connections, and all other dead ends at a traced object shall be traced to its extremity or up
to and including its first shut-off valve.
7.4 Thermal expansion
- The thermal expansion for tracing will be define by EPCC CONTRACTORS following
tracer material final choice:
Type of steam Material Thermal Expansion
LP Steam at 185 C Stainless steel pipe To be defined during EPCC
stage
MP Steam at 290 C Stainless steel pipe To be defined during EPCC
stage
- On long runs, tracers shall be provided with expansion loops. The loops shall be extended
outside the insulation and shall be insulated separately.
- Installing flange connections in loops is not allowed.
7.5 Instruments
Tracing of instruments shall be as per the Project Specification - Installation of on-line instruments
- RAPID-FE1-TPX-INC-DES-0001-9018 and as per Instrument Hook-up.
7.6 Supporting
- Tracer feed and return lines (lines running from manifold to tracer or from tracer to
manifold) shall be adequately supported with an acceptable method, preferably from, but
not attached to, adjacent structural steel and not from process lines.
- The distance between support points shall not exceed 3 m. Supply and return lines, coming
from or going to the same manifold, shall be grouped together as much as possible for
common supports.
- Tracer supply and return lines shall not be pocketed except where absolutely necessary for
head room, operation and maintenance.
