Emkhakheni wezakhiwo nengqalasizinda, ukukhethwa kwezinto zokwakha kunquma ngqo ukuqina nokusebenza kahle kwephrojekthi. Phakathi kwazo,Ipayipi le-ASTM A252, njengezinto eziyinhloko zobunjiniyela besisekelo senqwaba, idunyiswa kakhulu yimboni ngokusebenza kwayo okuhle kakhulu okusekelayo. Lesi sihloko sizohlanganisa imikhiqizo yamabhizinisi okukhiqiza asezingeni eliphezulu eCangzhou, sigxile ekuhlaziyeni Ubukhulu bepayipi le-ASTM A252futhiUsayizi Wepayipi we-ASTM A252, futhi sibonise ukusebenza okuvelele kwamapayipi enkampani yethu e-A252 grade 3 ahlanganiswe nge-arc welded ezisetshenziswayo njengamapayipi endle.
Iyini ipayipi le-ASTM A252?
Izinga le-ASTM A252 lihlanganisa amapayipi ensimbi ahlanganisiwe nangenamthungo asetshenziswa kubunjiniyela besisekelo sezinqwaba, asetshenziswa kabanzi kumaBridges, izisekelo zezakhiwo eziphakeme kanye nezinye izakhiwo ezidinga amandla aphezulu kanye nokusekelwa okuthembekile. Leli zinga lihlukaniswe ngamagremu amathathu, phakathi kwawo amapayipi eBanga lesi-3 enza kahle kakhulu ngokwamandla nokuqina, futhi afaneleka kakhulu ezimweni zokusetshenziswa ezisindayo nezinomthwalo omningi.
Ukuhlaziywa kobukhulu bepayipi le-ASTM A252 kanye nokucaciswa
Kwabonjiniyela kanye nabenzi bezinqumo zephrojekthi, ukuqonda ngokunembile Ubukhulu Bepayipi le-ASTM A252 kuyisihluthulelo sokukhetha umklamo. Lolu hlobo lwepayipi lunikeza osayizi bepayipi le-ASTM A252 abaguquguqukayo. Ububanzi bobubanzi buvame ukuba phakathi kwamasentimitha angu-6 namasentimitha angu-60, futhi ubukhulu bodonga bungalungiswa ngokuya ngezidingo zangempela zobunjiniyela.
Isibonelo, imininingwane evamile yamapayipi ingaba ububanzi obungamasentimitha angu-12 kanye nobukhulu bodonga obungamasentimitha angu-0.375. Sisekela ukukhiqizwa okwenziwe ngokwezifiso ukuqinisekisa ukuthi ipayipi ngalinye linezakhiwo zemishini kanye nokuqina okudingekayo kuphrojekthi, lihlangabezana nazo zonke izidingo kusukela kubunjiniyela bomasipala kuya engqalasizinda yezimboni enkulu.
Amandla ebhizinisi: Kwenziwe eCangzhou, ikhwalithi idlulisiwe
Inkampani yethu itholakala eDolobheni laseCangzhou, eSifundazweni saseHebei. Selokhu yasungulwa ngo-1993, ibilokhu izinikele ekukhiqizweni kwamapayipi ensimbi kanye nokusungula izinto ezintsha kwezobuchwepheshe. Le nkampani ihlanganisa indawo engamamitha-skwele angu-350,000, inempahla ephelele engama-yuan ayizigidi ezingu-680 futhi iqasha abantu abacishe babe ngu-700. Sethule imishini yokukhiqiza nokuhlola ethuthukisiwe yamazwe ngamazwe ukuqinisekisa ukuthi yonkeIpayipi le-ASTM A252ukuphuma efektri kuhambisana noma kudlule ngisho nezindinganiso zemboni.
Ipayipi Elihlanganisiwe Elihlanganisiwe Elihlanganisiwe Elihlanganisiwe Eliyi-A252 Grade 3: Ukukhetha okuhle kwezinhlelo zamapayipi okuhambisa indle
Umkhiqizo ohamba phambili wenkampani yethu, ipayipi elihlanganisiwe le-arc elihlanganisiwe lebanga lesi-3 eliyi-spiral arc, lenziwa kusetshenziswa inqubo yokushisela i-arc ehlanganisiwe ye-spiral (SAWH). Umthungo wokushisela uyafana futhi uqinile, unamandla aphezulu esakhiwo kanye nokumelana okuhle kakhulu kokucindezela nokugoba.
Lo mkhiqizo wenziwe ngensimbi esezingeni eliphezulu futhi unokumelana okuhle kakhulu nokugqwala kanye nokumelana nokuguguleka, okwenza ufaneleke kakhulu ezindaweni ezinzima njengokwelashwa kwendle kanye nokushayela inqwaba yesisekelo. Sisebenzisa uhlelo lokulawula ikhwalithi kuyo yonke inqubo. Kusukela ezintweni zokusetshenziswa ezingena efektri kuya emikhiqizweni eqediwe ephuma efektri, inqubo ngayinye ilandela ngokuqinile indinganiso ye-ASTM A252 ukuqinisekisa ubukhulu obunembile bepayipi kanye nokusebenza okuthembekile.
Isiphetho
Ipayipi le-ASTM A252 lidlala indima engenakuphindwa esikhundleni engqalasizinda yesimanje. Osayizi balo bepayipi le-ASTM A252 abaguquguqukayo kanye nobukhulu bepayipi le-ASTM A252 obujwayelekile bunikeza isiqinisekiso esiqinile samaphrojekthi ahlukahlukene obunjiniyela. Njengebhizinisi lokukhiqiza elihamba phambili endaweni yaseCangzhou, elineminyaka engama-30 yokuqongelela ubuchwepheshe kanye nokuphishekela ikhwalithi engaguquki, sinikeza amakhasimende imikhiqizo yepayipi elihlanganisiwe le-A252 elinomoya oqinile futhi elihlala isikhathi eside. Ukukhetha thina kusho ukukhetha inketho ehlala njalo neqinisekisayo yephrojekthi yakho yengqalasizinda.
