I-ASTM A53Umgangatho nguMbutho waseMelika uVavanyo kunye nezixhobo. Umgangatho oqhelekileyo ugubungela imibhobho yobukhulu bemibhobho kunye nobubanzi kwaye isebenza kwiinkqubo zokucoca ezisetyenziselwa ukuthutha iigesi, ulwelo kunye nolunye ulwelo. I-ASTM A53 I-Piping isetyenziswa kwiindawo ezisebenza kwimizi-mveliso nakwezomatshini, nakwimizi-mveliso yokwakha yokubonelela ngamanzi, ukufudumeza kunye neenkqubo zomoya.

Ngoku kaI-ASTM A53Imigangatho, imibhobho inokwahlulwa ibe ziindidi ezimbini: chwetheza f kwaye chwethe i-E Zombini iintlobo zemibhobho zifuna unyango lobushushu ukuqinisekisa ukuba iipropathi zabo zoomatshini kunye nokubekwa kwekhemikhali ziyafezekisa iimfuno ezisemgangathweni. Ukongeza, iimfuno zomphezulu zombhobho kufuneka zihambelane nezibonelelo ze-ATTM A530 / A530M yokuqinisekisa umgangatho wayo wokubonakala.

Imithombo yekhemikhali ye-ASTM A53 Imibhobho esemgangathweni ilandelayo Ezi zithintelo zekhemikhali ziqinisekisa amandla, ubunzima kunye nokunganyangeki kombhobho.

Ngokwemigangatho yoomatshini, i-ASTM A53 ifuna ukuba amandla e-thensile kunye namandla okuvelisa imibhobho ayingaphantsi kwe-330mpa ne-205MPA ngokwahlukeneyo. Ukongeza, inqanaba le-Elongwang loMbhobho likwaneemfuno ezithile ukuqinisekisa ukuba ayihambelani nokuqhawuka okanye ukuthotyelwa ngexesha lokusetyenziswa.

Ukongeza kubume bemichiza kunye neepropathi zoomatshini, i-ASTM A53 ibonelela ngemigaqo eneenkcukacha malunga nobungakanani kunye nomgangatho wokubonakala. I-PIIF SITER ukusuka kwi-1/8 i-intshi ukuya kwi-intshi ezingama-26, ngeendlela ezahlukeneyo zodonga. Umgangatho wokubonakala weplanga ufuna indawo egudileyo ngaphandle kwe-oxidation, i-rocks kunye neziphene ukuqinisekisa ukuba ayizukuvuza okanye yonakaliswe ngexesha lokufakwa kunye nokusetyenziswa.

Ngokubanzi, umgangatho we-ASTM a53 ungumgangatho obalulekileyo kwimibhobho yentsimbi yekhabhoni. Ibandakanya iimfuno zokwenziwa kweekhemikhali, iipropathi zoomatshini, ubukhulu kunye nomgangatho wokubonakala wemibhobho. Imibhobho eveliswe ngokwesiqhelo le nto inokuqinisekisa ukusebenza okuzinzileyo kunye nokusebenza okuthembekileyo, kwaye kufanelekile kwiinkqubo zemizi-mveliso nakwimimandla eyahlukeneyo yemizi mveliso. Ukuqulunqwa kunye nokuphunyezwa kweMigangatho ye-ASTM ye-A53 kubaluleke kakhulu ekuqinisekiseni ukusebenza ngokukhuselekileyo kwemibhobho kunye nokukhuthaza umgangatho wokwakha iprojekthi.
