Umbhobho wentsimbi ongenamthungoI-ASTM A53, SCH40, Gr.B ngumbhobho wensimbi ophezulu osetyenziswa ngokubanzi kwiimarike, kunye nokusebenza kakuhle kunye neendawo ezahlukeneyo zesicelo. Oku kulandelayo sisingeniso kwiinzuzo zalo mbhobho wentsimbi:

Izinto eziphathekayo kunye noMgangatho
I-ASTM A53umgangatho luphawu olungqongqo kwimibhobho yentsimbi engenamthungo kushishino lwentsimbi yase-US, ikakhulu esetyenziselwa i-oyile, igesi yendalo, umphunga kunye neminye imibhobho. Lo mbhobho wensimbi wenziwa nge-carbon steel okanye i-alloy iron ephantsi. IBanga B (Gr.B) libonisa ukuba umbhobho unamandla amakhulu kunye nokuxhatshazwa koxinzelelo kwaye ufanelekile kwiindawo eziphakamileyo kunye noxinzelelo oluphakathi. I-SCH40 ibhekisela kumgangatho wobunzima bodonga lombhobho, oqinisekisa ukuba umbhobho unokumelana nokubola okwaneleyo kunye nokunyanzeliswa koxinzelelo.

Inkqubo yokuvelisa kunye nomgangatho
Lo mbhobho wentsimbi wamkela ubuchwephesha bokuvelisa umbhobho wentsimbi ongenamthungo ukuze kuqinisekiswe umgangatho wemveliso ozinzileyo, umphezulu wombhobho ogudileyo, akukho ziphene zokuwelda, kunye nokumelana noxinzelelo olugqwesileyo kunye nokumelana nomhlwa. Ngokuhlola umgangatho ongqongqo, iyahlangabezana neemfuno zeI-ASTM A53umgangatho wokuqinisekisa ukuba amandla, ubulukhuni, ukudumba kunye nokuxhathisa umhlwa kumbhobho wentsimbi ngamnye uyahlangabezana nemigangatho yoshishino.

Iinkcukacha kunye nobungakanani besicelo
Umbhobho wentsimbi ongenamthungo uneenkcukacha ezahlukeneyo, kubandakanywa iidamitha zangaphandle eziqhelekileyo ukusuka kwi-1/8 "ukuya kwi-30", kunye nobukhulu bodonga bunokwenziwa ngokwezifiso ngokweemfuno. Isetyenziswa ngokubanzi kwimimandla yepetroleum, iikhemikhali, amandla ombane, ukwakhiwa kweenqanawa, oomatshini, njl.njl., ifanelekile ngakumbi kwiinkqubo zemibhobho ezithutha i-media media efana namanzi, i-oyile kunye negesi.

Isetyenziswa ngokubanzi
I-ASTM A53umbhobho wensimbi ongenamthungo ungasetyenziselwa imibhobho yokuhambisa i-high-pressure, izakhiwo zokwakha, iipayipi zebhoyili, i-oyile kunye negesi yendalo yokuhambisa imibhobho, njl., ukulungelelanisa kwiindawo ezahlukeneyo zokusebenza eziyinkimbinkimbi, ukubonelela ngokusebenza okuthembekileyo kokuhamba kunye neziqinisekiso zokhuseleko.
