LSAW vs HSAW (SSAW) Imiyoboro: Itandukaniro ryingenzi

Nigute umuyoboro wa SSAW ukemura ibibazo?

Ubushobozi bwumuvuduko niigishushanyo - gishingiye- biterwa naOD, uburebure bwurukuta, urwego rwicyuma (SMYS / impagarara zemewe), ibintu byashushanyije, amafaranga yo kwangirika, nubushyuhe bwo gukoramunsi ya kode ikoreshwa. Kuri umuyoboro wa SSAW / HSAW, ubunyangamugayo bwumutekano mukugenzura iIkirangantego: abaguzi basobanura nezabyuzuye - uburebure bwa weld seam NDT (UT / RT kumushinga ITP)kandi bisaba kwipimisha hydrostatike mugihe bibaye ngombwa, kubyemera rero bishingiye kubudakemwa bwanditse hamwe nibimenyetso byikizamini. Itegeko rifatika mugutanga amasoko ni: niba serivisi irenze - ibyago (umuvuduko mwinshi, serivisi isharira, cyangwa ibisabwa nyirubwite), komeza itegeko kuriicyiciro / WT guhitamo no kugereranya NDT urugeroaho kwishingikiriza kubisanzwe "imikorere yigitutu".

Ku mishinga ya SSAW / HSAW, "pass / gutsindwa" ni gake cyane kubijyanye nimbaraga rusange zisabwa - iramanuka kuriindero yo kwemerera. Abaguzi mubisanzwe bafunga ibintu bitatu byingenzi, kandi aha niho rwose Umuyoboro wa Octal ushyira kugenzura nibimenyetso.

• Ihame ridahwitse (gushiraho → gusudira gushikamye):Ubwiza bwa tekinike ihagaze mbere yo gusudira. Niba imiterere ya spiral idahamye, urabibona nyuma nkukokuzerera mu kantu, ovality drift, hamwe numwirondoro wamasaro utaringaniye, hanyuma bigatera NDT yinyongera no gusana ibiganiro. Umuyoboro wa Octal ugenzura gushiraho - hejuru kandi ugakomeza ibipimo byo gusudira imbere mu idirishya ryasobanuwe bityo ikidodo kiguma gihamye kuva kumuyoboro wambere kugeza kucyanyuma muri byinshi.
• Ingano ya NDT ni ubugenzuzi - gihamya (ntabwo "twakoze ibizamini"):Icyo abaguzi babaza mubyukuri ni:Ikirangantego cya tekinike kirasuzumwa uburebure bwuzuye? Ni ubuhe buryo, kandi ni ubuhe buryo bwo kwemerwa?Umuyoboro wa Octal uhuzaUT / RTn'itegeko ryimyitwarire (wemere / re - ikizamini / kwanga) kugipimo ngenderwaho nu mushinga ITP, kandi gitange ibimenyetso byubugenzuzi nkigice cyo kurekura - ibi nibyo bibuza urubuga gufata amanota no gusubiramo -.
• Gukurikirana inyandiko zirokoka ukuri kurubuga:Kwangwa kwinshi bibaho nyuma yo gutanga iyo imiyoboro yamaze gutegurwa kandi umukiriya ntashobora kwiyungaubushyuhe / coil → ikimenyetso cyerekana imiyoboro → NDT / hydro raporo → MTC. Umuyoboro wa Octal utanga paki ikurikirana (EN 10204 3.1; 3.2 kubisabwa) hamwe na mape ya mapping, bityo QA irashobora gusohora ibikoresho idakurikiranye amahuza yabuze.

Iyo abaguzi babajijeitandukaniro hagati ya LSAW na HSAW, ikibazo nyacyo ntabwo "isahani vs coil" - ni bwo bwoko bw'ikidodo bugabanya ibyemezo, ibyago byo mumirima, hamwe na gahunda yerekanwe munsi yumushinga.
