Product Introduction: Flange Flange is a general high-pressure connecting component for mud pump fluid end, manifolds and slurry pipelines, widely applied in oil drilling, geological exploration and horizontal directional trenchless construction. It connects pump bodies, dampeners, pipelines and safety valves to form a sealed mud circulation channel. Made of thick alloy steel or carbon steel via forging and precision machining, the flange features high pressure-bearing capacity and structural rigidity. Evenly distributed bolt holes ensure uniform clamping force after assembly; the smooth sealing surface cooperates with rubber gaskets to effectively prevent high-pressure sand-containing mud leakage under alternating hydraulic impact. Multiple types available: welded flange, threaded flange, blind flange, etc., adapting to different pipeline connection modes. Standard thread, bore and bolt specifications deliver strong interchangeability with most mainstream mud pump supporting parts. The whole surface is shot-blasted and coated with anti-rust paint, resisting erosion from acidic/alkaline drilling fluid, rainwater and mud on open-air construction sites. The inner flow channel is smooth without dead angles to avoid cuttings deposition and pipeline blockage. Split assembly design enables quick disassembly for pipeline overhaul, filter mesh cleaning and component replacement, greatly reducing equipment downtime. It fixes each section of the high-pressure pipeline to reduce vibration displacement and joint loosening risks, avoiding safety hazards such as slurry blowout. As a universal connecting fitting for mud circulation systems, it ensures tight, stable and safe transmission of drilling mud, lowers pipeline maintenance frequency and supports continuous high-efficiency construction operation.
