Product Introduction: Welded Flange Welded flange is a standard pressure-bearing connecting part for mud pump fluid pipelines, manifold assemblies and dampener joints, widely applied in oilfield drilling, geological exploration and trenchless horizontal directional engineering. It serves as a stable connection interface to link pump bodies, high-pressure pipelines and auxiliary equipment, realizing sealed fluid transmission of sand-containing drilling mud. Fabricated from thick high-strength carbon steel/alloy steel plates via cutting, forming and full penetration welding, this flange features high structural rigidity and pressure resistance. The integrated welding structure eliminates assembly gaps, effectively resisting long-term alternating hydraulic impact without deformation or cracking under rated working pressure. Precision-machined sealing face with uniform bolt hole distribution ensures even fastening force after assembly. It matches rubber sealing gaskets perfectly to prevent high-pressure mud leakage at joints. Standard bore sizes and bolt specifications offer universal interchangeability, compatible with most mud pump pipeline matching systems. The whole body undergoes rust removal, shot blasting and anti-corrosion coating treatment, resisting erosion of acidic, alkaline drilling fluids, mud and rainwater in outdoor construction sites. Butt-welded end design enables seamless welding with steel pipes, guaranteeing smooth internal flow channels to avoid mud sediment and blockage. Simple installation and disassembly structure facilitates on-site pipeline layout, overhaul and component replacement. It firmly connects each section of the slurry circulation pipeline, reduces vibration displacement and joint leakage risks, stabilizes system flow and pressure, and avoids safety hazards such as pipeline blowout. As a core pipeline connecting fitting for mud pump supporting systems, it ensures tight, safe and continuous delivery of drilling fluid, lowering pipeline maintenance frequency and improving overall construction efficiency.
