Product: 21000-00-00-150-00-02
Description: This alphanumeric code likely represents a specific model of a flexible expansion joint or bellows, commonly used in piping and ducting systems. The sequence "150" strongly suggests a nominal diameter (e.g., 150 mm, 6 inches), while the suffix codes indicate specific construction materials, end fittings, and length. Its primary function is to absorb thermal expansion, vibration, and misalignment in industrial piping networks.
Key Parameters (Specifications):
| Parameter | Specification |
|---|---|
| Model / Part Number | 21000-00-00-150-00-02 |
| Nominal Diameter (DN) | 150 mm (or 6 inches) - This is the primary size identifier. |
| Connector / Flange Type | Typically flanged ends (e.g., ANSI 150# or PN16) as suggested by common industry standards. The suffix "-02" may specify the flange standard or face type. |
| Axial Length | Varies; a standard length for this diameter might be ~230 mm. Exact length is critical and defined by the full part number. |
| Overall Dimensions | Approx. Length: 230mm (varies), Outside Diameter of Bellows: ~210-250mm (depends on convolutions and cover). Must be verified with manufacturer's drawing. |
| Weight | Approx. 8 - 12 kg, depending on material thickness and flange type. |
| Bellow Material | Typically Stainless Steel (AISI 304/316) for the corrugated flexible element. |
| Flange/End Material | Carbon steel or stainless steel, matching the pipe system. |
| Operating Pressure | Standard rating for this size: PN16 (16 bar) or 150 PSI. |
| Operating Temperature Range | -20°C to +200°C for standard elastomer seals; higher with specialized packing. |
| Movement Capabilities | Designed to absorb Axial Compression/Extension, Lateral, and Angular movement. Specific values (mm/degrees) are model-dependent. |
Primary Application Scenarios:
HVAC Systems: Connecting to chillers, cooling towers, and air handlers to absorb vibration from pumps and compressors, and to compensate for thermal expansion in large ductwork and piping.
Industrial Process Piping: Used in chemical, petrochemical, and power plants to protect pumps, turbines, and vessels from pipe stress caused by thermal growth, pressure changes, and equipment settlement.
Marine & Shipbuilding: Installed in engine room piping (fuel, cooling water, exhaust) to isolate engine vibration and hull flexing from the rigid pipe system.
District Heating & Cooling Networks: Compensates for significant thermal expansion in long underground or above-ground supply and return lines.
Compensators for Equipment: Mounted at the inlet/outlet of sensitive equipment like large diesel generators, gas compressors, or steam turbines to ensure piping loads are within allowable limits.
Critical Note: The information above is based on standard industry interpretations of such numbering systems for expansion joints. For engineering, procurement, and installation, it is absolutely essential to obtain and use the certified dimensional drawing, pressure/temperature ratings, and movement capacity charts from the manufacturer (e.g., Witzenmann, Flexider, Senior Flexonics) for the exact part number 21000-00-00-150-00-02. Incorrect application can lead to system failure.
