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.
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.
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.

This photograph shows a number of 60” pipe shoes fabricated by Piping Technology & Products, Inc. of Houston, TX for export to Saudi Arabia. The Saudi Arabian Oil Company is purchasing a variety of sizes of this type of shoe and other items required for piping on their projects. Piping Technology furnishes all types of pipe supports including PTFE, 25% glass filled, and graphite slide plates, anchors and insulated pipe shoes.
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 operators 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.
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.

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.
The photograph above shows construction site of a new petro-chemical facility near Houston, Texas. Pipe supports supplied by Piping Technology & Products, Inc., including variable spring supports, are shown in the foreground. Piping Technology & Products, Inc. fabricates expansion joints, hot and cold shoes and other items to specification for the piping industry.
Piping Technologies & Products, Inc. has a highly qualified engineering staff to meet the most critical requirements of the industry.
The two pictures above show a variety of spring supports for piping projects. At the top left is a row of spring hanger variables ready to form assemblies with rods, clamps and other hardware. Piping Technology & Products, Inc. manufactures all types of pipe supports and provides complete assemblies packaged and tagged to customer specifications for easy identification by the field crews who install them in power plants, petrochemical plants and paper mills. On the pallet at the top right and scattered through the lower picture are several Type F (base type) variable supports. Special features such as travel stops and the wide range of load and travel requirements result in a large variety of items built to satisfy particular customer requirements.
Large fabricated pipe support being welded by one of Piping Technology’s welders. When it is completed it will be shipped to a major refinery in the Virgin Islands.

Pictured above are special Type F variable springs being prepared for shipment overseas. Finite element analysis was used to specify stronger load columns to allow for a possible 30% lateral load. Loads as high as 30,000 pounds were required for some items. These variables also required a special three coat paint (white).
Engineered spring hangers shown are being calibrated and tested at Piping Technology & Products, Inc., Houston, Texas Facility. A digital load cell is attached to the hydraulic press that guarantees calibration to the exact loads specified. The spring hanger will support the tubes in a reformer furnace destined for Venezuela.
The picture above shows a 20 foot section of a “Finger Joint” expansion assembly produced by PT&P for the Howard Franklin Bridge from Tampa to St. Petersburg in Florida.
This section is assembled and ready for shipment. Note the galvanized finish on everything except the temporary shipping bars. Each assembly includes four sections having a total weight of 11,227 lb. The fingers on this bridge are tapered to minimize tire damage to vehicles.
The pictures above show cryogenic pipe supports designed by a Houston E&C firm for a LNG plant in Algeria. Piping Technology & Products, Inc. fabricated the these supports for a 14” pipe which operates below –50oF. Three different materials are used. The upper part which bolts to the pipe is fabricated from an alloy which retains its strength at low temperatures. The middle section is a Permali® block selected because of its strength and durability and because it is a poor conductor of heat. The bottom plate of galvanized carbon steel is bolted to the Permali® block. Permali® is a phenolic laminate made from layers of wood impregnated under vacuum with a synthetic resin. A crossed orientation of the hard wood fibers is used to provide extra strength.

The photograph above shows a unique combination of Type F variable springs designed by a client engineer to support large skid-mounted pumps. Piping Technology & Products, Inc. fabricated the connecting assemblies which use variable springs inside pods to support the pump skids from the side. The number of pods varies from size to twelve, depending on the size of the pump, and the loads supported by each type F spring vary from 1800 to 3400 pounds depending on the geometry of the assembly. The distance between rods varies from two to three feet. A total of nine units are being exported to refinery project overseas.

The vertical constant is used when piping stress is critical and pipe is subject to vertical movement in excess of ½ inch due to thermal expansion, and also at locations here it is necessary to avid any transfer of stress from support or onto critical terminals or connecting equipment. These constants are manufactured by Piping Technology & Products, Inc.
In construction of the horizontal constant, Piping Technology & Products, Inc. uses high quality materials and workmanship throughout, with a liberal factor of safety to insure against temporary shock and overload. Springs hot-wound, double heat treated, pre-set and pre-tested.
Piping Technology & Products, Inc. supplied both “hot shoes” for high temperature lines and “cold shoes” for cryogenic lines in this new plant. The shoes sit on the steel beams of the pipe rack and support the insulated pipe. The bottom photograph shows several of the shoes prior to shipment. The two large cold shoes in the foreground are lined with PUF (polyurethane foam) which functions both as an insulator and as a load bearing member at temperatures as low as –300oF. Hot shoes are lined with calcium silicate or Marinite® which can function up to 1200oF.
