Component Specifications

Definition
The Plug Body/Gate Plate is a critical flow control component in industrial tapping systems, consisting of a precisely machined body that houses a gate mechanism. It functions as the primary interface between the main pipeline and the tapping connection, featuring engineered sealing surfaces, alignment guides, and mounting provisions. This component ensures controlled fluid diversion during maintenance, repair, or system modification operations while maintaining system integrity and preventing leaks.
Working Principle
Operates through linear or rotational movement of the gate plate within the plug body. When closed, the gate plate creates a complete seal against the flow path using precision-machined surfaces and sealing elements. During operation, the gate plate retracts or rotates to create an opening, allowing controlled fluid flow through the tapping connection. The mechanism typically employs mechanical actuators, hydraulic systems, or manual controls to achieve precise positioning.
Materials
Carbon steel (ASTM A216 WCB), Stainless steel (316/304), Duplex stainless steel (2205), Alloy steel (A182 F11/F22), with optional coatings: PTFE, nickel plating, or ceramic coatings for corrosion resistance.
