Sonic Sampling & Supply offers seven different clamp models from the product line of Italian manufacturer Sgolastra & Giampaoli for the North American market. Hydraulically operated clamps accommodate various pipe and casing diameters and different torque requirements, and can be used on rotary, sonic and direct-push rigs. The smallest clamp is for pipe diameters from 1 inch to 3.5 inches, and the largest model can handle pipe from 3.1 inches to 23.6 inches in diameter. The clamps may be mounted at any spread distance between each clamp, and can be stacked or mounted singly for use as a holding clamp.
