Mechanical Snubbers

Mechanical Snubbers

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.

Hydraulic Snubbers

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.

Constants for a Radiant-tube Support System

Constants for a Radiant-tube Support System

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.

Bellmouth Reducers

The picture above shows four bellmouth reducers which have just received the final coat of a special paint. These are components of the cooling water piping system designed for large, new petrochemical complex. The bell shape is a segment of an ellipse chosen to function as a vortex breaker during high velocity flow.

Refurbished Constant Supports

Refurbished Constant Supports

The picture above shows the “before” and “after” of constant supports refurbished by Piping Technology & Products, Inc. Customers ship these units to our plant during a turn-around in a wide variety of conditions. In this case it was cheaper and faster to refurbish them than to rebuild. In either case each unit is completely tested in a load cell to assure performance and a new name plate is attached to record the load, travel and other parameters. Four of these horizontal upthrust supports can be seen above, ready for return to the customers. Power plants, petrochemical plants and paper mills are the primary users of this service.

45,000 lb. Load CAD Spring Support

The photograph above shows a CAD Spring Support to handle over 45,000 lb. Load with movement in excess of 4”. This is a PTP-8, size 22 Type F Spring Support utilizing four stacked hellcat coils with eliminates the possibility of binding or squirming, problems which baffled others attempting development of such a design. Travel stops hold the coils in compression to cold load, while hydrostatic test spots prevent the coils from “bottoming out” during line tests. The spring casing and baseplate, which eliminates the need to weld after galvanizing, are paramount to the success of this design.

Tension (Pigtail) Spring Supports

Tension (Pigtail) Spring Supports

This picture above shows tension springs being prepared to support furnace tubes in a refinery reformer. The bottom picture shows one of the five springs the customer specified have a displacement scale attached, so operator’s can observe the inches of movement when the spring is expanded. These springs were part of a package of materials prepared for shipment to an overseas site by Piping Technology & Products, Inc. of Houston, TX. Our customers use spring coils to support loads from a few pounds to 100,000 pounds so they come in many sizes.

Flue Gas Duct Damper

Flue Gas Duct Damper

The picture above shows a flue gas duct damper fabricated using Inconel for certain components by the Sweco Fab division of Piping Technology & Products, Inc. Two of these dampers were shipped to Trinidad for installation above the furnaces of an ammonia plant. They have a special refractory lining to withstand the high temperatures of the flue gases. The picture at the left show the linkage of the damper to the motor-driven control system. Each unit weighs approximately 2300 lb. and the openings are approximately 12 feet by 6 feet.

Tanks Mounted on Trucks

The picture above show the replacement of a tank mounted on a truck by the Sweco Fab division of Piping Technology & Products, Inc. In this case the customer delivered the damaged tank to our site so measurements of the mounting could be obtained. The old tank (upper left) was damaged beyond repair when a vacuum was inadvertently created inside the tank.
