ASME Steel Hub Type Casting Services Flange Product

In demanding industrial piping systems, the integrity of every connection is paramount. Our ASME Steel Hub Type Casting Services specialize in producing high-performance, hub-type flanges that meet rigorous American Society of Mechanical Engineers (ASME) standards. These flanges are engineered for superior sealing capability and structural strength in high-pressure and high-temperature applications, providing a reliable solution for critical infrastructure.

Premium Material for Robust Performance

We utilize certified carbon steel (e.g., A216 WCB) and alloy steel (e.g., A217 WC6/WC9) grades specifically suited for pressure-containing components. These materials offer excellent tensile strength, yield strength, and impact resistance at both ambient and elevated temperatures. The steel's inherent durability ensures long-term performance, resisting deformation under bolt load and system pressure, which is crucial for maintaining a leak-free seal over the flange's operational lifespan.

Precision-Controlled Production and Machining

Our manufacturing process begins with advanced sand casting or investment casting techniques to create a near-net-shape hub flange with a dense, homogeneous grain structure. The "hub" or "raised face" design is integrally cast, providing enhanced structural support behind the sealing face. Each casting is then subjected to precise CNC machining on all critical surfaces. This includes machining the raised face to the required surface finish (e.g., serrated), boring the inner diameter, and drilling the bolt holes to exact ASME B16.5 specifications. This ensures perfect alignment with mating flanges and safe, reliable operation.

Critical Applications Across Industries

ASME-compliant hub type flanges are essential components in a wide range of severe-service industries. They are the connection of choice in oil and gas pipelines, petrochemical and refinery process lines, power generation plants, and high-pressure water systems. The hub design provides a strong, rigid connection that minimizes the risk of leakage, making it ideal for handling volatile, toxic, or expensive media where safety and environmental protection are top priorities.
