New casing cutter unveiled by Hydratight to serve upstream oil and gas market

24 March 2017

A range of machining tools developed by pipeline joint integrity specialists Hydratight is set to be released to upstream oil and gas markets globally.

The company has unveiled its External Casing Cutter (ECC) and Internal-External Casing Cutter (IECC) to allow customers to work above and below wellheads, using tooling which is lighter, more accurate and with a larger model range than currently available in the market.

​Hydratight has designed both sets of tools for ease of operation, strength and flexibility. They will be used in well completion activities by drilling contractors, decommissioning specialists, valve OEMs and service providers.

The ECC and the IECC are backed up by the company’s comprehensive technical support.

The launch follows market demands for greater choice of high quality wellhead casing cutting tools compatible with a variety of pipeline sizes.

Lotus Zhou, Product Marketing Manager – Machining, said: “There is a strong drive in the oil and gas market for high quality, reliable tooling for work on wellheads. We’ve designed our new range for some of the most critical of subsea applications - wellhead completions.

“The ECC has the flexibility of five models, all compatible with our Narrow Body Clamshell range. They are reduced weight and low profile, which will be attractive to our customer base.

“The all new IECC has pneumatic and hydraulic drive options and will cut to an internal depth of 50” (1270mm) from the wellhead flange.”                                                                                                                                                                                                 

The ECC is equipped with a bi-directional drive, a low-profile motor and mount configuration, and can be inverted for flush mount applications. The drive motor can be adjusted if obstructions are present. It covers pipe sizes from 3.2” (114.3mm) to 32” (812.8mm).

The IECC attaches to Hydratight’s NB Clamshell and can internally sever and bevel for a variety of applications. The tool’s spark-free cutters offer increased safety by eliminating the need for flame cutting. Cold cutting produces accurate and repeatable weld-preparations on wellhead casings.
