Habka wax-soo-saarka

saarayaasha tuubooyinka lsaw

Habka soo saarida Dhuumaha Dhererka Submerged-Arc Welded(LSAW) waa sida soo socota:

Baadhista saxanka Ultrasonic → shiidista cidhifyada → hore u laabashada → samaynta → alxanka ka hor → alxanka gudaha → alxanka dibadda → Kormeerka Ultrasonic → Kormeerka raajada → Kordhinta → tijaabada hydraulic →l.Chamfering → Kormeerka Ultrasonic → Baaritaanka raajada → Baaritaanka walxaha magnetic ee dhamaadka tuubada

Kala duwanaanshaha la ogol yahay ee Miisaanka iyo Cabirka

1. Dhexroor ka baxsan-Ku salaysan cabbirka wareegga ±0.5% ee dhexroorka dibadda ee la cayimay.

2. Wareega ka baxsan-Farqiga u dhexeeya dhexrooryada waaweyn iyo kuwa yar ee dibadda.

3. Toosinta-Isticmaalka 10 fuudh (3m) toosan oo la dhigay si ay labada daraf ula xiriiraan tuubada, 1/8 in. (3mm).

4. Dhumucda darbiga ugu yar meel kasta oo tuubada ka mid ah waa in aanay ka badnaan 0.01 in. (0.3mm) ee hoos yimaada dhumucda magaca ee la cayimay.

5. Dhererka cidhifyada aan la farsamayn waa inay ku jiraan -0+1/2 in. (-0+13mm) ee la cayimay.Dhererka cidhifyada mishiinada leh waa in ay noqdaan sida ay ku heshiiyaan soo saaraha iyo iibsadaha.

Tijaabada Makaanikada ee ASTM A671 LSAW Dhuumaha Birta Kaarboon:

Tijaabada xiisadda-isbeddelka guryaha xajinta ee wadajirka alxanka ah waa inay buuxiyaan shuruudaha ugu yar ee xoogga xajinta ugu dambeeya ee walxaha saxanka la cayimay.

Tijaabooyinka leexsan-hagaaya-alxanka-qaloocinta - Tijaabada qalooca waa in la aqbalo haddii aysan jirin dildilaacyo ama cillado kale oo ka badan 1/8 inch

Imtixaanka-garaaf Raadiyaha- Dhererka buuxa ee alxanka kasta ee fasalka X1 iyo X2 waa in si shucaac ah loo baaro si waafaqsan oo la kulmo sharuudaha ASME Boiler and Pressure Code Code, Qaybta toddobaad, cutubka UW-51.
