1. What is Stress Relieving Bracket PIPELOCK.
⚫ Conventionally supported vertical riser application(1) Installation with vinyl chloride coated vertical band
If copper pipe is directly supported with vinylchloride coated vertical band, the temperature riseof gas pipe may cause vinyl chloride coating melt.
Thermal expansion and contraction cause the loadto transfer to lowest elbow on riser causing it tobecome compressed and buckle.
(2) Installation with U bolt etc.
If copper pipe is secured by U bolt etc. suppressing
insulation, deformation and distortion of theinsulation may occur across the ages.
Thermal expansion and contraction cause the load
to transfer to lowest elbow on riser causing it tobecome compressed and buckle.
⚫

“PIPELOCK” is stress relieving bracket / clamp system forvertical riser pipes in A/C system, supporting weight of copper
pipe and reducing load on elbow at lowest floor by 50%.

2. Features⚫ Reduces gravity loading on vertical riser
Unlike a conventionally supported vertical riser installation,
PIPELOCK is brazed to the vertical copper riser and reduces
the loading created by the weight of the pipe system.
⚫

Reduces extra stress on vertical riser due to thermal
expansion by 50%
In conventional installations, the lowest elbow of
the pipe system carries the full load of the pipe
itself plus the extra stresses imposed by thermalexpansion. Installing PIPELOCK in the center ofthe vertical riser reduces the load created by thesystem components as well as the thermal
expansion by 50%.
PIPELOCK requires less space than the conventional
provision for thermal expansion and contraction atrise and fall outlet from fulcrum (flexible expansion
pipe (expansion loop, expansion offset)).

⚫

Can be applied after installation of pipe system
Because the pipe support ferrule is split, PIPELOCK
can easily be fitted onto the riser and adjusted after
the pipe system has been installed.

⚫

Temporary fixing
Tab on pipe support allows temporary fixing to facilitate brazing without slippage.

⚫

Easily adjustable
Slotted holes on wall bracket allow for precise adjustments.

RD-TKL-SPEC2-001-0* Selecting a base bracket (TKL-B, TK-K, TKL-U)
With reference to the table below, identify the distance L (the distance between the center ofcopper tube and the mounting frame), and select a base bracket.
(When the distance L (between the center of copper tube and the mounting frame) is within therange shown in the table, the mounting position can be adjusted with the elongated hole of thebase bracket)
