Custom U-Type Constant Spring Supports with Slide Plates
PT&P fabricated 12 constant spring supports of various sizes with PTFE, 25% glass filled slide plates. The smallest constant is 38.25" length x 13" width x 28" height, and the largest is 52" length x 19" width x 28" height. The designed loads vary from 13,264 lb. to 15,962 lb. and the total travel range is 2" to 3".

Custom Constant Spring Hangers and Pipe Clamps
The constant spring hangers are manufactured from A36 carbon steel and have custom 4-bolt pipe clamps due to heavy loads. The dimensions are 40" length x 18" width x 85" height and are designed for a 1,784 lb. load with 10" of travel. The constants will be used to support radiant inlet manifolds and have a unique paint applied due to the highly corrosive condition. The entire pipe hanger assembly went through load and travel testing prior to shipping.

Big Ton Springs with a Custom 3-Coat Paint System
PT&P fabricated big ton spring supports for an expedited delivery of six weeks from conceptual design to final delivery. The big tons measure 26" long x 26" deep x 34-5/8" tall and will be used to support substantial vertical loads while simultaneously providing a base support structure. They are designed for operating loads of 36,000 lb. with a travel of .5625" down.
Due to the harsh and corrosive environment, the exposed metal surfaces were finished with a three-coat urethane paint while the threaded components were cadmium plated with a blue Fluorocarbon coating. The big tons were also salt water spray tested according to ASTM B117 standards, and load tested to verify the springs' functionality throughout the entire travel range.

F-Type Variable Springs with Slide Plates
PT&P fabricated variable springs from hot-dipped galvanized carbon steel components and a neoprene coated spring steel coil. P.T.F.E. slide plates are welded to the load flange to reduce frictional forces generated during lateral movement of the supported pipe. Internal guides are also installed to help maintain vertical alignment of all moving components throughout the anticipated thermal deflection cycle. The installed (cold) load is set to 10,413 lb. With a design travel of 0.720” up, the final operating (hot) load will be 8,974 lb. Each spring is equipped with travel stops and went through load testing prior to shipping.

Big Ton Spring Supports for a Chemical Processing Plant
A total of 18 big ton springs of various sizes were fabricated from A516 Gr. 70N carbon steel. The big tons were designed in a rectangular configuration in order to match the existing vessel saddle supports and the concrete foundation below the springs. PTFE, 25% glass filled slide plates will be welded on the load flanges to allow horizontal movement in addition to the vertical movements specified. The largest of the big ton assemblies has an operating load of 79,000 lb. with a travel of .706" down.

Special U-Type Constant Spring Supports
PT&P designed a constant load support system for a fluid tank with a load of 105,000 lb. over an area of 5' W x 20' L. To prevent twisting of the fluid container, the support system is designed to allow for “level” vertical movement. This was achieved by using a special system composed of three U-Type constant units. Each unit employs two springs working in parallel with a common large base plate and a load flange to support the entire 5' width of the container.
Special U-Type Constant Spring Supports
The constants will support loads of 39,000 lb., 36,000 lb., and 30,000 lb., with a total travel of 4" in the “upwards” direction. The spring coils were coated in neoprene, and all the other major components were hot dip galvanized to inhibit corrosion. These constants were constructed primarily from carbon steel with the use of stainless steel and PTFE, 25% glass filled slide plates.

100 Type F Vertical Constant Supports
These are constants known as 100 type F vertical constant supports. They support pipe from below by means of a sway strut. They are fabricated from A36 carbon steel and hot dipped galvanized to prevent rusting. The constant in the first picture maintains a constant load of 7,000 lb. while the constant in the second picture maintains a load of 9,000 lb. on the pipe throughout its 4” of total travel. They are 36” high with two gussets at the base plate to prevent the coil housing from collapsing under test loading and normal operation. Standard load and travel testing was performed on the constant to insure proper field operation.

This Type G variable spring was manufactured for a Petrochemical Plant in Mexico. The Type G assembly is formed by welding two standard spring assemblies to the ends of a pair of channels. This type of assembly can accommodate unusually heavy loads, and is especially convenient for avoiding interference in spaces where headroom is limited.
Each spring assembly is loaded per the client’s specification at Piping Technology and Products manufacturing facilities. A travel stop is inserted and strapped in place to maintain the load for the assembly installation. In addition to banding the travel stops, the variables for this project required chained travel stops. The base style (F-Type) variables on this project were also required to have internal guides.
At Piping Technology and Products, Inc. we use PTP-1, PTP-2, PTP-4, PTP-6 and PTP-8 to designate the five standard coil arrangements to increase the working range of travel of variable supports.
Several types of variable supports were made for this particular project. They included Type A, Type B and Type F.

B-Type Constants for a Power Plant in Kentucky
These constants were fabricated from carbon steel hardware and structure. The vertical constants are used to support pipes and other equipment. They range from 4 to 6 feet and weigh between 690 lbs to 2,850 lbs. The constants have a total travel capacity of 7 to 8 . Standard load testing was completed to ensure quality and performance.
