Ukuqonda i-ASTM A252 Pipe: Ubungakanani, Umgangatho, kunye nezicelo
Umbhobho we-Astm A252licandelo elibalulekileyo kwizicelo zesakhiwo kumacandelo amaninzi, ingakumbi kwiprojekthi zokwakha kunye neziseko zophuhliso. Le bhlog iza kujonga ubungakanani, umgangatho, kunye nokusetyenziswa kwepayipi ye-ASTM A252, igqamisa amandla omenzi ophambili oseCangzhou, kwiPhondo laseHebei.
Yintoni ipayipi ye-ASTM A252?
Ubungakanani bepayipi ye-Astm A252yinkcazo eyenziwe yi-American Society for Testing and Materials (ASTM) echaza iimfuno zombhobho wentsimbi odibeneyo nongenamthungo osetyenziswa kwizicelo zokufaka iintsika. Lo mgangatho ugxile ekuqineni kwesakhiwo sombhobho kunye nokuqina kwawo, okwenza ukuba ufanelekele iziseko, iibhulorho, kunye nezinye izicelo ezinzima.
Yintoni ipayipi ye-ASTM A252?
I-ASTM A252 yinkcazo enegunya eyenziwe yi-American Society for Testing and Materials (ASTM), ngokukodwa kwiipayipi zentsimbi ezisetyenziswa ekuqhubeni iinqwaba kunye nezicelo zokuxhasa ulwakhiwo olunzulu. Lo mgangatho uchaza ngokungqongqo ukwakheka kweekhemikhali, iipropati zoomatshini, ukunyamezelana kobukhulu kunye neendlela zokuvavanya iipayipi zentsimbi, ukuqinisekisa ukuthembeka kwazo okuhle kakhulu kwisakhiwo, ukuqina kunye nomthamo wokuthwala umthwalo. Lukhetho olufanelekileyo kwiiprojekthi zesiseko ezifana neeBridges, izakhiwo eziphakamileyo kunye namazibuko.
Ubukhulu bePipe ye-Astm A252ubukhulu kunye neenkcukacha
Iipayipi ze-ASTM A252 zahlulwe zibe ziiklasi ezintathu ngokweemfuno zamandla: i-GR 1, i-GR 2, kunye ne-GR 3, apho i-GR 3 inamandla aphezulu. Uluhlu lobukhulu bayo luyakwazi ukuguquguquka kwaye lunokuhlangabezana neemfuno ezahlukeneyo zobunjineli.
Ububanzi obungaphandle (OD): Ukusuka kwii-intshi ezi-6 ukuya kwii-intshi ezingama-60, kunye nobukhulu obukhulu bunokuveliswa.
Ubukhulu bodonga (WT): Ngokwesiqhelo phakathi kwe-0.188 intshi kunye ne-0.500 intshi, kwaye inokulungiswa ngokweemfuno zokumelana nokucinezelwa nokugoba.
Ubude: Ubude obuqhelekileyo buziimitha ezingama-20 okanye iimitha ezingama-40. Imveliso eyenzelwe wena ikwaxhaswa ngokweemfuno zeprojekthi.
Olu luhlu olubanzi lobukhulu luqinisekisa ukuba iinjineli zinokukhetha ezona nkcukacha zingabizi kakhulu kwiiprojekthi ezithile.
Umbhobho we-ASTM A252 usetyenziswa kwiindlela ezahlukeneyo zokusebenza, kuquka:
1. Ukufaka iipayipi: Le mibhobho idla ngokusetyenziswa njengeepayipi zomhlaba kwiiprojekthi zokwakha ukubonelela ngozinzo nokuxhasa isakhiwo.
2. Iibhulorho: Amandla nokuqina kombhobho we-ASTM A252 kuyenza ibe lolona khetho lufanelekileyo lokwakha iibhulorho, apho inokumelana nemithwalo enzima kunye neemeko zokusingqongileyo.
3. Izakhiwo zaselwandle: Ukumelana nokugqwala kwezi payipi kuvumela ukuba zisetyenziswe kwiindawo zaselwandle ezifana needokhi kunye neepiers.
4. Ioyile neGesi: Ngenxa yokwakhiwa kwayo okomeleleyo, umbhobho we-ASTM A252 usetyenziswa nakwishishini leoyile negesi ukuthutha ulwelo kunye neegesi.
Isishwankathelo
Ngamafutshane, ipayipi ye-ASTM A252 yinxalenye ebalulekileyo kwiintlobo ngeentlobo zezicelo zesakhiwo, inika ukuthembeka namandla. Le fektri eseCangzhou, kwiPhondo laseHebei, ngumvelisi ophambili wolu hlobo lwepayipi, eqinisekisa ukuba iimveliso zayo ziyahlangabezana nemigangatho ephezulu yomgangatho. Ngokuzibophelela ekugqweseni nasekugxileni kwizinto ezintsha, inkampani iyaqhubeka nokudlala indima ebalulekileyo kwicandelo lokwakha neziseko zophuhliso. Nokuba ubandakanyeka kwiprojekthi yokwakha enkulu okanye ufuna isisombululo sepayipi esithembekileyo, ipayipi ye-ASTM A252 lukhetho oluhle kakhulu kwiimfuno zakho.
