7'- 6" Long Custom Variable Spring Hangers
These variable spring hangers were custom designed per customer specifications for a power plant in Turkey. The pipe hanger assembly measures 7′- 6″ long and the diameter of the can measures 12″. The variable spring hanger is capable of 55,137 lb. of hot load and 63,339 lb. of cold load. The assembly allows for 1″ upward travel.
In order to achieve the required spring rate, PT&P utilized a set of stacked coils (5 5/8″ O.D.) nested inside a larger coil. This produced an overall spring rate of 9,235 lb/in. The upper and lower attachments were minimized to fit within the space requirements provided.

60" Adjustable Pipe Stands for an LNG Plant
The stands were completed with a hot-dipped galvanize finish. They were also designed with a neoprene lining in the saddle to prevent metal to metal contact in the field. The function of the pipe stand is to allow for adjustment of the support after expansion or contraction of the pipeline. The simplicity of the design allows for easy installation and maintenance of the support.

Base Insulated Supports
PT&P fabricated base insulated supports used to minimize thermal conductivity between the base and un-insulated lines. The support is designed with a carbon steel bottom and a stainless steel upper for cryogenic temperatures of -300°F. The insulation is made of 20 PCF polyurethane block. These supports are designed to handle lateral and axial pipe loads. They also include a wear pad for extra pipe reinforcement, which prevents local deformation of the pipe.

26" Hot Water Expansion Tank for a Compressor Station
This sway strut is fabricated from carbon steel and measures 240″ from pin to pin. The pipe is 6″ in diameter and has a load capability of 15,000 lbs. The components were completed with a hot-dipped galvanize finish and the pipe was coated with a shop primer. The function of a sway strut is to restrain movement of piping in one direction while providing for movement due to thermal expansion or contraction in another direction.
This particular sway strut will support a 30″ process line in a refinery. This type of support is necessary, because the current line has only a few I-beams for support. Additionally, the I-beams that support the line are very high off the ground and not capable of handling the large forces acting on the line. Due to the loads acting upon the pipe and length of the required strut, a heavy schedule pipe and heavier duty strut ends were necessary.

43" Angulating Constants for a Power Plant
The design of this constant requires that it be connected by pins from the top and from the bottom to allow it to angulate. The constant assemblies are fabricated from A36 carbon steel. The constants measure between 23″ and 43″ in length with a take-off between 29″ and 55″. The load range is 60 lb. to 2,605 lb. and each constant assembly underwent standard load and travel testing.

Spider Guides for a Heat Recovery Steam Generation Plant
Components of these Cylinder Pipe Guides (a.k.a. Spider Guides) include carbon steel plates, stock clamps, angles, and hot-dipped galvanized pipes. The Guides range in pipe size from 6″ to 16″. The maximum design temperature for the Spider Guides is 750ºF.
They are designed to control lateral pipe movement and maintain the alignment of the piping through its axial and contraction cycles. A single piping run uses multiple Spider Guides to avoid a fulcrum or an imposed lateral deflection on critical components.

97" Diameter, 3-Piece Pipe Clamps for a Refinery in Ponca City
Piping Technology & Products, Inc. fabricated 3-piece pipe clamps used to support 97″ diameter stainless steel duct work. This duct work is being added to a refinery for an expansion project in Ponca City, Oklahoma. Each section of the clamp assembly is formed from a continuous plate and gussets are added at each of the bolt locations for increased strength and rigidity. Due to the ducts having a relatively thin wall, these clamps are designed wider than necessary in an effort to reduce localized stresses on the duct work. The lower section of each clamp is formed to create a 150° cradle. This acts as a cradle by supporting the duct without inducing extra pressure, which might cause the duct wall to buckle or bend.
The upper sections are formed from 1/2″ thick by 12″ wide bar stock, whereas the lower sections are formed from 1/2″ thick by 18″ wide. All three sections are rolled to an inner radius of 48 1/2″ and the welded gusset plates are all 1/2″ thick. The upper sections are formed at 105° each, and the upper load bolt is 2″ in diameter while the six clamping bolts are 1 1/2″ in diameter.
The maximum load to be carried by these pipe clamps is 16,888 lb. Each pipe clamp will be used in conjunction with a variable spring support to accommodate movements as high as 2 1/4″.
