1. Kuongororwa kwekuonekwa kweelbow pombi fittings: kazhinji, kuongororwa kwemaziso asina kupfeka ndiyo nzira huru.Kuburikidza nekuongorora kwechitarisiko, inogona kuwana kukanganiswa kwekutaridzika kwekushongedza elbow pombi, uye dzimwe nguva shandisa 5-20 nguva yekukudza girazi kuongorora.Zvakadai sekurumwa kwemupendero, porosity, mamota ekuputira, kutsemuka kwepamusoro, kuiswa kwe slag uye kupinda, nezvimwewo. Chimiro chechimiro che weld chinogonawo kuyerwa ne detector welding kana sampuli.

2. Nondestructive inspection of elbow pipe fittings: kuongorora kwe slag, porosity, kuputika uye zvimwe zvikanganiso zvakavanzwa mu weld.X - ray inspection ndeye kushandisa X - ray kutora mapikicha e-welding seam, maererano nemafungiro asina kunaka kuti aone kana pane kukanganisa kwemukati, nhamba uye rudzi rwezvikanganiso.Iye zvino inonyanya kushandiswa ndiyo kusarudzwa kwe X-ray kuongorora, pamwe chete ne ultrasonic inspection uye magnetic inspection.Zvino maererano nechigadzirwa hunyanzvi zvinodiwa kuona kana weld inokodzera.Panguva ino, masaisai anoratidzwa anoonekwa pachiratidziri.Zvinoenderana nekuenzanisa uye kuzivikanwa kweaya anoratidzwa masaisai ane akajairika masaisai, ukuru uye nzvimbo yechirema inogona kutsanangurwa.Ultrasonic kuona kukanganisa kuri nyore kupfuura X-ray, saka inoshandiswa zvakanyanya.Nekudaro, ultrasonic inspection inogona kungotongwa nechiitiko chekushanda, uye haigone kusiya hwaro hwekuongorora.Iyo ultrasonic danda inotumirwa kubva kuprobe ichipinda musimbi, uye kana yasvika kune simbi-yemhepo interface, inoramba uye inopfuura nepakati weld.Kana pane zvikanganiso mu weld, iyo ultrasonic beam icharatidzwa kune probe uye inotakurwa, nokuti mukati mehurema hwe weld surface haisi yakadzika uye kuonekwa kwezvimedu zviduku, magnetic flaw yekuona inogona kushandiswawo.

3. Iyo mechanic zvimiro zvegokora pombi bvunzo: nondestructive kuyedza inogona kuwana hurema hwekuzvarwa kweiyo weld, asi haigone kujekesa michina yesimbi munzvimbo inopisa inokanganisa weld, saka dzimwe nguva kuita kushushikana, kukanganisa, kukotama uye. zvimwe zviedzo pane welded joint.Izvi zviedzo zvinoitwa nedare rekuedza.Iyo ndiro yekuyedza inoshandiswa yakanyatsobatanidzwa pamwe chete neiyo longitudinal seam yecylinder kuti ive nechokwadi chekuenderana mamiriro ekuvaka.Ipapo iyo mechanical properties ye test plate inoedzwa.Mukuita, majoini chete emagetsi esimbi matsva anoedzwa mune izvi.

4. Elbow pombi pressure test uye pressure test: nokuda kwechisimbiso chemudziyo chekuisa chisimbiso chinodiwa, mvura yekumanikidza bvunzo uye (kana) bvunzo yekumanikidza, kutarisa kuvharwa nekumanikidza kugona kwe weld.Nzira yacho ndeyekuisa jekiseni 1.25-1.5 nguva yekushanda kwemvura kana kuenzana nekushanda kwegasi (kunyanya nemhepo) mumudziyo, gara kwenguva yakati, uye woongorora kudonha kwemvura mumudziyo, uye kuongorora kana kune kubuda kunze, maererano neizvi zvinogona kuona kana weld inokodzera.
