Profile: Carpenter and Paterson Ltd. specializes in the design and manufacture of pipe suspension equipment, and steelwork fabrications. Our products include spring supports, steelwork fabrication, hydraulic shock arrestors, spring sway braces, and ancillary equipment. Spring supports are used for supporting piping and related components which are subject to thermal expansion displacements. These types of spring supports are usually manufactured in standard carbon steel; but low temperature, and stainless steels are utilized for special environmental conditions. Our hydraulic shock arrestors are developed to protect pipelines and equipment from the effect of shock loads generated by rapid valve closure or seismic shock conditions.
