Stainless steel constant pressure reducing five-way welded flange pipe fitting

Stainless steel constant pressure reducing five-way welded flange pipe fitting

The design of stainless steel sanitary welding tees is not only for simple fluid diversion or confluence, but also to meet the process needs of high cleanliness, pollution-free and efficient transportation. It eliminates the possible leakage hazards and cleaning blind spots caused by traditional connection methods through welding connections, ensuring that the hygiene standards of the entire pipeline system meet strict industry requirements. Its interior has been polished to keep the fluid flowing smoothly on the inner wall of the pipeline, avoiding deposition and microbial growth, and is especially suitable for biopharmaceuticals, electronic chemicals and high-end food manufacturing. In addition, it can optimize fluid dynamics, reduce pressure losses, improve delivery efficiency, and support CIP/SIP cleaning and sterilization to ensure the sustained stability of the production environment.

Working Principles

These fittings operate by integrating multi-port conduction, diameter adaptation, and sealed pressure retention. Fluid enters via one main port and distributes or converges through the five customized-diameter ports, matching different pipeline sizes to ensure steady flow without excessive resistance. The welded flange connections, secured by bolts, form airtight seals that prevent leakage under constant pressure. Crafted from corrosion-resistant stainless steel, the fittings maintain structural integrity, stabilizing pressure across the system while facilitating efficient multi-directional fluid transfer in industrial pipelines.

Features

● The stainless steel sanitary welded tee uses computational fluid mechanics (CFD) simulation to optimize the internal runner, so that the flow distribution of the three interfaces is uneven but the pressure loss is minimized, and turbulence and blind spots are avoided.

● After the welding is completed, the stainless steel sanitary welding tee is used to coat ultra-fine stainless steel powder on the surface of the weld to form a nanocrystalline structure layer to improve the weld's resistance to intergranular corrosion.

● After welding of stainless steel sanitary welding, the tee is subjected to high-frequency mechanical vibration treatment to redistribute the residual stress and reduce it by more than 30%, avoiding fatigue cracks under long-term pulse pressure.

● Stainless steel sanitary welding tee is superimposed on traditional electrolytic polishing to reduce the inner surface roughness to Ra≤0.1μm, and the thickness uniformity of the passivation film is increased by 50%.

● When welding sanitary welding of stainless steel, infrared thermal imager is used to monitor the temperature of the heat-affected zone in real time, and dynamically adjust the argon protection flow through the PID algorithm.

● Stainless steel sanitary welding tee pre-installs a nickel-based alloy transition layer between the 316L matrix and the weld, forming a gradient metallurgical combination through diffusion welding to solve the problem of galvanic corrosion during different types of pipe connections.
