11643001 Blocking plate Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 11643001 sealing plate boasts four major advantages: tight sealing, high strength, corrosion resistance, and easy installation. It is widely used in heavy equipment and piping systems such as cranes, excavators, and chemical pipelines, playing a crucial role in sealing pipe openings and equipment interfaces, and isolating media. It effectively blocks fluid leakage, prevents safety hazards caused by improper valve closure, ensures stable operation of equipment and piping systems, is compatible with various machine models and pipe specifications, and is easy to install and ready for immediate use, meeting the core needs of industrial pipeline isolation and sealing.
This product is made of high-quality materials and precision-machined, strictly adhering to industrial sealing and isolation accessory quality standards. The main body is made of Q235B carbon steel (304 stainless steel and 316L materials can be customized), forged, CNC machined, and surface-treated for corrosion protection. Its structure is flat and dense, free of defects such as sand holes and air bubbles, possessing excellent pressure resistance, corrosion resistance, and wear resistance. It effectively solves problems such as sealing failure, rust, and deformation of plug plates, reducing equipment maintenance costs and extending the service life of pipeline systems. Its optimized planar sealing structure fits pipe flange interfaces, adapting to PN10-PN16 pressure ratings. It can be combined with sealing components to achieve zero-leakage sealing, suitable for complex industrial conditions such as high dust, high oil, and high pressure. Balancing sealing reliability with ease of assembly, it can precisely match the sealing and isolation needs of various pipelines and equipment.
