I-API 5L yeBanga B yeCarbon Steel Pipe Line Pipe

API 5L Grade B Carbon Steel Pipe Line Umbhobho Featured Image

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.

Intshayelelo yeMveliso

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.

Isiphakathi esineasidi: Kwimibhobho yeasidi efana nokusingqongileyo kwe-H2S, imathiriyeli yombhobho ineemfuno eziqhelekileyo zezinto zekhemikhali ezifana nekhabhoni, iphosphorus kunye nesalfure.Umgangatho weReference NACE MR0175.

Umboniso weMveliso

Isimamva unobumba

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).

Uhlobo lweMveliso

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 i-Spiral Saw yombhobho ukuya 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 negesi kunye nemizi-mveliso yokuthutha ulwelo.

I-ASTM 106 Umbhobho ubhekiselele kumbhobho wentsimbi oqengqelekayo oshushu okanye otsalwe ngokubanda (oqengqiwe) ongenamthungo.

Umbhobho we-ASTM A53 ubandakanya imibhobho yentsimbi edityanisiweyo kunye nengenamthungo yezinto ezimnyama zekhabhoni, kwaye kwezinye iimeko idiphu eshushu idiphu (igalvanized).
