Kuputira
Isu hatingope vatengi vedu mapaipi esimbi emhando yepamusoro eX70 chete asiwo tinopa marudzi akasiyana-siyana emabasa ekuputira kuti tigutse zvinodiwa nemapurojekiti akasiyana.
Kupenda mapende: Mapendi echinyakare anopa dziviriro huru kubva mukuora uye akakodzera nzvimbo dzisiri dzakanyanya kana dziviriro yenguva pfupi.
Kuputira kweFBE: Inoiswa pamusoro pepombi yesimbi nekupfapfaidza nemagetsi uye yozopedzwa nekupisa. Kuputira uku kunodzivirira makemikari nekukwesha uye kwakakodzera mapaipi epasi pevhu kana epasi pemvura.
Kuputira kwe3LPE: Yakagadzirwa ne epoxy coating, namatidziro, uye polyethylene layer, inopa kudzivirira ngura kwakanaka uye kudzivirira michina kune akasiyana-siyana mapombi ekutakura pasi pevhu.
Kuputira kwe3LPP: Kufanana ne3LPE, chifukidziro che3LPP chine zvikamu zvitatu, asi chinoshandisa polypropylene sechikamu chekunze. Chifukidziro ichi chinodzivirira kupisa zvakanyanya uye chakakodzera kupombi munzvimbo dzinopisa zvakanyanya.
Mapendi anogona kusarudzwa zvichienderana nemamiriro chaiwo ekushandiswa uye zvinodiwa zvepaipi kuti ive nechokwadi chekuvimbika uye kuchengetedzeka kwemapaipi eAPI 5L X70 panguva yekushandiswa.
Zvikonzero Zvokuti Tisarudze Pombi Yesimbi yeX70
1. Mafekitori ane chitupa cheAPI 5L: Mafekitori edu ane chitupa cheAPI 5L, icho chinovimbisa mwero wepamusoro kubva panobva chigadzirwa kusvika chapera nemutengo wakaderera.
2. Mhando dzakawanda dzemapaipi: Isu hatisi vagadziri vemapaipi esimbi akasungirirwa chete asiwo tiri vagadziri vemapaipi esimbi asina musono, uye tinogona kupa mhando dzakasiyana dzemapaipi anogona kusangana nezvinodiwa zvemapurojekiti akasiyana.
3. Midziyo yese inotsigiraPamusoro pemapaipi esimbi, tinogonawo kupa maflange, magokora, nezvimwe zvishandiso zvinotsigira, zvichipa mhinduro dzekutenga imwe chete yepurojekiti yako.
4. Basa rakagadzirirwa: Tinokwanisa kupa mhinduro dzakagadzirwa zvinoenderana nezvinodiwa nevatengi, kusanganisira kugadzirwa uye kugadziriswa kwemapombi esimbi ane hunyanzvi hwakakosha.
5. Mabasa ehunyanzviKubva payakavambwa muna 2014, kambani iyi yave ichishanda mumapurojekiti akawanda einjiniya uye yakaunganidza ruzivo rwakakura muindasitiri iyi, zvichiita kuti ikwanise kupa mabasa nerutsigiro rwakakosha.
6. Kukurumidza kupindura nekutsigira: Chikwata chedu chekubatsira vatengi chinogona kupa mhinduro nekukurumidza uye rutsigiro rwehunyanzvi hwehunyanzvi kuti tive nechokwadi chekuti matambudziko ako nezvaunoda zvagadziriswa nenguva.
