W1-M Slip Hanger, Manual Seal Casing Hanger
The W1-M Casing Hanger is the preferred standard manually energized slip-type casing hanger designed to suspend medium casing loads in the W2 and W2-BP casing heads and spools.
Features –
- Two-piece assembly bolts quickly and easily around the casing
- Each half is lighter weight and less cumbersome and awkward than manipulating a hinged hanger
- Packoff is manually energized as cap screws are tightened down to compress the seal
- Guide pins maintain alignment of slip segments during assembly and installation
- Designed in sizes to accommodate the full API tolerance range for casing OD
- Supports weight equivalent to 50% of pipe body yield (PBY), plus test pressure at either the flange rating or 80% of pipe collapse, whichever is less
