Type F Variable Springs With Specially Made Locking Devices

Piping Technology & Products, Inc. specially designed twelve Type-F variable spring hangers (4-160-F, 8-170-F, 8-180-F) for an oil refinery in Indiana. These variable spring hangers were custom designed to support a Hydro-Test load 4.5 to 5 times the design load, which ranged from 7,988 lb. to 13,075 lb. The spring rates of the variable spring hangers ranged from 500 lb./in. to 750 lb./in. with travels of 1.15" to 2.82", upward movement respectively. The locking devices for these springs were manufactured using basic materials (rods, hex nuts and heavy pipe wall) and a special pressure plate to accommodate the application design criteria requested by the client. The base plate designed for these F- Type cans were modified to accommodate the locking devices.

U-Type and F-Type Constant Spring Supports

F-Type Constants

Piping Technology & Products, Inc. designed, manufactured and delivered a total of 8 constants to a power plant in Mexico. The designs consisted of 4 Horizontal U-Types Upthrust (Figure 1) and 4 Vertical F-Types (Figure 2) that are to support 24-inch diameter pipes. Each consisted of different sizes. The constants are designed for loads of 2,839 lbs. to 8,963 lbs., for Total Travels ranging from 7 to 3 inches. Constants were painted CZ-11 per customer request.

40" Diameter Alloy Yoke Clamp

PT&P specially designed and manufactured a heavy duty, 40-inch diameter, alloy yoke clamp (cut from a 6" thick plate) for a Power Plant in Mississippi. The clamp was designed for a 70,000 lb load and is to support a 40" diameter, high pressure main steam line. The u-bolt was made of a 3" diameter bar. In order to prove the design of this clamp, Finite Element Analysis was used to simulate the loads and stresses that it may experience in the field. The model shows the stresses at every point by a color coding system.

Custom Pipe Support Assemblies For An Oil Refinery In Mexico

Piping Technology and Products designed and built 24 custom pipe support assemblies to meet the unusual needs of an oil refinery in Mexico. The pipe hanger assemblies each consisted of a 200 E-type constant spring support and a cradle assembly. The constants are designed for loads of 9856 lb. to 13,288 lb., and for total travels ranging from 3.5" to 5.5". Operational conditions dictated that the constant springs have settings for emergency and start-up, in additional to the standard settings of cold for shipping, and hot for normal operations.

The cradle assemblies attached to the constants are to support pipes with operational temperatures of 1070°F to 1100°F. Thus while the constants could be made of A-36 steel, the assemblies could not. The pipe saddle itself was made by splitting a section of A387-11 chrome alloy pipe. The other support components were all made of 304 stainless steel. This includes a 1-3/4" Eye Rod, two 27" I.D. U-bolts, and two 33" lengths of 3" diameter SCH. 80 pipe.

Cryogenic Pipe Anchors For A Gas Refinery

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

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 1x10-6 cc/sec will be performed to detect leakage.
