Amashubhu ensimbi angenamthungo asetshenziswa kakhulu.
1. Amashubhu ensimbi angenamthungo ngezinjongo ezijwayelekile asongwa ngensimbi evamile ye-carbon structural, insimbi yesakhiwo se-alloy ephansi noma insimbi yesakhiwo sengxubevange, ephumayo enkulu kakhulu.Asetshenziswa kakhulu njengamapayipi noma izingxenye zesakhiwo zokudlulisa uketshezi.
2, ngokuya ngokusetshenziswa kwezigaba ezahlukahlukene zokuhlinzekwa:
A. Ngokusho kokwakheka kwamakhemikhali kanye nezakhiwo zemishini;
B. Ukuhlinzeka ngokuhambisana nezakhiwo zemishini;
C. Nikeza ngokuya ngokuhlolwa kwe-hydrostatic.Amapayipi ensimbi ahlinzekwe kumakilasi u-a no-b nawo azohlolwa i-hydrostatic uma esetshenziselwa ukumelana nomfutho woketshezi.
I-3, ishubhu elingenamthungo elinenhloso ekhethekile elineshubhu elishisayo elingenamthungo, amandla amakhemikhali ane, ipayipi lensimbi elingenamthungo le-geological kanye neshubhu le-petroleum engenamthungo nokunye.
Ipayipi lensimbi elingenamthungo linengxenye ephambanayo engenalutho, inani elikhulu elisetshenziselwa ukudlulisa amapayipi oketshezi, njengamapayipi okuthutha uwoyela, igesi yemvelo, igesi, amanzi kanye namanye aqinile.Uma kuqhathaniswa nensimbi eqinile njengensimbi eyindilinga, ipayipi lensimbi linokugoba okufanayo namandla okugoqa futhi lilula ngesisindo.Kuwuhlobo lwensimbi yesigaba esiphambanayo eyongayo.
