Operating Characteristics and Equipment Risk Points
The high-pressure manifold works under extremely harsh conditions and has several notable characteristics:
1. Alternating Pressure Fatigue Loads: The drilling pump is a reciprocating pump; its output pressure is not constant. Continuous periodic pulsations impact the manifold, subjecting the line to long-term alternating stress, and long-term operation can easily cause fatigue cracks in welds and connections.
2. Solid Particle Erosion and Wear: The drilling fluid contains hard cuttings and barite particles that scour the inner wall of the line at high speed. At elbows and tees, where the flow direction changes, scouring is most severe; prolonged use can thin the pipe wall and cause washouts.
3. Severe Vibration and Impact: Pressure pulsation can trigger violent pipeline vibration. If the fixing and damping measures fail, the unions and flange connections may loosen, causing mud washouts.
4. High Safety Risk: The fluid inside the line is under high pressure of tens of MPa. Once a fitting cracks or a connection is blown open, high-pressure mud spraying can easily cause personal injury, making the manifold a key high-hazard equipment item under focused management on drilling sites.
Common faults: union (hammer union) washouts, erosion-induced wall thinning of elbow inner walls, weld cracking, internal leakage of valves, damaged connection seals, and loosened support brackets.
