Wachs ECC External Casing Cutter utilizes DynaPrep MDSF Split Frame technology to cut casing conductors externally above the wellhead. The ECC split frame mounts around the exposed casing OD above the wellhead and simultaneously cuts and chamfers prior to fitting the BOP. Ring sizes are available for most grades and weights of the exposed external casing (or drive pipe/conductor) up to a 14in (356mm) diameter.
The ECC takes advantage of the wide range of standard Genuine Wachs Tooling. The ECC kit includes a right angle pneumatic drive, ATM Air Treatment Module and Front Drive Pinion Housing. Remote hand held controls via the ACM Air Control Module are optionally available.
ECC kits are available in four standard ring sizes, featuring interchangeable tool slides and machine drives to cut and bevel all wellhead casing grades, sizes and weights from 4.5in to 13 3/8in OD (with larger sizes available by special order). The ECC is portable, compact, lightweight and requires minimal axial and radial clearance. A single operator can setup and machine the casing for minimal open time.
