ASTM A106 uyihlobo olukhethwe kwisezantsi lokusemthethweni esandleni sokuqinisekisa amagcali yasekhombisi ezifanayo. Kufuneka uhlale ukwazi le ndawo ngeemgceni, okuningi lapho uzokwazi ukukhetha igcino elungileyo lesi-steel leshiswe kulesi simela sakho. Ukukhanya ngokuphakamisayo kuyaboza ukukhetha izinkinga ezibonakalayo.
Yilokhu olungaphezulu lolu hlobo oluhlukele kuyo ASTM A106. Uya kubizwa njenge carbon steel elithi black-, iron- noma heat-treated carbon-grade steel elingezansi kwe-0% kunye ne-% kunye ne-/2"(1mm) ku-NC (Billet Size). Yilencinci lesi carbon steel futhi lokuthi ngokwesiphi siyayiphi inani lemfumo wakhe. I-ASTM A106 esi carbon steel sikhona umoya ophambili nokuhlala kususelwe ngendlela enkulu. Ngokulandelana nesi sicwangciso, sivumela ukusetshenziswa njengemigca yezilindi zomoya omncane okanye amasimu asempahla apho amafuthi akhona ngendlela engcono. Lokhu kungaba ubuncinci obungakwazi ukuba beselelwa kwindawo eziningi.
I ASTM A106 ithophu yiyo emibuzweni yayo eziningi. Amagreyde amaningi amaphakathi kwezinye izilungiselelo; ngokulandelana nesicwangciso sikhemi ngokwesigaba, amanqaku angazange akuyinkqubo ngokubanzi kanye nokuncane kusenzo sokushesha. Igrade B iyazinga lokulandelayo lasezigaba ezininzi kunye nokuba kukhona kuhlu kanye nokuhlola kakhulu.
Kunye namanje amandla amahlukene okufanele abe ngokwesigaba sase ASTM A106 esifumanisa isicwangciso sikhemi kunye nezilungiselelo zesithelo sesiqephu. Zonke ilinganekwazi kanye nemidiamitha ayizange azibekwe ngokubalulekile.
Umgeweko we-A: Usobizo lwesikhephe siza kuhlala ngokwesifazane (1) kuphela & umkhakha wocarbong ngenqanawe yezinye zintathu% \/5ATERIALOFGALVANIZED IRON PIPE [KWAMASHONISWA KUMSHINI WOKUSUSA] Kufanele kunyuzwe kumsebenzi ejwayelekileyo apho akukho okungaphezulu ukusetyenziswa kwesikhephe.
Usobizo lwe-B: Usobizo lwe-Grade B luhlukeneyo kakhulu kwiisikhephe somabhi yesitsha ama-B. Kuna umkhakha wocarbong ezintathu zine% nelesobizo olunene lokuthi amandla nokushota kakhulu kuyafumaneka ngemibono eyahlukene ekugcineni, okuningi lokulandelana nokusebenza kakhulu kwiindawo eziningi, ukuze i-ANSI \/ ASME B16 GR:F60 Slipon Flanges ifanele kubanzi kakhulu kusebenza kwindawo ezininzi zokusebenza.
Ngakwesoku, uma kufuneka usebenze nge-ASTM A106 steel ngaphandle kancane - akukho nto okungcono yokudinga ukubaleka ngesithetho esikhona abantu ababekho ababizwa bantfu. Bayazi ukuba bayahlelisa ukhethelela isikhephe esethathweni sesobizo sako ngokusebenzisa.
Kune timbili lethekwani lethandwa kakhulu lwe ASTM A106 nesiphatha sokugcina amaqote, amaphrofeshoni amaningi kanye nokusebenza ngokukhonzwa. Naloo timbili lethekwani lethe sengxenyeni lokusetyenziswa lokungabizwa 24 izinsuku zomusha ukuthola amahlawulwane, amaxwebhu, amasoloshini kunye nemibuzo ezifanayo. Siyiqinisekisi elilindelela lokuthi sizohlala ngokuphathelene nawe
Siyafundisa ngezinye iindlela ezikhulu zokuthenga amagwala, futhi wonke amanqaku apho aqhunywe ngaphambi kokuthumela, umthakathi uguqukileyo. Imanqaku emkhulu yonke ilandelwe ngamandla okanye amagwala (ERW/SSAW/LSAW/ galvanized/astm a106/seamless pipe/stainless steel pipe), amaprola (American standard, British standard, Australian standard H-beam steel), amabhele, Angle steel, flat steel, steel sheet piles, izigaba zonke ezidinga amagwala nezi coil, strip steel, scaffolding, steel wire, nails, netshengene.
Kwethu kwiNgcwadi engu-17 emasendle yenkululeko yokuthenga amagwala nokufakwa komsebenzi omphambili wamanqaku nemibhulukweni. Ngokugcina, sithi sihlola imiphumela ka-astm a106, ukubaluleka kwesicelo esisodwa, futhi sizothatha isenzo sezikhona kakhulu kunye nomphathiso. Ukuthi lokhu olungemali olushesha kuzo luchasene nolunye ulwandle!
Siyakwamukela amasiphi esendaweni se-Amerika/Britain/Australia H-beams i-Japanese standard steel astm a106 noma ukufakwa kwezinye izinhlelo zokuphatha ngokugcina nokusuka. Ngokuqondile, izilungiselelo zethu zibe ekuthathweni le-Ngutshini Europe, Oseania, South America, Southeast Asia, Afrika, Middle East kunye nema-region eziyinani lokho.
