Delivery Conditions
Zvichienderana nemamiriro ekutumira uye PSL level, iyo X60 inogona kuiswa sezvizvi:
PSL1: x60 kana L415;
PSL2: X60N, X60Q, X60M kana L415N, L415Q, L415M.
N: Inoratidza normalization yezvinhu.Nekupisa simbi kune imwe tembiricha inoteverwa nekutonhodzwa kwemhepo.Kuvandudza iyo microstructure uye michina zvivakwa zvesimbi uye kuwedzera kuoma kwayo uye kusimba.
Q: Inomirira Kudzima uye Kupisa.Kupisa simbi nekuipisa kusvika kune imwe tembiricha, kuitonhodza nekukurumidza, uyezve kudziisa kune tembiricha yakaderera.Kuti uwane chiyero chezvakananga zvemakanika zvivakwa, senge simba repamusoro uye kuoma.

API 5L X60 Manufacturing Process
Inogamuchirwa simbi chubhu yekugadzira maitiro eX60
Kana iwe ukaona izvi zvipfupiso zvakaoma kunzwisisa, tarisa yedu kuunganidzwa kwezvinyorwa pazvakajairika zvipfupiso nokuda simbi pombi.
Zvakanakira zveSAWL (LSAW)
Kana iwe uchida hombe dhayamita gobvu madziro simbi pombi, yekutanga sarudzo ndeyeSAWL (LSAW) pombi yesimbi.LSAW simbi pombi inogona kugadzirwa muhukuru kusvika 1500mm dhayamita uye 80mm mumadziro ukobvu, iyo inonyatsokwanisa kuita zvinodiwa zvemapaipi marefu ezvirongwa zvakakura.
Uye zvakare, panguva yekugadzira, LSAW simbi pombi inotora kaviri-mativi akanyura arc welding (DSAW) process, iyo inovimbisa kunaka kweiyo weld seam.
API 5L X60 Chemical Kuumbwa
PSL1 iri nyore kwazvo pane PSL2 maererano nemakemikari ekuumbwa, mechanical zvivakwa, uye zvimwe zvinodiwa.
Izvi zvinodaroPSL1inomiririra mwero mwero wemhando yepombi simbi pombi, nepoPSL2inogona kuoneka seyakakwidziridzwa vhezheni yePSL1, iyo inopa mamwe epamberi maratidziro uye kuomarara kwemhando yekudzora.
Kemikari Inoumbwa yePSL 1 Pipe ine t ≤ 25.0 mm (0.984 mukati.)
Kemikari Inoumbwa yePSL 2 Pipe ine t ≤ 25.0 mm (0.984 mukati.)
Ye PSL2 simbi pombi zvigadzirwa akaongororwa neKabhoni yemukati ye ≤0.12%, iyo kabhoni yakaenzana CEpcminogona kuverengerwa uchishandisa inotevera formula:
CEpcm= C + Si/30 + Mn/20 + Cu/20 + Ni/60 + Cr/20 + Mo/15 + V/15 + 5B
Ye PSL2 simbi pombi zvigadzirwa akaongororwa neKabhoni yemukati > 0.12%, iyo kabhoni yakaenzana CEllwinogona kuverengerwa uchishandisa formula iri pazasi:
CEllw= C + Mn/6 + (Cr + Mo + V)/5 + (Ni +Cu)/15
Kemikari Inoumbwa ine t ＞ 25.0 mm (0.984 mukati.)
Ichagadziriswa nekutaurirana uye kuchinjwa kuti ive yakakodzera kuumbwa zvichienderana nemakemikari anodiwa pamusoro apa.
