Imibhobho e-Spiral welded (isaw) igqunyelelwa ngaphandle, kwaye uninzi lwayo lungcwatywa phantsi komhlaba xa lusetyenziswa, ukuze kube lula ukurhwaphiliza nokugqwala. Ukuze kuqinisekiswe ukuhamba kakuhle kombhobho, umbhobho we-spiral welding kufuneka ube nokuxhathisa okuqinileyo ku-corrosion. Wakuba umbhobho udliwe, uya kubangela ukuvuza kwe-oyile negesi, okungayi kuphazamisana nokuthuthwa kuphela, kodwa kungcolise indalo esingqongileyo, kwaye kunokubangela umlilo nokwenzakala. Abavelisi bemibhobho edityanisiweyo ye-Spiral baya kukuxelela malunga nezinto ezibangela ukubola kwemibhobho edityanisiweyo:

Izizathu zomhlwa wombhobho we-spiral welded:

1. Ukungaphumeleli kokubola.

Xa umbhobho wakhiwe, kuyimfuneko ukwenza umsebenzi omhle wokunqanda ukubola okanye ukusebenzisa ngokuthe ngqo imibhobho ye-anti-corrosion spiral steel. Isizathu sokubola kombhobho kukuba i-anti-corrosion layer yombhobho yonakaliswe. Nje ukuba umaleko wokuchasana nomhlwa kunye nomphezulu wombhobho wohlulwe, ngokwemvelo uya kubangela ukusilela kokuchasana nokudusa. Olu luhlobo lweleli kwakhona. Kufuneka sikhethe umbhobho odityanisiweyo we-anti-corrosion spiral xa kuthengwa i-spiral welded pipe.

2. Impembelelo yeemeko zangaphandle.

Into ephambili kukuqala ukujonga iimpawu kunye neqondo lokushisa eliphakathi elijikeleze umbhobho, kwaye ingaba i-medium ejikeleze umbhobho igqwala. Ngenxa yokuba i-corrosiveness ye-medium inxulumene ngokusondeleyo kwii-microorganisms ezahlukeneyo eziqulethwe emhlabeni. Kwaye ukuba ngumbhobho omde, ubume bemeko yomhlaba bunzima ngakumbi. Ukongeza, iqondo lobushushu lokusingqongileyo apho umbhobho ukhoyo liya kuchaphazela ukubola kombhobho we-spiral welded. Ukuba iqondo lokushisa liphezulu, izinga lokubola liya kukhawuleza, ngelixa izinga lokushisa liphantsi, izinga lokubola liya kuthotywa.
