Ipayipi lensimbi eludongeni eliwugqinsi libhekisela kububanzi bepayipi kanye nesilinganiso sokuqina kodonga esingaphansi kwama-20. Umehluko omkhulu phakathi kwepayipi lensimbi eliwugqinsi kanye nepayipi lensimbi eliwudonga elincane ukushuba kodonga lwepayipi, ngokuvamile, kudwetshwa ubuchwepheshe bensimbi enezindonga ezincane, futhi jikelele. ukusetshenziswa kobuchwepheshe bepayipi lensimbi eligoqiwe eligoqiwe eligoqiwe, uma lisetshenziselwa ukuhlukanisa phakathi kwamayunithi wokulinganisa, ngokuvamile, ubukhulu bodonga / ububanzi obulingana no-0.02 buwugqinsi futhi obuncane obunamapayipi ensimbi, ukushuba kodonga / ububanzi obuncane kunepayipi yensimbi engu-0.02 enodonga oluncane, ipayipi lensimbi eliwugqinsi likhulu kunezinjongo, insimbi enezindonga ezinezinjongo eziningi zepayipi.Izingxenye ezingenalutho zensimbi enezindonga eziningi ezisetshenziswa endaweni engenalutho.Ingcindezi kanye nesiteshi esibalulekile okufanele sisetshenziswe.

Insimbi ewugqinsi enezindonga ezisetshenziswa kakhulu kubunjiniyela bamanzi, imboni ye-petrochemical, imboni yamakhemikhali, imboni yamandla, ukuchelela ngenkasa kwezolimo, ukwakhiwa kwamadolobha.Ukuthutha uketshezi: ukuhlinzekwa kwamanzi kanye ne-drainage.Ezokuthutha ngegesi: igesi, umusi, igesi ye-petroleum ewuketshezi.Ngezinhloso zesakhiwo: njengepayipi lokunqwabelanisa lamabhuloho;amadokodo, imigwaqo, izakhiwo kanye nezinye izakhiwo tube.

Isihluthulelo sekhwalithi yepayipi eliwugqinsi lensimbi kufanele libe ukujiya okufanayo, ukushuba kwepayipi lensimbi enodonga alulawulwa kuthinte ngokuqondile ikhwalithi nokuba usizo kwepayipi lensimbi, ipayipi lensimbi eliwugqinsi, ipayipi elikhulu lensimbi elingenamthungo ukuze lisetshenziswe ezinhlobonhlobo. womshini, ugqinsi lwezingxenye zodonga olucutshungulwayo, ipayipi lensimbi eliwugqinsi elinezindonga eziwugqinsi lizothinta ngqo ikhwalithi yezingxenye ezicutshunguliwe, udonga lwamapayipi ensimbi aminyene alulawulwa, ikhwalithi yensimbi iyonke ayiqinile.

Welding obukhulu-ngodonga ipayipi yensimbi kuqala uwoyela ahlanzekile, upende, amanzi, nokugqwala, njll ke udonga inkatho, wavula inombolo enkulu obukhulu, mncane ukuze uvule inombolo encane (engela grinder), ke lokho phezu igebe umkhiqizo. , induku noma ucingo ububanzi ngokuvamile 1 - 1.5 izikhathi, uma unganakile groove wavulwa amagama ambalwa kungaba ezifanele ukuhlala encane.Tack welding okungenani ngehora lesithathu, ihora lesine ngokuvamile umsebenzi omuhle.Isikhathi se-welding kufanele sibe uhhafu nengxenye, siqala endaweni ephansi kakhulu, okungcono kakhulu kunesentimitha noma ngaphezulu, kuhle kakhulu kusuka kusixhumi esiphambene.Uma ipayipi ukushuba odongeni, kufanele layered, okungenani izingqimba ezimbili, ungqimba wokuqala wonke umbuthano baze baqede Welding kungaba Weld esitezi sesibili.

Mayelana ne-Thick-walledipayipi lensimbi engenamthungo

Ipayipi lensimbi eliqinile elinezindonga luhlobo lwesiphambano esingenalutho, akukho mithungo ezungeze ibha ende yensimbi.Ingxenye yensimbi engenalutho enenani elikhulu lamashaneli asetshenziselwa ukudlulisa uketshezi, njengamafutha okudlulisela, igesi, igesi, amanzi nezinye izinto eziqinile, amapayipi nokunye.Ipayipi lensimbi nensimbi eqinile eyindilinga bar, njll.

uma kuqhathaniswa namandla afanayo okugoqa ekugobeni, ukukhanya, insimbi yezomnotho yesigaba esiphambanayo, esetshenziswa kabanzi ekwenzeni izingxenye zesakhiwo nezingxenye zemishini, njengepayipi lokubhoboza, imishayo yezimoto, indiza yebhayisikili kanye nokwakhiwa kusetshenziswa isikafula sensimbi.Indandatho enezingxenye zokukhiqiza ipayipi lensimbi, ingathuthukisa ukusetshenziswa kwezinto, yenze lula inqubo yokukhiqiza, izinto zokonga kanye nokucubungula amahora omuntu, njengezindandatho ezithwalayo, amasethi ojeke, njll., sekusetshenziswe kabanzi ukwenza insimbi.Insimbi noma izinhlobonhlobo zezikhali ezijwayelekile ezibalulekile, umgqomo, umgqomo nezinye izinsimbi okufanele zenziwe.Ngokuma kwe-cross-sectional yepayipi ingahlukaniswa ibe yi-tube kanye ne-tube emise.Kusukela ukuzungeza kwezimo ezifanayo, indawo ephezulu yendilinga, enepayipi eliyindilinga ingathwala uketshezi oluningi.Ngaphezu kwalokho, indandatho cross-section ukumelana ingcindezi yangaphakathi noma yangaphandle radial, amandla ngokulinganayo, ngakho iningi ipayipi ipayipi.
