The necessary steps for installing all expansion joints shall be pre-planned. The installers shall be made aware of these steps as well as the installation instructions furnished by the manufacturer. The most critical phases of the expansion joint installation are as follows.
Care shall be exercised to prevent any damage to the thin bellows section, such as dents, scores, arc strikes and weld spatter.
No movement of the expansion joint (compression, extension, offset, rotation and especially torsion) due to piping misalignment, for example, shall be imposed which has not been anticipated and designed into the movement capability of the expansion joint. If such movements are imposed, they can result in system malfunction, damage to the bellows or other components in the system. Specifically, cycle life can be substantially reduced, forces imposed on adjacent equipment may exceed their design limits, internal sleeve clearances may be adversely affected, and the pressure capacity and stability of the bellows may be reduced.
Any field pre-positioning shall be performed in accordance with specific instructions which include both the direction and magnitude of the movement.
Anchors, guides and pipe supports shall be installed in strict accordance with the piping system drawings. Any field variances from planned installation may affect proper functioning of the expansion joint and must be brought to the attention of a competent design authority for resolution.
The expansion joint, if provided with internal sleeves, shall be installed with the proper orientation with respect to flow direction.
After the anchors or other fixed points are in place and the piping is properly supported and guided, the expansion joint shipping devices should normally be removed in order to allow the expansion joint to compensate for changes in ambient temperature during the remainder of the construction phase.

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. View the full article.
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.
The max temperature for the galvanized finish isup to 350 degrees F.
The ladders and platforms were designed to be installed on a 90′ tall pressure vessel. The ladders were fabricated from carbon steel and ranged in size from 5′ to 38′ in length. The vessel platforms were also fabricated from carbon steel and measure up to 16′-6″ in diameter.

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.

This F-type variable spring support was customized with a wire rope isolator for a facility located in Canada. The variable spring was designed for a load of 12,000 lb. The wire rope isolator is essentially a 1.25″ diameter stainless steel rope looped eight times between two chemically conversion coated aluminum alloy retaining bars. The wire rope isolator is effective in vibration isolation and energy absorption.

Cryogenic pipe supports, ranging in diameter from 6″ to 38″, were designed to support and insulate piping in an LNG receiving and regassification plant. The “cold shoe anchors” were designed for temperatures down to -260°F and a load range of 26,000 lb. to 210,000 lb. A combination of high density polyurethane foam (PUF) and Permali® was used for the insulation. The center stops that are welded to the process pipe were built from 304 stainless steel, and carbon steel was used for the remainder of the shoe.

A total of 90 variable spring supports were designed and manufactured to support pipe lines in a gas storage facility in Abu Dhabi. The pictures above show PTP-4 Double Spring B-Type, PTP-6 Triple Springs B-Type, PTP-1 Triple Springs D-Type, and PTP-4 Double Springs F-Type, (also known as F-Cans). Load capacities range from 1,000 lb. to 45,000 lb., and movements range from 3/8″ to 3″. A two-layer custom paint was applied over the hot-dip galvanized finish to protect against a severely corrosive environment. Travel stops were chained to the spring can housing, so they can be reused during plant shutdowns. Load and quality assurance tests were performed on all the supports prior to shipment.

This week’s feature is on mechanical snubber assemblies custom designed for an oil refinery in California. This project included twenty mechanical snubber assemblies with load ratings from 16,000 lb. to 40,000 lb. and lengths ranging from 65-1/2″ to 103-1/2″. Some of the snubbers were designed to double the standard stroke (up to 12″) by using two MSA-10 sized snubbers back-to-back. All the assemblies were custom designed by adding a carbon steel pipe extension piece. Load tests were performed and the assemblies were shipped in just under four weeks.
