Subject: Pipe Support and Expansion Joint Field Examples and Case Studies

Date: Thursday, December 8, 2011

PT&P's field service division is available 24x7 in the case of an emergency situation or for a scheduled shut down. In this Webinar we explore the details of actual case studies focusing on various signs that indicate if a particular support needs replaced or adjusted. The presentation also covers projects that brought on new standard designs and custom designs for specific applications. And lastly, it includes valuable additions and procedures that extend the typical life span of a pipe support.

These custom heavy duty Fig. 43 yoke u-bolt pipe clamps are designed for manifold piping in a Continuous Catalyst Regeneration plant in Mexico. The yoke clamps are for a 36" diameter pipe size and are fabricated from A240 Grade 316 stainless steel. They are designed to support a load of 33,731 lb. and temperatures up to 1100°F. PT&P supplied a total of 16 assemblies, comprised of yoke u-bolt clamps and E-type constant springs, for this project.

These custom fig. 2110, size 8 sway struts are for a liquid filters manufacturer located in Mississippi. Both sway struts have a 128,000 lb. load capacity and are fabricated from carbon steel with a hot-dipped galvanized finish. The sway struts measure 68-5/8" long and have a 4" diameter rod size. A load test was performed prior to an expedited shipping schedule of 1-1/2 weeks.

Do you have a plant turnaround scheduled or planning one in the near future? PT&P is prepared to be there for you throughout the entire process. From planning, to execution, and follow-up, we have what it takes to accomplish a successful plant turnaround.

Prior to Your Turnaround: - Call our field service team to assist with plant walk-downs to assess your plant for maintenance, repair or replacement of pipe supports and expansion joints - Contact our quotations department for immediate pricing on pipe supports, expansion joints, or auxiliary steel needed during the turnaround. - Consult our experienced engineers for guidance on support placement, materials, finishes, etc. to ensure optimum life of the supports.

During Your Turnaround: - Use our field service team to guide you through installation, start-up, and replacement to safely and efficiently handle your turnaround. - For quick delivery, PT&P stocks over 1500 bellows, over 100,000 lb. of insulation materials, over 30,000 spring coils, and over 1 million pounds of standard items

Post Turnaround: - Receive training to monitor the supports, and identify potential failure, in order to prevent unplanned turnarounds in the future. - Learn correct size and selection of pipe supports and expansion joints per application for any post-turnaround resolutions. - Call on our field service team to develop a data book of existing pipe supports and expansion joints and their conditions in order to identify potential maintenance issues in upcoming turnarounds.

A rectangular metal expansion joint was refurbished  on an emergency   basis for a local chemical plant. Upon arrival, it was acid washed and   dye-penetrant examined for any cracks.  View the full Article

U.S. Bellows, Inc. refurbished two pressure balanced elbow expansion joints with a quick turnaround for a power generation plant during outages.   They are designed for high pressure turbine crossover piping. The first 54" outside diameter expansion joint leaked from a crack in the bellows   causing an unscheduled outage.  View the full article.

This expansion joint was received in the morning and shipped to the customer the very same day. The bellows, liner and cover were replaced and the carbon steel parts were sand blasted, cleaned and painted. A dye-penetrant test and hydro-test to 518 PSIG were performed prior to shipment.

This expansion joint was received in the morning, refurbished by adding new bellows and limit rods, and then shipped the very same day. New 321 stainless steel bellows were fabricated and the existing flanges were reused by sandblasting and then painting for corrosion protection. View the full article.

The slide plates are comprised of 1/4" thick PTFE, 25% glass filled slide plates bonded to 1/8" A240 grade 316 L stainless steel backing plates. Stainless steel was used for better resistance to corrosion and longevity. The assemblies measure 83" long by 20" wide and will be installed underneath a bridge. A total of 16 slide plates were fabricated and designed for a pressure of 500 psi at ambient temperature. PTFE, 25% glass filled material provides a low coefficient of friction, is easy to install, does not require surface treatments, or grouting, and is unaffected by weather conditions.

These figure 200 U-type constant springs were fabricated from A-36 carbon steel and range in size from 30-1/2" to 41" in height, 25" to 31" in width, and 68" to 80" in length. These are horizontal constants designed to support piping from below where the base plate is bolted directly to the top of the steel or the foundation using anchor bolts. Loads range from 9,000 lb. to 42,000 lb., and vertical movements range from 6" to 11". All the constants went through standard load and travel testing per MSS Standards prior to shipment.
