7.0 TENSIONING AND DE-TENSIONING
Never stand in-line with the bolt
axis while the system is pressurized. If the bolt
should fail, serious personal injury or death
could result if loose or broken parts become
projectiles. All personnel must be aware of this
potential hazard at all times.
Ensure that the maximum
working pressure and maximum stroke are not
exceeded. Refer to the specifications stamped
on the tensioner body. Also see Table 2 at the
end of this document.
IMPORTANT: If the maximum stroke indicator
appears at any time during the following
procedures, immediately STOP the pump,
tighten nut(s) at the tensioner(s) and release
hydraulic pressure. Then, turn down the
threaded puller(s) to return the piston(s) back
into the tensioner(s) before continuing. Refer to
Section 4.1 for additional information.
IMPORTANT: If any leaks occur, immediately
stop the pump and open the pressure release
(return-to-tank) valve. Be sure that the oil
pressure gauge indicates zero (0) psi/bar. Make
repairs as required before continuing with
tensioning procedures.
Note: For improved illustration clarity, only
one hydraulic hose is shown connected to the
tensioner in figures 7-11.
7.1 Tensioning Instructions - 100% Coverage
(tensioner installed on each stud)
IMPORTANT: Read precautions and instructions
at beginning of Section 7.0 before beginning the
following steps. Also refer to safety information
contained in Section 2.1.
1. Ensure that the joint is correctly aligned.
2. Assemble the tensioner(s) to the stud(s)
and connect hydraulic hoses. Refer
to sections 6.1 and 6.2 for additional
tensioner installation and hose connection
instructions.
3. Determine the required hydraulic
tensioning pressure. This value must be
calculated by a qualified engineer with
bolting experience.
4. Operate the pump and pressurize the
tensioners up to approximately 1000 psi
[70 bar]. Check for oil leaks.
