I-ASTM PIPEP

I-ASTM PIPEP
Amapayipi ensimbi adlala indima ebalulekile kwizicelo zezimboni, ikakhulukazi emikhakheni yokwakha, i-petroleum, imboni yamakhemikhali kanye nemishini yokukhiqiza imishini. Amapayipi ensimbi astm, okungukuthi, amapayipi ensimbi akhiqizwa ngokuya ngamazinga omphakathi waseMelika wokuhlola kanye nezinto zokwakha (ASTM), asetshenziswa kabanzi ngenxa yamandla awo aphezulu, ukumelana nokugqwala nokusebenza okuhle kwe-welding.

Isibonelo, i-ASTM A53 Standard ihlanganisa amapayipi ensimbi ye-carbon ye-Piping Systems, kuyilapho i-ASTM A106 Standard isebenza kumapayipi e-Carbon engenamthungo ezinhlamvu ezishisa ezingenamthungo. Ngaphezu kwalokho, i-ASTM A500 Standard icacisa izidingo zamapayipi e-carbon elibandayo namapayipi enziwe ngezingxenye ezikhethekile zezakhiwo. Lapho ukhetha ipayipi elifanele lensimbi, hhayi kuphela amazinga ngosayizi, njengobubanzi obungaphandle, ububanzi obudongeni nobude, kodwa futhi nezindinganiso ezibonakalayo, kufaka phakathi ibanga lensimbi kanye nokwakheka kwamakhemikhali, kufanele kubhekwe. Ngezinhlelo ezithile zobunjiniyela, kubalulekile ukukhetha ukucaciswa kwensimbi ye-ASTM efanelekile nezinto zokwakha ukuqinisekisa ukuqina nokuphepha kwesakhiwo.

I-American Standard (ASME) isungule uchungechunge lwamazinga acacisiwe amapayipi ensimbi ukuqinisekisa ikhwalithi nokusebenza kwamapayipi ensimbi. Isibonelo, i-ASME B36.10M iyindinganiso yamapayipi ensimbi ahlanganisiwe futhi angenamishini, acacisa ngokuningiliziwe izidingo zosayizi, impahla, izici zemishini, izindlela zokukhiqiza kanye nezindlela zokuhlola zamapayipi ensimbi. Mayelana nobubanzi bokucaciswa, ububanzi obungaphandle kwamapayipi ensimbi angenathule e-ansi imvamisa kumasentimitha ayi-1/2, ama-intshi ama-2, ngenkathi ubukhulu be-inches, ngenkathi ushushisi lodonga ), okunjengo-Sch 40, SSSSS 80, njll Izinqubo ezahlukahlukene ze-welding kanye nokucaciswa kwezinto ezibonakalayo zisetshenziselwa izimo ezihlukile zohlelo lokusebenza, njengezinhlaka zobunjiniyela ezijwayelekile kanye nezokuhamba eziphansi zengcindezi. Ukuqonda lezi zindinganiso kubalulekile onjiniyela kanye nabaqeqeshiwe ngoba bahlobene ngokuqondile nokuphepha kanye nokwethenjwa kwamaphrojekthi wobunjiniyela. .
