Structural Supports with Megalug Pipe Attachments
Piping Technology & Products, Inc. Designed and Fabricated Structural Pipe Hangers with Megalug® Pipe Attachments.
These are carbon steel structural supports designed for 6″, 10″ and 12″ ductile iron pipe. They are hot dip galvanized to protect against corrosion and will be used in conjunction with hydraulic snubbers. The hydraulic snubbers are used to protect against axial shock loading, as well as providing vertical weight support.
Each support utilizes a Megalug pipe attachment to eliminate the need for field welding. The Megalug® attachments are designed to “bite” into the sides of the pipe providing an attachment point for the flanges on the fabricated clamp.
The 6″ supports are designed for a maximum vertical load of 3,770 pounds, while the 10″ and 12″ supports are designed for a maximum vertical load of 11,630 pounds. All of the supports are built for an overall height of 55-1/8″ from the upper support steel to pipe centerline.

Cold Shoes to be Shipped to Puerto Rico
Normal pipeline insulation is not designed to support the pipe or its contents. When insulated pipes are supported, the weight of the pipe, the contents, the operating temperature, and the amount of energy loss must be considered. In order to support the pipe and minimize energy loss from heat transfer, a pre-insulated pipe support is necessary. If the material in the pipe is high temperature such as high pressure steam or heating oil, then high temperature insulation is required, and these supports are called hot shoes. If the material is cold, such as liquefied natural gas, cooling water or ammonia, then low temperature insulation is needed, and these types of supports are called cold shoes.
PT&P received the order to fabricate 140 cold shoes from a contractor in Puerto Rico. The overall weight of the order was 11,000 lbs and was produced in 8 weeks. The shoes were designed to support 8, 10 and 12 inch pipe sizes with 2 inches of insulation. They were designed using our Pipe Shields Division and correspond to the following model numbers: B2000, B4000,and C4100. These can be seen on our Pipe Shields website or you can request a catalog.

Big Ton Springs used in a Chemical Processing Plant
The limiting constraint in designing and fabricating these big ton spring supports was to maintain an overall height less than 15-3/4″ and still allow the load table to travel downward during operation. Whereas a standard PT&P size 2-190 variable springs would have been sufficient to hold the load specified, the coil alone was taller than the space available at site. For this reason, a “big ton” design was implemented which utilized six smaller coils (2-130 size) working in parallel to produce the required load-carrying capability and spring rate.
All of the frame/housing components were made from carbon steel and supplied with an HDG finish. The travel stop rods were made of A-193 Gr. B7 material and were painted red. The slide plates sitting atop the load flange were made of polished A-304 stainless steel.
Both “big ton” assemblies are 30″ wide by 30″ deep by 15-3/4″ tall. Overall spring rate is 3,600 lb/in. and each weighed approximately 1,460 pounds. The installed (cold) load = 14,800 lbs. and the operating (hot) load = 16,075 lbs. Movement from cold to hot = 0.354″ down.
Tested in the load cell to insure proper operation throughout the entire working range of the coils, the “big tons” were then set to the cold (installed) load as specified.

Variable Springs for a Project in Mexico
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.
