1. Scope of Application
XDHM-series wrapping machine is designed for wrapping the buried pipe with cold applied tape.
It suitable for 400 mm -700 mm diameter pipe.
2. Structure Introduction and Function Principle
1) Frame: The main structure for bearing the body machine
2) Roller: Adjusting the balance of the cold applied tape. Combination with the roller releaser to
realizing non wrinkle ,non bubble of the cold applied tape.
3) Adjusting the wrapping tension of the cold applied. The roller and steerable wheel work together
can keep the tape balance ,adjusting the elongation of the tape.(Tension adjuster can change the
tension of the tape)
4) Steerable wheel: Stable the frame, adjusting the tape lapping width, compressing the wrapped
tape by the wrapping tape, to increase the adhesion of the tape and the pipe ,and without bubble.
3. Installation and Operation
Clean the pipe , brush the primer ,then wrapping the tape.
1) Installation: Open the trigger pin to separate wrapping machine from the trigger pin side,
install the machine on the pipe, then close the trigger pin.
Installing the wrapping tape on the roller releaser then adjusting the required tension.
Adjusting the roller and steerable wheel , lapping the tape with required lap width.
a) Installing the tape on the release roller 3, adjusting tension adjuster until the elongation meet the requirements.
b) Adjusting angle between the steerable wheel4 and the pipe until the tape lapping width meet the requirements.
(Note: Lapping width adjusting : Preliminary adjusting: Adjusting three pair of steerable
wheel to the same angle, rolling the machine to make the step distance same as the
lapping width . Fine adjusting: Installing the tape fine adjusting the required lapping width.
c) Adjusting the roller and release roller, making it reach the balance tension between
the tape and the release roller 3, and the tape without wrinkle ,straight.
d) Adjusting the steerable wheel3,roller 2 and release roller 3, to realize non wrinkle ,non bubble of the tape and the lapping width that required.
Besides, we also produce the wrapping tape and primer
