Truncated cone strainers — Product view
The truncated cone retains a sloping wall while ending at a finite small diameter. Large diameter, small-end diameter and axial length define the taper; the end closure is a separate drawing item. A perforated end adds screening area, while a solid end redirects flow through the sidewall. The longitudinal seam and end joint form the complete load-bearing shell.
The mounting ring seats between pipe flanges, with gasket contact outside the active screen opening. The drawing identifies the end-closure type, liner attachment, flow direction and clearance to valves or instruments. Inspection checks taper dimensions, end-joint continuity, ring flatness and the unobstructed flow path. The commissioning record tracks differential pressure and schedules removal when flushing is complete.
| Feature | Drawing and operating definition |

| Frustum | Large diameter, small-end diameter and axial length |
| End closure | Perforated or solid end; end-joint construction |
| Mounting | Ring, gasket contact, flange gap and equipment clearance |
| Media and service | Shell holes, optional liner, flow arrow and pressure-drop monitoring |

Round support-hole sizes are stated in inches with exact millimetre conversions using 1 in = 25.4 mm. Hole pitch, sheet thickness and solid mounting lands complete the support geometry. The optional woven liner has its own mesh and wire specification.
| Mesh count / inch | Wire diameter (mm) | Clear aperture (mm) |
|---|---|---|
| 20 | 0.406 | 0.86 |
| 40 | 0.254 | 0.38 |
| 80 | 0.140 | 0.18 |
| 100 | 0.102 | 0.15 |
Choose the woven liner by its mesh, wire and clear aperture. The perforated support and the finer filtering cloth have separate openings; support holes provide backing and drainage, while the cloth controls the selected particle opening.

The screen captures construction debris during flushing and is removed after commissioning.
The upstream screen intercepts debris before it reaches the pump inlet.
