API Pipe vs 3PE Pipe

Mumapurojekiti makuru einjiniya akadai seoiri, gasi rechisikigo, uye mvura yemunisiparati, mapaipi anoshanda semusimboti wehurongwa hwekufambisa, uye kusarudzwa kwavo kunotarisisa kuchengetedzeka kweprojekiti, hupfumi, uye kusimba. API pombi uye 3PE pombi, maviri anoshandiswa zvakanyanya pombi zvigadzirwa, zvinowanzoiswa pamberi nezvikwata zveinjiniya. Nekudaro, ivo vanosiyana zvakanyanya mumagadzirirwo zviyero, maitiro ekuita, uye anoshanda mamiriro. Kunyatsonzwisisa maitiro avo kwakakosha pakuvandudza kunaka kweprojekiti.

Tsanangudzo uye Core Mashandiro Mamiriro

API pombi, ipfupi ye "American Petroleum Institute Standard Steel Pipe," inogadzirwa zvinoenderana nemitemo yenyika senge.API 5L simbi pombi. Iyo inovakwa kubva kune yakakwirira-yakasimba simbi uye inoumbwa kuburikidza isina musono rolling kana welding maitiro. Masimba ayo epakati ari musimba rayo repamusoro-kudzvanywa uye kusimba, zvichiita kuti rishandiswe zvakanyanya mukushandiswa kwepamusoro-soro senge marefu-refu emafuta uye gasi pombi uye shale gasi wellhead manifolds. Kugadzikana kwayo kwemaitiro mukupisa kwakanyanya kubva -40 ° C kusvika 120 ° C kunoita kuti ive chinhu chakakosha chekufambisa kwesimba.

3PE pombi inomirira "matatu-layer polyethylene anti-corrosion simbi pombi." Inoshandisa pombi yesimbi yakajairwa sehwaro, yakavharwa neatatu-layer anti-corrosion chimiro chine epoxy poda coating (FBE), adhesive, uye polyethylene. Yayo musimboti dhizaini inotarisana nekudzivirira ngura, ichiwedzera zvakanyanya hupenyu hwesevhisi yepombi nekutsaura ma microorganisms evhu uye electrolytes kubva pachigadziko chesimbi pombi. Munzvimbo dzinotyisa dzakaita semvura yemunisiparati, kugezwa kwetsvina, uye kutakura makemikari emvura, pombi ye3PE inogona kuwana hupenyu hwesevhisi anopfuura makore makumi mashanu, zvichiita kuti ive yakaratidza anti-corrosion mhinduro yekuvaka pombi yepasi.

Kuenzanisa Kwakakosha Kwekuita

Kubva pakuona kwepakati pekuita, mapaipi maviri anosiyana zvakajeka pakumisikidzwa kwawo. Panyaya yezvivakwa zvemuchina, API pombi kazhinji ine simba regoho riri pamusoro pe355 MPa, ine mamwe magiredhi epamusoro-simba (sengeAPI 5L X80) inosvika 555 MPa, inokwanisa kushingirira kushanda nesimba kudarika 10 MPa. 3PE pombi, kune rumwe rutivi, inonyanya kutsamira panheyo yesimbi pombi kuti iwane simba, uye anti-corrosion layer pachayo inoshaya simba-inotakura simba, zvichiita kuti ive yakakodzera kune yepakati- uye yakaderera-kudzvinyirira kutakura (kazhinji ≤4 MPa).

3PE mapaipi ane mukana wakakura mukupokana nekuora. Mamiriro avo matatu-matatu anogadzira mhinganidzo mbiri ye "kuzviparadzanisa kwemuviri + kuchengetedzwa kwemakemikari." Mayedzo ekupfapfaidza munyu anoratidza kuti corrosion rate yavo ingori 1/50 yepombi yesimbi isina chinhu. ApoAPI mapaipiinogona kudzivirirwa kubva pakuora kuburikidza nekugadzira uye kupenda, kushanda kwavo munzvimbo dzakavigwa kana pasi pemvura kuchiri kwakaderera kune iyo ye3PE mapaipi, inoda mamwe maitiro ekuchengetedza cathodic, ayo anowedzera mari yeprojekiti.

Sarudzo Strategies uye Indasitiri Maitiro

Sarudzo yeprojekiti inofanirwa kutevedzera musimboti we "scenarios fit": Kana iyo yekufambisa yepakati iri high-pressure oiri kana gasi, kana nharaunda yekushanda ikasangana nekuchinja kwakanyanya kwekushisa, mapaipi eAPI anofarirwa, aine mamakisi esimbi akadai seX65 neX80 achienderana neredhiyo yekumanikidza. Pamvura yakavigwa kana makemikari ekutakura mvura yetsvina, mapaipi e3PE isarudzo ine hupfumi, uye ukobvu hweiyo anti-corrosion layer inofanira kugadziridzwa zvinoenderana neiyo ivhu corrosivity level.

Ikozvino maindasitiri maitiro akanangana ne "performance fusion." Mamwe makambani ari kubatanidza iyo yakakwirira-yakasimba base material yeAPI pombi ine matatu-layer anti-corrosion chimiro che3PE pombi kugadzira "yakakwirira-yakasimba anti-corrosion composite pombi." Mapombi aya anosangana nezvinodiwa zvekutepfenyura kwepamusoro-soro uye kuchengetedzwa kwenguva refu kwekuora. Mapombi aya akatoshandiswa zvakanyanya mukugadzirwa kwemafuta egungwa uye gasi uye mapurojekiti ekuchinjisa mvura mumabheseni. Iyi nzira yekuvandudza inopa mhinduro iri nani yeinjiniya yepombi.
