Ngakho-ke, umehluko muni? I-Open slab: Ipuleti eliyisicaba elitholakala ngokuvula ama-coil ensimbi, ...Funda kabanzi -
Uyini umehluko phakathi kwe-SECC ne-SGCC?
I-SECC ibhekisela eshidini lensimbi eliqiniswe ngogesi. Isijobelelo esithi “CC” ku-SECC, njengezinto eziyisisekelo i-SPCC (ishidi lensimbi eliqinisiwe elibandayo) ngaphambi kokufakwa ngogesi, sibonisa ukuthi liyizinto ezijwayelekile eziqinisiwe ezibandayo. Lisebenza kahle kakhulu. Ngaphezu kwalokho, ngenxa...Funda kabanzi -
Umehluko Phakathi kwe-SPCC ne-Q235
I-SPCC ibhekisela kumashidi nemigqa yensimbi yekhabhoni egoqwe ngokubandayo esetshenziswa kakhulu, okulingana nebanga le-Q195-235A laseShayina. I-SPCC inendawo ebushelelezi, ejabulisa ngobuhle, okuqukethwe okuphansi kwekhabhoni, izakhiwo ezinhle kakhulu zokunwebeka, kanye nokushibilika okuhle. Ikhabhoni evamile ye-Q235 ...Funda kabanzi -
Umehluko Phakathi Kwepayipi Nepayipi
Kuyini ipayipi? Ipayipi liyisigaba esingenalutho esinesigaba esiyindilinga sokuhambisa imikhiqizo, okuhlanganisa uketshezi, igesi, ama-pellet kanye nophuphu, njll. Ubukhulu obubaluleke kakhulu bepayipi ububanzi bangaphandle (OD) kanye nobukhulu bodonga (WT). I-OD minus izikhathi ezi-2 ...Funda kabanzi -
Iyini i-API 5L?
I-API 5L ngokuvamile ibhekisela endinganisweni yokusebenzisa yamapayipi ensimbi yamapayipi, ahlanganisa izigaba ezimbili eziyinhloko: amapayipi ensimbi angenamthungo namapayipi ensimbi ahlanganisiwe. Njengamanje, izinhlobo zamapayipi ensimbi ahlanganisiwe asetshenziswa kakhulu emapayipini kawoyela amapayipi ahlanganisiwe e-spiral ac ...Funda kabanzi -

Amapayipi ensimbi ahlukaniswa ngesimo esinqamulelayo abe amapayipi ayindilinga, ayisikwele, angunxande, nanobunjwa obukhethekile; ngezinto ezifakwa kumapayipi ensimbi esakhiwe ngekhabhoni, amapayipi ensimbi esakhiwe nge-alloy ephansi, amapayipi ensimbi ahlanganisiwe, namapayipi ahlanganisiwe; kanye nokusetshenziswa kumapayipi...Funda kabanzi -
Ungawashisela kanjani amapayipi e-galvanized? Yiziphi izinyathelo zokuphepha okufanele zithathwe?
Izinyathelo zokuqinisekisa ikhwalithi yokushisela zifaka: 1. Izici zabantu ziyisici esiyinhloko sokulawula ukushisela amapayipi agqitshiwe. Ngenxa yokuntuleka kwezindlela zokulawula ezidingekayo ngemuva kokushisela, kulula ukusika amakhona, okuthinta ikhwalithi; ngesikhathi esifanayo, uhlobo olukhethekile lwe-galva...Funda kabanzi -
Iyini insimbi egayiwe? Ihlala isikhathi esingakanani i-zinc coating?
Ukuhlanganisa i-galvanizing inqubo lapho kufakwa khona ungqimba oluncane lwensimbi yesibili ebusweni bensimbi ekhona. Ezindaweni eziningi zensimbi, i-zinc iyinto esetshenziswa kakhulu kulokhu kuhlanganiswa. Lolu ngqimba lwe-zinc lusebenza njengesivikelo, luvikela insimbi engaphansi ezintweni.Funda kabanzi -
Uyini umehluko phakathi kwamapayipi ensimbi agqitshwe nge-galvanized kanye namapayipi ensimbi engagqwali?
Umehluko obalulekile: Amapayipi ensimbi ahlanganisiwe enziwe ngensimbi yekhabhoni enoqweqwe lwezinki phezu komhlaba ukuze kuhlangatshezwane nezidingo zokusetshenziswa kwansuku zonke. Amapayipi ensimbi engagqwali, ngakolunye uhlangothi, enziwe ngensimbi ye-alloy futhi anokumelana nokugqwala ngokwemvelo, okususa...Funda kabanzi -
Ingabe insimbi egayiwe iyagqwala? Kungavinjelwa kanjani lokhu?
Uma izinto zensimbi ezihlanganisiwe zidinga ukugcinwa nokuthuthwa eduze, kufanele kuthathwe izinyathelo ezanele zokuvimbela ukugqwala. Izindlela zokuvimbela ezithile yilezi ezilandelayo: 1. Izindlela zokwelapha ubuso zingasetshenziswa ukunciphisa ifomethi...Funda kabanzi -
