Izinzuzo ze-A252 Grade 2 Steel Pipe Spiral Submerged Arc Welded Polypropylene Lined Pipe

 Ipayipi eline-polypropyleneinikeza izinzuzo eziningana lapho isetshenziswa ngokuhambisana nokushiselwa kwe-arc engaphansi kwamanzi e-spiral ye-A252 Grade 2 yepayipi yensimbi.Enye yezinzuzo eziyinhloko ukumelana nokugqwala okuza ne-polypropylene.Ngokufaka ipayipi lensimbi nge-polypropylene, indawo yangaphakathi ivikelwe ezintweni ezigqwalayo, iqinisekisa isikhathi eside nokuthembeka kwesistimu yamapayipi.Lokhu kubaluleke kakhulu ekusetshenzisweni lapho amapayipi evezwa kumakhemikhali anonya noma izimo zemvelo.

Ukwengeza, amapayipi anemigqa ye-polypropylene aziwa ngobushelelezi bangaphakathi bawo, okusiza ukunciphisa ukungqubuzana nokuthuthukisa ukugeleza koketshezi ngaphakathi kwamapayipi.Lokhu kwandisa ukusebenza kahle futhi kunciphisa ukusetshenziswa kwamandla, okwenza kube inketho ekhangayo ezinhlobonhlobo zezinhlelo zokusebenza zezimboni nezentengiso.

Enye inzuzo enkulu yokusebenzisa ipayipi elinomugqa we-polypropylene ekushiseleleni i-arc engaphansi kwe-spiral ukuvikela okungeziwe ekugqokeni.I-polypropylene lining isebenza njengesithiyo, ivikela amapayipi ensimbi emonakalweni we-abrasive futhi inciphisa isidingo sokunakekelwa njalo nokulungiswa.

Ngaphezu kwezinzuzo ezihlinzekwa yi-polypropylene lining, inqubo ye-spiral submerged arc welding nayo iyisici esibalulekile ekudaleni uhlelo lwamapayipi oluqinile noluthembekile kusetshenziswa.Ipayipi lensimbi i-A252 yeBanga lesi-2.Lobu buchwepheshe bokushisela busebenzisa inqubo yokushisela i-arc flux-cored ekhiqiza ama-welds aqinile futhi abushelelezi ahlangabezana nezindinganiso eziphakeme ezidingekayo kumapayipi ezimboni.
