Paerewa: ASME DIN JIS BS GB/T JB SH HG, penei: GB/T12459-2017, GB/T13401-2017, ASME B16.9, SH3408, SH3409,HG/T21635,DL/T695,SY/DINT0510
Whakamahinga: wai, inu, pia, kai, petrochemical, mana karihi, miihini, taputapu rongoa, maniua, hanga kaipuke, parewai, paipa, aha atu.
Te takai: pouaka rakau, kaata A ape i te hono ki te r o te potae rihi, ka iti te kikokore me te ahotea nui.A, no te splicing, Ko nga whakaritenga ahunga tui fehokotaki'anga e whakaaetia anake ki te kia radial me circumferential.Ka taea e nga potae nui te tango i tenei whakaritenga a muri ake nei.Me hiahia te tawhiti o te mokowhiti, he nui ake i te 3δ me te kore e iti iho i te 100mm (ko te waahi e pa ana ki te wera he waahi tino taumaha, a ka wera te hanganga matū o tenei rohe. Na reira, me karo i te rohe taumaha-nui, e pa ana ki te matotoru .E ai ki nga wheako mahi, ko te roa o te ahotea he nui ake i te 3δ me te kore e iti iho i te 100mm).Heoi, he uaua mo nga taputapu whakamatao ki te whakatutuki i tenei whakaritenga me te mea motuhake.
Hemispherical Pipe potae
Whai muri i te taapiri, ko te mahunga kua honoa me te whakahiato kia 100% te hihi, te whakamatautau ultrasonic ranei, a ka whai te taumata tohu i te anga taputapu.Ko te taumata tirotiro me te ōwehenga o te tui weld i hangaia he rite ki te anga taputapu, he tino moumou.Tauira: Mena he 20% te whakamatautauranga o te anga taputapu, he tohu III.Ko te weld weld bulkhead me te weld whakamutunga he tohu III ano, a ko te whakarea hononga he 0.85;
Mena he 100% te whakamatautau o te whare taputapu, he tohu a II.He tohu II ano te weld mokowhiti me te weld whakamutunga, a ko te whakarea hononga he 1
No reira, ahakoa he 100% te whakamatautauranga o te whakahiatotanga nui, he rereke te taumata tohu, ka whai i te anga taputapu.
Engari kia tupato ki te tukanga hangahanga:
Ko te huarahi tika ko: te parai (tuhi) - ka whakahiatohia nga papa iti ki nga papa nui - te hanga - te whakamatautau kore-whakangaro.
Mena he he te whakamatautau i mua i te hanga, kaore e taea te whakamana i te kounga o te hua i muri i te hanga.Arā, ko te whakamātautau kore-whakangaromanga e pā ana ki te whakamātautau mutunga kore-whakangaro.
