Ground source heat pump PE pipe

PE pipes for ground source heat pumps

1. Hot melt socket installation, DN20-DN63mm specifications generally use this method, the specific process is as follows.

(1) Cut the pipe according to installation needs using a pipe cutter

(2) Mark the depth of the pipe with socket insertion

(3) Heat the hot melt machine die to around 210 ℃

(4) Heat the pipes and fittings simultaneously, and then insert them into the socket (wait for a moment to release the socket after it is in place, and do not twist during the heating, inserting, and cooling processes)

(5) Natural cooling

(6) After the completion of construction and passing the pressure test acceptance, it will be put into use

2. Hot melt docking installation, generally using this method for DN110-DN1600mm specifications

(1) Place the two PE pipes that need to be installed and connected on the hot melt fixture at the same time (the fixture can replace the clamp tile according to the size of the pipe diameter to be installed. If not, use a pipe bracket to support the other end of the pipe to the same level.

(2) Use electric milling cutters to mill the end faces of the pipes separately, ensuring that the two pipes can fully match each other in contact.

(3) Raise the temperature of the electric heating plate to 210 degrees, place it in the middle of the end faces of two pipes, and operate the electric hydraulic device to make the end faces of both pipes fully contact and heat the electric heating plate at the same time

(4) Remove the heating plate and operate the hydraulic device again to fully connect the end faces of the two melted pipes and lock the hydraulic device (to prevent rebound)

(5) Do you want to maintain a certain cooling time? Release, operation is complete

(6) After the construction is completed, it must pass the pressure test and acceptance before it can be put back into use

(7) During the heating process, windproof measures should be taken for the pipes. During the cooling process, it should be gradually carried out to avoid rapid cooling

3. Electric fusion connection (applicable for DN ≤ 630mm)

(1) Fully insert the PE pipe into the PE fitting

(2) Connect the two wires of the dedicated electric melting machine to the positive and negative poles of the electric melting pipe fittings respectively

(3) Connect the power supply and heat the electric heating wire to melt the PE inside

(4) Cooling completed

(5) After the completion of construction, the pipe must pass the pressure test acceptance before it can be sealed and put into use

4. Flange connection

5. Steel plastic connection

6. Saddle type docking installation is particularly effective in solving the problem of main pipe ventilation.
