Product Introduction: Discharge Manifold Discharge manifold is a high-pressure integrated pipeline assembly matched with triplex mud pump fluid end, widely used in oil drilling, geological exploration and horizontal directional trenchless construction. It serves as the main flow channel for high-pressure drilling fluid discharged from pump cylinders, gathering slurry from multiple cylinder bores and delivering it to downstream pipelines, gate valves and wellhead equipment. Structure & Material The manifold main body is integrally forged from thick high-strength alloy steel with full penetration welding for branch joints, featuring ultra-high pressure bearing capacity and strong anti-fatigue performance against alternating slurry impact. It is equipped with multiple interfaces for cylinder cover connection, shear relief valve mounting, pressure gauge installation and branch pipeline output. Internal flow channels adopt smooth curved transition design without sharp corners, effectively reducing mud flow resistance and avoiding cuttings accumulation and local abrasion. Each connecting end is fitted with standard forged flanges and matched sealing rings to eliminate high-pressure slurry leakage risks. Core Supporting Components 1. Shear relief valve interface: Install safety overpressure protection device to release pressure when pipeline blockage occurs; 2. Pressure gauge mounting port: Real-time monitor the discharge pressure of the mud pump circulation system; 3. Gate valve branch outlets: Realize independent switching control of different construction pipeline branches; 4. Blowdown plug: Convenient for regular cleaning of sediment and residual mud inside the manifold after construction shutdown. Key Performance Advantages 1. High structural rigidity: Integrated thick-wall forging structure resists long-term high-frequency hydraulic shock, no deformation or cracking under rated working pressure; 2. Low wear and long service life: Inner wall wear-resistant treatment reduces scouring damage from sand-containing drilling fluid; 3. Modular standard design: Compatible with mainstream models of triplex mud pumps, all connecting dimensions are unified for convenient replacement and on-site assembly; 4. Easy maintenance: Detachable plug and flange structure allows quick internal cleaning and sealing ring replacement without overall disassembly of the manifold. Application & Functional Value Installed on the outlet side of mud pump cylinder covers, it concentrates the high-pressure mud output of three cylinders into a unified conveying pipeline, realizes centralized pressure monitoring and overpressure safety protection. It can quickly cut off fluid flow through matched gate valves to facilitate fluid end maintenance such as liner and valve replacement. As the core high-pressure gathering pipeline of the mud circulation system, it ensures stable, uniform output of drilling fluid pressure and flow, prevents pipeline blowout and slurry leakage safety hazards, and is an indispensable key pressure-bearing assembly for drilling construction.
