Choj prestressed yas corrugated pipeline ntau lawm kab thiab grouting yeeb nkab ntau lawm kab raug xa mus rau cov neeg muas zaub nyob rau hauv Chengdu,
Qingdao Cuishi yas machinery manufacturing yas hau yas pe txoj kev loj yas yeeb nkab Choj prestressed yas bellows los ntawm steel stranded qhob nrog choj tsev prestressed yas bellows
Cov khoom no tsuas yog siv rau hauv nroog, kev tiv thaiv txoj kab nqes, kev kub ceev choj prestress nro yas bellows, prestressed corrugated choj yeeb nkab, nyob rau hauv lub sij hawm pouring los tiv thaiv cov hlau strand los ntawm cov pa phem, los xyuas kom meej nro nroPrestressed yas raj lub ntsiab specifications: 50 55 60 65 70 75 80 85 90 95 100 105 110 115 120mm phab ntsa thickness 2.2-3cm
Prestressed yas bellows yog ib lub phab ntsa bellows extruded los ntawm cov yas extruder los ntawm high-density polyethylene (HDPE) rau post-tensioned prestressed qhob vaj tse raws li ib tug perforated yeeb nkab nrog prestressed tav.Nws yog ib qho kev xaiv zoo tshaj plaws rau thawj cov hlau bellows hauv choj thiab kev tsim vaj tsev.Plastic bellows tau muab faib ua ob pawg: cov kav dej puag ncig thiab cov kav dej tiaj tus, uas tau txuas nrog kev siv tiag tiag los ntawm ntau hom yas txuas.Cov khoom siv raw rau cov yas yas prestressed yog HDPE.Nws cov corrosion kuj zoo dua li cov hlau, tsis ntshai ntawm acid thiab alkali corrosion, nws tsis corrode nws tus kheej, thiab muaj peev xwm tiv thaiv cov prestressed tav los ntawm corrosion.

Yas bellows raws li prestressed post-tensioning txoj kev ntawm cov khoom ntxeem tau yog ib qho tseem ceeb ntawm lub prestressed system, rau lub sij hawm ntev prestressed engineering siv hlau bellows raws li ib tug pore khoom, thiaj li yuav kov yeej cov shortcomings ntawm hlau bellows pluag sealing, yooj yim puas, yooj yim rau xeb, kev sib txhuam loj, tab sis kuj txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws yog qhov zoo tshaj plaws kom siv cov polyethylene lossis polypropylene ua los ntawm cov yas hauv qab ua cov khoom hloov pauv nrog kev sib koom ua ke tom qab tensioning txoj kev los txhim kho lub neej. ntawm tus qauv
