Special Vertical Type E Constant Spring Supports

Special Vertical Type E Constant Spring Supports

Piping Technology & Products, Inc. designed and manufactured special vertical type E constant spring supports for a power plant. These were designed and installed as pairs in a configuration similar to the typical G type constants. The advantage of using a pair of the special E rather than the conventional G type is that the total width is smaller as can be seen in Figure 1.

The constants were designed to support loads from 5,730 lbs to 10,690 lbs. They were fabricated from A36 Carbon steel. The dimensions of the individual constants are 60″ high, 16 1/2″ long, and 14″ in wide. The size of the supported pipe determined the width of the assembly. As with all constants built by PT&P, they were tested to verify that standard specifications for variation of load over the full range of travel were met.

24", Chrome-Moly, Three-Bolt Clamps with Stanchions

24", Chrome-Moly, Three-Bolt Clamps with Stanchions

Piping Technology & Products, Inc. designed and fabricated 24″, chrome-moly, three-bolt clamps with horizontal guide stanchions for a 765 MW natural gas-fired combined cycle facility in Mexico.

These clamps, in conjunction with variable springs, will allow for vertical and axial pipe movement while restricting lateral movements. They were made for 24″ OD pipe from 1-1/2 x 9″ stock material. Based upon design considerations, the clamp “E” dimension, from pipe centerline to outer load bolt, was 25″. The clamps were designed for operation at 1065°F and per customer-supplied information, the vertical design load was 1,848 lbs and the maximum lateral load was 19,207 lbs.

The clamp plates are made of A387 GR. 22 plate material, stanchion pieces of A335 GR.22 pipe and the side stop plates of carbon steel.

Constant Spring Hangers with Loads up to 105,000 Lbs.

Constant Spring Hangers with Loads up to 105,000 Lbs.

Piping Technology & Products, Inc., custom designed and fabricated a collection of constants for an oil refinery in New Jersey. This application required the use of suspended constants, 100-C and base constants, 200-F.

 

Constant Spring Hangers with Loads up to 105,000 Lbs.

Constant Spring Hangers with Loads up to 105,000 Lbs.

In order to support the lines at the oil refinery, PT&P designed the 100-C constant spring hangers (vertical constants suspended from beams) at two different loads and total travels. The 100-C constant with a load of 105,000-lbs. and total travel of 6″ (figure 1) is set to travel 1-3/4″ down and 1-15/16″ up. It is 38-3/8″ in width, 79-1/4″ in height and furnished with a double lug suspension to allow it to hang from a double point suspension beam.

In comparison to the aforementioned constant, this particular 100-C constant spring hanger (figure 2) has a load of 33,000 lbs. and a total travel of 4-1/2″, 3/8″ up and 1-1/2″ down. This specific constant is 24-1/4″ in width, 71″ in height and also furnished with a double lug suspension to suspend from a double point suspension beam. Although the dimensions of these two constants are similar, the size of the springs and cams are very different.

Opposed to the 100-C constant, the 200-F constant spring hanger is a horizontal constant used to support piping from below. These 200-F constant spring hangers were designed with loads of 40,750 lbs. and total travels of 4-1/2″, 3/8″ up and 1-3/4″ down. These constants will be used in conjunction with sway struts to support pipelines at the oil refinery.

Pipe Clamps

Pipe Supports on Shipping Floor

Piping Technology & Products, Inc. recently designed and fabricated 9 pipe supports with loads up to 75,000 lbs. for a 750MW power plant in Alabama. After extensive engineering hours and structure analysis, PT&P’s engineering department produced a detailed design and 3-D model for the supports that would allow them to run electronic interface checks. The supports are to support the cooling towers’ circulatory water system at the power plant. Six of the 9 supports were designed for a 60” line and 50,000 lb. load, and the remaining 3 were designed for a 78” line and 75,000 lbs. of load.

Furnace Springs Versus Standard Springs The major differences between standard springs and furnace springs are their construction and intended use. Furnace springs operate in much the same way as other variable spring supports. They are designed to support the pipe and tubes that are subject to vertical thermal movement. The design changes come about because, furnace springs are exposed to extreme temperatures.

FURNACE SPRINGS STANDARD SPRINGS
COATINGS Red oxide primer in order to aviod potential hazards when exposed to high temperatures Hot dipped galvanized which tends to melt the zinc coating. Molten zinc can damage surrounding pipe and equipment.
CONSTRUCTION
Unique to its application and intended use
Welded design for housing assembly
Centers the spring coils within the housing and accommodates lug attachments
Interchangeable
Bolted configuration for the housing
DESIGN Spring used as a means to determine the loading of the catalyst tubes
