24", Chrome-Moly, Three-Bolt Clamps with Stanchions

Piping Technology & Products, Inc. designed and fabricated 24", chrome-moly, three-bolt clamps with horizontal guide stanchions for a 765 MW natural gas-fired combined cycle facility in Mexico. These clamps, in conjunction with variable springs, will allow for vertical and axial pipe movement while restricting lateral movements. They were made for 24" OD pipe from 1-1/2 x 9" stock material. Based upon design considerations, the clamp "E" dimension, from pipe centerline to outer load bolt, was 25". The clamps were designed for operation at 1065°F and per customer-supplied information, the vertical design load was 1,848 lbs and the maximum lateral load was 19,207 lbs. The clamp plates are made of A387 GR. 22 plate material, stanchion pieces of A335 GR.22 pipe and the side stop plates of carbon steel.

66" Diameter, Three-bolt Pipe Clamp

66" Diameter, Three-bolt Pipe Clamp

Piping Technology & Products, Inc. custom designed and fabricated a 66-inch diameter, three-bolt pipe clamp for a chemical company located in Deer Park, Texas.

The clamp will be used in conjunction with a PT&P Spring Hanger and a length of rod in order to support the pipeline.  After formation, the clamp's dimensions measured at 97.75 OAL and 69.5 at its widest point. By using a FEA program, the clamp was designed for an operating load of 24,000 pounds at 500° F. The materials used consisted of 1 ¾ x 10 x 128 ¼ thick A-36 Carbon steel, with three 2½ studs and nuts.

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.

86" Diameter Pipe Clamps

Specially formed and gusseted 86” diameter clamps are being strapped to their pallets for their journey to Western Canada.

PT&P designed and built these specialty clamps of 3” x 16” bar stock for a major producer of oil and gas in Alberta for an application in their process sector.
