Do you have a plant turnaround coming up?

October 24th, 2011 Comments off

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.

Refurbishment of 54" Pressure Balanced Elbow Turbine Crossover Expansion Joints

Refurbishment of 54" Pressure Balanced Elbow Turbine Crossover Expansion Joints

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.

4" Single Expansion Joint

4" Single Expansion Joint

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.

Same Day Turnaround Service on an 8" Single Expansion Joint

Same Day Turnaround Service on an 8" Single Expansion Joint

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.

Dye Penetrant Testing Before and After Forming The Bellows

September 6th, 2011 Comments off

We perform dye penetrant testing on all bellows longitudinal seam welds before and after forming the bellows. The test is performed to insure there are no weld defects such as surface cracking or weld discontinuities. The weld surface is thoroughly cleaned and a red penetrant dye is applied to the surface of the weld and allowed to soak for a period of time. The dye is then removed and a white powder is sprayed on the weld surface that performs a blotting action. An indication of the dye with a white background characterizes the weld surface discontinuities of the bellows longitudinal seam weld. This testing before and after the bellows forming process ensures a sound quality bellows seam weld.
