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.

Examples:

Metallic Expansion Joint Refurbished in 2 Days

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

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

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. View the full article.

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.

Big Ton Spring Supports for a Chemical Processing Plant

A total of 18 big ton springs of various sizes were fabricated from A516 Gr. 70N carbon steel. The big tons were designed in a rectangular configuration in order to match the existing vessel saddle supports and the concrete foundation below the springs. PTFE, 25% glass filled slide plates will be welded on the load flanges to allow horizontal movement in addition to the vertical movements specified. The largest of the big ton assemblies has an operating load of 79,000 lb. with a travel of .706″ down.

22″ Dia. Riser Clamps

All four riser clamps are manufactured from A-36 carbon steel plates and are coated with red oxide primer for rust prevention. They are 22″ in diameter with each plate measuring 2″ thick by 12″ wide by 65″ long. Each riser clamp is capable of supporting loads of up to 38,000 lb. and will be used in a power plant to support “downcomer” lines.

72″ I.D. Cryogenic Insulated Supports

PT&P manufactured 72″ dia. insulated supports for temperatures as low as -260°F. The insulation is multi-layered comprised of polyurethane foam with a density of 20 PCF, a vapor barrier, an aluminum metal jacket, and acoustic pads. The acoustic pads are installed around the cold shoe to absorb vibration. The base and bearing plates are fabricated from carbon steel. The shoes will be used to support and insulate piping in a receiving & regassification plant and refinery.

Cryogenic Insulated Supports with Acoustic Pads

The operating temperature for these cryogenic shoes ranges from -290°F to 90°F. They are designed for 56″ diameter pipe and are capable of supporting loads up to 40,000 lb. The insulation is multi-layered comprised of 20 PCF polyurethane, a vapor barrier, an aluminum metal jacket, and acoustic pads. The acoustic pads are installed around the cold shoe to absorb vibration. The base and bearing plates are fabricated from carbon steel.

Billet Style Clevis

The clevis and turnbuckle pictured are each fabricated from individual solid pieces of 304H stainless steel. The 304H material, which has a maximum carbon content of 0.06%, was required because these items are designed to be used in an environment with temperatures up to 1000ºF. The customer’s specifications mandated that no welding would be allowed on either the clevises or turnbuckles. Additionally, no forgings were readily available, so blocks of 304H stainless steel were utilized in this design.

Billet Style Turnbuckle

Both the clevises and turnbuckles are made to accommodate rod diameter ranges between 1-1/4″ to 1-3/4″. These components have a maximum load capacity of 18,600 lb. The clevises measure 3″ thick x 5-1/4″ wide x 10-5/8″ tall. The turnbuckles measure 2″ thick x 4″ wide x 9-1/4″ tall. Prior to fabrication, each component was modeled using finite element analysis to determine that stress levels are within the acceptable range.

4″ to 14″ Diameter Spectacle Blinds for Process Piping

4″ to 14″ Diameter Spectacle Blinds for Process Piping

Sweco Fab, Inc., a division of PT&P, fabricated a variety of six spectacle blinds that will be used for selective line isolation. The spectacle blinds are fabricated from A516-70 carbon steel with sizes ranging from 4″ to 14″ diameter and per ASME B16.48 code. The function of a spectacle blind is to allow a line to be in either full shut-off mode or full flow mode, depending on which side is being utilized. Spectacle blinds are a lower cost alternative to double block and bleed valves where OSHA requires positive isolation of piping segments for safety reasons.
