9711.1 Ipayipi Lensimbi Elivundlile

Incazelo emfushane:

Eyaziwa nangokuthi i-spiral barrel noma i-spiral body. Ububanzi bangaphandle beshubhu elivunguzayo cishe bangama-nanometer angu-30, ububanzi bangaphakathi bucishe bube ngama-nanometer angu-10, kanti ibanga eliphakathi kwama-spiral aseduze lingaba ama-nanometer angu-11. I-spiral tube izungezwe ama-nucleosomes angu-6 njalo ngesonto. Ama-histones e-H1 atholakala endaweni engaphakathi ye-lumen ye-spiral tube futhi adlala indima ebalulekile ekugcineni ukwakheka kweshubhu elizungezayo. Imicu ye-nanometer engu-10 eyakhiwe ama-nucleosome ijikijelwa ibe imicu engu-30 ewugqinsi, ecindezela ngokwengeziwe ubude be-DNA izikhathi ezingu-6.

Isibonisi somkhiqizo

Ishubhu yezimboni

Amapayipi okuvunguza asetshenziswa kakhulu kumapayipi kawoyela nawegesi yemvelo, futhi ukucaciswa kwawo kuvezwa ubukhulu bangaphandle * bodonga. Amapayipi okuvunguza angashiselwa ohlangothini olulodwa noma ezinhlangothini zombili. Ipayipi elishiselwe kufanele liqinisekise ukuthi ukuhlolwa komfutho wamanzi, amandla aqinile we-weld nokusebenza kokugoba okubandayo kuhlangabezana nezidingo.

Indlela yokwelapha ebusweni:
1. Ukuhlanza
Ama-solvents nama-emulsions asetshenziselwa ukuhlanza ubuso bensimbi ukususa amafutha, amafutha, uthuli, i-ejenti yokushelela kanye ne-organic matter efanayo, kodwa ayikwazi ukususa ukugqwala, isikali se-oxide, i-welding flux, njll ebusweni bensimbi, ngakho-ke kuphela. esetshenziswa njengesinyathelo esisizayo ekukhiqizeni okulwa nokugqwala.

2. Amathuluzi okukhipha ukugqwala
Okokuqala, sebenzisa amabhulashi ocingo namanye amathuluzi ukuze upholise ubuso bensimbi, okungasusa isikali se-oxide esixekethile noma esonakele, ukugqwala, i-welding slag, njll. Ukususwa kokugqwala kwamathuluzi esandla kungafinyelela izinga le-Sa2, futhi amathuluzi amandla angafinyelela. izinga le-Sa3.

3. Ukukha
Ngokuvamile, izindlela ezimbili zamakhemikhali kanye ne-electrolysis zisetshenziselwa ukuqoqa. I-anticorrosion yepayipi isebenzisa kuphela ukukha ngamakhemikhali, okungasusa isikali se-oxide, ukugqwala, nezindwangu ezindala. Kwesinye isikhathi ingasetshenziswa njenge-sandblasting kanye nokususwa kokugqwala. Ukuhlanzwa kwamakhemikhali ngokuqinisekile kungenza ukubukeka kufinyelele izinga elithile lokuhlanzeka kanye nokuqina, kodwa iphethini yayo yehange ayijulile, futhi kulula ukungcolisa isimo.

4. Ukufafaza (ukuphonsa) ukususa ukugqwala
Ukufafaza (ukuphonsa) ukususwa kokugqwala kuyinjini enamandla amakhulu eshayela izindwani zokufafaza (ukuphonsa) ukuze zijikeleze ngesivinini esikhulu, ukuze insimbi yensimbi, isibhamu sensimbi, ingxenye yocingo lwensimbi, amaminerali nezinye iziqhumane zifuthwe (ziphonswe) ubuso bepayipi lensimbi ngaphansi komphumela wamandla we-centrifugal. , Akukhona nje kuphela okungakwazi ukuqeda ngokuphelele ukugqwala, ama-oxides nokungcola, kodwa futhi ipayipi yensimbi ingafinyelela ukulingana okulinganiselwe okudingekayo ngaphansi komphumela womthelela oqinile kanye nokungqubuzana kwe-abrasive.
Ngemva kokufafaza (ukuphonsa) ukuze kukhishwe ukugqwala, akukhona nje kuphela ukuthi umphumela wokukhangiswa ngokomzimba kwendawo yepayipi unganwetshwa, kodwa futhi nomphumela wokunamathela ngomshini wengqimba elwa nokugqwala kanye nendawo yepayipi ingaqiniswa. Ngakho-ke, ukususa ukugqwala kokufutha kuyindlela efanelekile yokukhipha ukugqwala kwepayipi lokuqeda ukugqwala. Ngokuvamile, ukususwa kokugqwala okudutshuliwe (isihlabathi) kusetshenziswa ikakhulukazi ukwelashwa kwangaphakathi nangaphandle kwepayipi, futhi ukukhishwa kokuqhuma kwesihlabathi (isihlabathi) kusetshenziswa kakhulu ukwelapha ipayipi.

Ukusetshenziswa okujwayelekile kwepayipi lensimbi elivunguzayo

Ipayipi lensimbi elivunguzayo likazwelonke elijwayelekile libizwa ngokuthi ipayipi lensimbi engu-9711.1, ipayipi lensimbi engu-9711.2, ukuhlukaniswa kwezinto ezibonakalayo: 16Mn ipayipi lensimbi elivunguzayo, ipayipi lensimbi elivunguzayo le-Q345B, ipayipi lensimbi elivunguzayo L245, ipayipi lensimbi eli-L360, ipayipi lensimbi elivunguzayo le-X40-X80, inhloso, Kuvunguza ipayipi lensimbi yokuhlanza indle, ukuhlanzwa kwamanzi Insimbi ye-Spiral amapayipi, amapayipi ensimbi asondekile ezimbonini zamanzi, amapayipi ensimbi asondekile amabhizinisi amakhemikhali emishini yokuphehla amandla, amapayipi ensimbi avunguzayo wamandla enuzi, amapayipi ensimbi asondekile okudlulisa uketshezi oluvutha umlilo, amapayipi ensimbi ayi-spiral okudlulisa uketshezi olungashi, amapayipi ensimbi ajwayelekile kazwelonke, kanye Ipayipi Lensimbi Elivunguzayo le-Ministry of Petroleum SY/T5037. Lo mkhiqizo usebenzisa i-hot-rolled steel strip njengempahla eluhlaza, yakhiwe ukuvunguza okujwayelekile okufudumele, futhi ishiselwe inqubo yokushisela ye-arc engaphansi kwamanzi. Umkhiqizo usebenzisa amazinga e-API SPEC 5L, EN10217, GB/T9711.1, GB/T9711.2. Isetshenziswa kakhulu embonini kawoyela negesi yemvelo ukuthutha uketshezi oluvuthayo noketshezi olungashi kanye nezakhiwo zensimbi.
