes and configurations allow the customer to source several essential pipeline connections within one procurement package.
A Range of Seamless Fittings for Different Piping Connections
The order covers four main product categories, each serving a different function in pipeline installation.
90-Degree Long Radius Elbows
The largest product group consists of seamless 90-degree long radius elbows in ASTM A234 WPB material. The supplied sizes range from 3/4 inch to 10 inches, all with SCH 40 wall thickness.
These elbows are designed to change pipeline direction while providing a long-radius flow path. They are commonly used in industrial piping layouts where directional changes and connection geometry need to be considered together.
The order includes multiple sizes of 2-inch, 4-inch, and 6-inch elbows, as well as 3/4-inch, 1-inch, 8-inch, and 10-inch configurations.
Seamless Pipe Cap
The shipment also includes 6-inch seamless pipe caps in ASTM A234 WPB, SCH 40.
A pipe cap is used to close the end of a pipeline or piping component. Its dimensions, material, and wall thickness need to correspond to the connected piping specification.
Equal and Reducing Tees
The tee products cover a variety of main-run and branch combinations, including:
- Equal tees: 2″, 4″, 6″, 10″
- Reducing tees: 2″ × 1″, 4″ × 2″, 6″ × 2″, 8″ × 2″, 8″ × 4″, and 10″ × 6″
These configurations serve different branch connection requirements. Equal tees maintain the same nominal diameter at the run and branch, while reducing tees provide a smaller branch outlet.
For this order, selected tee items also carry additional surface preparation and inspection requirements, including sandblasting and magnetic particle testing (MT), as specified in the purchase requirements.
Concentric and Eccentric Reducers
The reducer section includes both concentric and eccentric designs.
The concentric reducers cover 3″ × 2″, 4″ × 2″, 4″ × 3″, 6″ × 3″, 6″ × 4″, 8″ × 6″, and 10″ × 8″ sizes.
The eccentric reducer configurations include 4″ × 3″ and 6″ × 4″.
A concentric reducer maintains a common centerline between the two ends, whereas an eccentric reducer has an offset centerline. The choice between them depends on pipeline arrangement, installation orientation, and project requirements.
ASTM A234 WPB seamless butt weld pipe fittings for South Korean customer
ASTM A234 WPB Material and ASME B16.9 Manufacturing Standard
Material and dimensional specifications are important considerations when sourcing seamless butt-weld fittings.
ASTM A234 WPB is a commonly specified carbon steel grade for wrought pipe fittings used in pressure piping applications. ASME B16.9 establishes dimensional and tolerance requirements for factory-made wrought butt-welding fittings.
For this Korean order, the material and manufacturing requirements are consistent across the different product categories:
| Specification | Order Requirement |
|---|---|
| Material | ASTM A234 WPB |
| Manufacturing standard | ASME B16.9 |
| Construction | Seamless |
| Wall thickness | SCH 40 |
| Elbow configuration | 90° Long Radius |
| Tee configurations | Equal and Reducing |
| Reducer configurations | Concentric and Eccentric |
| Additional requirements | Sandblasting and MT for designated tee items |
Sandblasting and Magnetic Particle Testing for Selected Tees
In addition to the basic manufacturing requirements, the purchase order identifies sandblasting and magnetic particle testing for designated tee products.
Sandblasting is used to remove surface contaminants, scale, and other unwanted residues, providing a cleaner surface for subsequent handling or coating operations.
Magnetic particle testing is a non-destructive examination method used to identify surface and near-surface discontinuities in suitable ferromagnetic materials. For carbon steel fittings such as ASTM A234 WPB, MT can be applied where specified by the customer’s inspection requirements.
These operations serve different purposes: one addresses surface preparation, while the other examines material integrity. Keeping the requirements clear during production helps ensure that the designated fittings receive the specified treatment and inspection.
Haihao Group Supplies Seamless Butt-Weld Pipe Fittings Worldwide
Haihao Group manufactures and supplies carbon steel, alloy steel, and stainless steel pipe fittings for industrial piping projects in different markets.
Its product range includes long radius and short radius elbows, equal and reducing tees, concentric and eccentric reducers, caps, and other butt-weld components.
For customers looking for ASTM A234 WPB fittings, the company can review requirements involving product type, nominal size, wall thickness, applicable standards, and additional inspection needs.
The completed order for South Korea reflects the importance of coordinating a varied fitting package rather than treating each component as an isolated purchase.
