ASME Defines New Inspection Criteria for High Energy Pipelines

February 13th, 2012 Comments off

B31.1 Operations and Maintenance

According to ASME B31.1 Chapter VII Par. 140 a program shall be established for the assessment and documentation of the condition of all CPS (Covered Piping Systems) in power plants.

B 31.1 Operations and Maintenance

CPS Systems are defined in Chapter 1 Par 100.2, as systems on which condition assessments are to be conducted. This includes the following systems as a minimum.

NPS 4 and larger main steam, hot reheat steam, cold reheat steam, and boiler feedwater piping.

NPS 4 and larger systems that operate above 750°E (400°C or above 1,025 psi (7,100 kPa)

 

Other systems may be included as CPS by an Operating Company, based on their judgment. Appendix V of the code is titled ‘Recommended Practice for Operation, Maintenance, and Modification of Power Piping Systems’. This addendum is non-mandatory; however many  Power Industry operating companies’ insurance carriers are now invoking Appendix V with increasing frequency, and this is affecting conditions of their agreements with the operating companies.

Piping Technology and Products Inc. (PT&P) has for some time been performing surveys and assessments in accordance with part H of Par. 140, that requires hot and cold walk-down readings and assessment of pipe supports, operated within the creep regime of the pipe.    These assessments are helpful in identifying, sagging lines, deformation of supports, and damage caused by upset conditions, and/or incidents, attributable to operational malfunctions, dynamic/thermal 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.

Please feel free to contact us at david.baker@pipingtech.com and we will be happy to answer any of your technical questions about our survey capabilities, as well as any other engineering or field services that your organization may need.

Custom High Temperature Pipe Supports for a Granular Activated Carbon Manufacturing Plant

January 30th, 2012 Comments off

Custom High Temperature Pipe Supports for a Granular Activated Carbon Manufacturing Plant
These high temperature pipe supports have a 25″ outside diameter, and were custom designed for a granular activated carbon manufacturing plant in Hawaii. They are fabricated from A-36 carbon steel with 10″ thick high density calcium silicate insulation. The hot shoes were designed for a 4″ diameter pipe-line, temperatures up to 1,800°F and an operating load of 1,000 lb. Standard Q.C. and dimensional tests were performed prior to an expedited shipment.

Stock Upthrust Constants Modified with an Auxillary Platform

January 16th, 2012 Comments off

200 U-Type Constant Spring Supports Designed for Large Spring Coils.

These 200 U-Type constant spring supports were modified to increase their installed height by adding a secondary plate and angles, which will be welded to the structural beam. The constants range in size from 25″ to 27″ in height, 52″ to 67″ in length, and 25″ in width. Their load capacities range from 10,300 lb. to 13,000 lb. with vertical movement ranging from 3″ to 4-1/2″. All constants were fabricated from A-36 carbon steel, and went through standard load and travel testing per MSS Standards prior to shipment.

Do you have a similar application that requires upthrust constants? Get pricing today!

PTP-1 F-Type Variable Spring Assemblies

December 19th, 2011 Comments off

PTP-1 F-Type Variable Spring Assemblies

These PTP-1 F-Type variable spring assemblies fabricated from A-36 carbon steel, were custom designed to accommodate a height of 11-11/16″ while keeping the same spring rate. The F-Type variable is used to support the pipe from below and are typically mounted to concrete pads via anchor bolts or welded to structural steel. The variables are designed for loads up to 6,500 lb. and a total upward travel of 5/16″.
