Suma kune zvinhu zvesimbi zveLSAW, giredhi uye mashandisirwo azvo

Mapaipi eSAW (Longitudinal Submerged Arc Welded) akasiyana nemamwe marudzi emapaipi akasungirirwa anoshandiswa mumapaipi. Anonyanya kushandiswa mumapaipi ekufambisa mafuta negasi,uye mashandisirwo ekuvaka akadai sekuvaka mabhiriji nematunnel.

Panyaya yemitemo, mapaipi eLSAW anoenderana nezvinodiwa neAmerican Petroleum Institute (API), International Organization for Standardization (ISO), pamwe neAmerican Petroleum Institute (NSAW).

Sangano reMainjiniya eMechanical (ASME). Mitemo iyi inotsanangura zvinodiwa pakukura, kuumbwa kwemakemikari, hunhu hwemakanika, uye zvinodiwa pakuyedza mapaipi eLSAW.

Mapaipi eLSAWanowanikwa mumhando dzakasiyana dzakadai seASTM A671, ASTM A672, ASTM A525,BS EN10210, BS EN10219, uye API 5L Gr. B. Kusarudzwa kwegiredhi kunoenderana nekushandiswazvinodiwa zvakaita sekumanikidzwa, tembiricha, uye rudzi rwemvura iri kutakurwa.

Mashandisirwo emapombi eLSAW akasiyana-siyana, uye anonyanya kushandiswa mumitsetse yekufambisa mafuta negasi, mapaipi emvura, uye mashandisirwo ekuvaka akadai sekuvaka mabhiriji nematunnel. Mapaipi aya anonyanya kufarirwa.pamusoro pemamwe mapaipi akasungirirwa sezvo achipa kurongeka kuri nani, simba rakakwirira, uye kugara kwenguva refu. Mapaipi eLSAW anogona kugadzirwa muhukuru hwakakura uye hurefu, zvichiita kuti ave akakodzera kushandiswa mumapaipi ekutumira zvinhu ari kure.

Mukupedzisa, mapaipi eLSAW anoita basa rakakosha mukufambisa mafuta negasi uye mashandisirwo aro. Anoenderana nezvinodiwa zvakasimba, anouya mumhando dzakasiyana, uye anogara kwenguva refu uye akavimbika.
