Esa instalation procedures

Picture	Description
TOOLS REQUIRED
Specific tools are required for removal of the old packing and installation of the new packing, as well as tensioning of the fasteners. In addition, always use standard safety equipment and follow good safety practices. Acquire the following equipment prior to installation: Calibrated packing ring cutter Packing extractor and torque wrench or spanner Packing knife Flashlight Safety goggles Helmet Steel rule Inside & outside calipers Tamping tool Lubricant for fasteners Vernier dial gauge Mirror Other plant-specified equipment
CLEAN AND EXAMINE
	Loosen gland follower nuts slowly and lift follower to release any trapped pressure under packing set. Remove all old packing and thoroughly clean shaft/stem and stuffing box area following plant-specified procedures. Examine the shaft/stem for corrosion, nicks, scoring or excessive wear. Examine other components for burrs, cracks, or wear that could reduce packing life. Check stuffing box for excessive clearances and shaft/stem for eccentricity. Replace any components found defective. If in doubt, seek advice. Inspect old packing as part of failure analysis for clues to cause of premature packing failure.
MEASURE AND RECORD
	Document the shaft or stem diameter, stuffing box bore and depth, and, when using lantern rings, distance of port to bottom of stuffing box.
SELECT PACKING
	Assure packing is as specified by packing manufacturer and/or plant engineering department to match service conditions. Calculate packing cross section and number of rings needed from recorded measurements. Examine packing to be sure it is free from defects. Refer to any special installation instructions from packing manufacturer. Ensure cleanliness of equipment and packing before proceeding
PREPARE RINGS
	Braided Wind packing around properly sized mandrel, or use calibrated packing ring cutter. Cut packing cleanly, either butt (square) or skive (diagonal), per instructions from packing manufacturer or plant engineering department. Cut one ring at a time, and, using shaft or stem, check for proper sizing. Die formed/molded Assure that rings are sized precisely to shaft or stem Cut rings, when necessary for installation, according to instructions from packing manufacturer or plant engineering department.
INSTAL PACKING
	Carefully install one ring of packing at a time. Twist each ring over shaft/stem. Ensure each ring is seated fully in stuffing box prior to installing next ring. Stagger joints of subsequent rings a minimum of 90 degrees. After last ring is installed, draw gland up evenly until nuts are finger-tight. Check lantern ring, if used, for correct positioning relative to port. Make sure shaft/stem turns freely.
ADJUST PACKING(VALVES)
	Consult packing manufacturer and/or plant engineering department for guidance on torque specifications or percent of compression. Tighten gland nuts in multiple steps: Step 1 – Torque gland bolts to approximately 30% of full torque or appropriate compression percentage. Step 2 – Cycle the valve a number of times and apply full torque while valve is in closed stroke position. Step 3 – Repeat Step 2 three or four times.
RETIGHTENING AND REPLACEMENT
	Caution: Consult your packing manufacturer and/or plant engineering department for guidance and recommendations on retightening. I t is advisable to check gland adjustment after a few hours of operation. Tighten as necessary. Packing must be replaced when gland can not be adjusted further.
