1. Uphawu oluphambili lwesiqhelo ngokubanziiityhubhu zentsimbi ezingenamthungo kukuba azinayo i-welding seams kwaye ziyakwazi ukumelana noxinzelelo olukhulu.Imveliso ingaba rhabaxa kakhulu okanye izotywe kubanda.

2. Ubukhulu bomngxuma wangaphakathi kunye nodonga lwangaphandle lombhobho wensimbi ochanekileyo owenziwe ngokubanda unokunyamezela okungqongqo kunye noburhabaxa.

Iimpawu zemibhobho yentsimbi echanekileyo etsalwa ngokubanda (eqengqiwe):

1. I-diameter yangaphandle incinci;

2. Ukuchaneka okuphezulu kungasetyenziselwa ukuveliswa kwebhetshi encinci;

3. Iimveliso ezigqityiweyo ezibandayo (eziqengqelekayo) zinokuchaneka okuphezulu kunye nomgangatho omhle womphezulu;

4. Ummandla onqamlezileyo wombhobho wensimbi unzima ngakumbi;

5. Ukusebenza kombhobho wensimbi kuphezulu, kwaye isinyithi sinobunzima.
