Ipayipi lensimbi eliphehliwekuyindlela yokuthuthukisa ukumelana nokugqwala kwepayipi lensimbi kanye nomhlobiso walo omuhle.Njengamanje, indlela evame ukusetshenziswa kakhulu yokufaka uthayela amapayipi ensimbi i-hot-dip galvanizing.

Inqubo yokukhiqiza amashubhu ensimbi angenamthungo ingahlukaniswa ngezinhlobo eziyisisekelo zamashubhu ensimbi ashisiwe (extrusion), abandayo (adonswe), kanye namashubhu ensimbi anwetshiwe.Ngokwenqubo yokukhiqiza, amapayipi ashiselwe angahlukaniswa abe: amapayipi ensimbi ashiselwe ngomthungo oqondile, amapayipi ensimbi ashiselwe i-arc angaphansi kwamanzi, amapayipi ensimbi anezinqe ezishiselwe izinqe, namapayipi ensimbi anwetshiwe.

Ukuthuthukiswa kobuchwepheshe bokukhiqiza amapayipi ensimbi kwaqala ngokukhuphuka kokukhiqizwa kwamabhayisikili.Akukhona nje kuphela ukuthi ipayipi lensimbi elisetshenziselwa ukudlulisa uketshezi kanye nezinto eziqinile eziyimpuphu, ukushintshanisa amandla ashisayo, izingxenye zomshini wokukhiqiza neziqukathi, liphinde libe yinsimbi yokonga.Ukukhiqiza amagridi esakhiwo sensimbi, izinsika nezisekelo zemishini ngamapayipi ensimbi kunganciphisa isisindo, konge u-20 kuya ku-40% wensimbi, futhi kubone ukwakhiwa kwefekthri ngomshini.

Ipayipi lensimbi linobudlelwano obukhulu nokuthuthukiswa komnotho wezwe kanye nokuthuthukiswa kwezinga lempilo yabantu, okungcono kakhulu kunezinye izinsimbi.Kusukela ezintweni zikagesi zabantu zansuku zonke, ifenisha, ukuphakelwa kwamanzi kanye nokukhipha amanzi, ukuhlinzekwa kwegesi, izinsiza zokungenisa umoya kanye nokushisisa kuya ekwakhiweni kwemishini nemishini yezolimo ehlukahlukene, ukuthuthukiswa kwezinsiza ezingaphansi komhlaba, izibhamu, izinhlamvu, imicibisholo, amarokhethi asetshenziswa ekuvikelweni kwezwe kanye nendawo akuhlukaniseki. kusukela emapayipini ensimbi.
