III. Learning of pipe grooving machine

A pipe grooving machine is a specialized tool used for creating grooves or grooved ends on pipes. These grooves allow for the installation of mechanical pipe couplings, which are commonly used in various industries for joining pipes together.


The process of pipe grooving involves cutting or forming grooves on the pipe's outer surface. This is typically done using a pipe grooving machine, which can be manual, hydraulic, or electrically powered.

Here's a general overview of how a pipe grooving machine works:

Preparation: The pipe to be grooved is measured and marked to indicate the desired groove location.

Setup: The pipe is secured in the grooving machine using clamps or other holding mechanisms. The machine's settings, such as groove depth and width, are adjusted according to the specifications of the coupling to be used.

Grooving: The machine's cutting or forming mechanism is activated, and it moves along the length of the pipe, creating the groove. The specific method of grooving depends on the type of machine being used.

1. Roll Grooving: In roll grooving, the machine uses grooving rolls that gradually press into the pipe's surface, forming the groove as the pipe rotates.

2. Cut Grooving: In cut grooving, the machine uses a cutting wheel or blade that removes material from the pipe, creating the groove.

Inspection: After grooving, the pipe is inspected to ensure that the groove meets the required specifications, such as depth and width, as specified by the coupling manufacturer.


Pipe grooving machines are commonly used in industries such as fire protection, HVAC (heating, ventilation, and air conditioning), plumbing, and industrial piping systems. They offer a fast, efficient, and reliable method for creating grooves on pipes, enabling quick and secure pipe connections using mechanical couplings.


It's worth noting that specific pipe grooving machines may have additional features and variations in their operation, depending on the manufacturer and model. Therefore, it's always important to refer to the machine's user manual and follow the manufacturer's instructions for safe and accurate operation.


IV. Points for Attention

1. During use, ensure reliable grounding and anti-creeping machine.

2. During use, loosen the air bleed screw of oil pump.

3. Strictly prohibit kids from touching the machine, in order to prevent accidents.

4. Prohibit sharing socket with large-power electrical machine, such as electric welding machine.

5. To add hydraulic oil, please use 20# hydraulic oil in summer and 10# hydraulic oil in winter.

6. During work, after pinch roller touches the pipe, please feed slowly; sway the hydraulic feed handle once after the machine rotates for more than one circle.

7. When the machine is stopped from use, please restore the pinch roller to max. clearance status, lock the pressure relief valve switch and tighten the air bleed screw of oil pump.

8. In case of pipe deviation during work, please adjust height of the bracket.


V. Transmission System

With crosshead shoe coupling, gear motor brings along principal axis to rotate, so as to further reduce mechanical power loss. Feeding action is completed with manual hydraulic system.


VI. Electrical System

Electrical system of this machine consists of one motor, one switch and connecting cable. The switch controls start and stop; the load is only one motor. Power supply shall meet motor requirements. Before start, ensure safe grounding.


VII. Operation and Adjustment

1. After start and during idling, inspect the operation of this machine.

2. Put one end of the pipe, which needs channeling, onto roller of this machine, and put the other end onto the bracket. The bracket shall be located at 3/4 of total length of the pipe. Adjust bracket height, so both ends of the pipe remain horizontal, or the bracket end is slightly lower for 1—2 degrees. Start the machine, and observe whether the pipe deviates. If the pipe deviates, adjust left and right position of the bracket, until the pipe doesn’t deviate.

3. To start working, lock pressure relief valve switch of oil pump, loosen air bleed screw of oil pump, and sway the handle of oil pump, so pinch roller touches the pipe. Start the machine, so pinch roller presses the pipe gradually. At the beginning, sway the handle of oil pump quickly, so as to form the original indentation. Then, sway the handle after the pipe is rotated for more than one circle.

4. Channel depth adjustment and limit: loosen the stop nut, and measure indentation depth of the first pipe. If it meets requirements, lock the stop nut, channel every pipe until more force is required to use the handle. Stop swaying the handle, wait for the machine to rotate for several circles, and loosen pressure relief valve switch. As a result, the pinch roller is reset automatically. At the time, turn off electricity and take down the pipe.


VIII. Maintenance and Care

1. Before start, inspect whether every moving part and the machine are normal, air bleed screw of oil pump is loosened, electrical part is intact and hydraulic oil is sufficient. On completion of work, wipe the working surface, apply anti-rust oil, add engine oil to movement junction, and lock pressure relief valve and air bleed screw of oil pump.

2. Add correct grade of hydraulic oil according to the user’s manual. Before adding, wipe dust from the hole orifice.


IX. Troubleshooting


Fault Phenomena Fault Analysis Troubleshooting
Voltage buildup fails 1. Pressure relief valve switch is not tightened. Tighten pressure relief valve switch
2. Check valve inside the valve body cannot be closed Dismantle and repair the check valve
Lack in oil Add hydraulic oil
It doesn’t work when swaying plunger rod of oil pump 1. Insufficient oil Add hydraulic oil
2. Too dirty oil blocks the oil suction hole Wash oil line and replace hydraulic oil
3. Fitting surface of oil suction valve leaks Remove the small oil cylinder; use a tool to knock the steel ball of oil suction valve
4. Oil seal of small piston is damaged Replace the oil seal.
Principal axis of oil pump leaks oil Oil seal of principal axis of oil pump is worn or burred Replace oil seal of principal axis
Pipe deviates seriously 1. Bracket height and direction are improper Adjust the bracket
2. The lower knurl wheel is worn Replace it
3. Pinch roller bearing is damaged Replace it
Oil suction is not smooth 1. Oil line is blocked Remove sundries from oil line
2. Large vacuum degree Discharge air
3. Excessive viscosity of hydraulic oil Replace hydraulic oil
