SIEMENS 16-3/4" Product Description

The SIEMENS 16-3/4" is a large-size industrial process flange designed for heavy-duty pipeline and vessel connection in oil & gas, chemical and power industries. This industrial process flange complies with ASME B16.5 standard and supports high pressure rating for large bore piping assembly. This industrial process flange adopts forged carbon steel or stainless steel raw material to deliver high mechanical strength and resist heavy load stress. This industrial process flange features precise bolt hole positioning and flat sealing face, ensuring tight assembly and reliable sealing performance under extreme operating conditions.

This SIEMENS 16-3/4" flange can be matched with pressure transmitters, level instruments and large control valves for process measurement points. Its precision-machined flange sealing face eliminates uneven contact and reduces the risk of medium leakage at high temperature and pressure. The flange sealing face is processed with strict surface roughness control to fit gaskets steadily and maintain long-term sealing integrity. The flange sealing face can be customized into raised face, ring type joint or tongue and groove types for different hazardous media. The corrosion-resistant coating of the flange sealing face protects the mating surface from oxidation and medium erosion during long outdoor operation.

The flange structure supports easy field installation and disassembly for instrument maintenance or pipeline overhaul. Secure pipeline instrument connection firmly links field measurement instruments to process vessels and large diameter pipes. Stable pipeline instrument connection transfers process pressure and medium to sensing elements without signal distortion or leakage. Standardized pipeline instrument connection simplifies spare part management and shortens project delivery cycles for EPC contractors. Robust pipeline instrument connection withstands pipeline vibration and thermal expansion, preventing loosening of bolted joints during continuous plant running.

The SIEMENS 16-3/4" flange undergoes full material inspection and hydrostatic pressure testing before factory delivery to guarantee quality compliance. Multiple wetted material selections including A105, 316L and alloy steel are available to adapt to corrosive gas, crude oil and high-temperature steam media. It is widely used for large tank level transmitters, differential pressure flow assemblies and pipeline pressure monitoring points. The large bore design allows sufficient medium flow and reduces turbulence interference for accurate process readings. With reliable mechanical performance and standardized dimension, the SIEMENS 16-3/4" industrial process flange serves as a critical connecting component for heavy industrial automation and process measurement projects worldwide.
