Ukutsalwa okubandayo/Kushushu Ukuqengqeleka/Kubandayo Ukuqengqeleka kwaSangqa ngaphandle komthungo wentsimbi/umbhobho ochanekileyo
Inkcazelo emfutshane:
I-API 5L yeBanga B ipayipi yensimbi ngumbhobho webakala oqhelekileyo wokuthuthwa kwemibhobho ye-oyile kunye negesi.Ikwabizwa ngokuba ngumbhobho we-L245, ekubhekiselwa kuwo kwi-ISO 3183, ebizwa ngokuba yi-245 Mpa ye-245 Mpa (355,000 Psi).
Izinto ezilinganayo ze-ASTM A106 B okanye i-ASTM A53 B enexabiso elifanayo ekubunjweni kweekhemikhali, iimpawu zomatshini kunye nokusetyenziswa.
I-API 5L B igubungela i-PSL1, i-PSL2, inkonzo emuncu kwimibhobho yonxweme nangaphandle konxweme.Iintlobo zokwenziwa zibandakanya i-seamless kunye ne-welded.
Ngelixa sisebenzisa intanda-bulumko yenkampani “ejolise kuMthengi”, indlela yolawulo ekumgangatho ophezulu efunwayo, imveliso yokuvelisa izinto ezintsha kunye nabasebenzi be-R&D eyomeleleyo, sihlala sihambisa iimpahla ezikumgangatho ophezulu, izisombululo ezigqwesileyo kunye namaxabiso ashushu okuthengisa eCold Drawn/Hot Rolled/I-Cold Rolled Roundless Seamless Precision Steel Tube/Pipe, Ngaphandle koko, inkampani yethu inamathela kumgangatho ophezulu kunye neendleko ezifikelelekayo, kwaye sinikezela ngeenkampani ezinkulu ze-OEM kwiimpawu ezininzi ezidumileyo.

I-PSL1, i-PSL2 kunye ne-Acidic Media Types.
Ngokuqhelekileyo kusetyenziswa i-PSL1, elingana ne-ASTM A106 B kunye ne-A53 B.
I-PSL2 ngumbhobho wodidi oluchaziweyo oluphezulu oneemfuno ezingqongqo zokomelela kweekhemikhali kunye noomatshini.I-PSL2 ifuna iindlela ezininzi zovavanyo ezifana novavanyo olungonakalisi, uvavanyo lwempembelelo ye-CVN, i-DWT, njl.
I-API 5L B PSL2 imelwe yi-API 5L BN/Q/R/M.
Umbindi weAcidic: Kwimibhobho yeasidi efana nokusingqongileyo kwe-H2S, imathiriyeli yombhobho ineemfuno eziqhelekileyo zezinto zekhemikhali ezifana nekhabhoni, iphosphorus kunye nesalfure.Umgangatho weReference NACE MR0175.
Oonobumba abasisimamva baxela iimeko zokuhanjiswa kombhobho:
R: Xa uqengqeleka.
N: ukulungelelanisa ukuqengqeleka, ukubunjwa kwesiqhelo, ukulungelelanisa.
Umbuzo: Ukunciphisa kunye nokunciphisa.
M: Ukuqengqeleka kwe-Thermomechanical okanye ukwenza i-thermomechanical.
S: Isixhobo esimuncu esinetyhubhu ye-PSL2 ye-NS, QS, MS, umz. API 5L Grade B NS, API 5L B QS.
Iintlobo ezingenamthungo kunye ne-welded (RW, LSAW, SSAW/HSAW).
Isimbo esingenamthungo:kubandakanywa imibhobho engenamthungo eshushu-isolwe ngaphezulu kwe-intshi ezi-3, imibhobho epholileyo eqengqelekayo engaphantsi kwe-intshi ezi-3.
Uhlobo lwe-RW Welding:I-Resistance Welding, ilungele imibhobho ukuya kuma-intshi angama-24.
Uhlobo lwe-Welding ye-Arc ethe tye:I-longitudinal segmented arc welding, ilungele imibhobho enobubanzi obungaphandle obuyi-intshi ezingama-20 ukuya kwi-intshi ezingama-48.I-LSAW ikwabizwa ngokuba yi-JCOE, nto leyo ethetha ukwenza iimilo ukusuka kwimilo engu-J, enobume buka-C, emile okwe-O, emva koko imibhobho eyandiswa ngokubanda.
SSAW/HSAW Uhlobo:I-Spiral Submerged Arc Welding okanye iSpiral Saw yombhobho ukuya kuthi ga kwi-100″ OD.
I-API 5L iBanga B, i-ASTM A106 iBanga B kunye ne-A53 iBanga B, ezi zixhobo zintathu zezona zinto zisetyenziswa ngokuqhelekileyo kulwakhiwo lwemibhobho okanye i-oyile kunye negesi kunye namashishini okuthutha ulwelo.
I-ASTM 106 Umbhobho ubhekisa kumbhobho wentsimbi wekhabhoni ongenamthungo okanye oshushu okanye otsalwe ngokubanda (oqengqiwe).
Umbhobho we-ASTM A53 ubandakanya imibhobho yentsimbi edityanisiweyo kunye nengenamthungo yezinto ezimnyama zekhabhoni, kwaye kwezinye iimeko idiphu eshushu idiphu (igalvanized).
