Intshayelelo yePipe yeNtsimbi engenamthungo ye-ASTM A53

Umbhobho wentsimbi engenamthungo we-ASTM A53ihlelwe njenge-A53 Type S kwaye ngumbhobho wentsimbi ongenamthungo.

Yahlulwe yangamanqanaba amabini, iBanga A kunye neBanga B, kwaye ifanelekile ukusetyenziswa koomatshini kunye noxinzelelo, kunye nokusetyenziswa ngokubanzi komphunga, amanzi, igesi, kunye nomoya. Le pipe yentsimbi yipayipi yentsimbi yekhabhoni efanelekileyo kwimisebenzi yokuwelda kunye nokwenza izinto kubandakanya ukujija, ukugoba, kunye nokudibanisa iiflange.

Uluhlu lwethu lwezinto esizibonelelayo

Ukususela oko yasekwa ngo-2014,Intsimbi yeBotopiye yaba ngumthengisi ophambili wemibhobho yentsimbi yekhabhoni eMntla China, eyaziwa ngenkonzo egqwesileyo, iimveliso ezikumgangatho ophezulu, kunye nezisombululo ezibanzi.

Le nkampani inikezela ngeendidi ngeendidi zeepayipi zentsimbi yekhabhoni kunye neemveliso ezinxulumene nazo, kuquka ipayipi yentsimbi engenamthungo, i-ERW, i-LSAW, kunye ne-SSAW, kunye noluhlu olupheleleyo lwee-fittings zepayipi kunye nee-flanges. Iimveliso zayo ezikhethekileyo ziquka ii-alloys ezikumgangatho ophezulu kunye neentsimbi ezingenasici ze-austenitic, ezenzelwe ukuhlangabezana neemfuno zeeprojekthi ezahlukeneyo zepayipi.

Inkqubo yoMveliso

Imibhobho yentsimbi ye-ASTM A53 inokuba ingenamthungo okanye idityaniswe.

Indlela yokuvelisa engenamthungo (uhlobo S) kukusebenza ngentsimbi eshushu, kwaye ukuba kuyimfuneko, ukugqiba ngokubandayo kwemveliso yetyhubhu eshushu ukuze kufunyanwe imo, ubukhulu kunye neempawu ezifunekayo.

Uvavanyo lwe-Bend

Kwi-DN ≤ 50 [NPS ≤ 2], ubude obaneleyo bombhobho bufanele bukwazi ukugoba bube bandayo nge-90° bujikeleze i-mandrel esilinda, ububanzi bayo buphindwe kabini kunobubanzi obuchazwe ngaphandle bombhobho, ngaphandle kokwenza imifantu nakweyiphi na indawo.

Kabini-omelele kakhulu(XXS) umbhobho ongaphezulu kwe-DN 32 [NPS 1 1/4] akufuneki ukuba wenziwe uvavanyo lokugoba.

Uvavanyo lokuTyatya

Iityhubhu zentsimbi ezingenamthungo akufuneki zivavanywe ukuba zithe tyaba.

Ukuba kuyimfuneko ngokwesivumelwano, uvavanyo lunokwenziwa ngokwenkqubo ekwi-S1.

Uvavanyo lwe-Hydrostatic

Zonke iisayizi zemibhobho yentsimbi engenamthungo mazigcine ixabiso elithile loxinzelelo lwamanzi ngaphandle kokuvuza ubuncinane imizuzwana emi-5.

Uxinzelelo lovavanyo lweepayipi zentsimbi ezingenasiphelo lufumaneka kwiTheyibhile X2.2.

Uxinzelelo lovavanyo lwemibhobho yentsimbi edityanisiweyo nedibeneyo lufumaneka kwiTheyibhile X2.3.

Uvavanyo loMbane olungonakalisiyo

Ingasetyenziswa njengendlela eyahlukileyo endaweni yovavanyo lwe-hydrostatic.

Ubude bonke bombhobho ngamnye ongenamthungo buya kuvavanywa ngombane ongonakalisiyo ngokuhambelana nemigaqoE213, E309okanyeE570.

Ukwaleka komphezulu

Umgangatho we-ASTM A53 ucacisa iimfuno zemeko yombhobho omnyama kunye nokufakwa kwe-hot-dip galvanized coating yemibhobho yentsimbi.

Umbhobho Omnyama

Umbhobho omnyama ubhekisa kwimeko yombhobho wentsimbi ngaphandle konyango lomphezulu.

Iipayipi ezimnyama zihlala zisetyenziswa kwiindawo apho ixesha lokugcina lifutshane, indawo engqongileyo yomile kwaye ayiboli, kwaye ixabiso lihlala liphantsi kuba akukho pende.

Ukwaleka okushushu okufakwe ngesinyithi

Iipayipi ezigqunywe nge-galvanized, ezaziwa ngokuba ziipayipi ezimhlophe, zihlala zisetyenziswa kwiindawo ezifumileyo okanye ezirhabaxa.

I-zinc ekwi-zinc coating ingaba loluphi na uhlobo lwe-zinc kwi-ASTM B6.

Umbhobho we-galvanized mawungabi nazindawo zingagqunywanga, ama-blister, ii-flux deposits, kunye neengcola ezinkulu. Amaqhuma, ii-projections, ii-globules, okanye ii-deposits ezinzima ze-zinc eziya kuphazamisana nokusetyenziswa okucwangcisiweyo kwezinto aziyi kuvunyelwa.

Umxholo weZinc ongaphantsi kwe-0.55 kg/m² [1.8 oz/ft²].

Ezinye Iingubo

Ukongeza kwimibhobho emnyama kunye ne-galvanized coating, iintlobo eziqhelekileyo zokugquma ziqukaipeyinti, 3LPE, I-FBE, njl. Uhlobo olufanelekileyo lokugquma lunokukhethwa ngokweemfuno ezithile zendawo yokusebenza.
