PFA PTFE Lined Tri-Clamp Elbow
KINGMAN sanitary lined tri-clamp elbow is a hygienic pipeline fitting used to change fluid flow direction in corrosive piping systems. It uses 304 or 316L stainless steel as the outer shell. Customers may choose PTFE lining or PFA lining for all wetted inner surfaces. Both ends adopt tri-clamp quick connection for fast assembly and disassembly. PTFE lining delivers outstanding general corrosion resistance with cost advantages. PFA lining offers higher surface smoothness and better high-temperature performance. Both materials comply with hygienic standards and support CIP/SIP cleaning & sterilization. Widely applied in pharmaceutical, food, fine chemical, new energy and environmental protection industries for pipeline turning and corrosive fluid transportation.

Features
- Tri-clamp quick connection on both ends. No on-site welding required, simple and rapid assembly and disassembly. Strong interchangeability, perfectly compatible with standard sanitary tri-clamp fittings for convenient pipeline layout and maintenance.
- Optional lining: PTFE or PFA for all wetted surfaces. PTFE can resist strong acid, strong alkali, oxidizing agents and most corrosive chemical fluids with good cost performance. PFA has ultra-smooth surface, excellent high-temperature resistance and non-stick property, suitable for high-temperature, high-purity and strict cleaning working conditions. Both linings protect the stainless steel outer shell from chemical corrosion.
- Smooth inner lining wall with low friction coefficient. It effectively reduces medium adhesion and residue, avoids material accumulation, fully meets CIP/SIP in-place cleaning and sterilization requirements for hygienic and high-purity process working conditions.
- Stainless steel outer body with CNC precision machining. It has stable mechanical strength and reliable pressure bearing capacity. The stainless steel shell provides solid structural support and prevents external atmospheric corrosion to extend service life.
- Optimized curved transition design. The bending part adopts streamlined smooth transition, which reduces fluid turbulence and pressure loss, ensures stable medium flow when changing direction.
- Integrated lining molding process. The PTFE or PFA liner is tightly bonded with stainless steel substrate. Under corresponding rated working temperature and pressure, it can effectively prevent lining peeling, bubbling and falling off.
Working Principle
This sanitary lined tri-clamp elbow acts as a pipeline direction-changing component. When fluid medium flows into the inlet of the sanitary lined tri-clamp elbow, the streamlined inner lining (PTFE or PFA selected as required) guides the fluid to smoothly change flow angle inside the elbow. The fluoroplastic lining separates corrosive medium from the stainless steel outer shell to prevent shell corrosion. The medium flows out from the other port after completing direction turning, without changing the property of the fluid, realizing the function of pipeline flow direction conversion.
