FIG 436A: FABRICATED TEE 

APPLICATION

Pipe Slide Assemblies are designed for the support of piping where horizontal movement resulting from expansion and contraction takes place and where a low coefficient of friction is desired.

SIZE RANGE

All sizes within maximum load rating.

MATERIAL

Carbon Steel Tee, PTFE Bonded Slide Plates and Carbon Steel Base; Plain, Painted, or Galvanized

MAX TEMP

750° F Temperature Range at PTFE: -20° F to 400° F

COMPLIANCE

ASME B31.1, Federal Specification A-A-1192A (Type 35), ANSI/MSS-SP-69 and MSS-SP-58 (Type 35).

NOTE

Maximum load as indicated is at 70° F, see Load Correction Factors under “Dimensions & Loads” tab for higher temperatures.The acceptability of galvanized coatings at temperatures above 450° F is at the discretion of the end user.
FEATURES:
  • Pre-engineered to save calculation and installation time.
  • Designed to minimize heat loss.
  • PTFE slide bearing pads.
  • Capable of supporting loads up to 2000 psi at 70° F.
  • Low coefficient of friction (see “Selection & Installation” tab) for the PTFE slide assemblies permits a smooth, unrestricted movement of the pipe and reduces overturning movements on supporting structures.
  • PTFE is chemically inert and resists attacks by chemicals, humidity, and other elements found in harsh environments provided that the steel supports are sufficiently protected.
  • Self-Lubricating, maintenance free.
  • Provides resistance to galvanic corrosion between pipe and support structure.
  • Allows for up to 3″ of insulation on Types 1, 2, 4, & 5. Up to 2-1/2″ of insulation on Types 3 & 6.
  • Allows up to 10″ of travel standard.
  • Installation option include the use of Fig 212 or Fig 432 pipe clamps (see “Selection & Installation” tab).
  • Options include: Increased travel and Tee heights, end plates, base plate with mounting holes.

    *Side load is only acceptable if appropriate end plates are added to the slide or “T” Section. **With the Fig 432 Clamp, add the material thickness. The Tees should be notched for the material thickness when welding on the Fig 212.

    LOAD CORRECTION FACTORS:

    The maximum load on the pipe slides is based on using a PTFE width of 2″ for the slide plate and a 70° F temperature. For a different temperature at the bearing surfaces, multiply the maximum load rating by the following factor.

    Fig 257 & Fig 436 Pipe Slide Assemblies Temperature vs. Load

  • SELECTION:
    1. Determine the support location based on allowable span and loading conditions.
    2. Calculate the load for each slide assembly location.
    3. Determine the lateral and axial movement of the pipe and the direction of movement, cold to hot.
    4. Select pipe slide or tee figure number and attachment configuration, welded or bolted.
    5. Select the method of slide plate attachment to support structure, welded or bolted.
    6. Designate whether guided or non-guided slide plate is required.
    7. Maximum recommended loads shown for pipe slides and structural tees are for vertical loading. Transitional loads for pipe structural tees are to be determined by customer.
    INSTALLATION:
    1. Determine offset of pipe slide-to-slide plate interface to allow maximum pipe movement in direction of greatest thermal displacement.
    2. Attach PTFE slide to pipe by welding or clamping with standard Fig 212 Pipe Clamp or Fig 432 Special Pipe Clamp (see diagram below).
    3. Attach slide plates to supporting structure by welding or bolting.
    4. Verify setting to insure full bearing between the PTFE slide and slide base surfaces under all pipe movement conditions.
