Carbon Steel Slip On Flanges are specially designed ring shaped pipe components that slide directly over the outer diameter of a pipe before being welded into place using two separate fillet welds, one on the inside bore and one on the outer hub. These versatile components feature a low profile hub, precise interior bore dimensions, exceptional structural integrity, and superior resistance to mechanical stress, making them a preferred choice for alignment accuracy in fluid and gas transmission systems. Manufactured in compliance with international standards such as ASME B16.5, ASME B16.47, and EN 1092 1, these components are available across pressure ratings including Class 150, Class 300, Class 600, Class 900, Class 1500, and Class 2500 in nominal sizes ranging from 1/2 inch to 60 inches. The slip on configuration eliminates the need for extremely precise pipe cutting, which drastically simplifies installation while reducing overall labor overheads. Solitaire Overseas is a premier manufacturer, stockist, and global exporter of high quality Carbon Steel Slip On Flanges engineered to meet strict industrial tolerances for global projects.

Carbon Steel Slip On Flanges are pipe flanges that slide over the outside diameter of a pipe and are welded in place. They are commonly used to connect pipes, valves, pumps, and other equipment in industrial piping systems.
Carbon Steel Slip On Flanges are manufactured according to standards such as ASME B16.5, ASME B16.47, BS 3293, DIN 2576, EN 1092-1, and ISO 7005-1, depending on the required size, pressure class, and application.
Common materials include ASTM A105, ASTM A350 LF2 Class 1 and Class 2, ASTM A694 F42, F46, F52, F60, F65, and F70, as well as ASTM A516 Grade 70, subject to the required specification and application.
Carbon Steel Slip On Flanges are available with Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ) facings. The appropriate facing type depends on the piping system, gasket arrangement, pressure rating, and service conditions.
A Slip On Flange fits over the outside of the pipe and is secured with fillet welds, while a Weld Neck Flange has a tapered hub and is butt-welded to the pipe. Slip On Flanges are generally easier to install and are commonly selected for lower-stress and general piping applications.
Carbon Steel Slip On Flanges are used in oil and gas, petrochemical, refinery, power generation, and chemical processing applications. They are commonly used for connecting pipes, valves, pumps, equipment, and other piping components.
Carbon Steel Slip On Flanges are available in higher pressure classes, but their suitability depends on the pipe size, temperature, pressure, material grade, and applicable design standard. For demanding high-pressure or high-temperature services, Weld Neck Flanges may be preferred.
