Li-groove joints li qapiloe khale. Ntoeng ea Pele ea Lefatše, li ne li sebelisetsoa ho kenya liphaephe tse nang le motsoako o tukang, o neng o sebelisoa ka li-flamethrowers. Ho tloha ka nako eo, li 'nile tsa sebelisoa mefuteng e mengata ea mekhoa ea khotso moo ho hlokahalang likhokahano tse tšepahalang le tsa boleng bo phahameng.
Ha u kenya pipeline, tlhokomelo e khethehileng e lefshoa ho li-connections. Ho tšoarella le ho tšepahala ha tsamaiso, bokhoni ba ho mamella meroalo e phahameng, le boiketlo ba tlhokomelo e latelang e itšetlehile ka tsona. Ka nako e telele, likhokahano tse nang le likhoele le welding li ne li sebelisoa e le mekhoa ea mantlha ea ho kenya. Kajeno, maqhama a grooved - li-clamps tse senyehang tse nang le molala o tiisang - a ntse a tsebahala. 'Mele oa clamp e joalo o entsoe ka tšepe ea ductile kapa carbon steel,' me ho kenngoa ho entsoe ka thepa e sa keneleng mocheso ea rabara.
Ho itšetlehile ka meroalo, li-couplings li entsoe ka tšepe e entsoeng ka tšepe, tšepe ea carbon le lisebelisoa tse ling tse tšoanang. Ho kopanya ho na le li-halves tse peli le "relastic polymer O-ring" (cuff). Liphaephe tse nang le li-grooves (li-grooves) li kopantsoe ka letoto, li kopane ho kopana, 'me ntlha ea ho fetoha e koahetsoe ka tiiso ea o-ring.
Phetolelong ea mantlha, li-grooves tsa li-groove couplings li ne li khaotsoe ka li-milling cutters. E ne e le mokhoa o rarahaneng le o sa thabiseng. Matsatsing ana, ho sebelisoa sesebelisoa se khethehileng ho etsa li-grooves - li-roller groovers. Li fapane ka mokhoa oa ho khanna (manual kapa hydraulic) le bophara ba liphaephe tseo ba khonang ho sebetsa ka tsona.

Mefuta ea li-groove fittings
Molao-motheo oa li-fittings tsa grooved o sebelisetsoa ho kenya ts'ebetsong mefuta e mengata ea mesebetsi nakong ea ho kenya liphaephe. Ho na le mefuta e 'maloa ea lisebelisoa tse joalo:
• ho kopanya - phetolelo ea khale e etselitsoeng ho kopanya likarolo tse peli tsa liphaephe tsa bophara bo lekanang;
• setsoe - ntho e potolohang bakeng sa pipeline e nang le moeli o bōpehileng ka ho khetheha o lumellang ho kenya clamp habonolo;
• li-plug - likarolo tse u lumellang hore u koale ka nakoana kapa ka ho sa feleng lekala la liphaephe kapa u netefatse hore ho amana ha groovelock ka khoele;
• li-adapter tsa concentric - li u lumella hore u kopanye phala ea bophara bo nyane ka ho lokisa likhoele;
• slip-on flange - e netefatsa phetoho ea tsamaiso ea groove ho tsamaiso ea flange;
• lisebelisoa tse ling - mehlala e mengata e etselitsoe ho etsa li-compact bends ka ho toba ho kopane.
Ho na le li-couplings tse thata le tse tenyetsehang tsa grooved. Ea pele e eketsehile matla a bapisoang le weld. Likhetho tse feto-fetohang li u lumella ho lefella likhaello tse nyane tsa angular le ho mamella khatello le khatello ea maikutlo. Lisebelisoa tse entsoeng ka grooved li sebelisetsoa liphaephe tse bophara ba 25-300 mm, kahoo ho bonolo ho khetha li-clamps bakeng sa liphaephe bakeng sa merero e mengata e fapaneng. Ha u reka li-fittings, hoa hlokahala ho hlakisa mefuta e mengata ea li-diameter tse sebetsang tseo sehlahisoa se reretsoeng ho se etsa. Sena se tla thusa ho fumana hore na khetho e itseng e nepahetse ho uena.
