Pipe Support Standards

Vertical load transfer; allows axial & lateral sliding

Typical use: Horizontal lines on pipe rack / sleeper

T-shoe or rectangular shoe; height suits insulation thickness.

Restrains lateral movement; allows axial movement

Typical use: Long straight runs, near expansion loops

Maintain clearance for thermal growth in axial direction.

Restrains all six DoF

Typical use: Loop midpoints, equipment isolation

Requires structural and stress verification.

Two-direction restraint (lateral + vertical up)

Typical use: Small-bore lines, uplift restraint

Avoid on hot insulated lines without saddle.

Vertical pipe weight support

Typical use: Vertical risers

Use lugs welded to pipe for hot service.

Off-elbow vertical support

Typical use: Elbows, corners with insulation

Stress check required at elbow attachment.

Supports weight while allowing thermal vertical movement

Typical use: Hot lines with vertical thermal growth

Acceptable load variation typically <25%.

Constant load through full vertical travel

Typical use: Critical hot lines, equipment nozzle relief

Use when load variation >25% or near sensitive nozzles.

Restrains dynamic/shock loads, allows thermal motion

Typical use: Seismic, water hammer, slug flow

Periodic functional testing required.

Reduces friction at sliding shoe interface

Typical use: High thermal movement, hot lines on rack

Reduces friction coefficient to ~0.10–0.15.

Primary horizontal steel carrying multiple pipes on a rack tier

Typical use: Main process pipe racks, sleepers

Structural member, not pipe hardware. Sized by structural design.

Two vertical posts + top beam carrying single pipe or small group

Typical use: Standalone runs, road crossings, rack extensions

Carries pipe support hardware (shoe, guide, U-bolt). Final size per structural design.

Vertical post (or column tie-in) with cantilever beam supporting pipe

Typical use: Single pipes off existing column/wall, tight corridors

Cantilever deflection and connection moment govern design.

Bracket fixed to wall/structure carrying pipe hardware

Typical use: Building penetrations, utility runs along walls

Verify wall capacity and anchor pull-out.

Reuse of existing structural member to carry new pipe hardware

Typical use: Brownfield, retrofit additions

Requires structural verification of spare capacity before tie-in.

Concrete or steel pedestal from grade carrying low-elevation pipe

Typical use: Sleeper alternatives, isolated runs at low elevation

Foundation design and settlement check required.
