Purpose
Purpose
The purpose of this procedure is to establish the minimum requirements to safely operate a Tubing Cutter for cutting Stainless Steel tubing sizes from 1/4" up to 1/2".
Cutting Stainless Steel Tubing larger than 1/2" is not covered in this procedure.
Procedure
Procedure
This procedure applies to all hand held and operated Tubing Cutters designed for 1/4" thru 1/2" tubing. To insure a good tubing joint the tube must be cut off square. This can be accomplished by the proper use of a Tube Cutter.
The most common types of Tube Cutters are the Ridgid brand and the Imperial brand of cutters. Both designs have foldaway Reamers for removing the inside burrs of the tubing after being cut.
RIDGID brand Tube Cutter
Imperial brand Tube Cutter
If a Tube Cutter is utilized with stainless steel tubing, remember that a special cutting wheel, designed for use with stainless steel tubing should be employed. The use of dull or improper cutting wheels can work harden the S.S. tubing near the cut area. This CAN adversely affect the fittings sealing ability.

To cut tubing with a Tube Cutter open the Tube Cutter by rotating the handle on the end of the Tube Cutter.
Slowly turn the handle until the cutting wheel touches the tubing at the desired mark where the cut is to be made.
Once the cutting wheel is touching the tubing make sure the tubing is resting between the two rollers opposite of the cutting wheel.
Apply a small amount of pressure on the cutting wheel on the tubing by turning the handle.
Rotate the Tube Cutter around the tube until there is a small grove or cut in the tubing.
Once the cutter has made a cut around the diameter of the tube the tension on the cutter wheel will be less.
Look at the tube and make sure that the cut in the tube makes a complete circle on the tube where the cutter first started. The cutter wheel should match up to the cut in the tubing. If the cut groove looks to be making threads in the tube discontinue turning the cutter. Inspect the cutter and replace the cutting wheel or determine the cause of the cutter wheel not not cut straight.
Before any work is performed all Safety precautions must be in-place according to Flogistix policy for the unit type.

Scope
Scope
This procedure applies to all service or manufacturing employees that are required to bend stainless Steel tubing and is applicable to all Flogistix employees, contractors, and temporary employees.
Hazards
Hazards
Employees should be aware of the dangers of installing stainless tubing in application that will have high pressure applied to the tubing during operation of the equipment. Employees should be aware that stainless steel tubing that is incorrectly bent or installed incorrectly could have the possibility of the tubing failing and could release high pressure gas or oil that can be flammable and toxic. Potential for the possible hazards of gas ignition or fire, hot surfaces, hot fluids, and the potential of bodily hard. Environmental hazards from the release of used oil, production fluids that could be considered an environmental spill onto ground or soil.
