Izindlela zokuqapha nokwamukela ukuthenga

Izinto zokusetshenziswa zamapayipi ensimbi ashiselwe yinsimbi evamile ephansi ye-carbon, insimbi ephansi ye-alloy noma insimbi ephezulu ye-manganese, njll., esetshenziswa kabanzi kuma-boilers, izimoto, imikhumbi, iminyango namafasitela esakhiwo sensimbi elula, ifenisha, imishini ehlukahlukene yezolimo, amashalofu akhuphukayo, iziqukathi, njll. Ngakho-ke yiziphi izinyathelo zokuphepha nokwamukelwa kokuthenga amapayipi ensimbi ashiselwe?

Izinyathelo zokuphepha zokuthenga amapayipi ensimbi ashiselwe:

1. Hlola izimfanelo zomkhiqizi, ukuthi ingabe ilayisense yebhizinisi, isitifiketi sekhodi yenhlangano, isitifiketi sokubhaliswa kwentela, ilayisense yokukhiqiza nokusebenza nezinye izinto zemfundo kuqediwe.
2. Bheka icala, hlola ukusebenza komphakeli, kanye nesimo samaphrojekthi asetshenziswa esikhathini esidlule.
3. Ingabe ikhona imikhumbi yezokuthutha ezakhelwe yona?Ukukhetha umhlinzeki wesevisi ngemikhumbi yezokuthutha ezakhiwe ngokwakho kunganciphisa izindleko zokuthutha, futhi into ebaluleke kakhulu ukuqinisekisa ukulethwa ngesikhathi.
4. Isevisi yangemuva kokuthengisa, kungakhathaliseki ukuthi kunohlelo oluzwakalayo noluthembekile lwesiqinisekiso sesevisi yangemuva kokuthengisa, kanye nezinkinga zekhwalithi ekwamukelweni kwezimpahla nasekusetshenzisweni okulandelayo kufanele zixazululwe ngesikhathi.

Indlela yokwamukela amapayipi ensimbi ashiselwe:

1. Hlola ukuthi izinto zokuqinisekisa ikhwalithi njengesitifiketi sekhwalithi yomkhiqizo, imanuwali yezinto ezibonakalayo, kanye nencwadi yokuqinisekisa ikhwalithi kuphelele.
2. Hlola ukubukeka kwepayipi elishiselwe, ingaphezulu libushelelezi futhi liyisicaba, i-weld seam iminyene ngaphandle kwama-burrs, akukho ukugqwala kwendawo yamafutha, akukho deformation ye-extrusion, futhi ingxenye yesiphambano iyisicaba.
3. Sebenzisa i-micrometer ukuze uhlole ukuthi ububanzi bangaphandle nokuqina kodonga lwepayipi elishiselwe kuyahlangabezana yini nezidingo, futhi ukuchezuka kokuqina kodonga olujwayelekile akudluli ku-3% -5%.
4. Sebenzisa umtshina onamaphutha ukuze uthole amaphutha angakonakali kumapayipi ashiselwe.
5. Yenza ukuhlolwa kwamandla okugoba okugobayo ngokwezidingo, goba ipayipi elishiselwe amadigri angama-30, futhi akukho mfantu ejikeni.
