I-ASTM A500 kunye ne-ASTM A501zombini ngokukodwa ukujongana neemfuno ezinxulumene nokwenziwa kombhobho wesakhiwo se-carbon steel.
Nangona kukho ukufana kwimiba ethile, zikwanazo neempawu zazo ezizodwa kunye nokusetyenziswa.
Okulandelayo siza kujonga umahluko ophambili phakathi kwe-ASTM A500 kunye ne-ASTM A501 kunye nendlela ezisetyenziswa ngayo kwizicelo ezahlukeneyo.
Iinkqubo Zokuvelisa
Iinkqubo zokwenziwa kwe-ASTM A500
Umbhobho we-ASTM A50 uya kwenziwa ngeenkqubo ezingenamthungo okanye ezidityanisiweyo.
I-Welded tubing iya kwenziwa kwi-flat-rolled steel ngenkqubo ye-electric-resistance-welding (ERW).
Iinkqubo zokwenziwa kwe-ASTM A501
Imibhobho iya kwenziwa ngenye yezi nkqubo zilandelayo: i-seamless, i-furnace butt welding (i-welding eqhubekayo);ukumelana nokuwelda okanye ukuwelda kwe-arc emanzini.
Iya kuthi ke iphinde ifudunyezwe kulo lonke icandelo elinqamlezileyo kunye ne-thermoformed ngokunciphisa okanye ukwenza iinkqubo, okanye zombini.
Ukubunjwa kokugqibela kobume kuya kwenziwa ngenkqubo yokubumba eshushu.
Iinkqubo ezahlukeneyo zokuVelisa
Yomibini imigangatho ivumela ukusetyenziswa kobuchule bokwenza imibhobho engenamthungo;
Ukuba inkqubo ye-welding isetyenziselwa ukuvelisa, i-ASTM A500 isebenzisa i-electric-resistance-welded (RW), ngelixa i-ASTM A501 ivumela iindlela ezahlukeneyo zokudibanisa, kubandakanywa umbane-ukuxhathisa-welding (RW), i-arc welding efakwe emanzini (SAW), njl.
Nangona kunjalo, i-ASTM A501 idinga ukuba umbhobho uphathwe ukushisa, okunceda ukuphucula ukufana kunye neempawu zemishini yezinto.Injongo ye-thermoforming kukuphucula izinto eziphathekayo ngokuphatha ukushisa umbhobho ngaphambi kokuba imilo yayo igqitywe.
I-ASTM A500 ayinazo iimfuno ezineenkcukacha ezinjalo.
Ukuhlelwa kwamaBanga
Uluhlu lobungakanani obusebenzayo
Amacandelo eMichiza
Kuthatyathwe kunye, kukho iiyantlukwano kwiintlobo zeekhemikhali ze-carbon steel structural tubes ezichazwe kwimigangatho emibini, i-ASTM A500 kunye ne-ASTM A501.
Kwi-ASTM A500, iBanga B kunye neBanga D zineemfuno ezifanayo zokwakheka kweekhemikhali, ngelixa iBakala C linomxholo wekhabhoni oncitshisiweyo onxulumene no-B no-D. Kwi-ASTM A501, ukwakheka kweekhemikhali zeBanga A kuyafana naleyo yeBanga B, ngelixa IBakala C linomxholo ocuthiweyo wekhabhoni xa kuthelekiswa neBakala B.
Kwi-ASTM A501, ukubunjwa kweekhemikhali zeBanga A kufana neBanga B kunye ne-D ye-A500, kodwa kwiBanga B kunye ne-C i-carbon content iyancitshiswa, umxholo we-manganese unyuswe kancinci, kwaye umxholo we-phosphorus kunye nesulfure ungaphantsi kwiBanga A.
Umxholo wobhedu uhlala usisiseko esifunekayo esingaguqukiyo kuwo onke amabakala.
Iimfuno ezahlukeneyo zokubunjwa kweekhemikhali zibonisa iimfuno ezithile zemigangatho emibini yeenkqubo ezahlukeneyo zokuvelisa kunye nezicelo, ukuqinisekisa ukuba izinto eziphathekayo zihlangabezana nemilinganiselo yokusebenza yoluhlu olubanzi lobunjineli kunye nezicelo zesakhiwo.
Ukusebenza koomatshini
I-ASTM A500 yokuSebenza koomatshini
I-ASTM A501 yokuSebenza koomatshini
IiPropati ezahlukeneyo zoomatshini
Izinto eziphathekayo kwi-A501 ngokuqhelekileyo zinika amanqanaba aphezulu amandla ngenxa yokonyuka kwamandla entsimbi ukusuka kwinkqubo yokubumba eshushu.
IiProjekthi zoMfuniselo
Iimfuno ezahlukeneyo zezinto zokulinga kwimigangatho emibini zibonisa iinkqubo zokuvelisa kunye nokusetyenziswa okujoliswe kuyo kwezi ityhubhu ezimbini ezahlukeneyo.
Umgangatho we-ASTM A500 udinga uHlalutyo lwe-Thermal, uHlahlelo lweMveliso, kunye neePropati zeMechanical ukongeza kuVavanyo lwe-Flattening, uvavanyo lwe-Flaring, kunye ne-Wedge Crush Tes ukuqinisekisa ukuba inkqubo yokubumba ebandayo ayichaphazeli kakubi izinto eziphathekayo.
Umgangatho we-ASTM A501 ugxininisa inkqubo ye-thermoforming, kwaye ekubeni iimveliso ze-thermoformed sele ziphathwe ubushushu ngexesha lenkqubo yokuvelisa, ezi mvavanyo zingathathwa njengezingafunekiyo ngenxa yokuba unyango lobushushu sele luqinisekisile iplastiki kunye nokuqina kwezinto.
Iindawo zosetyenziso
Nangona zombini zidlala indima yolwakhiwo, ugxininiso luya kwahluka.
Ityhubhu ye-ASTM A500 isetyenziswa kakhulu kwizakhiwo zokwakha, ukwenziwa koomatshini, iifreyimu zezithuthi, kunye nezixhobo zezolimo ngenxa yokugoba kwayo okuhle okubandayo kunye neempawu zokuwelda.
Ishubhu ye-ASTM A501 ifaneleke ngakumbi kwizicelo zokwakha kunye nezakhiwo ezifuna amandla aphezulu kunye nokuqina, njengokwakhiwa kwebhulorho kunye nezakhiwo ezinkulu zenkxaso, ngenxa yokuqina kwayo okugqwesileyo kunye namandla.
Yomibini imigangatho inika isikhokelo sokwenza i-carbon steel tubing esemgangathweni ophezulu, kodwa ukhetho olungcono luxhomekeke kwiimfuno kunye nemiqobo yeprojekthi ethile.
Ukuba ulwakhiwo lufuna ukusebenza kakuhle kwindawo yobushushu obuphantsi, i-ASTM A501 inokukhethwa ngenxa yokuba ukonyuka kokuqina ukusuka ekubunjweni okutshisayo kunika ukuchasana ngcono kwi-brittle fracture.Ngakolunye uhlangothi, ukuba ulwakhiwo luzakwakhelwa indawo yangaphakathi, i-ASTM A500 inokwanela, njengoko inokubonelela ngamandla afunekayo kunye nokusebenza, ngelixa inokuba neendleko ezincinci.
