Izinzuzo Welded Cold Formed Welded Structural Pipes

Izinzuzo of ashiselwe Cold Formed ashiselwe Amapayipi Structural Okufakiwe Isithombe

Incazelo emfushane:

Lokhu kucaciswa kuhlanganisa amabanga amahlanu wepayipi lensimbi elihlanganisiwe (arc) elishiselwe i-helical-seam.Ipayipi lenzelwe ukudlulisa uketshezi, igesi noma umhwamuko.

Ngemigqa engu-13 yokukhiqiza yepayipi lensimbi elivunguzayo, iCangzhou Spiral Steel pipes group Co., Ltd. iyakwazi ukwenza amapayipi ensimbi ane-helical-seam anobubanzi obungaphandle ukusuka ku-219mm kuya ku-3500mm nogqinsi olufika ku-25.4mm.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Emikhakheni yezokwakha nokukhiqiza, ukukhethwa kwezinto zokushisela nezindlela kudlala indima ebalulekile ekuqedeni ngempumelelo noma iyiphi iphrojekthi.Enye impahla enjalo eye yaduma eminyakeni yamuva nje ipayipi lesakhiwo elihlanganisiwe elibandayo.Lo mkhiqizo omusha unikeza izinzuzo ezimbalwa ngaphezu kwamapayipi endabuko angenamthungo noma ashiselwe, ikakhulukazi amapayipi othungelwano oluyindilinga.

Kuyabanda kwakheka ashiselwe isakhiwoipayipi lakhiwe ngenqubo yokwakheka okubandayo, okubandakanya ukugoba nokwenza amakhoyili ensimbi abe yisimo esifunwayo.Umphumela uba ipayipi eliqinile neliqinile, nokho lingasindi futhi kulula ukulisebenzisa.Ukwengeza, inqubo yokubumba ebandayo iqinisekisa ukuthi ipayipi igcina ubuqotho bayo besakhiwo kanye nokunemba kobukhulu, okwenza kube kuhle ekusetshenzisweni kokushisela.

Ukuhlolwa kwe-Hydrostatic

Ubude bepayipi ngalinye kufanele buhlolwe ngumenzi kumfutho we-hydrostatic ozokhiqiza odongeni lwamapayipi ingcindezi engekho ngaphansi kuka-60% wamandla esivuno amancane ashiwo ekamelweni lokushisa.Ingcindezi izonqunywa yi-equation elandelayo:
P=2St/D

Ukwehluka Okuvumelekile Kwesisindo Nobukhulu

Ubude bepayipi ngalinye buzokalwa ngokuhlukene futhi isisindo salo akumele sihluke ngaphezu kuka-10% ngaphezulu noma u-5.5% ngaphansi kwesisindo salo esicatshangelwayo, kubalwe kusetshenziswa ubude balo nesisindo salo ngobude beyunithi ngayinye.
Idayamitha yangaphandle akumele ihluke ngaphezu kuka-±1% ukusuka kububanzi obukhethekile obushiwo bengaphandle.
Ukujiya kodonga kunoma iyiphi indawo akufanele kube ngaphezu kuka-12.5% ngaphansi kogqinsi olushiwo.

Ubude

Ubude obungahleliwe obubodwa: 16 kuya ku-25ft(4.88 kuya ku-7.62m)
Ubude obuphindwe kabili obungahleliwe: ngaphezulu kwama-25ft kuya ku-35ft(7.62 kuya ku-10.67m)
Ubude obufanayo: ukuhluka okuvumelekile ±1in

Iyaphela

Izinqwaba zamapayipi zizonikezwa iziphetho ezicacile, futhi ama-burrs ekugcineni azosuswa.
Lapho ukuphela kwepayipi okushiwo ukuthi kube yi-bevel iphela, i-engeli izoba ngu-30 kuya ku-35 degree

Enye yezinzuzo eziyinhloko zesakhiwo esihlanganisiwe esibandaipayipi lokushiselaamandla ayo okumelana namazinga okushisa aphezulu nezingcindezi.Ngokungafani namapayipi endabuko, asengozini yokugqwala nezinye izinhlobo zokuwohloka, amapayipi akhiwe ngendlela ebandayo akhiwe ukuze amelane nobunzima bokushisela nezinye izinqubo zezimboni.Lokhu kubenza balungele ukusetshenziswa ezinhlelweni ezihlukahlukene kusukela ekwakhiweni kwezakhiwo kuya kumaphrojekthi wengqalasizinda.

Enye inzuzo yepayipi lesakhiwo elihlanganisiwe elibandayo liyindleko ephumelelayo.Inqubo ebandayo yokwakha ingakhiqiza amapayipi ngobukhulu obuhlukahlukene kanye nokuma, ukunciphisa isidingo sezinqubo ezibizayo zokuphonsa kanye nezinqubo zomshini.Lokhu kwenza umkhiqizo uthengeke kakhulu futhi uthembekile njengepayipi elingenamthungo noma elishiselwe.Ukwengeza, imvelo engasindi yepayipi eyenziwe ngamakhaza yenza ukuthutha nokufakwa kube lula futhi kungabizi kakhulu, kuqhubeke nokwandisa ukukhanga kwayo.

Amashubhu e-Spiral seam azuza ikakhulukazi enqubweni yokwakheka okubandayo.Amandla emvelo kanye nokuguquguquka kwamashubhu akheke abandayo awenza alungele ukudala amajoyinti azungezayo aqinile futhi angavuzi.Lokhu kubenza babe ukukhetha okuhle kakhulu kwezinhlelo zokusebenza ezifana nezinhlelo zokudonsa amanzi ngaphansi komhlaba, izintambo zamanzi kanye nezinhlelo zokunisela ngezolimo.Ukwengeza, indawo ebushelelezi yamapayipi akhiwe ngokubanda inciphisa ingozi yokungqubuzana nokuguga, inwebe impilo yamapayipi futhi inciphise isidingo sokunakekelwa nokulungiswa.

Sekukonke, ipayipi lesakhiwo elishiselwe elibandayo linikeza izinzuzo eziningi ezilenza libe yisinqumo esihle kakhulu sezinhlelo zokushisela, ikakhulukazi ipayipi lomthungo elivunguzayo.Amandla abo, ukuqina kanye nokusebenza kahle kwezindleko kubenza babe ukukhetha okukhangayo ezimbonini eziningi, kusukela kwezokwakha kuye kwezokukhiqiza.Njengoba isidingo sekhwalithi ephezulu, izinto ezinokwethenjelwa ziqhubeka zikhula, ipayipi lesakhiwo elihlanganisiwe elibandayo lizoba ukukhetha okuthandwa kakhulu kwezicelo zokushisela.
