Tukanga Hangahanga oASTM A252 LSAW Paipa maitai:

Longitudinal Submerged-arc Welded(LSAW) Pipe tango i te hangarau arc fehokotaki'anga submerged arc fehokotaki'anga, te whakamahi i whakakī fehokotaki'anga, parenga matūriki rere tanumia pewa.

Ko te LSAW te whakarāpopototanga reo Ingarihi o te pewa submerged paiherea paipa maitai tui tika.Ko te tukanga whakaputa o te pewa kua rukuhia he paipa tira whiri tika kei roto ko te hangarau hanga JCOE, te hangarau whakahiato pewa ruku me te hangarau hanga UOE.

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

Hanga matū:

Ko te maitai kia kaua e neke ake i te 0.050 % phosphorous.

Nga Whakamatau Miihini me te NDT moASTM A252 LSAW Paipa maitai:

Whakamātautau NDT(RT).

Whakamatau Hydrostatic

Whakamātautau Miihini

Whakamatau Piko—he pai te roa o te putorino me tu tonu ka piko i te matao ki te 90° huri noa i te mandrel porotakaroa.

Whakamātautau whakarata-ahakoa kaore e hiahiatia he whakamatautau, ka taea e te paipa te whakatutuki i nga whakaritenga whakamatautau papatahi.

Te whakamatautau wai-pateko—engari ka whakaaetia, ka tukuna ia roa o te putorino ki te whakamatautau wai-pateko me te kore e pakaru i te pakitara paipa.

Te whakamatautau hiko kore-hei rereke ki te whakamatautau wai-pateko, ka whakamatauria te tinana katoa o ia paipa ki te whakamatautau hiko kore kino.ki te mahia he whakamatautau hiko kore kino, me tohu nga roa ki nga reta "NDE"

Ko te whakamatautau ultrasonic

Ko te whakamātautau eddy nāianei

Te tono oASTM A252 LSAW Paipa maitai:

Ko te paipa i whakahauhia i raro i tenei whakaritenga mo nga puranga paipa e mahi ana te pukoro rino hei mema kawe kawenga pumau, hei anga ranei hei hanga i nga puranga raima whakarewa.

Te manawanui o te diameter o waho, te matotoru o te pakitara, te roa me te taumaha:

Ko te Diamita o waho	Ko te diameter o waho o nga puranga paipa kaua e rereke atu i te ±1% mai i te diameter o waho kua tohua.
Te matotoru o te pakitara	Ko te matotoru o te pakitara i tetahi waahi kaua e neke ake i te 12.5% i raro i te matotoru pakitara kua tohua.
Te roa	Ko nga putu paipa me hoatu ki nga roa matapōkere kotahi, ki nga roa matapōkere rua, ki nga roa riterite ranei kua tohua i roto i te ota hoko, i runga i nga rohe e whai ake nei:	Nga roa matapōkere kotahi	16 ki te 25ft (4.88 ki te 7.62mm), inihi
		Nga roa matapōkere rua	Neke atu i te 25ft (7.62m) me te iti rawa o te 35ft (10.67m)
		Te roa o te rite	te roa i tohua me te rerekee whakaaetia o ±1 inihi.
Taumaha	Ko ia roa o te puranga paipa me pauna motuhake, a kaua e rereke te taumaha i te 15% neke atu ranei i te 5% i raro i tona taumaha ariā, ka tatauhia ma te whakamahi i tona roa me tona taumaha mo ia waeine roa.
