Kwiminyaka yakutshanje, kubekho utshintsho olukhulu ekuqondeni kweshishini lesinyithi ngee-alloys zesinyithi sekhabhoni kunye nokumelana kwazo nokuqhekeka koxinzelelo lokugqwala. Olu tshintsho lubangele ukugxila ngokutsha kumgangatho kunye nemigangatho yepayipi yesinyithi, ngakumbi leyo yenziwe ngokweenkcazo ze-ASTM (American Society for Testing and Materials). Ipayipi yesinyithi sekhabhoni ibisoloko iqatshelwa ngokuqina kwayo kunye nokuthembeka kwayo, kwaye isiqinisekiso sayo samva nje somgangatho wamazwe ngamazwe siqinisa isikhundla sayo njengomgangatho weshishini.
Ngokwesiko, ezinye ii-alloy zentsimbi yekhabhoni ziye zathathwa njengezingamelani nokuqhekeka koxinzelelo, nto leyo eyenza ukuba zibe lukhetho oludumileyo kwiintlobo ngeentlobo zezicelo zoshishino. Nangona kunjalo, uphuhliso lwakutshanje lubonisa ukuba ezinye zezi alloy zinokuba sengozini yolu hlobo lokugqwala. Oku kufunyanisiweyo kubangele inkxalabo kushishino kwaye kwagxininisa ukubaluleka kwamanyathelo okulawula umgangatho ngokungqongqo kwimveliso yeepayipi zentsimbi.
Ukuphendula kwezi nkxalabo,Imibhobho yentsimbi yekhabhoni ye-ASTMabavelisi bathathe amanyathelo asebenzayo ukuqinisekisa umgangatho ophezulu kunye nemigangatho yokusebenza. Oku kuzibophelela ekugqweseni kufikelela kwisiqinisekiso somgangatho wamazwe ngamazwe, okubonisa ukuba ityhubhu yentsimbi iyahlangabezana neemfuno ezingqongqo ezibekwe yimigangatho yomgangatho wehlabathi. Le mpumelelo ayibonisi nje kuphela ukuzinikela kwabavelisi beepayipi zentsimbi ekugcineni amanqanaba omgangatho ophezulu, kodwa ikwamisela ipayipi yentsimbi ye-ASTM njengophawu lokuthembeka nokuqina kweshishini.
Isiqinisekiso somgangatho wehlabathi seepayipi zentsimbi zikaMs sibaluleke kakhulu kumashishini ahlukeneyo axhomekeke kwiipayipi zentsimbi ezikumgangatho ophezulu, kubandakanya ulwakhiwo, uphuhliso lweziseko kunye nokuveliswa kwemizi-mveliso. Ngokuhlangabezana nokugqitha imigangatho yomgangatho wehlabathi, iipayipi zentsimbi ze-ASTM zibonelela iinjineli, abakhi kunye nabaphathi beeprojekthi ngesiqinisekiso sokuba izicelo zabo zixhaswa zizixhobo ezihlala ixesha elide nezithembekileyo.
Ukongeza, ukufunyanwa kwesatifikethi somgangatho wamazwe ngamazwe kunyuse umgangatho weepayipi zentsimbi ze-ASTM ukuya kwimilinganiselo yoshishino. Njengemilinganiselo, iipayipi zentsimbi ze-ASTM zibeka umgangatho wokugqwesa kwabanye abavelisi, nto leyo eqhuba ukuphuculwa ngokubanzi komgangatho kunye nokusebenza kweepayipi zentsimbi kulo lonke ishishini. Oku akuvumeli kuphela abasebenzisi bokugqibela ukuba bakhethe ngokuzithemba.Imibhobho yentsimbi edibeneyokwiiprojekthi zabo, kodwa ikwakhuthaza ukhuphiswano olusempilweni kunye nobuchule kwishishini lokuvelisa intsimbi.
Uhambo lwe-ASTM steel pipe lokufumana isiqinisekiso somgangatho wamazwe ngamazwe lubungqina bokuzibophelela kweshishini ekuphuculeni okuqhubekayo kunye nokunamathela kwimigangatho yomgangatho ophezulu. Lugxininisa ukubaluleka kokuhambisana nophuhliso lwetekhnoloji kunye nokuphuhlisa rhoqo ukuqonda iipropati zezinto ezibonakalayo ukuqinisekisa ukuba i-steel pipe ihlala iphambili ekuthembekeni nasekusebenzeni.
Isishwankathelo,umbhobho ojikelezayo wentsimbi'sUkuphumelela kwesatifikethi somgangatho wamazwe ngamazwe kuphawula inyathelo elibalulekileyo kushishino lwentsimbi. Ayisombululi nje kuphela imingeni eguqukayo enxulumene nokuqhekeka koxinzelelo kodwa ikwayimbhobho yentsimbi engqukuva
umlinganiselo weshishini womgangatho kunye nokuthembeka. Njengoko imfuno yombhobho wentsimbi ohlala ixesha elide nosebenza kakuhle iqhubeka ikhula, isiqinisekiso somgangatho wehlabathi se-ASTM Steel Pipe siqinisa isikhundla sayo njengokhetho oluthembekileyo noluphambili kwiintlobo ngeentlobo zezicelo.
