Specialist manufacturer of pipeline equipment

CRC-Evans is a leading manufacturer of equipment and a supplier of services to the pipeline industry. The equipment ranges from pipe bending machines to pipe handling and support equipment, and from pipe facing and bevelling machines to internal line-up clamps. The company also build double jointing systems for use on land and offshore. A highlight of the company’s range is automatic welding systems for land and offshore pipeline construction. This equipment line includes single- or dual- torch welding systems, internal welding machines, copper backup clamps and precision pipe facing machines. These systems have been designed, tested, used and continuously upgraded for more than 35 years in every type of environment. CRC-Evans have extensive experience in welding X-80, X-100 and X-120 pipes, as well as 13-Chrome, duplex, super duplex and clad pipes. The company provides a basic gas-metal- arc automatic welding system designed

to make quality girth welds while delivering high production rates. It can accommodate pipe sizes from 4-60" and wall thickness in excess of 1" (25mm). The system consists of three major components. Pipe facing machines produce a narrow groove compound bevel to assure near perfect joint fit-up for every weld.

› CRC-Evans offer a range of automatic welding systems for land and offshore pipeline construction

The combination internal welder/line- up clamp travels inside the pipe to align and clamp joint ends together, and then automatically welds the root bead from the inside. External welding machines make the outer girth weld. Travelling on steel bands fixed to the pipe, the machines accurately complete the weld in a series of passes. The company also offers flux-core and pulsed gas-metal-arc systems. In addition to the company’s extensive onshore experience, the company has

designed and built state-of-the-art automatic welding equipment. These offshore systems allow the user to maximize productivity from a limited number of welding stations. This boosts the speed of operations, maintains the highest level of quality, and enables the pipeline to be built on schedule.
