Inkqubo yokuVelisa

Inkqubo yokwenziwa koMbhobho weLongitudinal Submerged-arc Welded(LSAW) imi ngolu hlobo lulandelayo:

Ukukhangela ipleyiti yeUltrasonic → ukugoba komphetho → ukugoba kwangaphambili → ukwenza → ukuwelda kwangaphambili → i-welding yangaphakathi→ i-welding yangaphandle → Ukuhlolwa kwe-Ultrasonic → Ukuhlolwa kwe-X-ray → Ukwandisa → uvavanyo lwe-hydraulic →l.I-Chamfering → Uhlolo lwe-Ultrasonic → Uhlolo lwe-X-reyi → uhlolo lwamasuntswana omagnetic ekupheleni kwetyhubhu

Ukwahluka okuvumelekileyo kubunzima kunye nobukhulu

1. Idayamitha yangaphandle-Ngokusekwe kumlinganiselo wesangqa ±0.5% wedayamitha yangaphandle echaziweyo.

2. Ngaphandle kwe-Roundness-Umahluko phakathi kweedayamitha ezinkulu nezincinci zangaphandle.

3. Ulungelelwaniso-Ukusebenzisa i-10 ft (3m) i-straightedge ebekwe ukwenzela ukuba iziphelo zombini zidibene nombhobho, 1/8 ngaphakathi. (3mm).

4. Ukutyeba-Ubuncinane bodonga lobukhulu nakweyiphi na indawo kumbhobho abuyi kuba ngaphezu kwe-0.01 ngaphakathi (0.3mm) phantsi kobukhulu obuxeliweyo obuchaziweyo.

5. Ubude obuneziphelo ezingasetyenziswanga buya kuba ngaphakathi -0+1/2 phakathi. (-0+13mm) koko kuchaziweyo.Ubude obuneziphelo zoomatshini buya kuba njengoko kuvunyelwene ngazo phakathi komvelisi kunye nomthengi.

Iimvavanyo zoomatshini zeI-ASTM A671 LSAW Umbhobho weNtsimbi yeKhabhoni:

Uvavanyo lweTension-Iipropati ezinqamlezileyo zokuqina kwekhonkco elidityanisiweyo ziya kuhlangabezana nezona mfuno zisezantsi zokuqina kokuqina kwemathiriyeli yepleyiti echaziweyo.

Iimvavanyo eziguquguqukayo-ezikhokelwayo-Uvavanyo lwe-bend luya kwamkeleka ukuba akukho zintanda okanye ezinye iziphene ezidlula i-1/8 in.

Uvavanyo lweRadio-graphic-Ubude obupheleleyo beweld nganye yodidi lwe-X1 kunye ne-X2 buya kujongwa ngokwerediyo ngokuhambelana kwaye kuhlangabezene neemfuno zeKhowudi ye-ASME yeBhola kunye noxinzelelo lweVessel, iCandelo lesixhenxe, umhlathi UW-51.
