Ukusebenza nemisebenzi yepayipi lensimbi yomthungo wombala wokuqala enqubweni ethile yokusetshenziswa kubonisa ngokugcwele umnikelo wokusebenza nokusebenziseka. Ngemuva kokudweba nokufafaza izinhlamvu ezimhlophe, ipayipi yensimbi ye-seam eqondile nayo ibonakala inamandla kakhulu futhi inhle. Manje ukufakwa kwamapayipi, kungakhathaliseki ukuthi amapayipi ensimbi e-carbon steel straight seam, amakhanda ensimbi ye-carbon steel noma ama-carbon steel tee, iziphambano, nokunye ukufakwa kwamapayipi ashiselwe, konke kunemibala yakhona yoqobo, yonga ezinqubweni. Noma ngabe ipendiwe, ibukeka iyinhle kuphela ngaleso sikhathi futhi isebenza ngenhloso yokuvimbela indawo engaphezulu ukuthi ingagqwali. Ngemva kokuba ipayipi lensimbi eliqondile lishiselwe epayipini, kusadingeka lipendwe ukuze kugwenywe ukugqwala. Bese uqhubeka nenqubo yokulondoloza ukushisa.

Ukusebenza kanye nemisebenzi yamapayipi ensimbi yomthungo oqondile kanye namapayipi ensimbi omthungo wombala wangempela enqubweni ethile yokusetshenziswa kubonisa ngokugcwele umnikelo wawo wokusebenza nokusebenza kwawo. Ngemva kokudweba, kwafafazwa ukubhala okumhlophe, futhi amapayipi ensimbi anomthungo oqondile nawo abukeka enamandla kakhulu futhi emuhle, enezela ukubukeka okuhle kakhulu. Kungani lokhu? Kunezizathu ezimbili. Kuvela ukuthi ipayipi lensimbi lomthungo oqondile ligcina umbala walo wangempela, futhi ungabona indawo yokuqala ngaphandle kokuphazanyiswa. Isikhathi sokwakhiwa kwamapayipi ensimbi eqondile angathuthukiswa, futhi angalayishwa futhi athunyelwe ngokushesha lapho ekhiqizwa. Lona umcabango wami nje.

Uthini umbala wasekuqaleni wepayipi lensimbi lomthungo? Isebenzisa amapayipi ensimbi ye-carbon ukukhiqiza amapayipi ensimbi aqondile akhona manje, amapayipi ensimbi angama-degree angu-90 aqondile, amapayipi ensimbi angu-45-degree aqondile, amakhanda, ama-elbow tee we-Hebei, nokunye ukufakwa kwamapayipi ashiselwe ngaphandle kokupenda nokunqanda ukugqwala. umbala oyinhloko. Lo mbala uhlanganisa obomvu (lena yindlela amapayipi ensimbi anomthungo oqondile akhiqizwa ngayo ngesikhathi sokukhiqiza), kanye ne-cyan, okuwumbala wokuqala wamapayipi ensimbi anomthungo oqondile. Amapayipi ensimbi anomthungo oqondile wangempela akhiqizwa futhi ayengeke athengiswe ngaphandle kopende wokugqwala. Iningi lazo liyimikhiqizo eseyiqediwe. Sekucishe kube umthetho wemboni. Uma kungenjalo, akubhekwa njengepayipi lensimbi eliqondile eliqondile. Ngesikhathi sokwakhiwa ebusika, amapayipi awathinteki kakhulu ekuthinteni nasekuqhekekeni, okwandisa ukuguquguquka kwezinhlelo zokwakha. Ayihambisani nemvelo futhi ingagaywa kabusha ngaphandle kokungcolisa imvelo. Ukwehluleka ukugaywa kabusha kuzodala ukungcola kwesibili; kunezinkinga ezifana nokulawula i-cross-linking degree kanye nokufana kwe-cross-linking, futhi ukucubungula kuyinkimbinkimbi futhi kuthinta ngokuqondile ukusebenza kwepayipi.

