Key Features & Construction
1. Material:
Expertly fashioned from premium austenitic stainless steel, the available grades include:
304 (1.4301 / UNS S30400): A highly versatile grade celebrated for its exceptional resistance to corrosion, flexibility, and weldability. Ideally suited for diverse applications such as water systems, steam lines, food processing, and environments with mild chemicals.
316/316L (1.4401/1.4404 / UNS S31600/S31603): Enhanced with molybdenum, this grade is engineered for superior resistance to chloride-rich settings, pitting, and crevice corrosion. Perfectly crafted for chemical processing, marine, pharmaceutical, and other high-corrosion-prone environments. The 316L variant offers superior weldability and safeguarding against intergranular corrosion.
Material Properties: Offers unmatched resistance to both corrosion and oxidation, paired with outstanding strength across varied temperature ranges. Its superior ductility and toughness ensure long-lasting performance and reliability.
2. Design:
Tee Body: Features a run inlet, a run outlet, and a perpendicular or angular branch outlet. Available in equal (straight) or reducing configurations, with the standard branch angle calibrated at 90° for optimal flow management.
Welding Ends: Typically situated on the run ends, these are meticulously prepared with beveled ends (e.g., V-groove) for butt welding (BW) to the pipeline. This guarantees maximum strength and a leak-proof seal, essential in high-pressure, high-temperature, or high-vibration situations.
Flanged End: Generally located on the branch outlet, and occasionally on run ends, it features a standard stainless steel flange for optimal connectivity.
Flange Types: Prominent choices include:
Slip-On Flange (SO): Best for low to medium pressure applications, providing ease of installation.
Weld Neck Flange (WN): Ideal for high-pressure/temperature conditions or cyclic loading, its tapered hub is meticulously designed to maximize stress distribution, making it the most dependable type.
Socket Weld Flange (SW): Tailored for small bore sizes (≤ DN50 / NPS 2"), and adept at handling medium to high pressure.
Flange Facing: Options include Raised Face (RF), Flat Face (FF), and Ring-Type Joint (RTJ) - each carefully selected based on specific gasket and application needs.
Flange Standards: Adheres to the following benchmarks:
ASME B16.5: Offers pressure classes such as 150, 300, 600, and more for extensive applicability.
EN 1092-1 (DIN): Provides common pressure ratings of PN6, PN10, PN16, PN25, and PN40.
JIS B2220: Conforms to the Japanese Industrial Standard.
GB/T 9113: Complies with the rigorous specifications of the Chinese National Standard.
Bolt Holes: Precision-drilled with expertise to ensure impeccable bolting to corresponding flanges.
3. Connection Methods:
Welding Ends: Seamlessly butt-welded to pipelines using advanced TIG (GTAW) or SMAW techniques, ensuring strict compliance with prestigious codes like ASME B31.3 and EN 13480, for unmatched joint integrity and performance.
Flanged End: Securely connect with stainless steel bolts and nuts, enhanced by a high-performance sealing gasket such as spiral wound, graphite, or PTFE, ensuring leak-proof connections to valves, equipment, or other flange systems.
