Ipayipi Lensimbi Engenamthungo Yezokuthutha Eziwuketshezi

Ipayipi Lensimbi Engenamthungo Lokuthutha Okuwuketshezi Isithombe Esifakiwe

Incazelo emfushane:

321 ipayipi lensimbi engagqwali. Ipayipi lensimbi elingenamthungo (i-GB14976-2002) lisetshenziselwa ukukhiqiza amapayipi esitimu ashisa kakhulu, amapayipi amanzi abilayo ama-boilers anomfutho ophansi naphakathi wezakhiwo ezahlukahlukene kanye namapayipi esitimu esishisa kakhulu samabhoyili esitimela, amapayipi amakhulu entuthu, amapayipi amancane entuthu kanye namapayipi esitini esikhothamo. Insimbi yesakhiwo sekhabhoni amashubhu ensimbi ashisayo ashibilike nadonswa kubanda (agingqelwe).

1. 321 ipayipi lensimbi engagqwali. Ipayipi lensimbi elingenamthungo (i-GB14976-2002) lisetshenziselwa ukwakha amapayipi esitimu ashisa kakhulu, amapayipi amanzi abilayo kanye namapayipi esitimu esishisayo esishisayo, amapayipi amakhulu entuthu, amapayipi amancane entuthu kanye namapayipi esitina e-arch ezakhiwo ezihlukahlukene. Insimbi yesakhiwo sekhabhoni amashubhu ensimbi ashisayo ashibilike nadonswa kubanda (agingqelwe).

2. Amapayipi ensimbi engagqwali angu-321: insimbi yesakhiwo sekhabhoni yekhwalithi ephezulu, insimbi yesakhiwo sengxubevange kanye namapayipi ensimbi evikela ukushisa engenamthungo asetshenziselwa ikakhulukazi ukwakha amapayipi anomfutho ophezulu nangaphezulu. Lawa mapayipi ama-boiler ngokuvamile angaphansi kokushisa okuphezulu nokucindezela okukhulu. Umsebenzi namapayipi kuzophinde kufakwe i-oxidation kanye nokugqwala ngaphansi kwesenzo segesi ephuma emazingeni okushisa aphezulu kanye nomhwamuko wamanzi. Ngakho-ke, amapayipi ensimbi adingeka ukuba abe namandla aphezulu ahlala njalo, ukumelana ne-oxidation ephezulu, nokuzinza okuhle kwenhlangano. Amapayipi we-Hydraulic prop.

3. Amabanga ensimbi asetshenziselwa amapayipi ensimbi engagqwali angu-321 yilawa: 304 321 316 317 310, njll.

4. Ingxubevange yesakhiwo steel pipe steel amabanga 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, njll; kukhona insimbi engagqwali ukumelana nokushisa evame ukusetshenziswa 1Cr18Ni9, 1Cr18Ni11Nb high-pressure boiler tubes, ngaphezu kokuqinisekisa ukwakheka kwamakhemikhali kanye nezakhiwo zemishini, ukucindezela kwamanzi kufanele kwenziwe ngamunye ngamunye. Ukuze kuhlolwe, ukuhlolwa kwe-flaring kanye nokunciphisa kufanele kwenziwe.

5. Amapayipi ensimbi engagqwali angu-321 alethwa esimweni esiphethwe ukushisa. Ngaphezu kwalokho, kunezidingo ezithile ze-microstructure, usayizi wokusanhlamvu, kanye nesendlalelo se-decarburized yepayipi lensimbi eliqediwe. Amapayipi ensimbi angenamthungo wokumba i-geological kanye nokulawula ukumba uwoyela; sebenzisa imishini yokumba ukuze kubhodwe imithombo yokuhlolwa kwesakhiwo samadwala angaphansi komhlaba, amanzi angaphansi komhlaba, uwoyela, igesi yemvelo kanye nemithombo yamaminerali. Ukuhlola i-petroleum negesi yemvelo akuhlukaniseki nakakhulu nokumbiwa kwemithombo. Amapayipi ensimbi angenamthungo wokumba nokulawula i-geological ayisisetshenziswa esikhulu sokumba, okuhlanganisa amashubhu angaphandle angaphakathi, amashubhu angaphakathi angaphakathi, ama-casings, namapayipi okubhoboza. Ngenxa yokuthi ipayipi lokumba lidinga ukujula ekujuleni kokwakheka okungamakhilomitha ambalwa ukuze lisebenze, ipayipi lengxubevange engu-1cr5mo.

