DS Short Welding Liner
KINGMAN DS sanitary union Welding Liner is precisely processed from SS304/SS316L stainless steel in full compliance with DS sanitary standards. As the core sealing and flow-guiding component of DS unions, it features high-precision flat sealing face, regular through flow path and natural transition. Full-range mirror polishing ensures unobstructed fluid flow. It focuses on pipeline leveling, pressure bearing and smooth flow guidance, completing standardized sealing assembly with round nuts and cloud heads. With high structural rigidity and dimensional accuracy, it resists deformation after repeated compression and disassembly, suitable for long-term sterile transportation and online cleaning of DS-standard food and pharmaceutical hygienic pipelines.

Features
- 1. Manufactured strictly in accordance with DS pipeline standards with accurate flatness and bore size, ensuring high coaxiality and perfect matching with DS union accessories of the same specification.
- 2. High-purity mirror-polished flow path delivers smooth inner surface without uneven blind areas, reducing adhesion and residue of viscous and crystallizable media for thorough cleaning.
- 3. Uniformly stressed flat sealing face provides complete fitting area, effectively resisting positive and negative pressure impact to eliminate micro-leakage and penetration pollution.
- 4. Precise compact structure with excellent fatigue resistance maintains facial flatness accuracy after long-term repeated locking and disassembly cycles.
- 5. Excellent resistance to acid, alkali, temperature and cleaning solvent flushing adapts to high-frequency CIP cleaning and SIP sterilization, sustaining high pipeline hygiene standards.
- 6. Standardized universal structure with precise positioning accelerates DS union assembly and improves overall pipeline docking accuracy on site.
Working Principle
The DS union Welding Liner operates based on precise leveling, uniform pressure bearing and clean flow guidance. During assembly, the flat face fits closely with the gasket and evenly disperses the axial locking force of the round nut across the entire sealing area, forming a tight, balanced and offset-free sealing structure to avoid biased-pressure leakage fundamentally. Media flows through the straight smooth flow path with gentle transition, free of turbulence and dead retention to ensure stable and sterile high-purity fluid delivery. Its high-rigidity structure buffers pipeline vibration and pressure impact to protect the sealing interface. Repeated disassembly, cleaning and reassembly fully meet the sterile, maintainable and zero-residue process requirements of DS-standard hygienic pipelines.
