Daim ntawv thov ntawm ASTM A671 / A671MLSAW Cov Yeeb Nkab Hlau

Cov Txheej Txheem Tsim Khoom

Cov txheej txheem ntawm kev tsim cov yeeb nkab Longitudinal Submerged-arc Welded (LSAW) yog raws li nram no:

Ultrasonic phaj soj ntsuam → ntug milling → pre-bending → forming → Pre-welding → Internal welding → External welding → Ultrasonic tshuaj xyuas → X-ray tshuaj xyuas → Expanding → hydraulic kuaj → l. Chamfering → Ultrasonic tshuaj xyuas → X-ray tshuaj xyuas → magnetic particle tshuaj xyuas ntawm lub raj kawg

Kev Hloov Pauv Uas Tso Cai Hauv Qhov Hnyav thiab Qhov Ntev

1. Txoj Kab Uas Siv Sab Nraud - Raws li kev ntsuas ncig ntawm ± 0.5% ntawm txoj kab uas siv sab nraud uas tau teev tseg.

2. Qhov Tsis Sib Npaug - Qhov sib txawv ntawm cov kab uas hla sab nraud loj thiab me.

3. Kev Sib Tho - Siv ib txoj kab ncaj 10 ft (3m) uas muab tso rau kom ob sab kawg sib chwv nrog lub yeeb nkab, 1/8 nti (3 hli).

4. Thickness-Qhov tsawg kawg nkaus phab ntsa tuab ntawm txhua qhov chaw hauv cov yeeb nkab yuav tsum tsis pub ntau tshaj 0.01 nti (0.3 hli) nyob rau hauv qhov teev tseg nominal thickness.

5. Qhov ntev uas tsis tau tshuab yuav tsum nyob hauv -0,+1/2 nti (-0,+13 hli) ntawm qhov tau teev tseg. Qhov ntev uas tau tshuab yuav tsum yog raws li tau pom zoo ntawm tus neeg tsim khoom thiab tus neeg yuav khoom.

Kev Ntsuas Tshuab rau ASTM A671 LSAW Carbon Steel Pipe:

Kev Ntsuas Kev Nruj - Cov khoom sib txuas ntawm cov vuam sib koom ua ke yuav tsum ua tau raws li qhov yuav tsum tau ua tsawg kawg nkaus rau lub zog tensile kawg ntawm cov khoom siv phaj teev tseg.

Kev ntsuam xyuas qhov khoov uas siv txoj hlua khi hla — Kev ntsuam xyuas qhov khoov yuav tsum tau txais yog tias tsis muaj qhov tawg lossis lwm yam tsis zoo uas tshaj 1/8 nti (3 hli) hauv txhua qhov kev taw qhia nyob rau hauv cov hlau txuas lossis ntawm qhov txuas thiab cov hlau hauv paus tom qab khoov.

Kev Tshuaj Xyuas Duab Xoo Hluav Taws Xob - Tag nrho qhov ntev ntawm txhua qhov vuam ntawm chav kawm X1 thiab X2 yuav tsum tau tshuaj xyuas duab xoo hluav taws xob raws li thiab ua tau raws li qhov yuav tsum tau ua ntawm ASME Boiler thiab Pressure Vessel Code, Ntu xya, nqe UW-51.
