Description
Replacement StoneAge Cable Swivel Tool CST Nozzle For Furnace & Boiler Cleaning

Introduction

The patented, hollow-shaft CST-AIR slides on a 3/8 in. (9.5 mm) diameter stretched cable (not supplied) and is moved by a separate pulling cable. Head rotation is powered by an air motor. Extension nipples further adapt the tool to various vessel sizes and improve jet quality by reducing stand-off distance. The Cable Swivel Tool is an air powered swivel designed for large vessel and boiler cleaning. The powerful rotating jets cover a large area for efficient cleaning. An air motor and gearbox rotate the head of the tool. The CST has a hole through the center, through which a cable is passed. Up to 3/8"Ø cable may be used.

The cable is strung across the vessel, and the CST is pulled along the cable by jet reaction force or by another cable attached to the pulling eye or high pressure hoses. The tool can be used at operating pressures up to 10000 psi and flow rates up to 150 gpm. It has two 1" NPT female inlets in the body. One of these ports may be plugged. The tool has a flow rating of Cv=5.3. At 150 gpm, the pressure drop through the tool will be 800 psi. The standard nozzle head has six 3/4 NPT female ports; two opposite at 90°, two opposite at 80°, and one at 70° matched with one at 110°. Two or more may be plugged; always use balanced combinations of ports.

The CST should be greased at the three zerks every 40 hours to protect the bearings. The bearings are factory sealed, and should be replaced when they lock up.
Always check the pulling eye for free rotation before use, otherwise the pulling cable will get wrapped around the support cable.
The air motor lubricator should be refilled every 12 hours.
When ready to begin using the tool, start the rotation before going up in pressure.
We recommend hanging the high pressure hoses from slings at intervals along the cable.


Safety Warning

Operations with this tool can be potentially dangerous if caution is not exercised prior to and during tool use. Please read and follow all of these instructions.
2.1 Only competent and trained persons should operate this equipment.
2.2 Do not exceed the maximum operating pressure specified for any component in a system.
2.3 This equipment should always be used with an operator controlled dump mechanism to release the high pressure water.
2.4 The immediate work area should be marked off to keep out untrained persons.
2.5 All personnel in the area should wear eye protection, and other protective clothing in accordance with specific conditions.
2.6 The tool should be securely supported. Strong thrust is created by waterjets and these forces can become unbalanced if a nozzle should become plugged.
2.7 Inspect the equipment for visible signs of deterioration, damage, or improper assembly. Do not operate until repaired. Make sure all threaded connections are tight and leak free.
2.8 Check to see that all control functions work properly before going to high pressure.
2.9 If it is necessary to have a person work near the cleaning jets, then it is this person who should have control of the pressure dump mechanism.
