Piping Technology & Products, Inc. designed and fabricated 24″, chrome-moly, three-bolt clamps with horizontal guide stanchions for a 765 MW natural gas-fired combined cycle facility in Mexico.
These clamps, in conjunction with variable springs, will allow for vertical and axial pipe movement while restricting lateral movements. They were made for 24″ OD pipe from 1-1/2 x 9″ stock material. Based upon design considerations, the clamp “E” dimension, from pipe centerline to outer load bolt, was 25″. The clamps were designed for operation at 1065°F and per customer-supplied information, the vertical design load was 1,848 lbs and the maximum lateral load was 19,207 lbs.
The clamp plates are made of A387 GR. 22 plate material, stanchion pieces of A335 GR.22 pipe and the side stop plates of carbon steel.
