Instruction of use

V

Before operation make sure of the following:

  • Skill and knowledge are required to obtain a good quality joint.
  • The machine should be placed on a stable and dry plane to operate.
  • Check field generator for adequate power supply and fuel sufficient to complete the fusion joint.
  • Make sure the blades of the trimmer are sharp and the Teflon in the heating plate is in good condition.
  • Ensure you select the proper temperature according to the pipe manufacturer’s recommendation.
  • pyrometer or other surface temperature measuring device should be used periodically to ensure proper surface temperature of the heating tool plate.
  • Place the appropriate inserts for the pipe OD or the fitting being fused.
  • Pouring water or applying wet cloths to the joint to reduce cooling time is not acceptable.

Non-stick coating
Coated surfaces have been treated to reduce polymer adhesion. If the polymer adheres to the heating plate, lightly wipe with a clean cotton cloth to remove. Do not use a wire brush or an abrasive.

Welding parameters
Pipe manufacturers have established qualified fusion procedures which should be followed precisely. You should obtain a copy of the pipe manufacturer’s procedures or appropriate joining standard for the pipe being fused.

Heater temperature
To meet pipe manufacture’s temperature specifications, the surface temperature of the heating plate should be measured with a surface pyrometer prior to initial use and at reasonable time intervals thereafter.

Welding procedure

Description of Method
The principle of Butt fusion is to heat two surfaces to a designated temperature, then fuse them together by application of a sufficient force. This force causes the melted materials to flow and mix, thereby resulting in fusion.

The butt fusion procedure has 4 stages:

  • Stage #1: Pipe Preparation
    • Cut and Clean
    • Trim
    • Align
  • Stage #2: Heating cycle
    • Preheat
    • Heating up
  • Stage #3: Welding
    • Welding time
    • Cooling time
  • Stage #4: Removing Pipe
    • Inspecting

Pipe Preparation

Cut and Clean Trimming pipes Alignment



| ****


| ****


Cut the pipe and clean the inside and outside of both ends of the pipes with a clean lint- free dry cloth. Remove all dirt from the clamps surfaces where the pipes will be clamped in the butt fusion

machine.

| Face the pipe ends until the trimmer bottoms out on the stops and is locked between the clamps to establish clean, parallel mating surfaces between the pipe ends. Open the clamps, remove the trimmer and clean the inside and outside of both ends of the pipes with a clean

lint-free dry cloth.

| Check the pipe ends for high low alignment and out- of-roundness. If adjustment is needed, adjust the high side down by tightening the high side clamp. Do

not loosen the low side clamp or slippage may occur during fusion. Re-face the pipe ends if excessive adjustment is required and remove any dirt with a clean, lint-free cotton cloth. The maximum OD high- low misalignment allowed in the butt fusion procedure must be less than 10% of the pipe

minimum wall thickness.

Heating cycle

  • Preheat: Verify that the heater surface temperatures are in the specified temperature range according to the standard. Please follow pipe manufacturer’s procedure. A pyrometer or other surface temperature measuring device should be used before the first joint of the day and periodically throughout the day to insure proper temperature of the heating tool plate.
    The thermometer on the electric box indicates internal temperature of the heater which varies from the actual surface temperature.

  • Place the Heater: Place the heating tool in the butt fusion machine between the pipe ends. The heater must be clean and must have its Teflon coating in good condition

NOTICE : Incorrect heating temperature can result in questionable fusion joints.

Welding

Bring the pipe ends into full contact with the heating tool at fusion force.
After the heating cycle is completed and a slight melt is observed around the circumference of the pipe, maintain contact without force, while a bead develops between the heater and the pipe.
Remove the heater and quickly apply fusion force with the lever handle in accordance with the pipe manufacturer’s recommended fusion procedure or appropriate joining standard. The quicker you can safely do this process, the better.
A torque wrench can be used when a specified Interfacial Pressure is required. Hold this force for at least 10 seconds. After 10 seconds, the locking cams will assist by maintaining jaw position during the cooling cycle.
An interfacial pressure of 60 to 90 psi (0.41 to 0.62 Pa) is used to determine the force required to butt fuse the pipe components. Multiply the interfacial pressure times the pipe area to calculate the fusion force required (lb). For manually operated fusion machines, enough force should be applied to roll the bead back to the pipe surface. A torque wrench may be used to apply the proper force. Manual fusion without a torque wrench has been used successfully by many gas utilities.
NOTICE : Failure to follow pipe manufacturer’s heating time, pressure and cooling time may result in a bad joint

Removing Pipe
After pipe has cooled sufficiently, apply closing force on the lever handle and push the locking cams down into the unlocked position. Unscrew the clamp knobs enough that they can be swiveled outward. Inspecting: Visually check the entire joint. The joint should be smooth symmetry, and the bottom of groove between the beads should not be lower than the pipe surface. The misalignment of two beads should not exceed 10% of the wall thickness.

Reference Welding Standard
According to the ASTM F 2620

Pipe and fitting manufacturers have established qualified fusion procedure which should be followed precisely. You should obtain a copy of the pipe manufacturer’s fusion procedures or appropriate joining standard for the pipe being fused. Follow the procedure carefully and adhere to all specified parameters
