Stellar Couplers

Details

The Star Coupler with Wheel Handling is a piece of equipment designed to couple the heads of two subsequent pipelines, keeping them in place during the welding process. It consists of two opposite rays (two stars), supplied with adjustable heads lower extremities.

Star Couplers with Wheel Handling are available in sizes ranging from 20 ’’ to 56’’: the maximum size is roughly equal to its nominal size, for a width of about 300 mm; the weight varies from about 50 to 135 daN.

Because of the limited weight, the Band can be moved manually. But, if it’s necessary to move it using lifting equipment, it is sufficient to hook it through a lifting strap at any point of the frame itself.

The capacity of the lifting equipment must be at least twice the weight of the Coupler to guarantee safe handling and positioning.
