Habka Wax Soo Saarka

Habka loo soo saaro Tuubooyinka Longitudinal Submerged-arc Welded (LSAW) waa sida soo socota:

Baaritaanka saxanka Ultrasonic → Shiididda geesaha → ka hor-laabashada → sameynta → Alxanka kahor → Alxanka gudaha → Alxanka dibadda → Kormeerka Ultrasonic → Kormeerka Raajada → Ballaarinta → Tijaabada Haydarooliga → l. Chamfering → Kormeerka Ultrasonic → Kormeerka Raajada → Kormeerka walxaha birlabta ee dhamaadka tuubada

Kala duwanaanshaha la oggol yahay ee Miisaanka iyo Cabbirka

1. Dhexroorka Dibadda - Ku salaysan cabbirka wareegga ±0.5% ee dhexroorka dibadda ee la cayimay.

2. Ka-baxsan-Meel-wareejin - Farqiga u dhexeeya dhexroorka dibadda ee waaweyn iyo kuwa yaryar.

3. Isku-dubarid - Adeegsiga 10 ft (3m) oo toosan oo la dhigay si labada darafba ay ula xiriiraan tuubada, 1/8 inji (3mm).

4. Dhumucda - Dhumucda derbiga ugu yar meel kasta oo tuubada ah waa inaysan ka badnaan 0.01 inji (0.3mm) marka loo eego dhumucda magacaaban ee la cayimay.

5. Dhererka leh darafyo aan la madhin waa inuu ahaadaa -0+1/2 inji (-0+13mm) ee la cayimay. Dhererka leh darafyo madhin waa inuu ahaadaa sida ay isku raaceen soo saaraha iyo iibsadaha.

Tijaabooyinka Farsamada ee Tuubooyinka Birta Kaarboon ee ASTM A671 LSAW:

Tijaabada Xiisadda - Sifooyinka jiidista ee kala-goysyada alxanka waa inay buuxiyaan shuruudaha ugu yar ee xoogga jiidista ugu dambeeya ee walaxda saxanka ee la cayimay.

Tijaabooyinka leexashada ee hagaya-alxanka-leexashada — Tijaabada leexashada waa in la aqbalaa haddii aysan jirin dildilaacyo ama cillado kale oo ka badan 1/8 inji (3mm) jiho kasta oo ku yaal birta alxanka ama inta u dhaxaysa alxanka iyo birta salka ka dib leexashada.

Baaritaanka Raadyowga - Dhererka buuxa ee alxan kasta oo fasalka X1 iyo X2 ah waa in si raajada ah loo baaraa iyadoo la raacayo oo la buuxinayo shuruudaha Xeerka Biyo-mareenka iyo Maraakiibta Cadaadiska ee ASME, Qaybta toddobaad, cutubka UW-51.
