API 5L PSL1 uye PSL2 Misiyano yeSimbi Line Pipe

API 5L mutsetse pombi (Seamless uye welded pombi) yemagiredhi ese ane PSL1 uye PSL2 maviri echigadzirwa zvakatemwa, iwo akasiyana pakuumbwa kwemakemikari, maitiro ekugadzira, simba remuchina, kupisa kupisa, marekodhi ebvunzo, traceability nezvimwe.

Mitsetse mapaipi muAPI 5L PSL2 yakakwirira kupfuura PSL1

a. PSL izita pfupi rechigadzirwa mwero level. Chigadzirwa chiyero chemutsetse wepombi ine PSL1 uye PSL2, zvakare isu tinogona kutaura mhando yemhando yakakamurwa muPSL1 nePSL2. PSL2 yakakwira kupfuura PSL1, kwete chete chiyero chekuongorora chakasiyana, zvakare makemikari pfuma, mechanical simba zviyero zvakasiyana. Saka kana ukaisa iyo API 5L mutsetse pombi, panofanirwa kutaurwa zvakajeka kune saizi, mamakisi aya akajairwa, zvakare anofanirwa kujekesa chiyero chekugadzira, PSL1 kana PSL2.
PSL2 yakanyanya kuomarara kupfuura PSL1 pane makemikari zvivakwa, tensile simba, isinga paradza bvunzo, uye maitiro ekuedza.

Yakasiyana maitiro ekuedza maitiro ePSL1 uye PSL2

b. API 5L PSL1 simbi mutsetse pombi haidiwe kuita bvunzo yekukanganisa.
Kune API 5L PSL2 simbi mutsetse pombi, kunze kweGiredhi X80, mamwe magiredhi eAPI 5L mutsetse wepombi aida bvunzo yekukanganisa patembiricha ye0℃. Avhareji kukosha kweAkv: longitudinal direction≥41J, transverse direction≥27J.
Ye API 5L Giredhi X80 PSL2 mutsetse pombi, pa 0 ℃ kune ese saizi, kukanganisa kuyedza iyo Akv avhareji kukosha: longitudinal direction≥101J, transverse direction≥68J.

Yakasiyana hydraulic bvunzo yeAPI 5L mutsetse pombi muPSL1 uye PSL2

c. Ye API 5L PSL2 mutsetse wepombi ichaita iyo hydraulic bvunzo papombi imwe neimwe, uye mune API chiyero yakatarwa isingabvumire kuve neNon-destructive test kutsiva iyo hydraulic test, uyuwo musiyano mukuru pakati peChinese chiyero uye API 5L chiyero. YePSL1 haidiwe Kusaparadza bvunzo, yePSL2 ichaita iyo Inoparadza bvunzo yepombi imwe neimwe.

Yakasiyana makemikari kuumbwa kweAPI 5L mutsetse pombi muPSL1 uye PSL2

d. Kemikari kuumbwa uye simba remagetsi rakasiyanawo pakati pe API 5L PSL1 mutsara pombi uye API 5L PSL2 mutsetse pombi. Zvekutsanangurwa kwakadzama sezviri pazasi. API 5L PSL2 ine zvirambidzo zvine kabhoni yakaenzana yezvinhu, uko kune kabhoni misa chikamu chikuru kupfuura 0.12%, uye yakaenzana kana isingasviki 0.12%. Yakasiyana CEQ ichashandiswa. Yemutsetse pombi muPSL2 tensile simba ine miganho yakakura.
