Kunezinhlobo eziningi zeamapayipi ensimbi engagqwali, ngokusetshenziswa okuhlukile, izidingo ezahlukene zobuchwepheshe, nezindlela ezihlukene zokukhiqiza. I-diameter yangaphandle yepayipi yensimbi ekhiqizwayo okwamanje ingu-0.1-4500mm, futhi ubukhulu bodonga buyi-0.01-250mm.
Ipayipi lensimbi engagqwali liyinsimbi eyindilinga eyindilinga engenalutho, esetshenziswa kabanzi ku-petroleum, amakhemikhali, ezokwelapha, ekudleni, embonini yokukhanya, izinsimbi zomshini kanye namanye amapayipi ezimboni kanye nezingxenye zesakhiwo semishini. Ngaphezu kwalokho, lapho ukugoba namandla okugoqa kufana, isisindo silula, ngakho-ke sisetshenziswa kabanzi ekwenzeni izingxenye zemishini kanye nezakhiwo zobunjiniyela. Ibuye isetshenziswe ngokujwayelekile njengefenisha nezitsha zasekhishini.
Izakhiwo zepayipi lensimbi engagqwali: ukumelana nendawo ngaphansi kuka-1000M; ukuvikela ukugqoka; enwebekayo; ukumelana kwamakhemikhali okuhle kakhulu; ukumelana okuhle kwe-alkali yensimbi ne-asidi; ukuqina okuqinile; i-flame retardant.
