Silp on Flange

These are Stainless Steel Weld Neck Pipe Flanges (Bulk Packaging)—heavy-duty piping fittings for industrial pipeline connections. Each flange features a tapered neck (designed for butt-welding to pipe ends, which boosts structural stability and pressure-bearing capacity) and a flange face with evenly spaced bolt holes, enabling tight, leak-proof joints when paired with gaskets and fasteners.

These are Brass Slip-On Pipe Flanges (Multiple Sizes)—piping fittings designed for connecting pipeline sections in fluid systems. Each flange has a central bore (intended to slide over pipe ends for welding fixation) and evenly spaced bolt holes, enabling tight, leak-resistant joints when paired with gaskets and fasteners.

This component is a Galvanized Carbon Steel Slip-On Pipe Flange—a common piping fitting for joining pipeline sections. It has a hollow central bore (designed to slide over pipe ends for welding fixation) and four evenly spaced bolt holes around its flat flange face, which allows it to form tight, leak-proof connections with matching flanges (when used with gaskets and fasteners).

These are Brass Slip-On Pipe Flanges—a critical piping fitting used to connect pipes, valves, or equipment in fluid systems. They feature a hollow central bore (designed to slide over pipe ends for welding/securing) and evenly spaced bolt holes around the flange face, which allows tight, leak-proof assembly when paired with gaskets and fasteners.

A Flat Face (FF) Flange is a type of piping flange with a flat sealing surface, designed to mate with another flat-faced flange (or a flange with a matching surface). It’s commonly used in low-pressure, non-critical applications (e.g., water, air systems) to connect pipes, valves, or equipment. Standards (like BS 4504/EN 1092, ASME B16.5) define its dimensions (bolt holes, diameter, thickness) and pressure ratings (e.g., PN16, Class 150).

This image displays a large, heavy-duty stainless steel flat flange, situated in a workshop environment. It features a polished metallic surface with numerous evenly spaced mounting holes around its edge, and a wooden board is placed inside the flange (likely for protection). In the background, wrapped batches of similar components are visible. As a large-diameter pipeline fitting, this flange is designed for heavy industrial pipe connections (e.g., in petrochemical or energy systems), providing a secure se

This image shows a black plastic flat flange, which has evenly spaced mounting holes around its edge and multiple circular sealing grooves on the inner surface. It is placed on a textured light-colored backing material. As a corrosion-resistant pipeline fitting, this component is mainly used for low-pressure pipe connections (such as water supply systems), and the internal sealing grooves are designed to improve the tightness of the pipe joint.

This image displays a brass flat flange held by a hand, with technical specifications (S400, PN16, 8", 2531) engraved on its side. The flange has a polished golden-brass surface and a flat, hole-equipped structure. It is a standardized low-pressure pipeline fitting (rated for 1.6MPa), designed for 8-inch diameter pipe connections in systems like water supply or HVAC. The engravings denote its size, pressure rating, and batch details.
