Key Features & Construction
1. Material:
Crafted from superior austenitic stainless steel, our meticulously selected range includes prevalent grades such as:
304 (1.4301 / UNS S30400): A highly versatile, general-purpose grade celebrated for its superb corrosion resistance, impressive formability, and excellent weldability. Ideal for applications involving water, steam, food processing, and mild chemical environments.
316/316L (1.4401/1.4404 / UNS S31600/S31603): Enhanced by the addition of molybdenum, this grade delivers exceptional resistance to chloride-induced corrosion, including pitting and crevice corrosion. Perfect for chemical processing, marine, pharmaceutical, and highly corrosive settings. 316L further offers enhanced weldability and superior resistance to intergranular corrosion.
Material Properties: Renowned for its extraordinary resistance to corrosion and oxidation, this material exhibits high strength across a broad temperature range, coupled with exceptional ductility and toughness, ensuring unwavering reliability.
2. Design:
Tee Body: Engineered with precision, this component presents one run inlet, one run outlet, and a perpendicular or angular branch outlet. Available in either equal or reducing configurations, the standard branch angle is set at a precise 90°.
Welding Ends: Typically found at the run ends, these are meticulously crafted with beveled ends, like a V-groove, for butt welding (BW) to the pipeline. This design assures optimal strength and leak-proof integrity, even under the most challenging high-pressure, high-temperature, or high-vibration conditions.
Flanged End: Usually located at the branch outlet, and occasionally at the run ends, it is equipped with a high-quality standard stainless steel flange, facilitating secure and efficient connections.
Flange Types: A diverse range of options are available including:
Slip-On Flange (SO): Perfect for low to medium pressure applications, this type is designed for straightforward and efficient installation.
Weld Neck Flange (WN): Specifically crafted for high-pressure and temperature or cyclic loading conditions, the tapered hub optimizes stress distribution, making it the most reliable choice for challenging environments.
Socket Weld Flange (SW): Ideal for smaller bore sizes (≤ DN50 / NPS 2"), perfectly suited for medium to high-pressure scenarios.
Flange Facing: Options include Raised Face (RF), Flat Face (FF), and Ring-Type Joint (RTJ), meticulously selected to accommodate varying gasket and application requirements.
Flange Standards: Our products are meticulously crafted to adhere to the following standards:
ASME B16.5: Available in the most sought-after pressure classes like 150, 300, 600, and more.
EN 1092-1 (DIN): Pressure ratings include PN6, PN10, PN16, PN25, PN40, ensuring versatile application.
JIS B2220: Compliant with the esteemed Japanese Industrial Standard for assured quality.
GB/T 9113: Rigorously meets the Chinese National Standard, guaranteeing excellence.
Bolt Holes: Precision-drilled to ensure secure bolting with mating flanges, delivering unmatched reliability and stability.
3. Connection Methods:
Welding Ends: Seamlessly integrated into pipelines through butt welding, utilizing TIG (GTAW) or SMAW processes in accordance with high standards such as ASME B31.3 and EN 13480.
Flanged End: Experience the pinnacle of secure connections with our meticulously crafted flange. Utilizes premium stainless steel bolts and nuts, coupled with an array of sealing gaskets, including spiral wound, graphite, or PTFE, to seamlessly integrate with valves, equipment, and any other flanged piping systems.
