Ingahlukaniswa ngendololwane ye-radius ende kanye nendololwane ye-radius emfushane.Indololwane ye-radius ende ibhekisela kububanzi obungaphandle bepayipi okuyindawo yayo yokugoba ilingana nezikhathi ezingu-1.5, okungukuthi, R=1.5D;Indololwane ye-radius emfushane isho ukuthi i-radius yayo yokugoba ilingana nobubanzi obungaphandle bepayipi, okungukuthi, R= 1.0d.(D ingububanzi bendololwane, u-R uyiradius of curvature).5. Ngokwezinga lokucindezela, kunezinhlobo ezingaba ngu-17 zamashubhu, afana namazinga aseMelika, okuhlanganisa i-Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS;Sch80, SCH100, Sch120, Sch140, Sch160, XXS Okubili okuvame ukusetshenziswa kakhulu yi-STD ne-XS
Ithemba lokuthuthukiswa kwemboni yezinto zokwakha
I-China isivele ingumkhiqizi nomthengi omkhulu wezinto zokwakha.Ukukhiqizwa kukasimende, ingilazi yepuleti, izitsha zobumba ezihlanzekile, izinto zamatshe nezodonga kukleliswe kuqala emhlabeni iminyaka eminingi.Ngesikhathi esifanayo, izinga lezinto zokwakha liqhubeka lithuthuka, ukusetshenziswa kwamandla nezinto zokusetshenziswa kuncipha unyaka nonyaka, zonke izinhlobo zezinto zokwakha ezintsha zilokhu zivela, izinto zokwakha ziqhubeka nokuthuthuka, imboni yokukhiqiza imishini yamapayipi e-cangzhou inesisekelo esiqinile.Le nkampani inamabhizinisi okukhiqiza angaphezu kuka-3,200, phakathi kwawo amabhizinisi angama-222 angaphezu kwesikali (imali yokuthengisa engaphezu kwama-yuan ayizigidi ezi-5), aqasha abantu abayi-124,000.Imikhiqizo eyinhloko yizo zonke izinhlobo zensimbi ekhethekile, insimbi engagqwali, i-carbon steel namanye amashubhu ensimbi angenamthungo, amashubhu abhayela aphansi, aphakathi nendawo naphezulu, amashubhu okumba uwoyela namanye amashubhu;Zonke izinhlobo zezindlela ezintathu, ezine, i-valve, ukufakwa kwendololwane yepayipi yokunciphisa;Zonke izinhlobo ze-stainless steel flange, i-flange eyakhiwe;Zonke izinhlobo zohlaka lwamapayipi, insimbi, isivimbeli sokuqhunyiswa kukawoyela nezinye izesekeli zamapayipi;Amapayipi e-polyethylene ahlukahlukene, amapayipi e-polypropylene namanye amapayipi epulasitiki, ingqikithi yezigaba eziyi-16 zezinhlobo ezingaphezu kuka-370 zokucaciswa okungaphezu kuka-3500.Inqubo yokukhiqiza ithatha ngokuyinhloko i-hot rolling straight seam welding, i-spiral arc welding enezinhlangothi ezimbili ezingaphansi komhlaba, i-forging, i-forging, i-medium frequency push system, ukwakheka okubandayo, i-extrusion eshisayo nokunye.Ubukhulu bokucubungula ububanzi bepayipi ngu-2020mm.Imikhiqizo isetshenziswa kakhulu kubunjiniyela bakamasipala, ubunjiniyela be-petrochemical, ukudluliswa kwegesi entshonalanga-empumalanga, ukwakhiwa kwemikhumbi kanye nobunjiniyela bamandla enuzi, enomklamo wonyaka kanye namandla okucubungula amathani ayizigidi ezingama-25.Ngo-2010, inani elingeziwe lezimboni lamabhizinisi elingaphezu kobukhulu obunqunyiwe lafinyelela kuma-yuan ayizigidi eziyizinkulungwane ezingu-13, lenyuka ngo-31.7% unyaka nonyaka, libalelwa ku-16.1% yenani elingeziwe lawo wonke amabhizinisi angaphezu kosayizi obumisiwe.Imboni yokukhiqiza imishini yamapayipi yaseCangzhou ithuthukela ezinhlosweni “zezinto ezintathu eziphakeme” (isilinganiso esiphezulu, izinga eliphezulu nemishini ephezulu) kanye “nezintathu eziphakeme” (ezisezingeni eliphezulu, ezinomfutho ophezulu kanye nenani eliphakeme elengeziwe), kanye nokukhuthaza amandla okukhiqiza imishini yamapayipi. ukufinyelela amathani ayizigidi ezingama-30.I-Cangzhou izoba “isizinda sokukhiqiza imishini yamapayipi kanye nesizinda se-R&D” kanye “nemali yemishini yamapayipi” eyaziwayo.Ukutshalwa kwezimali ekwakhiweni “koHlelo Lweminyaka Emihlanu Lweminyaka Eyi-11” sekufinyelele esigabeni esimaphakathi.Ukukhula okunamandla komgwaqo onguthelawayeka, ujantshi wesitimela nokunye ukutshalwa kwezimali ekwakhiweni kwengqalasizinda kanye nokukhula okuqhubekayo kokutshalwa kwezimali okuvamile kwezakhiwo kwenza imboni yezokwakha ibe sezingeni eliphezulu.Ngaso leso sikhathi, ngaphansi kwesizinda sokwakha umphakathi owonga ugesi kanye nokuqinisa amandla okusebenza azimele wezwe, indikimba yokongiwa kwamandla kanye nokuqanjwa kabusha kwezobuchwepheshe kuzoba indawo eshisayo yentuthuko yemboni.
