Spiral Welded Steel Pipes Mataurirwo uye Maitiro

Zvinodiwa:Kunze dhayamita 219mm kusvika 3000mm; Ukobvu sch40, sch80, sch160; Kureba 5.8m, 6m, 12m kana customized

Magiredhi:Mapaipi eSSAW anogona kugadzirwa mumagiredhi akasiyana, kusanganisira API 5L yakatarwa seGiredhi B, X42, X52, X60, X65, X70, uye X80.

Maitiro:Inowanzo gadzirwa zvinoenderana nezviyero zvakaita seAPI 5L, ASTM A252, kana zvimwe zvinoenderana zvinoenderana nekushandiswa.

API 5L: Iyi chiyero inopihwa neAmerican Petroleum Institute uye inotsanangura zvinodikanwa pakugadzirwa kwezvikamu zviviri zvechigadzirwa (PSL 1 uye PSL 2) yemapombi esimbi asina musono uye akaiswa welded kuti ashandiswe mumapombi ekufambisa masisitimu mupetroleum uye gasi rechisikigo maindasitiri. .

ASTM A252: Iyi chiyero inopihwa neAmerican Society for Testing and Materials uye inovhara zita remadziro cylindrical simbi pombi mirwi umo silinda yesimbi inoshanda senhengo yekusingaperi inotakura mutoro kana segoko rekugadzira akakanda-mu-nzvimbo makongiri mirwi.

SSAW Spiral Welded Steel Pipe Surface Coating

3-Layer Polyethylene (3LPE) Coating:Uku kupfekedza kunosanganisira fusion-bonded epoxy layer, adhesive layer, uye polyethylene layer. Iyo inopa yakanakisa corrosion kuramba uye inowanzoshandiswa kune mapaipi munzvimbo dzakaoma.

Fusion-Bonded Epoxy (FBE) Coating:FBE coating inopa yakanaka makemikari kuramba uye inokodzera zvese zviri pamusoro-pasi uye pasi pevhu kunyorera.

Galvanizing:Iyo galvanizing process inosanganisira kuisa inodzivirira zinc coating kune pombi yesimbi kuti ipe corrosion resistance. Spiral weld simbi pombi inonyudzwa mubhavhu rezinc yakanyungudutswa, iyo inoumba chisungo chesimbi nesimbi, ichigadzira jira rinogara uye risingaparare. Kupisa-dip galvanizing kwakakodzera kune zvese zvemukati uye zvekunze kunyorera uye inopa yakanakisa dziviriro kubva kune ngura uye ngura.

Spiral Welded Carbon Steel Pipes Applications

Kufambiswa kweOiri neGasi:Inoshandiswa zvakanyanya kutakura crude oil, gasi rechisikigo, uye zvimwe zvigadzirwa zvepetroleum nzendo refu.
Kugoverwa kwemvura:Inokodzera mapaipi emvura nekuda kwekugara kwavo uye kuramba kune ngura.
Structural Applications:Kushandirwa mukuvaka kutsigirwa kwezvimiro, senge mumabhiriji, zvivakwa, uye zvimwe zvirongwa zvezvivakwa.

Spiral Welded Carbon Steel Pipes Kuongorora uye Kudzora Kwemhando

Dimensional Inspection:Mapombi anotariswa kuti anoenderana here nedhayamita, ukobvu hwemadziro, uye kureba.
Mechanical Testing:Mapombi anoedzwa kusimba kwekusimba, goho simba, kurebesa, uye kuoma kuti ave nechokwadi chekuti anosangana nezvinodiwa.

Kuedza Kusina Kuparadza:

Ultrasonic Testing (UT): Inoshandiswa kuona kukanganisa kwemukati mune weld seam.
Hydrostatic Testing: Yese pombi inoiswa pasi pe hydrostatic pressure kuyedzwa kuti ive nechokwadi chekuti inokwanisa kubata madhiri ekushanda pasina kubuda.
