Tsanangudzo Yakadzama YeInspection process ye Lined Pipes

Nekuvandudzwa kwezvivakwa zvemaindasitiri uye nekuvandudzwa kwezvinodiwa zvekuchengetedza kwezvakatipoteredza, mapaipi akamisikidzwa anoshandiswa zvakanyanya mumakemikari, simba, mvura uye mamwe minda nekuda kwezvakanaka zvadzo senge corrosion resistance uye kuwedzera hupenyu hwesevhisi. Zvisinei, hutano hwemapombi ane mitsetse hunokanganisa zvakananga kushanda kwavo uye kuchengeteka, saka kuongorora kwesayenzi kunokosha. Ichi chinyorwa chichasuma maitiro ekuongorora emapombi ane mitsetse zvakadzama kubatsira makambani ane hukama kudzora kunaka kwechigadzirwa.

1. Kuongororwa kwekuonekwa

Kuongororwa kwechitarisiko ndiyo danho rekutanga pakuongorora mapaipi ane mitsetse, kunyanya kutarisa kana pane kukanganisa kwakadai sekutsemuka, bubbles, scratches, nezvimwewo pamusoro pepombi. Mainspector anowanzo shandisa magirazi ekuona kana kuti magirazi ekukudza simba akaderera{{2}kukubatsira kuona kuti mukati nekunze kwepombi kwakatsetseka uye pasina kukuvara kuri pachena. Kunyangwe chinongedzo ichi chiri nyore, chinogona kusabvisa zviri pachena zvigadzirwa zvisina kukodzera uye kuisa hwaro hwekuongorora kunotevera.

2. Dimension kuyerwa

Dimension kuyerwa inhanho yakakosha kuve nechokwadi chekuti pombi yakamisikidzwa inosangana nezvinodiwa zvekugadzira. Izvo zvinyorwa zvekuongorora zvinosanganisira parameters senge dhayamita yemukati, dhayamita yekunze, ukobvu hwemadziro uye kureba kwepombi. Kazhinji, maturusi akadai severnier calipers uye ultrasonic ukobvu geji anoshandiswa kuyera chaiyo kuona kuti saizi yepombi iri mukati meiyo inobvumirwa kushivirira renji. Kana saizi yekutsauka yakakurisa, inogona kukonzera kunetsa kwekuisa kana kukanganisa mashandiro, saka chinongedzo ichi chinofanira kunyatsodzorwa.

3. Nondestructive test

Nondestructive kuyedza ndiyo yakakosha yekubatanidza kwemhando yekuongorora kwepombi dzakamisikidzwa, kunyanya kusanganisira ultrasonic bvunzo, radiographic kuyedzwa uye magineti particle kuyedzwa. Ultrasonic test inoshandiswa kutsvaga kuputika kana pores mukati mepombi; radiographic test inogona kuratidza zvakajeka kugoverwa kwekuremara mukati mepombi; Magnetic particle testing akakodzera kuona nzvimbo kana pedyo-pakatsemuka. Nzira idzi dzinogona kunyatsoongorora kunaka kwayo kwemukati pasina kuparadza pombi kuti ive nechokwadi chekuvimbika uye kuchengeteka kwepombi.

4. Muedzo wepressure

Pressure test inoshandiswa kuona kudzvanywa kwepombi yakamisikidzwa. Kazhinji, kudzvanywa kwemvura kana kuyedza kwemhepo kunoshandiswa kudzvanya mukati mepombi kusvika 1.5 nguva yedhizaini yekumanikidza uye kuichengeta kune imwe nguva yenguva yekuona kana paine kuvuza kana deformation. Ichi chinongedzo chinogona kunyatso kusabvisa mapaipi ane substandard pressure resistance uye ive nechokwadi chekuchengetedzwa kwawo mukushandiswa chaiko.

5. Muedzo wekuita kwemakemikari

Kune mapaipi akamisikidzwa ezvinangwa zvakakosha, bvunzo dzekuita kemikari inodiwa zvakare, senge corrosion resistance bvunzo uye yakanyanya tembiricha kuramba bvunzo. Nekutevedzera mamiriro ekushandiswa chaiwo, kugadzikana-kwenguva refu kwepombi kunoongororwa kuona kuti inoenderana nezvinodiwa nemaindasitiri chaiwo.

Nzira yekuongorora yemapombi akaiswa mutsetse inovhara huwandu hwakazara hwekuongorora kubva pakuonekwa kusvika pakuita. Chete nekunyatso kutevedzera zviyero zvekuongorora ndipo panogona kuve nechokwadi chemhando yechigadzirwa uye kuchengetedzwa kwakavimbika kunogona kupihwa kune maindasitiri ekushandisa.
