Pipe yeAPI vs Pipe ye3PE

Mumapurojekiti makuru einjiniya akadai semafuta, gasi rechisikigo, uye mvura yemumaguta, mapaipi anoshanda senzvimbo huru yekufambisa, uye kusarudzwa kwawo kunosarudza zvakananga kuchengetedzeka kweprojekiti, kuchengetedza mari, uye kugara kwenguva refu. Pipe yeAPI nepaipi ye3PE, zvigadzirwa zviviri zvepaipi zvinoshandiswa zvakanyanya, zvinowanzo kupihwa pekutanga nemapoka einjiniya. Zvisinei, zvakasiyana zvakanyanya mumatanho ekugadzira, maitiro ekushanda, uye mamiriro anoshanda. Kunzwisisa kwakakwana hunhu hwavo kwakakosha pakuvandudza hunhu hweprojekiti.

Tsanangudzo uye Maitiro Ekushandisa Kwakakosha

Pipe yeAPI, muchidimbu zvinoreva "American Petroleum Institute Standard Steel Pipe," inogadzirwa zvichienderana nezvinodiwa pasi rose zvakaita seAPI 5L simbi pombiYakavakwa nesimbi yakasimba uye inogadzirwa kuburikidza nemaitiro ekumonera kana kusanganisa. Simba rayo guru riri mukusimba kwayo kwekumanikidza uye kusimba kwekudhonza, zvichiita kuti ishandiswe zvakanyanya mukushandiswa kwekumanikidza kwakanyanya senge mapaipi emafuta negesi anofamba kure uye manifolds egasi reshale. Kugadzikana kwayo muchimiro chekupisa kwakanyanya kubva -40°C kusvika 120°C kunoita kuti ive chinhu chakakosha chekufambisa simba.

Pipe ye3PE inomiririra "pombi yesimbi yepolyethylene ine mativi matatu inodzivirira ngura." Inoshandisa pombi yesimbi yakajairika sehwaro, yakafukidzwa nechimiro chekudzivirira ngura chine mativi matatu chinosanganisira epoxy powder coating (FBE), glue, uye polyethylene. Dhizaini yayo huru inotarisa pakudzivirira ngura, zvichiwedzera zvakanyanya hupenyu hwepombi nekuparadzanisa tupukanana twevhu nema electrolytes kubva pahwaro hwepombi yesimbi. Munzvimbo dzine ngura zvakanyanya dzakadai semvura yemumaguta, kurapwa kwetsvina, uye kutakurwa kwemakemikari, pombi ye3PE inogona kuwana hupenyu hwebasa hwemakore anopfuura makumi mashanu, zvichiita kuti ive mhinduro yakasimbiswa yekudzivirira ngura pakuvaka pombi dzepasi pevhu.

Kuenzanisa Kwekushanda Kwakakosha

Kubva pamaonero ekushanda kwepakati, mapaipi maviri aya akasiyana zvakajeka pakuisa kwawo. Panyaya yehunhu hwemakanika, mapaipi eAPI anowanzova nesimba rekugadzira rinodarika 355 MPa, ane mamwe magiredhi esimba rakakwirira (akadai seAPI 5L X80) inosvika 555 MPa, inokwanisa kutsungirira kumanikidzwa kwekushanda kunodarika 10 MPa. 3PE pombi, kune rumwe rutivi, inonyanya kushandisa pombi yesimbi yesimbi kuti isimbise, uye layer yekudzivirira ngura pachayo haina simba rekutakura kumanikidzwa, zvichiita kuti ive yakakodzera kutakurwa kwepakati nepasi (kazhinji ≤4 MPa).

Mapaipi e3PE ane mukana mukuru wekudzivirira ngura. Maumbirwo awo ane mativi matatu anoita kuti pave ne "kuparadzaniswa kwemuviri + kuchengetedzwa kwemakemikari." Kuongororwa kwemunyu kunoratidza kuti mwero wengura yawo i1/50 chete kupfuura wepaipi yesimbi isina chinhu.Mapaipi eAPIzvinogona kudzivirirwa kubva mukuora kuburikidza nekuisa magasi nekupenda, kushanda kwazvo munzvimbo dzakavigwa kana dziri pasi pemvura kuchiri kwakaderera pane kwemapaipi e3PE, zvichida mamwe masisitimu ekudzivirira cathodic, izvo zvinowedzera mari yepurojekiti.

Maitiro Ekusarudza uye Maitiro Eindasitiri

Kusarudzwa kwepurojekiti kunofanirwa kutevedzera musimboti wekuti "mamiriro ezvinhu akakodzera": Kana nzvimbo yekufambisa iri mafuta kana gasi rine simba rakawanda, kana kuti nzvimbo yekushanda ikasangana nekuchinja kukuru kwekushisa, mapaipi eAPI anosarudzwa, nesimbi dzakadai seX65 neX80 dzichienderana nechiyero chekumanikidzwa. Pakutakura mvura yakasviba kana makemikari, mapaipi e3PE isarudzo inodhura zvishoma, uye ukobvu hwechikamu chekudzivirira ngura hunofanira kugadziriswa zvichienderana nezinga rekuora kwevhu.

Mafambiro ari kuitwa muindasitiri iyi ari pa "performance fusion." Mamwe makambani ari kusanganisa zvinhu zvepasi zve API pombi zvine simba guru nechimiro che 3PE pombi chine mativi matatu chinodzivirira ngura kuti chigadzire "pombi ine simba guru inodzivirira ngura." Mapombi aya anosangana nezvinodiwa zvekutapurirana kwemhepo ine simba guru uye kudzivirira ngura kwenguva refu. Mapombi aya atove achishandiswa zvakanyanya mukugadzira mafuta negasi mugungwa rakadzika uye mapurojekiti ekuparadzanisa mvura pakati pemabheseni. Iyi nzira itsva inopa mhinduro iri nani yekugadzira mapaipi.