Amaphuzu amabili akufundisa ukuthi ungahlukanisa kanjani amapayipi ensimbi othungelwano oluqondile:
Hlukanisa amapayipi ensimbi othungelwano oluqondile ngokobubanzi bangaphandle
Lawo anobubanzi obungaphandle obuphakathi kuka-φ4.76 no-φ12.70 mm amapayipi ensimbi anobubanzi obuncane obuqondile; lawo anobubanzi obungaphandle phakathi kwe-φ13-φ114 mm amapayipi ensimbi anobubanzi obuncane obuqondile; lawo anobubanzi obungaphandle phakathi kwe-φ114-φ406 mm amapayipi ensimbi anobubanzi obuphakathi. Amapayipi ensimbi aqondile; lawo anobubanzi obungaphandle obukhulu kuno-φ406 mm amapayipi ensimbi anomugqa oqondile anobubanzi obukhulu.

Hlukanisa amapayipi ashiselwe ngokobukhulu bodonga
Ngokwesilinganiso sobukhulu bodonga t kuya epayipini lensimbi ububanzi bangaphandle D, amapayipi ashiselwe angahlukaniswa abe yizigaba ezinhlanu ezilandelayo:
①Lawo ane-t/D ngaphansi kuka-2% amapayipi anezindonga ezincane;
② Amashubhu anezindonga ezacile ane-t/D elingana no-2-5%;
③Lawo ane-t/D enkulu kuno-5-12% amapayipi oqobo ajwayelekile;
④Lawo ane-t/D enkulu kuno-12-18% amapayipi anezindonga eziwugqinsi;
⑤Lawo ane-t/D engaphezu kuka-18% amapayipi odonga akhethekile asekuqaleni.
Amashubhu anezindonga ezincane, amashubhu anezindonga ezijwayelekile, namashubhu anezindonga eziwugqinsi awahlukaniswa ngokomqondo ngenani lokuqina kodonga. Nokho, ezinye izindinganiso zinezindonga ezintathu ezihlukene ezihambisana nobubanzi obufanayo bangaphandle. Amapayipi analokhu kuqina kwezindonga ezintathu angase aqanjwe ngokuthi amapayipi anezindonga ezincane, amapayipi ashiselwe anokuqina odongeni, namapayipi ensimbi ajiyile aqondile ngokwendinganiso.
Ngenxa yokumelana nokugqwala, ukumelana ne-oxidation, i-anti-static, neminye imisebenzi ekhethekile yamapayipi ashiselwe ngomthungo oqondile, kanye nokubukeka okuhle nokuqina kwamapayipi ashiselwe ngomthungo oqondile, sekuphenduke umkhuba kancane kancane ukuwasebenzisa ukwenza imishini ethile. , izingxenye, neziphethu. Njengoba inqubo yezobuchwepheshe iqhubeka nokuvuthwa nokuzinza, ipayipi elishiselwe umkhiqizo wezimboni elithi "Xiangyang" eliye laqhubeka likhula futhi lithuthuka eminyakeni yamuva nje, lingena kancane kancane emikhakheni ehlukahlukene efana ne-hardware esebenzayo kanye nemboni yokwakha neyokuhlobisa ngeyingqayizivele yayo. ukusebenza kanye nokusebenza kwe-polynomial. Futhi njengoba abantu beya ngokuya bejwayelana nayo, isidingo sayo sizoya ngokuya sishesha kakhulu, futhi izinkundla zokusetshenziswa kwayo zizoba banzi futhi zibe banzi. Esinye isibonelo yizinduku zokushisela ezisetshenziswa kakhulu kanye nenani elikhulu lezingxenye zensimbi engagqwali, izixhumi, njll., amasimu azo nawo ahlaliswe kabanzi ngamapayipi ahlanganisiwe we-seam aqondile. Ukwengeza, ngokuthuthukiswa kanye nokusetshenziswa okunengqondo kwemikhiqizo yobuchwepheshe obuphezulu kuyo yonke ibhodi, ububanzi bokufakwa kwamapayipi ashiselwe ngomthungo oqondile nawo uye wanwetshwa nakakhulu. Izimboni eziningi ezidinga ukuthuthukisa izinto zokwakha sezamukele amapayipi ashiselwe ngomthungo oqondile. Okusobala kakhulu imboni yamakhemikhali kanye nemboni ye-fiber yamakhemikhali. Ukuguqulwa kwemishini yezimboni.
