The two pictures above show two types of polyurethane products produced by Piping Technology & Products, Inc. for piping systems. At the top are cold shoes to support piping at cryogenic temperatures. The polyurethane cradle is bonded to steel shield which is welded to a T-bar. These cradles are produced by pumping the chemical components required into a mold which gives them the correct shape. At the bottom are supports produced by drilling and machining solid polyurethane blocks. Polyurethane provides both insulation and the strength to support pipes at cold temperatures.
The two pictures above show mechanical snubbers which are used to limit the velocity of movement of piping systems when sudden accelerations caused by earthquakes, extreme wind loads or water hammer occur. These devices are designed with a brake drum which is activated by sudden movement. During gradual movement, such as would be expected during thermal expansion, the brake is not activated. Mechanical snubbers do not depend on hydraulic principles so they do not require maintenance during normal operation. The top picture shows the pins and swivel bearings used to link these snubbers to the system it will protect. The bottom pictures shows our inventory maintained for emergency deliver.
The two pictures above show hydraulic snubbers which are used to limit the velocity of movement of piping systems when sudden accelerations caused by earthquakes, extreme wind loads or water hammer occur. These devices are designed so slow movement, such as would be expected during thermal expansion, has practically no resistance, but sudden rapid movement is resisted with a force proportional to the velocity raised to a power where the power is determined by the orifice valve and flow pattern in the design. Selection of materials and liquids used will depend on the environment where the snubber is installed. The snubber at the bottom has a ball joint attached for linkage with the system it will protect.
The photograph above shows a large number of specially designed constant spring supports being prepared for shipment to Chile. These constants are the key component of a reforming furnace, radiant tube support system designed for one of the world’s major engineering and construction firms.
Piping Technology’s engineers designed these units to fit in the limited space available inside the furnace and provided optional bolting patterns so attachment to the supporting structure could be made even if the radiant tube support system assumed a competitor’s design.
