20# umakhi wepayipi lensimbi engenamthungo
Ipayipi eliwuketshezi uhlobo lwepayipi lensimbi elinengxenye engenalutho futhi alikho ukushisela kusukela ekuqaleni kuya ekugcineni. Ipayipi lensimbi linendawo engenalutho, esetshenziswa kakhulu njengepayipi lokudlulisa uketshezi, uwoyela, igesi yemvelo, igesi, amanzi nezinye izinto eziqinile. Uma kuqhathaniswa nensimbi eqinile njengensimbi eyindilinga, ipayipi lensimbi inokugoba okufanayo namandla okugoqa kanye nesisindo esilula. Kuyinsimbi yesigaba sezomnotho. Isetshenziswa kakhulu ekwenzeni izingxenye zesakhiwo kanye nezingxenye zemishini, njengepayipi lokubhoboza uwoyela, umshini wokuhambisa imoto, uhlaka lwamabhayisikili kanye nesikafula sensimbi esisetshenziswa ekwakheni.
I-Fluid pipe iyipayipi elisetshenziswa ngokukhethekile ukuthutha imidiya enezinto eziwuketshezi.
Ngokungeziwe emithonjeni ewuketshezi efana namanzi, uwoyela nesisombululo, imidiya eqinile njengosimende, okusanhlamvu namalahle agayiwe kungageleza ngaphansi kwezimo ezithile.
Amapayipi anoketshezi angenziwa ngensimbi, izinsimbi ezingenayo insimbi njengethusi ne-titanium, ngisho nezinto ezingezona ezensimbi njengamapulasitiki.
Ipayipi eliwuketshezi kufanele libe nengxenye engenalutho, kodwa futhi lingaba isikwele, unxantathu noma yimuphi omunye umumo. Eminye imishini kufanele isebenzise ipayipi elingunxande ngenxa yesimo esilinganiselwe, kodwa iningi lisasebenzisa ipayipi eliyindilinga. Ithubhu eyindilinga inesilinganiso esincane kunazo zonke se-circumference / area kuzo zonke izigaba zejometri, okungukuthi, ingxenye enkulu yangaphakathi ingatholakala ngaphansi kwesimo sokusebenzisa inani elifanayo lezinto.
Ipayipi lensimbi lisetshenziswa kakhulu ekuthuthweni koketshezi emphakathini wanamuhla ngenxa yezindleko eziphansi namandla aphezulu. Ngokwenqubo yayo yokukhiqiza, amapayipi ensimbi ahlukaniswe ngamapayipi ensimbi angenamthungo namapayipi ashiselwe. Amapayipi ashiselwe aphinde ahlukaniswe abe amapayipi ashiselwe i-high-frequency straight seam welded pipes (RW), amapayipi ashiselwe ajiyile (SSAW), amapayipi ashiselwe i-arc angaphansi kwamanzi (UOE), njll. Ngaphambilini, amapayipi ensimbi angenamthungo ayesetshenziselwa amapayipi oketshezi. Ngokuthuthuka nokuthuthuka kwesayensi yezinto ezibonakalayo, ukwakha ubuchwepheshe kanye nemishini yamayunithi, amapayipi ashiselwe athuthukiswe kakhulu. Ipayipi elishiselwe linezinzuzo zokufana okungcono kodonga, ukunemba okuphezulu, ukusetshenziswa kwamandla okuncane kanye nokusebenza kahle kokukhiqiza okuphezulu kunepayipi elingenamthungo. Esikhathini esedlule, cishe u-100% wepayipi elingenamthungo lalisetshenziselwa ipayipi lokuhambisa uwoyela negesi (okujwayelekile kwe-API). Namuhla, ezingaphezu kuka-95% zazo zithathelwe indawo ngamapayipi ashiselwe e-United States, Japan kanye namazwe athuthukile aseYurophu.
① Ngokuvamile, izinga lokushisa lesevisi lamashubhu okubhayela lingaphansi kuka-450 ℃, futhi amashubhu asekhaya enziwa ngokuyinhloko nge-No. 10 kanye ne-No.
②Amashubhu kabhayela anomfutho ophakeme avame ukuba sezingeni lokushisa eliphezulu nezimo zokucindezela okukhulu. Amashubhu azofakwa i-oxidized futhi agqwale ngaphansi kwesenzo sokushisa okuphezulu kwegesi ye-flue kanye nesitimu. Ipayipi lensimbi liyadingeka ukuze libe namandla ahlala njalo, i-anti-oxidation ephezulu nokusebenza kokugqwala kanye nokuzinza okuhle kwesakhiwo.
