1. Kubaimibhobho ngeemfuno eziphezulu zokucheba, ngenxa yokusetyenziswa kwerhasi engalinganiyo ngabasebenzisi, ukuguquguquka rhoqo koxinzelelo lwemibhobho, kunye noxinzelelo olutshintshanayo oluthwalwa yimibhobho yentsimbi, iziphene ezikhoyo kwimibhobho ziya kwanda phantsi koxinzelelo olutshintshanayo.Imibhobho yentsimbi edityanisiweyo ene-Spiral ene-welds ezininzi kunye namathuba aphezulu okuba neziphene azinakuqinisekisa ukusebenza kwazo okuqhelekileyo.

2. Lo mbhobho udlula kwindawo ene-seismic fault okanye kwindawo yengingqi yenyikima enobunzulu obuphezulu.Ngenxa yemisebenzi yejoloji rhoqo kula macandelo, i-longitudinal okanye i-axial alternating stress inokuveliswa kumbhobho.Zininzi i-spiral welds, kwaye iziphene ezinokwenzeka ziphezulu kunaleyo ye-arc welded steel pipes.Ngaphantsi koxinzelelo lwexesha elide, ukuba nokwenzeka kweengozi kwimibhobho yentsimbi edityanisiweyo iphezulu kakhulu kunemibhobho yentsimbi edityanisiweyo ye-arc.Ngoko ke, imibhobho yentsimbi ye-arc ephantsi kwamanzi kufuneka isetyenziswe kule ndawo.

3. Kwimibhobho eneemfuno eziphezulu zangaphakathi kunye nezangaphandle ezichasene ne-corrosive, iipayipi zensimbi ezifakwe emanzini kufuneka zisetyenziswe.Imibhobho yentsimbi edityanisiweyo ye-arc edityanisiweyo ineentsimbi ezininzi, kwaye ubude bomthungo we-weld buphezulu ngokubanzi kunobo bemibhobho yentsimbi edityanisiweyo ye-arc.Xa umbhobho wensimbi ukhuselwe kwi-corrosion yangaphakathi nangaphandle, ukudibanisa kwezinto ezichasene ne-corrosive kunye nombhobho ongenanto awunamandla njengepayipi yensimbi edibeneyo ye-arc welded, kwaye i-anti-corrosive effect ayiyi kufakwa emanzini.

4. Ngobunjineli obubalulekileyo bomnqamlezo, imibhobho yentsimbi ye-arc ephantsi kwamanzi kufuneka isetyenziswe.Ekubeni ukugcinwa kunye nokulawulwa kwexesha elizayo kuya kuba nzima ngakumbi kunamacandelo aqhelekileyo emibhobho, ukusetyenziswa kwemibhobho yentsimbi ye-arc ephantsi kwamanzi kunye nokusebenza kubaluleke kakhulu.

1. Kwiikhonkco ezibuthathaka kwimibhobho, njengemibhobho ye-elbow eshushu, imibhobho yentsimbi ye-arc ephantsi kwamanzi kufuneka isetyenziswe.Ngenxa yotshintsho kwindlela, i-elbow eshushu ingakwazi ukumelana namandla amakhulu angaphakathi nangaphandle kunecandelo lombhobho elichanekileyo lombhobho oqhelekileyo.Ngenxa yezinto ezahlukeneyo kwinkqubo yokuthintela, uxinzelelo lwayo alulula ukuphelisa, kwaye luyikhonkco elibuthathaka kumbhobho omde.Ukusetyenziswa kwemibhobho yentsimbi ene-arc edibeneyo eneempawu ezintle ezibanzi kunokwenza ezi ntsilelo.
