SSAW Spiral Iwweldjat x42 Pajp ta 'l-Azzar
Karatteristika
-
Il-pajp iwweldjat b'spirali huwa magħmul billi tirrumbla l-istrixxa tal-azzar ta 'azzar strutturali b'livell baxx ta' karbonju jew azzar strutturali b'liga baxxa f'pajp vojt skont ċertu angolu tal-helix (imsejjaħ angolu li jifforma), u mbagħad iwweldja l-ġonot tal-pajpijiet.Jista 'jipproduċi pajpijiet ta' l-azzar b'dijametru kbir minn strixxi dojoq ta 'l-azzar.

(1) pajpijiet ta 'l-azzar b'dijametri differenti jistgħu jiġu prodotti bl-użu ta' azzar ta 'strixxa bl-istess wisa', speċjalment pajpijiet ta 'l-azzar b'dijametru kbir jistgħu jiġu prodotti minn azzar ta' strixxa dejqa.
(2) Taħt l-istess kundizzjoni ta 'pressjoni, l-istress ta' weldjatura spirali hija iżgħar minn dik ta 'weldjatura dritta, li hija 75% ~ 90% ta' dik ta 'pajp iwweldjat dritta, għalhekk tista' ġġorr pressjoni akbar.Meta mqabbel mal-pajp iwweldjat dritta bl-istess dijametru ta 'barra, il-ħxuna tal-ħajt tista' titnaqqas b'10% ~ 25% taħt l-istess pressjoni.
(3) Id-dimensjonijiet huma preċiżi, ġeneralment it-tolleranza tad-dijametru hija inqas minn 0.12%, id-deflessjoni hija inqas minn 1/2000, u l-ovalità hija inqas minn 1%, għalhekk il-proċeduri tad-daqs u l-iddrittar jistgħu ġeneralment jitħallew barra.
(4) Produzzjoni kontinwa hija possibbli.Fit-teorija, jistgħu jiġu prodotti pajpijiet tal-azzar infinitament twal.It-telf tar-ras tat-tqattigħ u d-denb huwa żgħir, u r-rata ta 'utilizzazzjoni tal-metall tista' tiżdied b'6% ~ 8%.(5) Meta mqabbel mal-pajp iwweldjat dritta, huwa flessibbli fl-operazzjoni, u konvenjenti fil-bdil tal-varjetajiet u l-aġġustament.
(6) Piż ħafif tat-tagħmir u inqas investiment inizjali.Jista 'jsir f'unitajiet mobbli tat-tip ta' karru biex jipproduċu direttament pajpijiet iwweldjati fis-sit tal-kostruzzjoni fejn jitqiegħdu l-pipelines.
(7) Huwa faċli li tirrealizza l-mekkanizzazzjoni u l-awtomazzjoni.
Pajp iwweldjat spirali jintuża prinċipalment fl-inġinerija tal-ilma tal-vit, industrija petrokimika, industrija kimika, industrija tal-enerġija elettrika, irrigazzjoni agrikola u kostruzzjoni urbana fiċ-Ċina.Użat għat-trasport likwidu: provvista ta 'ilma u drenaġġ.Għat-trasport tal-gass: gass tal-faħam, fwar u gass tal-pitrolju likwifikat.Użat bħala struttura: użat bħala pajp tas-sewqan tal-pil u pont;Pajpijiet għal baċiri, toroq u strutturi tal-bini, eċċ.
Applikazzjoni
Bħala intrapriżi ewlenin tal-industrija tal-materjali tal-metall taċ-Ċina, il-kummerċ nazzjonali tal-azzar u l-loġistika "Mit intrapriża ta 'bona fede", intrapriżi tal-kummerċ tal-azzar taċ-Ċina, "Top 100 intrapriża privata f'Shanghai". ) jieħu l-"Integrità, Prattika, Innovazzjoni, Win-Win" bħala l-uniku prinċipju ta 'operazzjoni tiegħu, dejjem jippersistu fit-tqegħid tad-domanda tal-klijent fl-ewwel post.
