Constant Furnace Springs
 
Join us for this Webinar focusing on the unique design aspects of pipe supports and expansion joints operating in furnace applications. See how these non-standard designs impact the overall construction and fabrication processes. Learn the differences between standard supports and those specifically used in furnace applications. View the in-depth testing processes and learn what to watch for during inspection and maintenance intervals. The featured presenter, Jerry Godina has over 13 years experience as a pipe support designer and manages PT&P’s engineer training development program. He also inspects existing supports, consults on site remediation projects and oversees installation on a regular basis.

Hydraulic Snubbers Designed for a Geothermal Facility

Posted by Sylvia Ibarra on Mar 19, 2012

Hydraulic Snubbers Designed for a Geothermal Facility

Fronek Anchor/Darling Enterprises, a division of PT&P designed and fabricated hydraulic snubbers for a geothermal facility in California. The Fig. 510 AD snubbers ranged in size from 34-3/4" to 37-5/8" piston-to-piston and were designed for a 50,000 lb. maximum load, 5" cylinder size and a 6" stroke. The Fig. 511 AD snubbers ranged in size from 56-15/16" to 59-5/16" P-P and were designed for a 20,000 lb. maximum load, 2-1/2" cylinder size and a 6" stroke. Hydraulic snubbers are designed to protect the piping system when a sudden, heavy load is applied (such as an earthquake of high intensity), which can cause serious vibrations leading to complete destruction. A custom three-bolt pipe clamp fabricated from carbon steel was designed to fit in a limited space. A cycle test throughout the full stroke from zero to fully extended was performed prior to shipment.

7 Ways to Extend the Lifespan of a Hydraulic Snubber

Posted by Sylvia Ibarra on Mar 09, 2012

Follow these 7 steps below to maintain and extend the life span of your hydraulic snubber.

Hydraulic Snubber Assemblies for a LNG Processing Facility in Peru

1. Observe the fluid level to make sure there is sufficient fluid for the snubber to operate

2. Check for leaks - If the fluid level is decreasing, determine the cause and effect remedial action.

3. Check the condition of the load pins and spherical ball bushings. Apply a high pressure grease for long-term benefits.

4. Check the condition of the exposed portion of the piston rod. Check for scoring, paint or other physical damage.

5. Check the condition of the piston rod wiper. Verify that it's in position and working effectively.

6. Check for evidence of abuse like welding arc strikes, bent or dented parts, scratched paint, etc.

7. Finally, check the overall physical appearance. This encompasses all of the above.

ASME Defines New Inspection Criteria for High Energy Pipelines

Posted by Sylvia Ibarra on Feb 13, 2012
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.

High Temperature Pipe Supports for a Carbon Manufacturing Plant

Posted by Sylvia Ibarra on Jan 30, 2012

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.

PTP-1 F-Type Variable Spring Assemblies

Posted by Sylvia Ibarra on Dec 19, 2011
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".
