2. Ngaba i-ASTM A276 kunye ne-ASTM A479 zinokugubungela umgangatho ofanayo wentsimbi engagqwaliyo?

Ewe, amanqaku amaninzi angafumaneka phantsi kwemigangatho yomibini, efana ne-304, 316, 316L, 321 kunye nezinye iimpawu zentsimbi engagqwaliyo. Nangona kunjalo, umthengi kufuneka aqinisekise ukuba iprojekthi ifuna i-A276, A479 okanye i-ASME SA479 ngokukodwa.

3. Ngowuphi umgangatho ofanele usetyenziswe kwi-stainless steel round bar?

Kwibha ejikelezileyo yentsimbi engagqwali esetyenziswa kwimishini, kwiishafti, kwiintonga nakwii-fasteners, i-ASTM A276 isetyenziswa rhoqo. Kwibhari ezenzelwe izitya zoxinzelelo, iibhoyila, iivalvu, iimpompo okanye izixhobo zoxinzelelo, i-ASTM A479 okanye i-ASME SA479 ingangcono.

4. Ingaba i-ASTM A479 ibiza kakhulu kune-ASTM A276?

Ixabiso lixhomekeke kudidi, ububanzi, imeko, uhlolo, ubungakanani kunye neemfuno zamaxwebhu. Iiprojekthi ze-ASTM A479 zinokufuna amaxwebhu angqongqo okanye uhlolo olongezelelweyo, olunokuchaphazela iindleko. Nangona kunjalo, udidi lwezinto kunye nobubanzi bovavanyo zihlala zinempembelelo enkulu kwixabiso kunenani eliqhelekileyo lodwa.

5. Sisiphi isatifiketi ekufuneka abathengi basicele?

Abathengi kufuneka bacele i-EN 10204 3.1 MTC ebonisa umgangatho we-ASTM, ibakala, inombolo ye-UNS, inombolo yobushushu, ulwakhiwo lweekhemikhali, iimpawu zoomatshini, ubungakanani, imeko yonyango lobushushu kunye neziphumo zokuhlolwa. Uvavanyo lwe-PMI, uvavanyo lwe-UT, uvavanyo lobunzima kunye nokuhlolwa komntu wesithathu nako kunokucelwa kwiiodolo ezibalulekileyo.

6. Ngaba i-ASTM A276 ingasetyenziswa endaweni ye-ASTM A479?

Kuphela xa umnini weprojekthi, injineli okanye umthengi evuma utshintsho. Ukuba iinkcukacha zokuthenga okanye umzobo ufuna i-ASTM A479 okanye i-ASME SA479, i-ASTM A276 akufuneki itshintshwe ngaphandle kwemvume ebhaliweyo, ingakumbi kwiiprojekthi ezinxulumene noxinzelelo.

7. Loluphi ulwazi olufunekayo ukuze ufumane isicatshulwa esikhawulezileyo?

I-RFQ epheleleyo kufuneka iquke umgangatho we-ASTM, ibakala, inombolo ye-UNS, imilo yebha, ububanzi okanye ubungakanani, ubude, ubungakanani, ukugqitywa komphezulu, ukunyamezela, imeko yonyango lobushushu, imfuneko yovavanyo, imfuneko ye-MTC, izibuko lendawo ekuyiwa kuyo kunye nemfuneko yokupakisha. Umzekelo: Ibha engqukuva yentsimbi engagqwaliyo ye-ASTM A479 UNS S31603 316L, ububanzi obuyi-40 mm, ubude obuyi-3000 mm, umphezulu oxotyulweyo, uvavanyo lwe-EN 10204 3.1 MTC kunye ne-PMI.

Isiphelo

I-ASTM A276 kunye ne-ASTM A479 zombini ziyimigangatho ebalulekileyo yebha yentsimbi engagqwali, kodwa zisetyenziselwa iimeko ezahlukeneyo zokusetyenziswa. I-ASTM A276 isetyenziswa kakhulu kwiibha zentsimbi engagqwali kunye neemilo, ngelixa i-ASTM A479 ifuneka kakhulu kwiibha ezisetyenziswa kwiibhoyila, kwimikhumbi yoxinzelelo kunye nezixhobo ezinxulumene noxinzelelo. Ukhetho oluchanekileyo luxhomekeke kwisicelo sokugqibela, imfuneko yomzobo, ikhowudi yeprojekthi kunye nemfuneko yesatifikethi.

Ukuze abathengi baphumelele ekuthengeni, kufuneka baqinisekise umgangatho we-ASTM, umgangatho wentsimbi engatyiwayo, inombolo ye-UNS, uhlobo lwebha, ubungakanani, ukugqitywa komphezulu, imeko yonyango lobushushu, i-EN 10204 3.1 MTC, ulawulo lwenombolo yobushushu, uvavanyo lwe-PMI, uvavanyo lwe-UT, ukuhlolwa kobukhulu kunye nokupakishwa kokuthumela ngaphandle. Umthengisi wensimbi engatyiwayo oqeqeshiweyo kufuneka ancede abathengi bakhethe umgangatho ochanekileyo kunye nomgangatho ngokuhambelana nokumelana nokugqwala, amandla, inkonzo yoxinzelelo, iindleko kunye neemfuno zokuhambisa.

Cela iNtetho

Nxibelelana nathi ukuze ufumane iikowuteshini, uvavanyo lwe-MTC, i-PMI, ubungakanani obulungiselelwe wena, ukugqitywa komphezulu, ukupakishwa kokuthumela ngaphandle kunye nenkxaso yokuhanjiswa.
