Lub kauv seam submerged arc welded steel yeeb nkab muaj cov phab ntsa tuab, zoo li zoo, sib npaug sib npaug, thiab ruaj khov. Lub kauv seam submerged arc welded steel yeeb nkab muaj qhov tsis sib xws ntawm phab ntsa tuab thiab tsis sib xws ntawm cov yeeb nkab steel. Qhov nyias nyias ntawm cov yeeb nkab steel yuav yooj yim tawg. Qhov tsis sib xws ntawm phab ntsa ntawm cov yeeb nkab steel yog Ib qho tshwm sim uas yooj yim tshwm sim thaum lub sij hawm dov hloov txheej txheem ntawm cov kav hlau. Cov phab ntsa tsis sib luag ntawm cov kav hlau steel feem ntau yog tshwm sim hauv cov phab ntsa tsis sib luag, cov phab ntsa tsis sib luag, thiab cov phab ntsa tuab lossis nyias nyias ntawm lub taub hau thiab tus Tsov tus tw. Cov ntsiab lus yog:

1: Cov phab ntsa tsis sib xws ntawm lub taub hau thiab tus Tsov tus tw
Ua rau: 1) Lub hauv ntej kawg ntawm lub kauv seam submerged arc welded steel yeeb nkab dawb paug yog txiav nrog ib tug inclination thiab loj heev khoov, thiab lub centering qhov ntawm cov yeeb nkab dawb paug tsis yog, uas yuav yooj yim tsim ib tug tapered steel yeeb nkab taub hau nrog. tsis sib xws phab ntsa thickness; 2) Lub elongation coefficient loj heev thaum perforating, thiab cov menyuam Cov kev sib hloov ceev yog siab dhau thiab dov tsis ruaj khov; 3) Cov hlau tsis ruaj khov pov tseg los ntawm lub tshuab xuas nrig ntaus tuaj yeem ua rau cov phab ntsa tsis sib xws ntawm qhov kawg ntawm lub raj capillary.

2: Tsis sib npaug kauv phab ntsa thickness
Cov laj thawj yog: 1) Cov phab ntsa tuab tsis sib xws los ntawm kev hloov kho xws li qhov tsis raug dov qhov nruab nrab ntawm lub tshuab tho, lub kaum sab xis inclination tsis sib xws ntawm ob lub chais, los yog me me rau pem hauv ntej nias tus nqi, feem ntau muab faib rau hauv ib lub kauv raws tag nrho ntev ntawm lub tapered. steel yeeb nkab; 2) Cov phab ntsa tsis sib xws tshwm sim los ntawm kev qhib ntxov ntxov ntawm cov menyuam yaus hauv nruab nrab, kev hloov kho tsis raug ntawm cov menyuam hauv nruab nrab, thiab kev co ntawm lub ejector thaum lub sij hawm dov feem ntau yog muab faib rau hauv cov kauv raws tag nrho ntev ntawm cov yeeb nkab steel tapered.
