27' x 16' x 21' Structural Steel Frame for an Offshore Site

Base in Fabrication Process

Structural Steel Base in Painting Phase

PT&P custom designed and fabricated a 27' x 16' x 21' structural steel frame to be placed on the sea-bed for an offshore rig. This assembly will be used as an undersea cable support frame, capable of withstanding a load of 600 Kilonewtons (68,000 lbs for each pad). It is constructed of 8 tube-steel, a 10 channel, and a steel plate. The frame will remain stationary on the sea-bed and is designed to endure heavy wave action when lowered to or raised from the sea-bed.

Finite element analysis of the lifting lug on the structure was performed to verify load conditions.  A trial fit-up of bolted sections was also conducted to ensure the structural frame will assemble easily before being placed in position.

42” Hold Down with Wedge Support

PT&P designed and fabricated a Hold Down with wedge support for a 42” pipe. The entire assembly is PTFE, 25% glass filled, bonded and will be used to control and reduce pipe vibration at an LNG plant. Both the Hold Down and wedge support are made from A36 Carbon Steel and a fabric pad which is exceptionally suited for vibration impact and declination.

950 lb. load C-type Constants

PT&P recently designed and manufactured sixteen PTP-200 C-type constants modified to fit in constricted areas near a furnace of a chemical facility.  These constants are designed to travel from 5 1/2” to 19” and are specified to carry loads ranging from 245 to 924 lbs. They were fabricated from A36 plates with 4140 pins. Due to the proximity of the pipes and other equipment, the front part of the constant frame was cut to allow the pipe to move freely. Load and travel testing was performed to ensure quality and precise performance.

2,650 lb. load C-Type Constants

Piping Technology and Products, Inc. recently fabricated 22 Carbon Steel PTP 200-C type Horizontal & PTP 100-C type Vertical Constants with sizes from 3 to 27.  The load capacity of the constants spans between 215 to 2650 lbs., with a travel ranging from 1” to 4”.  The three bolt clamps are fabricated from stainless steel material A 240 Gr. 304 for 4" to 8" dia. pipes.  The rod and turnbuckle were shortened on two of the constants in order to accommodate situations of small rod take out. Standard load and adjustment testing was performed.

Cold Shoes with a Load Capacity of 75,000 lbs

PT&P recently designed and manufactured over 1,000 Coldshoes for an LNG Plant in Egypt.  These shoes are designed to support loads up to 75,000 lbs. at an operating temperature of -350°F. They are customized to fit pipe sizes of 20”, 24”, 30”, and 36”. All Coldshoes are composed of stainless steel with a Micarta® insulator.  Micarta® is a woven glass fabric laminated with epoxy resin. It is extremely high in mechanical strength, has low moisture absorption and dissipative factors, and has superior electrical characteristics which are exhibited over a wide range of temperatures and humidities.

Cryogenic Supports with Permali Block

The above design shows cryogenic pipe supports with Permali block. Permali block is a laminated phenolic material from layers of wood impregnated under vacuum and heat with synthetic resin. These pipe shoes can be designed to restrain very high axial, lateral and vertical loads. These shoes are used for LNG pipeline sliding supports with TEF slide plates.

Two 15’-0” long Carbon Steel Sway Struts for a Cycle Unit Project

Sweco Fab recently designed and manufactured two carbon steel sway struts with 2” adjustment capabilities for a cycle unit project. The sway strut is constructed of an 8” diameter pipe, 130 ¼” long, assembled with rod ends and brackets for an overall assembly length of 15’-0”. The 2” adjustment capability is accompanied by a load capacity up to 128 KIPS. Sway struts are used to restrain movement of piping in one direction while providing movement from thermal expansion or contraction in another direction.

61" x 61" Graphite Slide Plates for a Refinery Project in India

PT&P designed and fabricated eighteen graphite slide plates for a refinery project in India. These plates are made of graphite sheets with thicknesses of 6mm and 12mm. The overall dimensions of the plates are 3/8" x 19-11/16" x 19-11/16" and 3/8" x 61" x 61". The plates will be tack welded on top of big ton spring supports in the refinery to minimize frictional effects.

20,500 lb Riser Clamps for a Power Plant

PT&P recently fabricated 22 Fig. 190 Type 3 riser clamps for suspending the vertical runs of pipe at the central power plant in Puerto Rico.  The clamps are designed for 17" and 24” pipes and have an overall length of 71" and 87” respectively. Both designs have a bar stock size of 1.75"x10" and load bolts of 2.75" diameter. Utilizing gusset plates at the clamp’s bend radius allowed for the smallest, yet sufficient clamp stock size for the specified loads. The smaller clamp has an operating capacity of 14,000 lbs while the larger operates at 20,500 lbs. Chrome-Moy 387 Grade 22 bar stock was used with A193 Grade B7 bolting to accommodate high temperature operating conditions.
