Umbhobho wentsimbi ongenamthungoI-ASTM A53, SCH40, Gr.B ngumbhobho wentsimbi osemgangathweni ophezulu osetyenziswa kakhulu kwimarike, osebenza kakuhle kwaye uneendawo ezahlukeneyo zokusetyenziswa. Oku kulandelayo kukwazisa ngeenzuzo zalo mbhobho wentsimbi:

Izixhobo kunye neMigangatho
I-ASTM A53umgangatho yinkcazo engqongqo yemibhobho yentsimbi engenamthungo kwishishini lentsimbi laseMelika, esetyenziswa kakhulu kwioyile, igesi yendalo, umphunga kunye neminye imibhobho. Lo mbhobho wentsimbi wenziwe ngentsimbi yekhabhoni okanye intsimbi e-alloy ephantsi. Udidi B (Gr.B) lubonisa ukuba umbhobho unamandla aphezulu kunye nokumelana noxinzelelo kwaye ufanelekile kwiindawo ezinoxinzelelo oluphakathi noluphezulu. I-SCH40 ibhekisa kumgangatho wobukhulu bodonga lombhobho, oqinisekisa ukuba umbhobho unokumelana nokugqwala okwaneleyo kunye nomthamo wokuthwala uxinzelelo.

Inkqubo yemveliso kunye nomgangatho
Le pipe yentsimbi isebenzisa ubuchwepheshe obuphambili bokuvelisa imibhobho yentsimbi engenamthungo ukuqinisekisa umgangatho wemveliso ozinzileyo, umphezulu wemibhobho ogudileyo, akukho ziphene zokudityaniswa, kunye nokumelana okugqwesileyo koxinzelelo kunye nokumelana nokugqwala. Ngokuhlola umgangatho ngokungqongqo, iyahlangabezana neemfuno zeI-ASTM A53umgangatho ukuqinisekisa ukuba amandla, ubulukhuni, ukuguguleka kunye nokumelana nokugqwala kombhobho ngamnye wentsimbi kuyahlangabezana nemigangatho yoshishino.

Iinkcukacha kunye nobubanzi besicelo
Umbhobho wentsimbi ongenamthungo uneempawu ezahlukeneyo, kuquka ububanzi obuqhelekileyo bangaphandle obuqala kwi-1/8" ukuya kwi-30", kwaye ubukhulu bodonga bunokulungiswa ngokweemfuno. Isetyenziswa kakhulu kwicandelo le-petroleum, iikhemikhali, amandla ombane, ukwakhiwa kweenqanawa, oomatshini, njl.njl., ifanelekile ngakumbi kwiinkqubo zemibhobho ezithutha izinto ezimanzi ezifana namanzi, ioyile, kunye negesi.

Isetyenziswa kakhulu
I-ASTM A53umbhobho wentsimbi ongenamthungo ungasetyenziselwa imibhobho yokudlulisa enoxinzelelo oluphezulu, izakhiwo zezakhiwo, imibhobho yebhoyila, imibhobho yokudlulisa ioyile kunye negesi yendalo, njl.njl., ilungelelaniswe neendawo ezahlukeneyo zokusebenza ezinzima, inika ukusebenza okuthembekileyo kothutho kunye neziqinisekiso zokhuseleko.
