Inside of the Pipe Anchor

Piping Technology & Products, Inc. manufactured cryogenic pipe anchors for gas refinery in Savannah, Georgia. The pipe anchors were fabricated with stainless steel and insulated with polyurethane foam. In order to prevent cold pumping, better known as temperature driven moisture penetration, polyurethane foam was poured around a stainless steel reinforcing pad. The ten cryogenic pipe anchors were fabricated to support 4-inch, 8-inch and 12-inch pipes. PT&P’s pre-insulated pipe supports department is devoted to the production of pipe insulation productions for both hot and cold applications.

68" In Height Vertical Upthrust Constants
68" In Height Vertical Upthrust Constants

Piping Technology & Products, Inc. designed and built two, 68″ in height 100 U-Type constants for a power plant in Mexico. The vertical upthrust constants were designed to support 48,500 lb. each with a total upward travel of 3″. In order to prevent buckling of the constant housing, each constant was designed with five C7 x 14 3/4 lb. channels and a base plate of 26 3/8″ x 33 1/4″. These unique 100 U-Type upthrust constants were custom designed by PT&P to accommodate limited horizontal space requirement. The constants will be placed opposite to each other on a beam capable of supporting 99,000 lb. load of the pipe, plus the weight of the constants.

108" I.D. x 144" T-T Vessel

Sweco Fab, Inc., the ASME code fabrication shop for Piping Technology & Products, Inc., specially designed and fabricated a 108″ I.D. x 144″ T-T vessel for the Texas A&M University. The “Aggie Vessel” will be used for special research project at the university. A 24″ T-bolt closure was used for access to the vessel and two stiffner rings were installed to withstand vacuum application. Unique internal design was also applied to facilitate special equipment installation. Helium leak test at 1×10-6 cc/sec will be performed to detect leakage.

60,000 Lb. Load Type "B" Variable Spring Hangers
60,000 Lb. Load Type "B" Variable Spring Hangers

PT&P specially designed two Type “B” variable spring hangers (2-250-B) for an oil company in Ryazan, Russia. These variable spring hangers were custom designed to support a load of 60,000 lbs. with a spring rate of 3,648 lbs./in. respectively. Due to loading requirements, these variable spring hangers were also designed to accommodate a travel of 1″, upward movement.

PT&P Verifies New Designs for LNG Phenolic Base Support with Load Testing

Load Testing
Load Testing

Piping Technology & Products, Inc. performs thorough product testing to verify new designs to a LNG Laminated Phenolic base support for an E&C company located in Houston, Texas. In order to determine the failure loads for a 30″ diameter, pre-insulated shoes and a 6″ diameter Laminated Phenolic base support respectively, PT&P performed lateral-load and axial load tests. The load tests performed ensure the pre-insulated pipe shoes can safely sustain the specified design load. The insulated shoes tested for the E&C company will be in service in 2001 at Atlantic LNG, where they will be used to support the liquid nitrogen gas (LNG) lines.

Big Ton Springs Installation Guide
Big Ton 1. Measure the existing installed load setting height to make sure that the big ton spring will fit tightly into the space provided. Shim from below as needed to ensure proper fit.
2. Place the big ton spring in the designated location, making sure that all required slide plates, shims, or auxiliary steel are in their proper positions.
3. Travel stop bolts can be released after all testing has been done. The travel stops are painted red and located on each end of the big ton spring. Follow the steps below to release the travel bolt stops. Please refer to the drawings to the left.
(a) Turn the nut on travel stop bolt No. 1 one-half turn; repeat on bolts 2 through 4.
(b) Repeat in this sequential order until the load is released. The load has now been transferred to whatever the big ton spring is supporting.
4. CAUTION: Be sure that the nuts on the travel stop bolts are backed off enough to accommodate the appropriate travel (Example: 1 inch of travel – the nuts should be backed off by 2 inches from the bottom of the travel stop plate.)
5. At this time the Lifting Eye Bolts may be removed.

Tension Systems
In some cases, a straight line system of axial bellows anchors and guides is not practical or desired; or there is no reasonable way/ place to anchor the bellows thrust loads. In such cases self restrained bellows assemblies may be used, such as the double hinge restrained bellows shown below. Thermal expansion (or contraction) in the long pipe is absorbed by an offset deflection of the double hinge assembly. Bellows thrust load is carried by hinge bars, gimbals, tie rods or other such devices; hence normal tension is maintained in the pipe system and main anchors and full lateral restraint guides are unnecessary.

Big-Ton D and Big-Ton T Upthrust Constants
Big-Ton D and Big-Ton T Upthrust Constants

PT&P custom designed and built four Big Ton D Upthrust Constants(figure 1) and two pairs of Big Ton T Upthrust Constants (figure 2) for a global engineering & construction company.

These upthrust constants are installed at a Petrochemical Plant in Siberia. Due to space limitation, the Big Ton D Upthrust Constants and Big Ton T Upthrust Constants were designed for a total travel of 5″ and 4″ respectively. The Big Ton D Upthrust Constants were also designed for a load of 50,022 Ibs with a height of 26 inches. The Big Ton T Upthrust Constants with a height of 16.5″ were designed for 75,000 Ibs, and 67,464 Ibs respectively.
