Inkqubo yoMveliso

Inkqubo yokwenza iLongitudinal Submerged-arc Welded (LSAW) Pipe yile ilandelayo:

Ukukhangela ipleyiti ye-ultrasonic → ukugaywa komphetho → ukugoba kwangaphambili → ukwakheka → Ukuwelda kwangaphambili → Ukuwelda kwangaphakathi → Ukuwelda kwangaphandle → Ukuhlolwa kwe-ultrasonic → Ukuhlolwa kwe-X-ray → Ukwandisa → uvavanyo lwe-hydraulic → l. Ukuxubha → Ukuhlolwa kwe-ultrasonic → Ukuhlolwa kwe-X-ray → Ukuhlolwa kwe-magnetic particle ekupheleni kwetyhubhu

Utshintsho oluvumelekileyo kuBunzima kunye noBungakanani

1. Ububanzi bangaphandle-Ngokusekelwe kumlinganiselo ojikelezayo ±0.5% yobubanzi bangaphandle obuchaziweyo.

2. Umahluko ongaphandle kobubanzi phakathi kobubanzi obukhulu nobubanzi obuncinci bangaphandle.

3. Ulungelelwaniso-Ukusebenzisa umphetho othe tye ongama-3m ubude ukuze omabini amacala adibane nombhobho, 1/8 in. (3mm).

4. Ubukhulu-Ubude bodonga obuncinci nakweyiphi na indawo kumbhobho akufuneki bube ngaphezulu kwe-0.01 intshi (0.3mm) phantsi kobukhulu obumiselweyo.

5. Ubude obuneziphelo ezingafakwanga matshini buya kuba ngaphakathi kwe -0,+1/2 intshi (-0,+13mm) kwezo zichaziweyo. Ubude obuneziphelo ezifakwe ngomatshini buya kuba njengoko kuvunyelwene phakathi komenzi kunye nomthengi.

Uvavanyo lweMechanical lwe-ASTM A671 LSAW Carbon Steel Pipe:

Uvavanyo loxinzelelo—Iimpawu zoxinzelelo ezinqamlezileyo zejoyinti edibeneyo ziya kuhlangabezana neemfuno ezisezantsi zokuqina koxinzelelo lwento ekhankanyiweyo yepleyiti.

Uvavanyo olugobileyo olukhokelwa yi-transverse-guided weld-belt —Uvavanyo lokugoba luya kwamkeleka ukuba akukho mifantu okanye ezinye iziphene ezidlula i-1/8 intshi (3mm) kulo naliphi na icala ezikhoyo kwisinyithi esigobileyo okanye phakathi kwesinyithi esigobileyo kunye nesinyithi esisisiseko emva kokugoba.

Uvavanyo lweRadiographic-Ubude obupheleleyo be-weld nganye yeklasi X1 kunye ne-X2 buya kuhlolwa ngeradiographic ngokuhambelana neemfuno ze-ASME Boiler kunye nePressure Vessel Code, iCandelo lesixhenxe, isiqendu UW-51.
