Utilizing specialized long reach equipment, C&J has the ability to clad the inside diameter of full lengths of pipe up to 60 ft long. This process requires the use of high definition, specialized video monitoring equipment in order to view the welding. These cameras require high flow coolant chillers to order to protect the equipment from extreme heat inside of the pipe. C&J Cladding has spent years developing custom accessories in order to make this process repeatable and provide the highest quality. In addition to the capability to clad the ID of pipe, C&J Cladding also has developed specialized NDE equipment in order to perform visual and liquid penetrant examination on the inside of the clad pipe. This machine also has high definition video equipment designed to measure any defects found using calibrated software. Finally, all equipment has the ability to record the video so any customer can be provided with documented evidence of the welding and inspection.
GTAW Pipe Cladding – The GTAW process for pipe cladding provides the highest quality, in addition to the capability to clad pipe with as small an inside diameter as 4.5″ for pieces up to 60′ in length. There are very few processes and techniques available to clad this small of a diameter and C&J has created cutting-edge accessories in order to make this process repeatable. This process also utilizes duel welding heads so that two layers of cladding can be applied in a single pass which helps improve efficiency and price. For even smaller applications we have developed a process to clad down to a 2″ inside diameter with a 10′ limitation on length.
SAW & GMAW Pipe Cladding – These processes are reserved for larger diameter application where accessibility is not a concern. While these processes can be performed on a minimum diameter of 8″ it is typically reserved for applications with inside diameters in excess of 12″ and in lengths up to a maximum of 30′. These processes are also more efficient than GTAW cladding which helps reduce pricing for the right applications.
There are 14 Welding Procedures Developed for Pipe Cladding
