Supply of high-quality flange products for Russian customer
The Russian customer placed an order for a comprehensive batch of flange products designed to meet the complex needs of industrial pipeline systems. This batch included weld neck flanges, spectacle blind flanges, ring spacers, and spades, all manufactured to exacting standards to ensure compatibility, reliability, and performance under extreme conditions.
ASME B16.5 RTJ Weld Neck Flange
The weld neck flanges (WN), a key component of the order, were manufactured in accordance with the ASME B16.5 standard. This industry-recognized standard governs the design, dimensions, and material requirements for flanges that are commonly used in high-pressure and high-temperature applications. Weld neck flanges are designed for strong, long-lasting connections and are crucial in applications where the integrity of the pipeline must be maintained under severe operational conditions.
Blind flange with handle spader
In addition to the weld neck flanges, the order also included spectacle blind flanges, ring spacers, and spades. These products were manufactured in accordance with the ASME B16.48 standard, which specifies the design, material, and dimensions of flanges used for pipeline isolation. Spectacle blind flanges, ring spacers, and spades are typically used to isolate a section of pipeline for maintenance or to prevent flow through a particular pipeline section, making them critical for safety and operational flexibility.
Spectacle Blind Flange
The specific choice of materials—A350 GR.LF2CL.1, A182 GR.F304, and A516 GR.70—demonstrates the Russian customer’s emphasis on durability and performance. The selection of A350 GR.LF2CL.1 material for both the weld neck flanges and the spectacle blind flanges, ring spacers, and spades highlights the importance of low-temperature resistance, which is particularly relevant in environments where the pipelines might be exposed to cold climates or cryogenic fluids. Additionally, the incorporation of A182 GR.F304 stainless steel in the weld neck flanges ensures resistance to corrosion, which is essential for maintaining the integrity of pipelines, especially those used for transporting aggressive fluids or gases.
ASME B16.48 Ring Spacer Flanges
Quality assurance plays a central role in this order. Each batch of products is subjected to a series of strict inspections and testing procedures, including dimensional checks, material verification, and non-destructive testing (NDT). This ensures that the products meet not only the technical requirements but also the high safety and reliability standards demanded by industries such as oil and gas, petrochemical, and marine engineering. Furthermore, certification of the materials and products is typically provided, ensuring transparency and traceability, which is vital for both the supplier and the end user.
The recent order from the Russian customer for weld neck flanges, spectacle blind flanges, ring spacers, and spades showcases the high standards of quality and reliability required in the global pipeline industry. With materials such as A350 GR.LF2CL.1, A182 GR.F304, and A516 GR.70, and adherence to ASME B16.5 and ASME B16.48 standards, Haihao Group is able to provide products that ensure safety, durability, and performance in challenging environments.