6. Izimo zokusebenza zinzima kakhulu. Ipayipi lokubhoboza libhekene nezingcindezi ezifana nokushuba, ukucindezelwa, ukugoba, ukugoqa, kanye nomthwalo ongalingani womphumela, kanye nokuguga kodaka namatshe. Ngakho-ke, ipayipi kufanele libe namandla anele, ukuqina, ukumelana nokugqoka kanye nokuqina kwe-Impact, ipayipi lensimbi elisetshenziswa "DZ" (isiqalo se-Geological Pinyin) kanye nenombolo eyodwa ukumela iphuzu lokuvunwa kwensimbi, amamaki ensimbi asetshenziswa ngokuvamile angama-45MnB, 50Mn DZ45; DZ50 40Mn2, 40Mn2Si; DZ55 40Mn2Mo, 40MnVB; 40MnMoB ye-DZ60, 27MnMoVB ye-DZ65. Amapayipi ensimbi ahanjiswa esimweni sokushisa.

7. Amapayipi aqhekeka uphethiloli: amapayipi angenamthungo amapayipi esithandweni, amapayipi okushintsha ukushisa kanye namapayipi asetshenziswa ezindaweni zokuhluza uphethiloli. Insimbi esetshenziswa kakhulu yekhwalithi ephezulu yekhabhoni (10, 20), i-alloy steel (12CrMo, 15CrMo), insimbi engashisi (12Cr2Mo, 15Cr5Mo), ukukhiqiza insimbi engagqwali (1Cr18Ni9, 1Cr18Ni9Ti).

8. Amapayipi ensimbi angenamthungo amapayipi ensimbi engagqwali angama-321 (GB3087-1999) asetshenziselwa ukukhiqiza amapayipi esitimu ashisa kakhulu, amapayipi amanzi abilayo kanye namapayipi esitiyela esishisayo esishisayo, amapayipi amakhulu entuthu, amapayipi amancane entuthu kanye namapayipi esitina e-arch ezakhiwo ezahlukahlukene eziphansi neziphansi. ama-boilers okucindezela okuphakathi. Ikhwalithi ephezulu ye-carbon structural steel amashubhu ensimbi angenamthungo nadonswa ngokubanda (agingqiwe). Ipayipi lensimbi engagqwali ye-321: Isetshenziselwa ikakhulukazi ukwenza insimbi yesakhiwo sekhabhoni ephezulu, insimbi yesakhiwo sengxubevange kanye namapayipi ensimbi angenamthungo angangeni ekushiseni amapayipi okubhayela esitimu engcindezi ephezulu nangaphezulu. Lawa mapayipi obhayela asebenza ngaphansi kokushisa okuphezulu nokucindezela okukhulu. , Ipayipi izokwenziwa i-oxidized futhi igqwale ngaphansi kwesenzo sokushisa okuphezulu kwegesi ye-flue kanye nomhwamuko wamanzi. Ngakho-ke, ipayipi lensimbi liyadingeka ukuze libe namandla ahlala njalo, ukumelana ne-oxidation ephezulu, nokuzinza okuhle kwenhlangano, ipayipi le-hydraulic prop.

9. Amapayipi ensimbi engagqwali angu-321 alethwa esimweni esiphethwe ukushisa. Ngaphezu kwalokho, kunezidingo ezithile ze-microstructure, usayizi wokusanhlamvu, kanye nesendlalelo se-decarburized yepayipi lensimbi eliqediwe. Amapayipi ensimbi angenamthungo wokumba i-geological kanye nokulawula ukumba uwoyela; sebenzisa imishini yokumba ukuze kubhodwe imithombo yokuhlolwa kwesakhiwo samadwala angaphansi komhlaba, amanzi angaphansi komhlaba, uwoyela, igesi yemvelo kanye nemithombo yamaminerali.
