Spiral pipe fektheri e lokela ho etsoa pele ho tlhahlobo ea ts'ebetso ea mochini le tlhahlobo ea flattening, le tlhahlobo ea flaring, le ho fihlela litlhoko tse tloaelehileng.Mokhoa oa ho hlahloba boleng ba phala ea tšepe ea Spiral ke ka tsela e latelang:
1, Ho tloha sefahlehong sa eona, ke tlhahlobo ea pono.Tlhahlobo e bonoang ea manonyeletso a cheselitsoeng ke mokhoa o bonolo empa mokhoa oa tlhahlobo o sebelisoang haholo ke karolo ea bohlokoa ea tlhahlobo ea sehlahisoa, bofokoli bo boholo le ho kheloha li fumanoa holim'a boholo ba weld.Hangata ka leihlo le hlobotseng, ka mohlala o tloaelehileng, gauge le lisebelisoa tsa tlhahlobo tse kang khalase e hōlisang.Haeba weld surface e na le bokooa, mefokolo ea weld e ka ba teng kahare.

2, Mekhoa ea tlhahlobo ea 'mele: mokhoa oa tlhahlobo ea' mele ke ho sebelisa tlhahlobo ea liketsahalo tsa 'mele kapa mokhoa oa tlhahlobo.Kapa ka har'a tlhahlobo ea bofokoli ba lisebelisoa, 'me hangata ho sebelisoa mekhoa ea NDT.Ho sibolla liphoso tsa NDT, ho lemoha mahlaseli, tlhahlobo ea ho kenella, tlhahlobo ea matla a khoheli joalo-joalo.

3, Teko ea matla a likepe tsa khatello: likepe tsa khatello, ntle le teko ea boima, empa hape le teko ea matla.Ho na le liteko tse tloaelehileng tsa liteko tse peli tsa hydraulic le khatello ea moea.Li ka lekoa ha li sebetsa tlas'a likepe tsa khatello le piping welds compactness.Teko ea khatello ea Hydrostatic e na le kutloelo-bohloko ho feta lebelo la teko, 'me ka nako e ts'oanang ka mor'a hore lihlahisoa tsa tlhahlobo li se ke tsa senya phekolo ea metsi, mathata a drainage bakeng sa sehlahisoa a sebetsa ka ho khetheha.Empa kotsi e kholo ho feta teko ea khatello ea teko.Ha e lekoa, e tlameha ho ikamahanya le mehato e nepahetseng ea polokeho ho thibela likotsi nakong ea tlhahlobo.

4, Teko ea Compact: tjheseletsa ea sejana sa metsi kapa sa khase, e seng mefokolo e teteaneng ea weld, joalo ka mapetsong a phunyeletsang, li-pores, slag, ho kenella ho sa phetheheng ha lisele tse hlephileng le tse ling tse joalo, li ka sebelisoa ho fumana tlhahlobo ea letsoalo.Mekhoa ea tlhahlobo ea ho kopana ke: tlhahlobo ea parafine, ho nka tlhahlobo ea metsi, metsi a tla leka.

5, Teko ea hydrostatic e lokela ho etsoa tlhahlobo e 'ngoe le e' ngoe ea phala ea hydrostatic ntle le ho lutla, khatello ea teko ea khatello Bala P = 2ST / D moo S- hydrostatic test stress test Mpa, tlhahlobo ea khatello ea maikutlo ea hydrostatic ho latela maemo a tšepe a tsamaisanang a hlalosang tekanyo e fokolang ea chai ( Q235 ke 235Mpa) 60% ea khetho.Nako ea balaoli: D <508 khatello ea teko ea ho tšoara nako e ka tlase ho metsotsoana ea 5;D≥508 khatello ea teko e tšoereng nako e ka tlase ho metsotsoana e 10 4, tlhahlobo e sa senyeheng ea seam welding ea tšepe, li-strip end weld le manonyeletso a circumferential li lokela ho hlahlojoa ke X-ray kapa ultrasonic.Bakeng sa lipalangoang tse tloaelehileng tsa mokelikeli oa tšepe ho cheselletsa e lokela ho ba 100% SX-ray kapa tlhahlobo ea ultrasound, e sebelisetsoang metsi, likhoerekhoere, moea, mouoane o futhumatsang le mokelikeli o mong o akaretsang o nang le phala ea tšepe ea spiral e lokela ho ba X-ray kapa licheke tsa tlhahlobo ea ultrasonic ( 20%).

Liphetho tsa tlhahlobo ea boleng ba phala ea tšepe ea spiral, pipe ea spiral hangata e arotsoe ka mekhahlelo e meraro: E tšoanelehang, e sebetsang bocha le e senyehileng.Tšoanelehang e bolela boleng le ponahalo ea boleng bo ka hare ho kopana le litekanyetso kapa phano ea tekheniki le maemo a kamohelo spiral steel pipe;rework e bua ka boleng le ponahalo ea boleng bo ka hare ha e lumellane ka botlalo le litekanyetso tsa ho amoheloa le ho hlobola 'mele, empa lumella ho lokisoa ka mor'a ho lokisoa ho ka finyella litekanyetso le maemo a ho amohela spiral pipe;litšila li bua ka boleng bo sa tsitsang le ponahalo ea boleng bo kahare ba tšepe ea spiral e ntse e sa fihle maemong a tloaelehileng mme maemo a kamohelo ha a lumelle ho lokisoa kapa ho sebetsa bocha hamorao.
