Installation
–
Threaded Bottom:
Follow appropriate safety procedures for lifting, moving, and working around the
stuffing box and related equipment.
1.
Ensure that the stuffing box is installed right side up.
2.
Confirm that all threaded box and pin connections are clean before threading in the stuffing
box. Do not cross-thread.
The stuffing box can safely be installed over the polished rod thread protector, provided the
thread protector is not larger than the polished rod.
3.
Make threaded bottom connection as per standard company procedure.
The stuffing box should be threaded by using a pipe wrench above the threads on the
bottom section of the stuffing box.
4.
Perform visual inspection to ensure the installation was successful.
Operation
Compressing the Packing:
1.
If the stuffing box is equipped with vee or chevron packing, the cap to the mid-body connection
needs to be hand tight. The mid body to lower body connection only needs to be tight enough
to activate the chevron or vee packing.
Generally, all sections should be hand tight. A section that is too tight will cause the packing
to wear quickly and if it is too loose then it will cause the packing to leak.
2.
If the stuffing box is equipped with steam seal packing, then the sections need to be tool tight to
properly activate the packing. A 36” pipe wrench can be used to tighten until snug.
If equipped with a pivoting section, it may be necessary to hold both the sections
being tightened with tools to avoid the possibility to rotation.
3.
Ensure that the set screw in the cap and the body of the stuffing box is correctly torqued to
minimize the risk of back off during operation.
