It must be measured by the operator with the pressure gauge of the hydraulic unit.t1, t2, …, t5: duration of phases 1,2, …, 5.1- Approach and Preheating Phase. Bring the edges to be welded closer with the thermal element at the pressure (P1+Pt) so that the edge reaches the dimension provided for by the standard used.2- Heating Phase. Reduce the pressure to the maximum value P2, sufficient to maintain contact of the edges of the pipe with the thermal element, for the time t2Note: The operator, by reducing the pressure, must be careful not to detach the edges from the thermal element. If this happens, the welding must be repeated.3- Phase of Extraction of the thermal element. Remove the thermal element at the maximum time t3, without damaging the edges of the two elements to be welded.4- Phase of reaching the welding pressure. Put the edges in contact, progressively increasing the pressure up to the value (P5+Pt), in time t4. Prevent the soft material from coming out of the surfaces that were approached.5- Welding Phase. Keep the edges in contact under pressure (P5+Pt ) for time t5.Do not use water or compressed air to accelerate the cooling of the fusion. If necessary, protect the weld from rain, wind or excessive solar radiation. Certifications The main features of polyethylene pipe (PE), polypropylene pipe (PP) which use in water supply & drainage, gas engineering, chemical transport and cable laying is light weight, easy to install;smooth inner wall, low pressure loss;Safe and reliable;long service life;with strong adaptability to foundation settlement or earthquake fluctuation;moreover, PE/PP pipe resist corrosion of acid base. Therefore, instead of steel, PP/PE pipe more and more favored by the majority of users, it has become an inevitable trend."Quality first, service upmost" is our motto of production and operation. We always choose to keep our promise to win good reputation. For special specifications of the welding machine, we will design & manufacture according to customer's requirement.We sincerely welcome you visit our workshop.
