E.H. Wachs

Wachs EICC External Internal Casing Cutter Kit is designed to cut and chamfer the casing internally below the wellhead, required for specific BOP installations. It is used in combination with an ECC which makes the external cut required before installing the EICC. The ECC cuts up to 7in through 13 3/8in API casing, and utilizes standard Wachs tooling for external severing. Once the external cut is made, the MDSF split frame from the ECC Kit serves as the drive platform for the EICC.
 
A wellhead adaptor is required to mount the MDSF, either our Universal adapter or a custom adapter built to your specifications, serving as the mounting point between the wellhead and the MDSF. The EICC is assembled to the MDSF and lowered into the casing, and can be configured to cut down to a depth of 60in (1524mm). The EICC utilizes a casing cutter tooling holder and insert arrangement for a lower cost per cut.  A reversing air motor is required and part of the EICC Kit, running forward to advance the tooling, then backwards to retract the tooling prior to extraction and completion.

E.H. Wachs WCR Weld Crown Removal module for the DynaPrep MDSF® provides a low clearance solution for removing pipe weld crowns, in the field or fab shop. This module attaches to the DynaPrep MDSF Split Frame without any modifications needed. The WCR module advances the tooling axially as the MDSF, serving as the drive platform, rotates radially.

With a 3.75in ((95mm) tooling stroke and a 2.5in (63mm) slide mounting stroke, the WCR offers up to a total of 6.25in (158mm) of axial stroke, large enough for even the widest weld crown. The module can be positioned radially at any of six mounting positions, giving a radial mounting range of 3in (76mm) for maximum versatility.
