Hexagon Socket Screw Plug

In applications such as pipeline termination, pressure testing, or equipment maintenance, there is a critical need for a sealing component that is structurally robust, reliably sealed, and easy to install. Compared to traditional pipe caps or welded blinds, the Flanged Plug (T-type Plug) offers a more efficient and cost-effective solution. Designed specifically to match standard flange dimensions, it can be bolted directly to the end of a pipe or equipment flange, enabling rapid installation and removal.

The core advantage lies in its unique "T-shape" structural design. This design not only enhances structural rigidity under high pressure and reduces the direct impact of internal fluid turbulence on the sealing surface but also optimizes stress distribution. This ensures superior long-term sealing performance even under frequent disassembly or system pressure fluctuations. The Flanged Plug is ideal for working conditions requiring repeated opening/closing or as a permanent backup seal, significantly saving time and labor costs during maintenance.

Product Features

T-Shaped Reinforced Design: The reinforced center-raised design significantly enhances overall rigidity, effectively resisting system pressure and potential water hammer impacts while preventing deformation for long-term sealing.
Full-Face Sealing Surface: The precision-machined sealing surface works perfectly with standard flange gaskets to achieve uniform compression and eliminate potential leak points.
Standard Flange Profile: Fully compliant with major flange standards (such as ANSI, DIN, JIS, etc.) regarding outer dimensions and bolt hole patterns, ensuring universal compatibility and interchangeability.

Applications

Pipeline Termination: Permanent or temporary sealing for process piping and transmission lines.
Pressure Test Interfaces: Serves as a reliable isolation point during hydrostatic or pneumatic testing, easily removed after completion.
Maintenance Isolation: Used to isolate specific pipe sections during the repair of pumps, valves, heat exchangers, and other equipment.
Future Port Provision: Securely seals pre-installed ports intended for future system expansion.
