The Unison CT-38 tube and pipe end coning and thread-rolling machine
Finished product
Unison Ltd. offers a precise tube and pipe end coning and thread-rolling machine.
Called the Unison CT-38, the machine has been developed with a particular focus on creating the gas-tight seals required for many of the components used in the growing hydrogen energy sector, as well as in the global oil and gas industry. Unison anticipates the CT-38 will also be of interest to organizations in the hydraulics, lubricants, liquid processing and chemical industries.
Depending on customer requirements, the CT-38 will cone and thread medium pressure (up to 20,000 PSI), high pressure (up to 60,000 PSI) and ultra-high-pressure (up to 150,000 PSI) connections in stainless steel and exotic alloys, such as thick-wall super duplex pipes. The maximum tube diameter the machine will accept is 38 mm (1-1/2").
Machine set-up time is rapid, and the coning/threading cycle typically takes around five minutes to complete, including tool changes, for a one-off component. Additionally, as a further time-saving benefit, in many cases the tube or pipe can be pre-bent before threading and coning takes place. As the quality of the coning surface is critical to ensure a successful seal, the CT-38 machine completes an "overturn" clean-up process following thread rolling and before precision coning occurs. Thread rolling produces a stronger thread than thread cutting and also generates zero swarf.
"Traditionally, the coning and threading of exotic tube-particularly when working with larger diameters-has been cumbersome and slow, often involving labor-intensive processes," said Steve Chambers, Unison's Sales Projects Manager. "Looking for a faster, easier alternative to the solutions currently on the market, a number of our energy-sector customers-users of our all-electric bending technologies and tube washing machines-approached us to ask if we would consider developing a high-capability coning and threading machine. Taking on board their requirements, as well as their frustrations with existing coning and threading technologies, we developed the CT-38."
Able to cone and create left-hand and right-hand threads in tube and pipe as little as 6.35 mm in diameter (1/4") up to the maximum diameter of 38 mm (1-1/2"), the CT-38 is largely constructed of aluminum and stainless steel to ensure it is able to easily withstand operation offshore as well as in other harsh, often corrosive environments. Unison's easy-to-use 15" touchscreen control provides intuitive programming and infinite recipe storage, while tooling changes between coning and threading cycles are simple and straightforward.
