Core Manufacturing Process for Metal Double-Socket Connectors
Raw Material Selection:High-strength materials such as A105 carbon steel, 304 stainless steel, and 15CrMo alloy steel are commonly used to suit high-pressure operating conditions in sectors like petroleum, nuclear power, and metallurgy.
Die-Forged Blank Formation: Round steel bars or ingots are formed into basic blanks via die forging; an 8° external draft angle and a 12° internal draft angle are incorporated at the parting line to ensure demolding precision.
Precision Machining: Lathes are used for secondary processing of the blanks to precisely machine the socket openings at both ends, ensuring interface dimensional tolerances meet standards such as ANSI/ASME B16.11 and GB/T 14383-2008.
Beveling and Sealing Treatment:Welding areas are beveled according to standards; some products feature an L-shaped reinforcement ring to enhance the interface's compressive strength, and protective covers are applied over exposed sealing areas to improve corrosion resistance.
Final Inspection: Individual pressure testing and dimensional verification are conducted to ensure the product's pressure rating meets design requirements (e.g., 3000LB, 6000LB, or 9000LB).
Manufacturing Process for Low-Pressure PPR Double-Socket Connectors
Raw Material Pre-treatment:Polypropylene pellets are used as the raw material, undergoing drying and mixing processes.
Integrated Injection Molding: Direct injection molding using specialized molds forms the socket structures at both ends in a single step, ensuring interface concentricity.
Heat-Fusion Compatibility: Designed with flexible dual-fusion socket connection technology, the product allows for thermoplastic sealing via heat fusion during installation, making it suitable for low-pressure civil water supply applications.
