Emkhakheni wezokwakha nengqalasizinda, ukukhethwa kwezinto zokwakha kunquma ngokuqondile ukuqina nokusebenza kahle kwephrojekthi. Phakathi kwazo,Ipayipi le-ASTM A252, njengengqikithi yobunjiniyela besisekelo senqwaba, inconywa kakhulu imboni ngokusebenza kwayo okuhle kakhulu okusekelayo. Lesi sihloko sizohlanganisa imikhiqizo yamabhizinisi akhiqizayo asezingeni eliphezulu eCangzhou, sigxile ekuhlaziyeni Ubukhulu bepayipi le-ASTM A252futhiAmasayizi wepayipi we-ASTM A252, futhi sibonise ukusebenza okuvelele kwamapayipi ashiselwe enkampanini yethu A252 grade 3 spiral submerged arc asetshenziswa njengamapayipi endle.
Liyini ipayipi le-ASTM A252?
I-ASTM A252 ejwayelekile ihlanganisa amapayipi ensimbi ahlanganisiwe nangenamthungo asetshenziswa kubunjiniyela besisekelo senqwaba, asetshenziswa kabanzi kumaBhuloho, izisekelo zezakhiwo eziphakeme kanye nezinye izakhiwo ezidinga amandla aphezulu nokusekelwa okuthembekile. Leli zinga lihlukaniswe ngamabanga amathathu, phakathi kwawo amapayipi eBanga lesi-3 enza kahle kakhulu ngokwamandla nokuqina, futhi afaneleka ngokukhethekile ezimweni zokufaka izicelo ezisindayo kanye nemithwalo ephezulu.
Ukuhlaziywa kwe-ASTM A252 Pipe Dimensions kanye Nemininingwane
Konjiniyela nabenzi bezinqumo zephrojekthi, ukubamba ngokunembile Ubukhulu bepayipi ye-ASTM A252 kuyisihluthulelo sokukhetha ukuklama. Lolu hlobo lwePipe lunikeza usayizi wamapayipi we-ASTM A252 oguquguqukayo. Ububanzi bobubanzi buvamise ukuba phakathi kwamayintshi angu-6 no-60, futhi ukujiya kodonga kungalungiswa ngokuvumelana nezidingo zangempela zobunjiniyela.
Isibonelo, ukucaciswa kwamapayipi okuvamile kungaba ububanzi obungama-intshi angu-12 kanye nogqinsi lwama-intshi angu-0.375. Sisekela ukukhiqizwa okungokwezifiso ukuze siqinisekise ukuthi ipayipi ngalinye linezakhiwo zemishini nokuzinza okudingekayo kulo msebenzi, lihlangabezana nazo zonke izidingo kusukela kobunjiniyela bakamasipala kuya engqalasizinda yezimboni ezinkulu.
Amandla ebhizinisi: Kwenziwe e-Cangzhou, ikhwalithi yehlile
Inkampani yethu itholakala eCangzhou City, eSifundazweni saseHebei. Kusukela yasungulwa ngo-1993, iye yanikezelwa ekwenziweni kwamapayipi ensimbi kanye nokusha kwezobuchwepheshe. Le nkampani ihlanganisa indawo engamamitha-skwele angu-350,000, inezimpahla eziphelele zamayuan ayizigidi ezingu-680 futhi iqashe abantu abacishe babe ngama-700. Sethule imishini yokukhiqiza nokuhlola ethuthukile emhlabeni wonke ukuze siqinisekise ukuthi zonkeIpayipi le-ASTM A252ukushiya imboni kuthobela noma kudlule ngisho namazinga omkhakha.
I-A252 Grade 3 Spiral Submerged arc Welded Pipe: Inketho ekahle yamasistimu amapayipi endle
Umkhiqizo wenkampani yethu ohamba phambili, i-A252 grade 3 spiral submerged arc welded pipe, ukhiqizwa kusetshenziswa inqubo ye-spiral submerged arc welding (SAWH). I-weld seam ifana futhi iqinile, inamandla esakhiwo esiphezulu kanye nokumelana okuhle kakhulu nokucindezela nokugoba.
Lo mkhiqizo wenziwe ngensimbi yekhwalithi ephezulu futhi ubonisa ukumelana nokugqwala okuhle kakhulu nokumelana nokugqokwa, okuwenza ufaneleke kakhulu ezindaweni ezinokhahlo ezinjengokuhlanza indle nokushayela inqwaba yesisekelo. Sisebenzisa isistimu yokulawula ikhwalithi kuyo yonke inqubo. Kusukela ezintweni zokusetshenziswa ezingena efektri kuya emikhiqizweni ephelile ephuma efektri, inqubo ngayinye ilandela ngokuqinile izinga le-ASTM A252 ukuze kuqinisekiswe ubukhulu obunembile bepayipi nokusebenza okuthembekile.
Isiphetho
I-ASTM A252 Pipe idlala indima engenakuthathelwa indawo nengqalasizinda yesimanje. Ubukhulu bayo bepayipi be-ASTM A252 obuguquguqukayo kanye nobukhulu obujwayelekile bepayipi le-ASTM A252 kunikeza isiqinisekiso esiqinile samaphrojekthi ahlukahlukene wobunjiniyela. Njengebhizinisi lezokukhiqiza elihamba phambili endaweni yaseCangzhou, elineminyaka engu-30 yokunqwabelana kwezobuchwepheshe kanye nokuphishekela izinga okungantengantengi, sihlinzeka amakhasimende ngemikhiqizo yamapayipi ashiselwe anokwethenjelwa kakhulu futhi ephila isikhathi eside A252 grade 3 spiral arc arc welded. Ukusikhetha kusho ukukhetha inketho ehlala njalo neqinisekisayo yephrojekthi yakho yengqalasizinda.
