164 Wide Base Sliding Insulated Supports

The hot shoes are fabricated from A-36 carbon steel with 304 stainless steel slide plates. The 18" dia. hot shoe has a maximum vertical load of 5500 lb. and the 24" dia. hot shoe is capable of loads up to 13,750 lb. All the supports in this project are designed for temperatures of up to 1200°F. In addition to the insulation, these supports are capable of sliding axially or laterally as part of the piping system.

Special U-Type Constant Spring Supports

PT&P designed a constant load support system for a fluid tank with a load of 105,000 lb. over an area of 5' W x 20' L. To prevent twisting of the fluid container, the support system is designed to allow for “level” vertical movement. This was achieved by using a special system composed of three U-Type constant units. Each unit employs two springs working in parallel with a common large base plate and a load flange to support the entire 5' width of the container.

Special U-Type Constant Spring Supports

The constants will support loads of 39,000 lb., 36,000 lb., and 30,000 lb., with a total travel of 4" in the “upwards” direction. The spring coils were coated in neoprene, and all the other major components were hot dip galvanized to inhibit corrosion. These constants were constructed primarily from carbon steel with the use of stainless steel and PTFE, 25% glass filled slide plates.

80 ft. wide Cantilevered Canopy for an International Project

Piping Technology & Products, Inc. fabricated a Cantilevered Canopy for the entrance of an International State Department building. The Canopy was fabricated using ten 20-foot long girders. These girders were connected by sixty-three structural steel members. Together, they formed the 80-foot width of the Canopy. The wooden sheathing and architectural cladding that is supported by the canopy’s inner steel structure was installed at the construction site.

The fabricated girders and structural members combined weight exceeds 33,000 lb.

Piping Technology & Products also supplied the steel framing that supports the sheathing and cladding, roof drains and piping installed inside the canopy.

This Type G variable spring was manufactured for a Petrochemical Plant in Mexico. The Type G assembly is formed by welding two standard spring assemblies to the ends of a pair of channels. This type of assembly can accommodate unusually heavy loads, and is especially convenient for avoiding interference in spaces where headroom is limited.

Each spring assembly is loaded per the client’s specification at Piping Technology and Products manufacturing facilities. A travel stop is inserted and strapped in place to maintain the load for the assembly installation. In addition to banding the travel stops, the variables for this project required chained travel stops. The base style (F-Type) variables on this project were also required to have internal guides.

At Piping Technology and Products, Inc. we use PTP-1, PTP-2, PTP-4, PTP-6 and PTP-8 to designate the five standard coil arrangements to increase the working range of travel of variable supports.

Several types of variable supports were made for this particular project. They included Type A, Type B and Type F.

These pre-insulated pipe supports were manufactured for a Houston based engineering and construction company to complete an on-going project in South Africa. The polyurethane foam insulation is wrapped with a vapor barrier to prevent moisture, and the ends are coated with a monolar mastic paint to seal the pores. The carbon steel fabrication that surrounds the insulation has an elaborate three-coat paint system to help protect the steel from corrosion. This design allows for an integral combination of insulation and structural support in one pipe support assembly. It also minimizes labor in the field in regards to the installation of insulation.

Snubbers with Yoke Clamps for a LNG Plant

Snubbers are restraining devices. They allow free thermal movement during normal operations but restrain in abnormal circumstances such as with an earthquake. These snubbers were fabricated from carbon steel. They measure 2 1/2” x 24” and the yoke clamps have pipe sizes of 23” and 25”. Each snubber weighs 890 lb. and has a travel capacity of 24”. Designed for the support of a cryogenic line, these snubbers can handle loads of up to 2,900 lb.

4 Pig Launchers and Receivers for a Petroleum Company

These pig launchers were manufactured from carbon steel. They have a 16 major barrel, 12 minor barrel and measured 121 long. The pig launchers and receivers are used for cleaning piping systems. In addition, the pig launchers and receivers were designed for pressures of 512 PSIG at 100F. Hydro-tests were performed at 666 PSIG and x-ray tests were completed to ensure quality performance.

U-Type Constants for an Oil Refinery in Taiwan

These Figure 200 U-Type horizontal upthrust constants are designed to support piping from below. They are fabricated from carbon steel. These constants were also hot dipped galvanized and then specially painted. In addition, they are able to handle loads of up to 13,600 lbs. Each constant has a capacity of 4 total travel. They range from 55 to 62 long. Load testing and external inspections were completed to ensure the quality of these constants.

Horizontal Upthrust Constants for a Power Plant

The horizontal upthrust constants (Fig. PTP200-U) were fabricated from carbon steel and chrome-moly for a Heat Recovery Steam Generator. The constants range in sizes PTP-200 size 3 to 65 and weigh from 24 lbs to 1,300 lbs. They support loads of 100 lbs to 8,100 lbs. The constants support pipes and equipment subjected to vertical movement due to thermal expansion at locations where transfer of stress to other supports or equipment can be critical. Horizontal upthrust constants are utilized in areas where horizontal travel is unacceptable. Standard testing was completed for performance and quality assurance.

Piping Technology & Products, Inc. Performed Field Services for a Power Generating Plant in Texas

PT&P was contracted to assist in the determination of pipe support maintenance at a power plant in Texas. The constant effort support springs with loads of excess of 9,500 lbs and the variable spring supports with loads of 450 lbs were marked for needing attention.

Cleaning Variable Spring Unit

Inspecting Variable Springs for Performance

PT&P's objectives were to:

* Evaluate the pipe supports
* Determine state of performance
* Provide a plan of action
* Train personnel on-site to perform adjustments and replacement of supports or support components
* Provide final inspection of modified supports

After Cleaning & Preparation of the Constant

Final Assembly with Added Slide Plates

The pipe supports needing attention could not be set to the required installation position. A plan was initiated to recondition some of the support components such as turnbuckles and rods. This would allow a greater range of field adjustment to the pipe supports. During a planned shut-down, PT&P Field Service Units returned to the site to modify the existing supports. The initial phase of the modifications included bracing the piping in order to isolate and lock the supports in position. Then, they were disconnected from the system and modifications to the assemblies were completed. Afterwards, the supports were reinstalled and any necessary adjustments were completed. A total of eight pipe supports were modified or adjusted.
