    Product Production Process

    • 1 Core process: Relying on advanced CNC machine tools and CNC machining centers, following the five major links of raw material selection, precision machining, sealing surface grinding, assembly and debugging, and full process quality inspection.
    • 2 Raw material processing: Strictly screen the raw materials before entering the site to ensure that the material performance meets the standards.
    • 3 Key processing: The sealing end face adopts professional grinding technology to improve flatness and smoothness; The corrugated pipe adopts processes such as stamping, cleaning, welding, and heat treatment, while the PTFE corrugated pipe adopts a single blade turning process.
    • 4 Assembly requirements: The parts should be cleaned and pre treated with alcohol or specialized cleaning agents, and operated according to the static ring installation, dynamic ring and shaft sleeve assembly, and overall assembly process to ensure that the springs are concentric and the sealing surface is evenly stressed.
    • 5 Quality inspection standards: The finished product undergoes multiple performance tests such as high temperature resistance, sealing, and corrosion resistance. Dimensional testing is carried out using tools such as coordinate measuring instruments and micrometers. Surface quality is verified through optical microscopy, and the entire process is traceable.

    Features

    • 1 Structural design: Interior, internal flow, single end face, single spring, unbalanced structure, overall exquisite and reasonable, highly adaptable.
    • 2 Specification range: The specification covers 10–110mm and can meet the sealing requirements of different equipment.
    • 3 Material selection: The sealing end face is made of high-quality materials such as graphite, silicon carbide, and hard alloy, and the auxiliary sealing is made of elastic materials such as nitrile, ethylene propylene, and fluorine rubber. Metal components are made of corrosion-resistant materials such as 304, 316L stainless steel, and Hastelloy C.
    • 4 Performance parameters: Can withstand temperature range of -20℃ to 300℃, working pressure ≤ 1.2MPa, linear velocity ≤ 10m/s, axial displacement ± 0.5mm.
    • 5 Compatible media: Suitable for water, oil, and general corrosive solutions. Some special materials are resistant to strong acid, alkali, and chlorine corrosion.
