API 5L:Mutemo uyu wakagadzwa neAmerican Petroleum Institute uye unotsanangura zvinodiwa pakugadzira pombi dzemuchina dzinoshandiswa kutakura mafuta, gasi, nezvimwe zvigadzirwa zvepeturu. Kutevedzera API 5L kunoita kuti pombi yesimbi yeLSAW isvike pamhando inodiwa uye zvinodiwa pakushanda kwayo muindasitiri yemafuta negasi.
ASTM A53:ASTM A53 imhando yakajairwa yemapaipi, simbi, nhema uye inopisa, yakaputirwa ne zinc, yakasungirirwa, uye isina musono. Kutevedzera ASTM A53 kunoita kuti pombi yesimbi yeLSAW isvike pazvinodiwa pakushandiswa mumashandisirwo emakanika uye ekumanikidza, pamwe nekushandiswa kwakajairika.
ASTM A252:tsananguro yakajairwa yemapombi esimbi akasungirirwa uye asina musono. Kana zvasvika kumapombi esimbi eLSAW (Longitudinal Submerged Arc Welded), kutevedzera ASTM A252 kwakakosha zvikuru pamashandisirwo anosanganisira mapombi esimbi anoshandiswa mukuvaka uye mapurojekiti ekutsigira chivakwa. ASTM A252 inotsanangura zvinodiwa zvehunyanzvi zvemapombi esimbi, kusanganisira saizi, hunhu hwemakanika, uye maitiro ekuyedza.
Mapaipi esimbi eLSAW anotevedzera ASTM A252 akagadzirirwa kusangana nezvinodiwa zvekushandiswa mukuisa mapombi, zvakaita sekuvaka nheyo, zvivakwa zvemugungwa, kuvaka mabhiriji, nemamwe mapurojekiti einjiniya. Kutevedzera ASTM A252 kunoita kuti mapaipi esimbi eLSAW asvike pamhando, mashandiro, uye mwero wekuchengetedza unodiwa pakushandisa kwawo mukuisa mapombi.
