Upthrust 200-U Type Constants for an Oil Refinery

The upthrust constants (PTP Fig. 200-U) were fabricated from A36 carbon steel. Weighing at 4,150 lbs each, they measure 94” long, 27” wide, and 43” tall. They support loads from 90,700 lbs to 93,000 lbs with 4” of vertical travel. In addition, they are custom designed with extra supporting points for heavier loads. They are used to support the piping system from beneath the pipeline. Upthrust constants only allow for vertical travel and are used where horizontal travel is unacceptable. Standard load and travel testing was completed to assure quality and performance.

Hydraulic Snubber Extension Rod Ends

The hydraulic snubber extension rod ends(seen above) were manufactured from carbon steel. Ranging in sizes 1 , 4, 5, and 6, the weight of each increase with size, therefore; the weight of each unit varies. Extension rod ends are used in conjunction with hydraulic snubbers to extend the overall length of an existing snubber. They are applied to piping systems when unrestrained thermal movement must be allowed but must also be restrained during impulsive or cyclic disturbance. The turn around time for these units was 3 weeks.

3 Wedge Action Mechanical Joint Pipe Supports for a Suspension Bridge

Three wedge action mechanical joint restraints made of ductile iron materials were utilized to assist in the construction of a suspension bridge. Also, these mechanical joints provide for vertical and axial restraint for the bridge. Each weighs approximately 300 lb. and measures 24” long by 16” wide, and 12” tall for a 6”, 10”, and 12” ductile iron pipe. They are capable of supporting 50,000 lb. In addition, they are designed for seismic conditions with the ability for 7” of axial travel.

Roller Stands for a Company that Manufactures "Fired Heaters"

Load Testing Rollers

Roller stands are used to support pipelines that expand and contract longitudinally in the axial direction and where vertical adjustment is not necessary. These roller stands are made of stainless steel and designed for a 26" pipe. They weigh 160 lbs and are capable of supporting 7,500 lbs. Load testing at 1,000F was completed for performance assurance.

Snubber Assemblies for a Power Plant

These assemblies are used to control a maximum shock load of 1,500 lbs within a piping system. Each Snubber was supplied with a custom designed yoke made from Chrome-Moly (A387 Gr.91), supplied with a stainless steel u-bolt and protection saddle. The travel capacity ranges from 1" to 5". An expedited delivery of two weeks was provided per customer's request.

New Patent for a High Temperature Support for Insulated Pipes
PT&P has developed a high capacity support for insulated pipes which does not rely on the insulation to carry any of the load. The design has several advantages over previous designs:

Since the insulation does not carry any mechanical load, it can be chosen solely on the basis of its thermal properties. In particular, cyclic loading, which has caused insulation failure, is not a problem.

• The support provides effective restraint for all six possible components of loads, X, Y, Z-Rotational and Translational. In particular, axial and torsional loads are readily accommodated. These represent difficulties for supports which rely on the insulation.

• It is easily installed in the field. It is attached to the pipe with a standard bolted pipe clamp. Thus there is no field welding.

The support consists of a shoe, similar to the PT&P Fig. 4500 Insulated Shoe Support for Hot Pipe (Hot Shoe) and two clamps, similar to the PT&P Fig. 50 Light Two Bolt Pipe Clamp. Each clamp is attached to the shoe by a steel plate which is designed to carry the design load, and is shape optimized to minimize heat flow from the pipe.

Three-Bolt Pipe Clamps for a Power Plant

These three-bolt clamps were designed to support operating loads from 19,000 lbs. to 25,000 lbs. These clamps were custom designed for 650F and pipe sizes from 6 to 22. They are constructed of carbon steel with weight ranging from 28 lbs. to 322 lbs.
