Eminyakeni yamuva nje, kube noshintsho olukhulu ekuqondeni kwemboni yensimbi ama-alloys ensimbi ye-carbon kanye nokumelana kwawo nokucindezeleka kokuqhekeka kokugqwala. Lolu shintsho lugqugquzele ukugxila okuvuselelwe kwikhwalithi namazinga wepayipi lensimbi, ikakhulukazi lawo akhiqizwa ku-ASTM (American Society for Testing and Materials) imininingwane. Ipayipi lensimbi ye-Carbon kudala laqashelwa ukuqina nokuthembeka kwalo, futhi isitifiketi salo sakamuva sekhwalithi yamazwe ngamazwe siqinisa isikhundla salo njengophawu lwembonini.
Ngokwesiko, ama-alloys athile e-carbon steel athathwe njengokumelana nokucindezeleka kokuqhekeka kokugqwala, okuwenza abe yinketho edumile yezinhlelo zokusebenza ezihlukene zezimboni. Kodwa-ke, intuthuko yakamuva iphakamisa ukuthi amanye alawa ma-alloys angase abe lula kulolu hlobo lokugqwala. Ukutholwa kwabangela ukukhathazeka ngaphakathi embonini futhi kwagqamisa ukubaluleka kwezinyathelo eziqinile zokulawula izinga ekukhiqizeni amapayipi ensimbi.
Ukuphendula lezi zinkinga,I-ASTM carbon steel amapayipiabakhiqizi bathathe izinyathelo ezisheshayo zokuqinisekisa ikhwalithi ephezulu kanye namazinga okusebenza. Lokhu kuzibophezela ekwenzeni okuhle kufinyelela umvuthwandaba ngesitifiketi sekhwalithi samazwe ngamazwe, okubonisa ukuthi ishubhu lensimbi lihlangabezana nezidingo eziqinile ezibekwe izindinganiso zekhwalithi zomhlaba wonke. Le mpumelelo ayibonisi nje kuphela ukuzinikela kwabakhiqizi bamapayipi ensimbi ekugcineni amazinga aphezulu ekhwalithi, kodwa futhi isungula ipayipi lensimbi ye-ASTM njengophawu lwemboni lokwethembeka nokuhlala isikhathi eside.
Ukuqinisekiswa kwekhwalithi yamazwe ngamazwe kwamapayipi ensimbi kubaluleke kakhulu ezimbonini ezihlukahlukene ezithembele emapayipini ensimbi ekhwalithi ephezulu, okuhlanganisa ukwakhiwa, ukuthuthukiswa kwengqalasizinda kanye nokukhiqizwa kwezimboni. Ngokuhlangabezana nokweqa amazinga ekhwalithi yamazwe ngamazwe, ipayipi lensimbi le-ASTM linikeza onjiniyela, osonkontileka nabaphathi bephrojekthi isiqinisekiso sokuthi izicelo zabo zisekelwa izinto ezihlala isikhathi eside nezithembekile.
Ngaphezu kwalokho, ukutholwa kwesitifiketi sekhwalithi samazwe ngamazwe kukhuphule izinga lamapayipi ensimbi e-ASTM ukuze kube nezilinganiso zemboni. Njengesilinganiso, ipayipi lensimbi le-ASTM libeka izinga eliphezulu ukuze abanye abakhiqizi balilandele, liqhuba ukuthuthukiswa okuphelele kwekhwalithi nokusebenza kwepayipi lensimbi kuyo yonke imboni. Lokhu akuvumeli kuphela abasebenzisi bokugcina ukuthi bakhethe ngokuzethembaamapayipi ensimbi ashiselwengamaphrojekthi abo, kodwa futhi ikhuthaza ukuncintisana okunempilo kanye nokusungula embonini yokukhiqiza insimbi.
Uhambo lwamapayipi ensimbi e-ASTM lokuthola isitifiketi sekhwalithi yamazwe ngamazwe luwubufakazi bokuzibophezela kwemboni ekwenzeni ngcono okuqhubekayo nokubambelela emazingeni aphezulu kakhulu. Igqamisa ukubaluleka kokuhambisana nentuthuko yezobuchwepheshe kanye nokuthuthukisa ngokuqhubekayo ukuqonda kwezakhiwo zempahla ukuze kuqinisekiswe ukuthi ipayipi lensimbi lihlala lihamba phambili ekuthembekeni nasekusebenzeni.
Ngokufigqiwe,ipayipi eliyindilinga lensimbi'sukuzuzwa kwesitifiketi sekhwalithi yamazwe ngamazwe kuphawula ingqophamlando ebalulekile embonini yensimbi. Ayixazululi kuphela izinselele eziguqukayo ezihlobene nokuqhekeka kokugqwala kwengcindezi kodwa futhi yenza ipayipi lensimbi eliyindilinga
ibhentshimakhi yemboni yekhwalithi nokuthembeka. Njengoba isidingo sepayipi lensimbi elihlala isikhathi eside nelisebenza kakhulu liqhubeka nokukhula, isitifiketi sekhwalithi yamazwe ngamazwe se-ASTM Steel Pipe siqinisa isikhundla saso njengenketho ethenjwayo neyokuqala yezinhlelo eziningi zokusebenza.
