Haihao Group delivers ASME B16.9 45° and 90° long radius, short radius elbows for Belarusian client
Haihao Group has recently completed an important order for a Belarusian client, manufacturing a range of ASME B16.9 45° and 90° long radius elbows, short radius elbows, and fittings. These components are made from high-quality materials, including ASTM A234 WP5, ASTM A234 WP9, ASTM A403 GR WP347H-S, and ASTM A403 GR WP347-S, ensuring optimal performance under a variety of operating conditions.

ASME B16.9 ASTM A403 GR WP347-S 45 drgree elbow
Product Overview
The order involved the production of 45° and 90° elbows in both long radius and short radius configurations. These elbows are designed to efficiently change the direction of fluid flow in pipelines while minimizing pressure drop and turbulence. The different radii and sizes ensure flexibility in application, catering to both standard and compact piping systems.
45° Long Radius Elbows: Used for moderate directional changes, these elbows are designed to offer smooth flow transitions.
90° Long Radius Elbows: Ideal for sharper directional changes in larger systems, offering minimal resistance and ensuring efficient fluid movement.
90° Short Radius Elbows: These elbows allow for tighter turns, ideal for space-constrained installations.
Material Selection
The materials chosen for this order were specifically selected to meet the requirements of high-pressure and high-temperature applications. Each material provides unique benefits:
ASTM A234 WP5:
A low alloy steel commonly used for high-temperature applications.
Offers excellent strength and resistance to corrosion at elevated temperatures, making it suitable for power generation and petrochemical industries.
ASTM A234 WP9:
Another low alloy steel material, WP9 is known for its enhanced creep strength and resistance to oxidation.
It is typically used in systems that operate at higher temperatures and pressures, such as in the power and refining industries.

ASME B16.9 ASTM A403 GR WP347-S 90 degree elbow
ASTM A403 GR WP347H-S:
This material is stainless steel, stabilized with niobium, offering excellent resistance to intergranular corrosion and oxidation at high temperatures.
Ideal for chemical processing, petrochemicals, and power generation systems requiring high temperature and corrosion resistance.
ASTM A403 GR WP347-S:
Similar to WP347H, this stainless steel material provides outstanding performance in high-temperature applications.
The primary difference is its slightly lower niobium content, which still provides excellent resistance to high-temperature oxidation and intergranular corrosion.
Quality Assurance at Haihao Group
At Haihao Group, we prioritize quality control throughout the production process to ensure that every product meets the required standards. For this order, rigorous checks were conducted, including:
Dimensional Inspection: Ensuring the elbows met the exact specifications for diameter, thickness, and radius.
Material Testing: Verifying that each batch of material adhered to the required chemical composition and mechanical properties.
Pressure Testing: Ensuring that the elbows are capable of handling high-pressure environments without failure.
