9711.1 Ipayipi Lensimbi Ejikelezayo

Isithombe Esivelele Sepayipi Lensimbi Ejikelezayo engu-9711.1

Incazelo emfushane:

Yaziwa nangokuthi i-spiral barrel noma umzimba ojikelezayo. Ububanzi bangaphandle be-spiral tube bungama-nanometer angaba ngu-30, ububanzi bangaphakathi bungama-nanometer angaba ngu-10, kanti ibanga eliphakathi kwe-spiral eziseduze lingama-nanometer angaba ngu-11. I-spiral tube izungezwe ama-nucleosome angu-6 njalo ngeviki. Ama-histone e-H1 atholakala ebusweni bangaphakathi be-spiral tube lumen futhi adlala indima ebalulekile ekugcineni isakhiwo se-spiral tube. Ama-fibre angu-10 nanometer akhiwe ama-nucleosome ajikeleziswa abe ama-fibre angu-30 nanometer obukhulu, okucindezela ubude be-DNA izikhathi ezingu-6.

Ukuboniswa Komkhiqizo

Ipayipi lezimboni

Amapayipi ajikelezayo asetshenziswa kakhulu kumapayipi kawoyela negesi yemvelo, futhi imininingwane yawo ivezwa ubukhulu bodonga obungaphandle * ububanzi. Amapayipi ajikelezayo angashintshwa ohlangothini olulodwa noma zombili izinhlangothi. Ipayipi elihlanganisiwe kufanele liqinisekise ukuthi ukuhlolwa kwengcindezi yamanzi, amandla okunamathela kwe-weld kanye nokusebenza kokugoba okubandayo kuyahlangabezana nezidingo.

Indlela yokwelapha ubuso:
1. Ukuhlanza
Izinyibilikisi kanye nama-emulsion asetshenziselwa ukuhlanza ubuso bensimbi ukuze kususwe uwoyela, amafutha, uthuli, i-smoothing agent kanye nezinto eziphilayo ezifanayo, kodwa ayikwazi ukususa ukugqwala, isikali se-oxide, i-welding flux, njll. ebusweni bensimbi, ngakho-ke isetshenziswa kuphela njengesilinganiso esisizayo ekukhiqizeni okulwa nokugqwala.

2. Amathuluzi okususa ukugqwala
Okokuqala, sebenzisa amabhulashi ensimbi namanye amathuluzi ukupholisha ubuso bensimbi, okungasusa isikali se-oxide esixegayo noma esigobile, ukugqwala, i-welding slag, njll. Ukususwa kokugqwala kwamathuluzi esandla kungafinyelela ezingeni le-Sa2, kanti amathuluzi kagesi angafinyelela ezingeni le-Sa3.

3. Ukukha amanzi
Ngokuvamile, kusetshenziswa izindlela ezimbili zamakhemikhali kanye ne-electrolysis ekuqoqeni. Ukuvimbela ukugqwala kwamapayipi kusebenzisa kuphela ukuqoqa kwamakhemikhali, okungasusa isikali se-oxide, ukugqwala, kanye nokumbozwa okudala. Ngezinye izikhathi kungasetshenziswa njengokuqhuma kwesihlabathi kanye nokususa ukugqwala. Ukuhlanza kwamakhemikhali kungenza ukubukeka kufinyelele izinga elithile lokuhlanzeka kanye nobunzima, kodwa iphethini yayo ye-anchor ayijulile, futhi kulula ukungcolisa isimo.

4. Ukufutha (ukuphonsa) ukususa ukugqwala
Ukususa ukugqwala ngokufafaza (ukuphonsa) yinjini enamandla amakhulu eqhuba ama-blade okufafaza (ukuphonsa) ukuze ajikeleze ngesivinini esikhulu, ukuze i-grit yensimbi, i-steel shot, ingxenye yocingo lwensimbi, amaminerali kanye nezinye izinto ezisusa ukungcola kufefwe (kuphonswe) ebusweni bepayipi lensimbi ngaphansi komphumela wamandla e-centrifugal. , Akugcini nje ngokuqeda ngokuphelele ukugqwala, ama-oxide kanye nokungcola, kodwa futhi ipayipi lensimbi lingafinyelela isilinganiso esidingekayo sobukhali ngaphansi komphumela womthelela onamandla kanye nokungqubuzana kwe-abrasive.
Ngemva kokufutha (ukuphonsa) ukuze kususwe ukugqwala, akugcini nje ngokwandisa umphumela wokumuncwa ngokomzimba wobuso bepayipi, kodwa futhi nomphumela wokunamathela ngomshini wesendlalelo sokulwa nokugqwala kanye nobuso bepayipi ungaqiniswa. Ngakho-ke, ukususa ukugqwala ngokufutha kuyindlela efanele yokususa ukugqwala yokuvimbela ukugqwala kwepayipi. Ngokuvamile, ukususa ukugqwala ngokuqhumisa (isihlabathi) kusetshenziselwa kakhulu ukwelashwa kwangaphakathi nangaphandle kwepayipi, kanti ukususa ukugqwala ngokuqhumisa (isihlabathi) kusetshenziselwa kakhulu ukwelashwa kwangaphandle kwepayipi.

Ukusetshenziswa kwezinto zepayipi lensimbi elijikelezayo elijwayelekile likazwelonke

Ipayipi lensimbi elijwayelekile likazwelonke elijikelezayo libizwa ngokuthi ipayipi lensimbi elijikelezayo elingu-9711.1, ipayipi lensimbi elijikelezayo elingu-9711.2, ukuhlukaniswa kwezinto: Ipayipi lensimbi elijikelezayo elingu-16Mn, ipayipi lensimbi elijikelezayo le-Q345B, ipayipi lensimbi elijikelezayo le-L245, ipayipi lensimbi elijikelezayo le-L360, ipayipi lensimbi elijikelezayo le-X40-X80, injongo eyinhloko, ipayipi lensimbi elijikelezayo lokwelapha indle, ukuhlanzwa kwamanzi Amapayipi ensimbi ajikelezayo, amapayipi ensimbi ajikelezayo ezitshalweni zamanzi, amapayipi ensimbi ajikelezayo ezinkampani zamakhemikhali zezitshalo zamandla, amapayipi ensimbi ajikelezayo amandla enuzi, amapayipi ensimbi ajikelezayo okuhambisa uketshezi oluvuthayo, amapayipi ensimbi ajikelezayo okuhambisa uketshezi olungashi, amapayipi ensimbi ajwayelekile kazwelonke ajikelezayo, kanye nepayipi lensimbi elijikelezayo le-Ministry of Petroleum elijwayelekile le-SY/T5037. Lo mkhiqizo usebenzisa umucu wensimbi ogoqekile oshisayo njengezinto zokusetshenziswa, wakhiwa ngokwakhiwa okufudumele okujwayelekile, futhi ushiselwe ngenqubo yokushisela ye-arc engaphansi kwamanzi ezenzakalelayo. Umkhiqizo usebenzisa amazinga e-API SPEC 5L, EN10217, GB/T9711.1, GB/T9711.2. Isetshenziswa kakhulu embonini kawoyela negesi yemvelo ukuthutha uketshezi oluvuthayo kanye noketshezi olungashi kanye nezakhiwo zensimbi.
