Piping Technology and Products Inc. PT P has for some time been performing surveys and assessments in accordance with part H of Par. These assessments are helpful in identifying, sagging lines, deformation of supports, and damage caused by upset conditions, andor incidents, attributable to operational malfunctions, dynamicthermal or hydraulic events. PT P has been performing this service for many power generation companies. Preparation of documentation, retrieval and compilation of files for a CPS assessment, has just been completed for a major U. S power generation company. Ten large power plants were involved, and the original predominantly high energy pipe support drawings, all engineered and designed by PT P, were retrieved from PT P archives dating back ten years.
