Tlas'a boemo ba ho se ame ho tjheseletsa ha nozzle, bolelele bo boloketsoeng ba phofo ea epoxy qetellong ea polyethylene lera e lokela ho eketsoa ka mokhoa o nepahetseng ho thibela 3PE anti-corrosion warping e bakoang ke nako e telele ea stacking eaphala ea tšepele ho kutu e tebileng ea tšepe ea pheletso ea phala.

2. Ha liphaephe tse thibelang ho bola li phuthetsoe sebakeng se bulehileng ka nako e telele, li lokela ho koaheloa lintlheng tsa liphaephe ho thibela metsi a pula hore a se ke a senya le ho baka tšenyo e tebileng ea liphaephe.

3. Haeba nako ea kaho ea lipeipi e le telele, pente e thibelang mafome e chesehang e ka penta holim'a tšepe e se nang letho ea pheletsong ea liphaephe ho thibela lera la 3PE le thibelang kutu ho khopama ka lebaka la ho bola nakong ea polokelo.

4. Laola ka thata boleng ba ho sila ba seam sa welding se boloketsoeng pheletsong ea liphaephe.Bokantle ba groove ea polyethylene ho weld e tšoana le likarolo tse ling tsa 'mele oa phala.Boloka phofo ea epoxy nako e telele ho feta 20mm ho thibela botlaaseng ba phofo ea epoxy ho weld hore e se ke ea senyeha pele le ho baka 3PE anti-corrosion layer ea warp.

Ela hloko ho siloa ha li-welds tsa lipeipi:

1) Ho tloha qalong ea tjheseletsa seam sila ho polyethylene chamfer, ho na le e lokela ho ba karolo e bataletseng ea polyethylene lera ea 10-20mm le ha ho feteletseng tjheseletsa bophahamo ba le tšoanang le phala 'mele ho etsa bonnete ba extrusion le tlamahano ea polyethylene. groove qetellong ea phala boleng.

2) Matlafatso ea seam ea weld ka mor'a ho sila e lokela ho ba ka hohle kamoo ho ka khonehang ka 'mele oa phala,' me ha hoa lokela ho ba le matlafatso e hlakileng ho thibela phofo ea epoxy hore e se ke ea belisoa ha ho sila chamfer ea polyethylene lera.

3) The chamfer ea top undressed top of weld le karolo ea phetoho ea sebaka se lokisitsoeng le eona e lokela ho tšoana le chamfer ea polyethylene layer (≤30°) e le hore matla a ho penya a "squeeze roller" a ka hatella ka mokhoa o ts'oanang lera la polyethylene Ho thibela lera la polyethylene hore le se ke la phunya ka lebaka la ho khomarela ho futsanehileng ha lera le khahlanong le senya ka har'a groove.

5. Ho roala phofo ea epoxy ea karolo e bolokiloeng e ka liehisa ho loana ka bohale ho bakoang ke ho senya feela ha tšireletso e phethiloe.Pipe ea lapeng e qetellang polyethylene bevel processing e etsoa ka ho sila lebili la terata ea tšepe, e tla senya phofshoana ea phofo ea epoxy.Bevel e lokela ho etsoa ho e-na le hoo, 'me karolo e ka tlaase ea thipa e lokela ho lekanyetsoa ke sesebelisoa ho laola botebo ba ho itšeha ha sesebelisoa, e le hore se se ke sa senya lesela la phofo ea epoxy.
