INSTALLING SPM

– ANCHOR CROSSOVER ASSEMBLY

(PRIMARY METHOD)

Generally, two Anchor Crossover assemblies are required for each
swivel group assembly (two or more swivels in line), with one
crossover assembly installed on each end.
Anchor Crossovers are installed in this configuration because
swivels and swivel assemblies are designed to provide flexibility in
a flow line. While this is necessary for simplifying installations, this
flexibility allows forces to build up in the event of a flow line failure.
By "linking" SPM
the slack in the system can be reduced.
SPM FSR main lines must always be continuous from anchor
®
point to anchor point (for example, from frac trailer to wellhead).
Any time that there is a break in the main line, such as where the
main line is shackled to the anchor crossover, a second SPM
Spine main line must continue from that point and make up the
continuous main line.
NOTE: There are two types of approved shackles used on a typical
SPM FSR. Never substitute the incorrect type of shackle for the
®
non-specified application. Individual shackles or shackles on anchor
crossovers are used to tie the spine to the shackle and not used to
go through the eye or loop of the shackle. See SHACKLE DETAIL
on page 26 for complete details.
