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.

PTFE, 25% Glass Filled, Cut and Bonded to a Polyslinger
PTFE, 25% Glass Filled, Cut and Bonded to a Polyslinger

Piping Technology & Products, Inc. cut and bonded a PTFE, 25% glass filled, ring (see fig.1) to a polyslinger which will be utilized at a Chemical plant in Texas.

The polyslinger was a total weight of 33 lbs and its lip measured at 26″ O.D. The PT&P worker cut the PTFE, 25% glass filled, at 24″ I.D. with a thickness of 3/32″ and then bonded it to the lip of the polyslinger with an epoxy resin adhesive. PTFE, 25% glass filled, is used as padding, intended for reducing metal-to-metal friction.

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.
