Amashubhu ensimbi angenamthungoahlukahlukene kakhulu.Inhloso evamile yamashubhu ensimbi engenamthungo asongwa kusukela kunsimbi evamile ye-carbon structural, insimbi yesakhiwo sengxubevange ephansi noma insimbi yesakhiwo sengxubevange, ephumayo enkulu kakhulu, futhi asetshenziswa kakhulu njengamapayipi noma izingxenye zesakhiwo zokuthutha uketshezi.

Ngokusetshenziswa okuhlukahlukene, zihlukaniswe izigaba ezintathu:

a.Ukuhlinzeka ngokwamakhemikhali kanye nezakhiwo zemishini;

b.Ukuhlinzeka ngokuhambisana nezakhiwo zemishini;

c.Nikeza ngokokuhlolwa kwe-hydraulic.Ukuze amapayipi ensimbi enikeziwe ngokusho

ezigabeni u-a no-b, uma zisetshenziselwa ukumelana nokucindezela kwamanzi, ukuhlolwa kwe-hydraulic kuyadingeka.

Amapayipi akhethekile angenamthungo ahlanganisa amapayipi angenamthungo, amandla amakhemikhali, amapayipi angenamthungo we-geology kanye namapayipi angenamthungo e-petroleum.

Amapayipi ensimbi angenamthungo anendawo ephambanayo engenalutho futhi asetshenziswa kabanzi njengamapayipi okuthutha uketshezi, njengamapayipi athutha uwoyela, igesi yemvelo, igesi, amanzi, nezinto ezithile eziqinile.Uma kuqhathaniswa nensimbi eqinile njengensimbi eyindilinga, ipayipi lensimbi lilula ngesisindo uma linamandla afanayo aguquguqukayo kanye ne-torsional.Kuyinsimbi eyongayo futhi isetshenziswa kakhulu ekwenzeni izingxenye zesakhiwo kanye nezingxenye eziwumshini, njengezinduku zokumba i-petroleum, izinsimbi zokuhambisa izimoto, namabhayisikili Amapayipi ensimbi nezinye izikafula ezisetshenziswa ekwakheni ukwenza izingxenye ezimise okweringi. ngcono ukusetshenziswa kwempahla, ukwenza kube lula izinqubo zokukhiqiza, ukonga izinto zokwakha namahora okucubungula, futhi sekusetshenziswe kabanzi kumapayipi ensimbi.
