Tsebisa:
Spiral welded pipe ke karolo ea bohlokoa mererong e fapaneng ea meralo ea motheo, ho kenyeletsoa lipeipi tsa oli le khase, lits'ebetso tsa phano ea metsi, le lits'ebetso tsa meralo.Joalo ka sehlahisoa se seng le se seng sa boenjiniere, lintlha tse ikhethileng li tlameha ho lateloa ho netefatsa ts'ebetso le ts'epahalo ea liphaephe tsena.Ka blog ena, re tla delve ka intricacies easpiral welded pipe specificationsho fana ka tataiso e felletseng ea ho utloisisa hamolemo sehlahisoa sena sa bohlokoa sa indasteri.
1. Tlhaloso le melemo:
Mokhoa oa ho etsa thepa eapipi e cheselitsoeng ka spiralke ho cheseletsa tšepe e kolobisitsoeng e chesang hore e be sebopeho sa spiral ka ho tsoela pele ho etsa spiral.Mekhoa e hlobolisa e kopantsoe hammoho ho sebelisoa litšepe tse nang le mahlakore a mabeli a tlas'a metsi (DSAW) ho etsa phala e matla a phahameng ka ho tšoarella ho matlafalitsoeng le ho hanyetsa deformation.Melemo e ka sehloohong ea phala e cheselitsoeng ea spiral e kenyelletsa botšepehi bo botle ba sebopeho, matla a ts'oanang ka bolelele ba phala, le bokhoni ba ho mamella likhatello tse phahameng tsa ka hare.
2. Diameter le botenya ba lebota:
Litlhaloso tsa liphaephe tse nang le spiral welded li kenyelletsa likarolo tse fapaneng, tse mahlonoko ka ho fetisisa ke bophara le botenya ba lebota la phala.Litekanyo tsena li ipapisitse le ts'ebeliso e reriloeng le maemo a ts'ebetso.Ka kakaretso, peipi e cheselitsoeng ka spiral e fumaneha ka bophara bo boholo ho feta peipi e tjheselitsoeng e se nang moroallo kapa e otlolohileng, eo hangata e tlohang ho lisenthimithara tse 8 ho isa ho tse 126 (203.2 ho isa ho 3200 limilimithara) kapa ho feta.Botenya ba lebota bo tloha ho 6 mm ho isa ho 25.4 mm kapa ho feta.
3. Kereiti ea tšepe le sebopeho sa lik'hemik'hale:
Khetho ea boemo ba tšepe le sebopeho sa lik'hemik'hale se phetha karolo ea bohlokoa ho khethollang thepa ea mochini le ho hanyetsa kutu ea liphaephe tse cheselitsoeng ka spiral.Likarolo tsa tšepe tse sebelisoang ka tloaelo bakeng sa liphaephe tsa spiral li kenyelletsa letoto la API 5L X, ASTM A252 limaraka tsa 2 le 3, le ASTM A139 limaraka tsa B le C. Likarolo tsena tsa tšepe li ikemiselitsoe ho latela matla a lihlahisoa le k'habone e lekanang ho netefatsa ts'ebetso e nepahetseng lits'ebetsong tse itseng.
4. Teko le tlhahlobo:
E le ho netefatsa boleng le ts'epahalo ea liphaephe tse cheselitsoeng ka spiral, bahlahisi ba khomarela mekhoa e tiileng ea tlhahlobo le tlhahlobo.Liteko tsa bohlokoa tse entsoeng li kenyelletsa tlhahlobo ea hydrostatic, tlhahlobo e sa senyeheng (joalo ka tlhahlobo ea ultrasonic kapa radiographic) le tlhahlobo ea mochini (teko ea matla, chai le phello).Liteko tsena li netefatsa hore liphaephe li finyella matla a hlokahalang, boholo le litekanyetso tsa ho lutla.
5. Ho roala holim'a sefahleho le tšireletso:
Ho sireletsa liphaephe tse cheselitsoeng ka spiral hore li se ke tsa bola le lintho tse ling tse kantle, ho na le likhetho tse fapaneng tsa ho roala holim'a metsi.Liaparo tsena li ka kenyelletsa epoxy, enamel ea mashala kapa polyethylene, har'a tse ling.Ho feta moo, mekhoa ea ts'ireletso ea cathodic joalo ka li-anode tsa sehlabelo kapa litsamaiso tsa hajoale tse khahlang li ka sebelisoa ho sireletsa liphaephe.
Ha re phethela:
Ho utloisisa lintlha tsa spiral welded pipe ho bohlokoa bakeng sa baenjiniere, batsamaisi ba merero le ba amehang mererong ea meralo ea motheo.Ka ho nahana ka bophara, botenya ba marako, kereiti ea tšepe, tlhahlobo le tšireletso ea holim'a metsi, u ka etsa bonnete ba hore phala e finyella litekanyetso tse hlokahalang tsa ts'ebetso.Ho latela melao-motheo e nepahetseng ha ho tiise feela nako e telele le ts'ireletseho ea tsamaiso ea hau ea liphaephe, empa hape ho tiisa hore ho tsamaisoa ka tšeptjoang ha metsi, likhase le lisebelisoa tse ling.Ka ho ela hloko lintlha, baenjiniere le bankakarolo ba ka fihlela sephetho se atlehileng sa projeke ha ba ntse ba kopana le litekanyetso le melaoana e hlokahalang ea indasteri.
