Ko te tukanga o te hanga Longitudinal Submerged-arc Welded(LSAW) Pipe e whai ake nei:
Te tirotiro i te pereti ultrasonic → te mira tapa → te piko o mua → te hanga → Te mahi i mua i te whakapiri → te whakapiri o roto → te whakapiri o waho → te tirotiro i te Ultrasonic → te tirotiro hihi X → te whakawhānui → te whakamatautau waipēhi →l.Chamfering → Tirotiro ultrasonic → tirotiro X-ray → tirotiro matūriki autō i te pito ngongo

1. Te Diameter o waho-I runga i te inenga porowhita ±0.5% o te diameter o waho kua tohua.
2.-O-o-te-Roundness-Rerekētanga i waenga i nga diameter nui me te iti o waho.
3. Tirohanga-Whakamahia te 10 ft (3m) arai tika kia piri nga pito e rua ki te paipa, 1/8 inihi (3mm).
4. Matotoru-Ko te iti rawa o te matotoru o te pakitara i tetahi waahi o te paipa kaua e neke ake i te 0.01 inihi (0.3mm) i raro i te matotoru ingoa kua tohua.
5. Ko nga roa me nga pito kore miihini me uru ki roto -0+1/2 inihi (-0+13mm) o tera kua tohua.Ko nga roa me nga pito miihini ka rite ki te whakaaetanga i waenga i te kaihanga me te kaihoko.
Te Whakamatau Whakamatau—Ka tutuki nga ahuatanga whakaheke o te hononga paiherea ki nga whakaritenga iti mo te tino kaha o te pereti kua tohua.
Whakamatau-a-whakawhiti-a-a-a-whakamatautau-whakapiko —Ka whakaaehia te whakamatautau piko ki te kore he kapiti me etahi atu koha ka nui ake i te 1/8 inihi (3mm) ahakoa he aha kei roto i te whakarewa whakarewa, i waenga ranei i te whakarewa me te whakarewa i muri i te piko.
Whakamātautau Whakairoiro-whakairoiro-Ko te roa o ia wea o te karaehe X1 me X2 ka tirohia ma te reo irirangi kia rite ki nga whakaritenga o te ASME Boiler and Pressure Vessel Code, Wāhanga tuawhitu, kōwae UW-51.
