Product Introduction: Plug Board Plug board is a multi-port integrated block accessory widely matched with mud pump discharge manifolds, hydraulic manifolds and pipeline control systems, also named manifold plug plate. It serves as the centralized mounting base for pressure gauges, shear relief valves, blowdown plugs, stop plugs and small branch pipelines. Material & Structure Forged from high-strength alloy steel with thick wall structure to bear full system working pressure. The interior is provided with interconnected flow passages, and multiple standard threaded/through-hole interfaces are reserved on the surface. Each port is equipped with matching sealing rings and threaded plugs to achieve sealed blocking when no components are installed. The bottom surface is precision milled flat, which can be closely fitted with the discharge manifold body and locked by flange bolts, forming an integrated pressure-bearing structure without leakage gaps. ## Main Functions 1. Centralized interface integration Concentrate pressure measurement, overpressure protection, blowdown and branch outlet interfaces on one board, simplify pipeline layout, avoid messy scattered branch pipes, and reduce vibration-induced joint leakage. 2. Flexible port switching Unused interfaces can be sealed with solid plugs; users can install pressure gauges, gate valves or relief valves according to construction demands, with strong scene adaptability. 3. Convenient maintenance and pressure relief The reserved blowdown plug can quickly release residual pressure in the manifold before equipment overhaul, discharge sediment and residual mud inside the pipeline, improving maintenance safety. 4. Buffer flow impact Integrated flow channel transition design reduces local turbulence of high-speed sand-containing mud, lowering partial scouring wear of the manifold assembly. Core Advantages 1. High pressure resistance and anti-fatigue: Integral forging eliminates welding weak points, suitable for long-term alternating high-pressure impact of drilling fluid. 2. Strong interchangeability: Standard mounting hole spacing and thread specifications match mainstream mud pump discharge manifolds, easy to replace on site. 3. Good sealing performance: Each interface is equipped with independent sealing ring grooves, effectively preventing high-pressure mud leakage. 4. Compact structure: Saves installation space of the fluid end, reduces overall pipeline vibration amplitude. Application Scenarios Mainly mounted on the upper part of triplex mud pump discharge manifold, matched with pressure gauges, shear relief valves and blowdown plugs. It is an essential auxiliary integrated component of the mud circulation high-pressure pipeline system, realizing unified monitoring and safety control of pump discharge pressure.
