Kukho iintlobo ezininzi zentsimbi engatyiwa, kwaye umahluko wexabiso nawo mkhulu ngokwentelekiso. Ukusuka kwimbono yeendlela zokuvelisa, kukho iindidi zeplate, iintlobo zokuphosa, kunye neentlobo zokubumba. Ngokubanzi, iintlobo zeepleyiti zingabizi kakhulu, kuba uninzi lwamacwecwe ensimbi engenasici Iveliswa ngobuninzi, kwaye ixabiso liphantsi. Iindleko ze-castings ziyahluka ngokobunzima besakhiwo. I-Forgings icutshungulwa ngesiseko se-ingots yensimbi engenasici, ngoko ke ixabiso liphezulu kunelo li-cast stainless steels eziqhelekileyo.

Insimbi engenasici I-Thimbles idla ngokusetyenziswa ekwakheni amagumbi angaphantsi ukukhusela imibhobho okanye amakhonkco entsimbi aququzelela ukufakwa kombhobho.

Ukuhlelwa kwe-casing: i-casing eqinile, i-flexible waterproof casing, i-tube ye-tube casing, kunye ne-metal casing.
