PT&P Aids in the Immediate Replacement of over 160 Pipe Shoes
PT&P was called on by an energy center in Oklahoma to inspect failing pipe shoes designed for temperatures ranging from 650 to 1065 °F supplied by another company. After thorough inspection, PT&P’s field service representatives concluded that the problem was due to the existing pipe clamps’ inability to firmly grip the pipe during expansion. This exposed the pipes to atmospheric moisture, resulting in both heat loss and deterioration. To alleviate the situation, PT&P designed secured pipe clamps that were bolted and torqued such that the entire pipe shoe would move with the pipe’s expansion. PT&P’s field service team also provided on-site installation of the replacement pipe shoes. The entire process involved stripping of the existing damaged insulation, removal of the failing supports, and installation of new pipe shoes and insulation.
Pipe Shoes in the Field
Over 160 pipe shoes were engineered, manufactured, and installed for this energy center. The fabricated pipe shoes, designed for pipe sizes ranging from 12 to 28″ in diameter, are equipped with special base plate and slide bearing plate combinations which allowed axial movement from 1/2″ to 7″ and lateral movement up to 10 1/2″. In addition, they were designed to support a maximum vertical and lateral load of 38,000 lb. and 7,600 lb. respectively.

PT&P Aids in the Construction of an Oil Refinery
Piping Technology & Products, Inc. has designed and manufactured over 177 tons of supports for the Chad/Cameroon Development Project in Chad, Africa. Adjustable Base Supports designed to support pipe size ranging from 3 to 18″ in diameter were one type of the many supports fabricated for this project.
Each of the hot-dipped galvanized pipe stands has an 8″x8″ base plate and a midrange height of 12″. The pipe stands allow for a maximum travel of +/- 3″. These supports provide for easy adjustment in the field when supporting pipe trunnions on concrete pads or foundations. In addition, these pipe stands have a major advantage when the exact installation heights are not known at the remote job site.
Other supports including constants and variables spring hangers, rigid rod hangers, structural steel, FRP pads, and pre-insulated pipe supports were also manufactured in a range of different specifications and materials.
