API 5L: Muyero uyu wakapihwa neAmerican Petroleum Institute uye unotsanangura zvinodiwa pakugadzira mazinga maviri ezvigadzirwa (PSL 1 nePSL 2) emapombi esimbi asina musono uye akasungirirwa kuti ashandiswe mumasisitimu ekufambisa mapaipi mumaindasitiri epetroleum negasi rechisikigo.

ASTM A252: Muyero uyu wakapihwa neAmerican Society for Testing and Materials uye unosanganisira mapaipi esimbi emadziro ane chimiro che cylindrical umo silinda yesimbi inoshanda sechinhu chinotakurwa mutoro zvachose kana segoko rekugadzira mapaipi ekongiri akaiswa panzvimbo.

Kuputira pamusoro peSSAW Spiral Welded Steel Pipe

Kupfeka kwePolyethylene ine mativi matatu (3LPE):Kuputira uku kunosanganisira epoxy layer ine fusion-bonded, glue layer, uye polyethylene layer. Kunodzivirira ngura zvakanaka uye kunowanzo shandiswa kumapaipi munzvimbo dzakaoma.

Kuputira kweFusion-Bonded Epoxy (FBE):Kuputira kweFBE kunoita kuti pave nekudzivirira makemikari zvakanaka uye kwakakodzera kushandiswa pamusoro pevhu uye pasi pevhu.

Kugadzira simbi:Maitiro ekugadzira simbi anosanganisira kuisa chifukidziro chezinc chinodzivirira papombi yesimbi kuti isapararire ngura. Pombi yesimbi inonyudzwa mubhavhu rezinc yakanyungudutswa, iyo inoumba chisungo chesimbi nesimbi, zvichiita kuti chifukidziro chigare kwenguva refu uye chisapararire ngura. Kugadzira simbi inopisa kwakakodzera kushandiswa mukati nekunze uye kunopa dziviriro yakanaka kubva kungura nekuora.

Mapombi eSimbi yeCarbon Welded Spiral

Kutakura Oiri neGasi:Inoshandiswa zvakanyanya kutakura mafuta asina kucheneswa, gasi rechisikigo, nezvimwe zvigadzirwa zvepeturu munzvimbo refu.
Kugoverwa kweMvura:Yakakodzera mapaipi emvura nekuda kwekugara kwenguva refu uye kuramba kwayo ngura.
Mashandisirwo Ekuvaka:Ndakashanda mukuvaka kuti nditsigire zvivakwa, zvakaita semabhiriji, zvivakwa, uye mamwe mapurojekiti ezvivakwa.

Kuongorora uye Kudzora Hunhu hweMapaipi eSimbi yeKabhoni Yakasungirirwa neSpiral

Kuongorora Kwemativi:Mapaipi anoongororwa kuti anoenderana nedhayamita, ukobvu hwemadziro, uye urefu.
Kuedzwa kweMichina:Mapaipi anoedzwa kuti aone kana akasimba, kuti anobuda sei, kuti akareba sei, uye kuti akasimba sei kuitira kuti ave nechokwadi chekuti anosangana nezvinodiwa.

Kuedzwa Kusingakuvadzi:

Kuedzwa kweUltrasonic (UT): Kunoshandiswa kuona zvikanganiso zvemukati mumusungo we weld.
Kuedzwa kweHydrostatic: Pombi yega yega inoedzwa hydrostatic pressure kuti ive nechokwadi chekuti inogona kubata pressure dziri kushanda pasina kubuda mvura.
