Flanges

Flanges are integral components for joining pipes, containers, or machinery parts, providing essential flexibility and strength to mechanical systems. Commonly paired and secured through welding, threading, or bolting, flanges serve critical roles, such as increasing joint stability, attaching parts securely, and enabling straightforward maintenance and disassembly. With options like threaded flanges, which eliminate the need for welding, to robust weld neck flanges suited for high-pressure systems, our range addresses diverse technical requirements, enhancing the operational efficiency and safety of piping systems.

Our Threaded Flanges are designed for high-pressure applications, where a screw-in installation ensures ease of use without welding. Socket Weld Flanges are favored for smaller pipes in low-temperature and pressure applications, providing a single fillet weld connection for secure and simple installation. Slip-On Flanges, which slide over pipes, require welding on both sides for strength, making them ideal for systems with high flow rates. Lap Joint Flanges facilitate frequent disassembly and maintenance, particularly beneficial in compact spaces, while Weld Neck Flanges are chosen for high-stress, high-temperature systems due to their superior structural integrity.

Blind flanges, used for sealing pipe ends, offer unmatched sealing capabilities with proper gaskets, ensuring reliable termination and maintenance access when needed. Specialty Flanges, such as orifice, nipo, and reducing flanges, are available for applications with unique requirements, providing tailored solutions for specific industrial environments. Each flange type from Solitaire Steel is crafted to ASME, ASTM, or DIN standards, offering dependable performance across varying pressure ratings (e.g., 150#, 300#, 600#) and temperature tolerances, meeting the demands of industries such as oil and gas, power generation, and construction.

Our product standards and markings ensure straightforward identification, with labels for material grade, pressure rating, and size, aiding in seamless part replacement and verification. Solitaire Steel’s extensive selection of flanges is engineered to optimize system efficiency, with precise dimensions that accommodate industry-standard gaskets and bolts, ensuring a secure, leak-proof connection. For assistance with selecting the right flange type, our technical team provides expert guidance to support your specific application needs.
