Gasi Pipeline Hazardous Factors

Mumamiriro ezvinhu akajairwa, gasi rinotakurwa nenzira yakavharwa, kana iyo system ikatadza kutungamira mukutakurwa kwegasi rechisikigo rinodonha, gasi rechisikigo rinosanganiswa nemhepo kugadzira gasi rinoputika kuti risvike painoputika kana nyaya yemvura inopfuta. kuputika.

1. Piping zvinhu kuremara kana welding kuremara.Kukanganisa kwepombi kunogona kutungamirira kune simba repombi kunyanya kutsemuka kana kuputsika, kuvakwa kwehutano, asi kure, hurombo husina kunaka hwemajoini akaiswa mutopota kana kupera kwekupinda, zvichiita kuti simba repombi rive risina kukwana, haugoni kuchengetedza zvakachengeteka kushanda zvinodiwa.Izvo zvakaitika mukudonha kwegasi, zvichiunza tsaona yemoto.

2. Kupfeka kwepombi kwemukati nekuora.Gasi rine guruva zvidimbu sejecha, ngura, kusvibiswa kwemagetsi nemhepo inoyerera, unogona kupfeka kukuvadzwa kwepombi, chirongwa chegasi rechisikigo rine C02, CO: gasi rine acidic rakanyungudutswa mumvura kuti riite H: CO pasimbi Kune zvimwe zvinoparadza.Kana dova remvura rakundikana kana kuti pressure test pigging isina kunyatsoomesa chubhu mvura yekurangarira inogadzirwa mukati mecorrosion, corrosion inokonzera kukuvara kwepombi, yakonzera tsaona.

3. Nzvimbo yekunze yekuora kwepombi.Nokuti pombi ekunze rukoko muchokufambisa, kuvaka kukuvara.Pasina kugadziriswa nenguva kana kusakwanisa kuzadzisa zvinodiwa zvinorwisa-corrosion, pombi cathodic dziviriro system kutadza, pombi inoisa ivhu rakasimba rinoparadza rakatenderedza chirimwa midzi anti-corrosion inotungamira kune tsaona.Pedyo nepombi yegesi iri pasi pematambo emagetsi akafanana, njanji yemagetsi,pombi yemafutauye gasi mapaipi parallel kana variable kugovera zvivako, nyore gasi pombi yakavigwa pedyo anorasika ikozvino kuwedzera pombi ngura ngozi, zvichikonzera leakage, moto, kuputika uye dzimwe tsaona.

4. Stress kuputika.Kuvapo kwekunetseka kwakasara mukugadzira pombi, kune mutsauko wetembiricha pakati pekushisa uye tembiricha yekushandisa yekuvakwa kwepombi, zvichiita kuti pombi iri pamwe nekushushikana kwekupisa kunogadzirwa munzira yeaxial, inogona kukonzera kuputika kwepombi.

5. Pipeline yakaiswa mukushanda.Kana pombi yaiswa mukushanda, nguruve isina kunyatsoomesa, mvura yakachena yakasara mupombi, inomhanyisa kuparara kwepombi, zvisaririra zvepombi zvinomhanyisa mavharuvhu, kupfeka kwemidziyo uye zvigadzirwa zvekuora, kuwedzera kuvuza kune njodzi.

Nzira dzekudzivirira uye dzekudzivirira moto
Matanho makuru ndeaya: (I) kutonga uye kubvisa mabviro ekupisa;(2) kunyatsodzora kunaka kwemidziyo, kusarudzwa kwevanokwanisa kunetseka zvakanyanya, kuparadzanisa, kuyerera, kudzvanywa, tembiricha chiridzwa;(3) pamberi pekutumirwa kwepipeline pressure test inodiwa;(4) inogara ichiongorora uye kugadzirisa midziyo, chiridzwa;(5) muchiteshi kuvaka nzvimbo inorambidza moto, zviratidzo zvengozi zvakanamirwa panzvimbo yebasa;(6) kuvandudzwa kwemitemo nemirau uye kuchengetedzwa kwemaitiro, yakasimba chirango nzira yekudzivirira tsaona Kuvhiya kwakatungamira kune gasi rechisikigo kuvuza;(7) teerera kune nzendo dzekuongorora, kuona matambudziko uye kurapwa panguva yakakodzera: (8) nguruve Bvisa jekiseni remvura kurapwa pamberi pemarara yakaoma kuti icheneswe nguva dzose, kutarisa zviri mukati mesimbi.
