Spiral chitoliro fakitale zichitike pamaso mayeso makina ntchito ndi flattening mayeso ndi flaring mayeso, ndi kukwaniritsa zofunika muyezo. Njira yoyendera chitoliro cha chitsulo cha Spiral ndi motere:
1, Kuchokera pamaso pake, ndiko kuyang'ana kowoneka. Kuyang'anira zolumikizira zowotcherera ndi njira yosavuta koma njira yoyesera yogwiritsidwa ntchito kwambiri ndi gawo lofunikira pakuyesa kwazinthu, zolakwika zazikulu ndi zopatuka zimapezeka pamwamba pa kukula kwa weld. Nthawi zambiri ndi maso, ndi muyezo chitsanzo, n'zopimira ndi mayeso zida monga galasi kukulitsa. Ngati chowotcherera pamwamba chilema, weld zolakwika pakhoza kukhala mkati.

2, Njira zoyesera thupi: Njira yoyesera thupi ndikugwiritsa ntchito kuyesa kwa zochitika zakuthupi kapena njira yoyesera. Kapena mkati mwa kuwunika zolakwika zakuthupi, ndipo nthawi zambiri amagwiritsidwa ntchito njira za NDT. Kuzindikira zolakwika za NDT, kuzindikira kwa ma radiation, kuyesa kulowa, kuyesa maginito ndi zina zotero.

3, Kuyesa kwamphamvu kwa ziwiya zopanikizika: zotengera zopanikizika, kuwonjezera pakuyesa kolimba, komanso kuyesa mphamvu. Pali mayeso odziwika a mayeso awiri a hydraulic ndi kuthamanga kwa mpweya. Iwo akhoza kuyesedwa pogwira ntchito pansi pa ziwiya zopanikizika ndi ma welds compactness. Kuyesa kwa hydrostatic pressure ndikovuta kwambiri kuposa kuthamanga kwa mayeso ndipo, nthawi yomweyo zinthu zoyesa zitangowononga madzi, zovuta za ngalande za chinthucho ndizofunikira kwambiri. Koma chiopsezo ndi chachikulu kuposa kuyesa kukakamiza mayeso. Akayesedwa, ayenera kutsatira njira zoyenera zotetezera kuti apewe ngozi panthawi ya mayeso.

4, Mayeso ang'onoang'ono: kuwotcherera kwamadzi kapena gasi, komwe sikuli zofooka zowotcherera, monga ming'alu yolowera, pores, slag, kulowa kosakwanira minofu yotayirira ndi zina zotere, zitha kugwiritsidwa ntchito kupeza mayeso a kachulukidwe. Njira zoyezera compactness ndi: kuyesa palafini, kuyesa madzi, madzi amayesa.

5, The mayeso hydrostatic ayenera kuchitidwa aliyense chitoliro hydrostatic mayeso popanda kutayikira, kuthamanga mayeso atolankhani Mawerengereni P = 2ST / D kumene S- hydrostatic mayeso maganizo mayeso Mpa, hydrostatic mayeso maganizo mayeso malinga lolingana zitsulo muyezo limatchula osachepera digiri ya zokolola ( Q235 ndi 235Mpa) 60% ya zosankhidwa. Nthawi yowongolera: D <508 kuyesa kukakamiza kugwira nthawi yochepera masekondi a 5; D≥508 kuyesa kuthamanga kumagwira nthawi yochepera 10 masekondi 4, kuyesa kosawononga kwa chitsulo chowotcherera msoko, mizere yowotcherera ndi ma circumferential olowa ayenera X-ray kapena kuyendera kwa akupanga. Pakuti wamba kuyaka madzimadzi zoyendera ozungulira zitsulo kuti kuwotcherera 100% SX-ray kapena ultrasound mayeso, ntchito madzi, zimbudzi, mpweya, Kutentha nthunzi ndi zina zambiri kufala madzimadzi ndi kozungulira weld zitsulo chitoliro ayenera X-ray kapena akupanga kuyendera macheke ( 20%).

Zotsatira za mayeso a chitoliro cha chitsulo chozungulira, chitoliro chozungulira nthawi zambiri chimagawika m'magulu atatu: Oyenerera, okonzanso komanso zotsalira. Woyenerera amatanthauza khalidwe ndi maonekedwe a khalidwe kwenikweni kukwaniritsa mfundo kapena luso yobereka ndi kuvomereza mikhalidwe muzimu zitsulo chitoliro; rework amatanthauza khalidwe ndi maonekedwe a mkati khalidwe si mokwanira kutsatira mfundo kuvomereza ndi Mvula thupi, koma kulola kukonza pambuyo kukonza akhoza kukumana mfundo ndi kuvomereza zinthu mozungulira chitoliro; zinyalala amatanthauza substandard khalidwe ndi maonekedwe a mkati khalidwe la ozungulira zitsulo akadali osafika muyezo ndi kuvomereza mikhalidwe salola kukonzanso kapena kukonzanso pambuyo pake.
