Ngokuncipha kwamandla nezinsiza, imikhumbi yamapayipi ithutha igesi eyandayo, itiyela kanye neminye imikhiqizo kaphethiloli esezingeni eliphansi, futhi ukwakhiwa kwamapayipi olwandle nakho kuqhubeka ngokuqhubekayo. Ukuthuthukiswa akuzange kuphazamiseke. Okulandelayo yisingeniso kobunye ubuchwepheshe.
Ukushisa okuphezulu ukumelana ne-3pe anticorrosion
Ukwelashwa okungaphezulu Izinga lokuqhuma kwesibhamu sangaphandle 2.5, i-tattoo engama-microns angama-60. Ngemuva kokudubula nokususwa kokugqwala, ingaphezulu lepayipi lensimbi lihlanzwa nge-phosphoric acid ne-chromate ukuze kukhishwe uthuli olufakwe ebusweni bepayipi lensimbi.
Isendlalelo sokuqala sisebenzisa i-FBE evimbela ukugqwala kwe-epoxy powder esikhundleni sempushana evamile ye-3pe evimbela ukugqwala, ethuthukisa umsebenzi wamakhemikhali ongaphezulu futhi ithuthukise ukunamathela nge-FBE. Izinga lokushisa lokushintsha kwengilazi le-FBE liphakathi kuka-100-150 ° C, futhi ukuthambisa kwe-Vicat kwe-adhesive Indawo yokuthambisa ye-HDPE ingu-124 ° C ngenxa yokusabalalisa kwayo isisindo samangqamuzana amancane, izakhiwo eziqinile kanye nokumelana okuqinile nokulimala komshini.
Ungqimba lwesibili lubaluleke kakhulu. Ukusebenza okuphezulu kwezinga lokushisa kwe-3pe kuncike ezintweni zezinto zokusetshenziswa. Njengamanje, izinto zokusetshenziswa ezisebenza kahle kakhulu ezithuthukiswe ngokuzimela yi-Xinlong Anticorrosion zisekelwe eziphethweni ezithathwe ekusebenzeni kokufakwa kwezimboni. Izinga lokushisa elithambile le-adhesive lincishiswa ngo-20 ° C, izinga lokushisa eliphezulu lokusebenza kwe-3pe eguquliwe ye-anti-corrosion layer iyatholakala.
