These plate-type slip-on flanges are fabricated from steel plate; the pipe passes through the flange bore and is joined using a fillet weld. Featuring a simple and economical design, they are primarily used in PN-rated low-to-medium pressure utility systems and general industrial piping.
Unsere Flansche, Rohrbögen und Armaturen werden mit fortschrittlicher CNC-Ausrüstung und bewährten Prozessen hergestellt und liefern genaue Abmessungen, stabile Dichtungsleistung und zuverlässige Installation für anspruchsvolle industrielle Anwendungen.
Standards: Compliance primarily follows GB/T 9124.1-2019 (PN series and mating flange dimension standards); do not equate these directly to ASME B16.5 forged flanges without verifying the material and manufacturing process.
Structure: Plate-type slip-on flange; specifications must include DN, PN, flange outer diameter, bolt hole spacing, number of holes, thickness, and bore diameter.
Sealing Face: Typically Flat Face (FF) or Raised Face (RF); selection is determined by the gasket system and mating flange requirements.
Material: Plate materials such as carbon steel or stainless steel; material standards, impact requirements, and weldability must be specified in the design documentation.
Usage Limitations: Suitability for high-temperature or high-pressure service should not be inferred solely from the product name; final pressure-temperature ratings must be verified against the applicable flange standard, material specifications, and project requirements.
Ordering/Acceptance: Confirm flange type, DN/NPS, PN/Class, material group, sealing face, pipe wall thickness/bore, and bolt/gasket systems; verify each parameter against the corresponding standard dimension tables—availability of all possible combinations cannot be assumed based solely on the general scope of the standard.
