Kuvandudza Incastture Kubudirira neS355 JR Spiral Steel Pipi: Iyo Chandende yeGame yeMavhesi Anosikwa Gasi Popeline Kuvaka
Nhungamidzo:
Kukura kuri kuwedzera kwesimba rakanyatsogona uye rakavimbika rave kuita hanya kwakakosha kwehurumende uye maindasitiri pasi rese. Sezvo masikirwo egasi akasikwa ari maArteries echisimba gasi yekufambisa, pombi yekushambadzira kwekusarudzwa kwakakosha kuti uve nechokwadi chekusanzwisisika uye kusimba simba. Mune iyi blog, isu tinoongorora kuti S355 JR Spill Steel pombi, inozivikanwawo seMucherechedzo weEAM PIPE.

Hydrostatic test
Kureba kwepepe kuchaidzwa nemugadziri kune hydrostatic kumanikidza kuchagadzira madziro kushushikana kwekushaiwa makumi matanhatu muzana yeiyo yakasarudzika shuwa simba rekubereka tembiricha. Dzvinyiriro ichatsanangurwa neiyo inotevera equation:
P = 2st / d
Zvinotenderwa kusiyana kwehuremu uye zviyero
Kureba kwega kwega kwepepe kucharemerwa zvakasiyana uye kurema kwayo hakuzopindiri kupfuura gumi muzana pamusoro kana 5.5% pasi pehuremu hwayo uye huremu hwayo uye huremu hwayo pane urefu hwakareba

1. Nzwisisa S355 JR Spiral Steel pombi:
S355 JR Spiral Steel PipiYakagadzirwa neyekumusoro-giredhi simbi uye iri spiral seam pipe inonyanya kugadzirwa kune gasi pombi yekuvaka yekuvaka. Iyo spiral seam chimiro inopa pombi yakanaka kwazvo simba uye kuchinjika, ichiita kuti ive yakakodzera kutapurirana kwenguva refu uye kufambisa kwegasi kwechisikigo. Robusnness yavo inovimbisa kudzikisira kune zvinhu zvekunze senge kufamba kwepasi, chiitiko cheSilis uye chocoros, nokudaro chinoita kuti utsinye uye kutendeseka kweiyo gasi yepombi yemapipi.
2. Chekutanga Chekutanga:
Kuvimbika uye kuchengetedzwa kweyechisikigo gasi mapipi akakosha kune hutano hwepamoyo nenharaunda. Simba repamusoro uye kusimba kweS355 JR Spiral Steel pombi iri basa rakakosha basa mukuderedza njodzi yekukora, kupwanya uye tsaona dzinotevera. Nekuda kwekuvaka kwayo kweSeam Seam, kutendeka kwePIPE kunoramba kwakasimba kunyangwe munzvimbo yakaoma kana mamiriro ekunze ekunze. Kubatanidza pombi iyi mune yakasikwa gasi pombi yemapipi inodzora mukana wekuti njodzi dzezvakatipoteredza uye dzinobvumira kuyerera kweganda rechisikigo kuti vapedze vashandisi.
3. Kugara kwezvinhu zvinosiririsa zvinhu:
Iyo yepamusoro durability yeS355 JR Spiral Steel pombi inovimbisa huwandu hwenzvimbo yako yegesi yemapipi, inochengetedza mari yekutsiva nekutsiva kwenguva. Iyo pombi yakagadzirwa neyekumusoro-giredhi simbi, iyo ine yakanakisa kupesana, kukanganisa kuramba uye kupfeka kuramba. Kupokana uku kunodzora kugadziriswa uye kutsiva, nekudaro kuderedza maitiro ezvemamiriro ekunze uye kabhoni emapisoni inosanganiswa neyepombi yekuchengetedza uye kuvakazve. Hupenyu hwakawedzerwa hwekutenderera kweS355 JR Spiral Steel pombi zvakananga zvinopa kune yakawedzera uye ine hushamwari gasi gasi pombi yepipi.
4. Kuvandudza Kufambisa Kubudirira:
Kubudirira mune zvakasikwa gasi rekufambisa kunosanganisira kuderedza kurasikirwa kwesimba uye kuwedzera simba rekutapurirana. Iyo spiral seam chimiro cheS355 JR Spiral Steel pombi inobvumira kutsiga, inogara ichitsvuka, kuderedza kurasikirwa kwekurasikirwa uku uchiwedzera iyo pombi yekufambisa yePIPELING. Iyo pombi ine yunifomu yemukati yemukati iyo inovimbisa yakajeka inoyerera masimba masimba, nokudaro achideredza kushandiswa kwesimba uye kuwedzera kugona. Pamusoro pezvo, iyo yePIPE's Lightweight isisiki inoita kubata, kutakura uye kuisirwa nguva yakawanda inokwanisa, inochengetedza panguva yekuvaka.
Mhedziso:
Kusanganisira s355 JR Spiral Steel Pipi muzvisikwa Gasi Pepa rekuvaka rakaratidzwa kuti uvandudze kugona kwakazara. Simba rePIPELECE SIMBASA, Durability uye yekuchengetedza zvinhu zvinoumba kuyerera kusevha kwegasi kwechisikigo, kuderedza njodzi yengozi, njodzi dzematambudziko uye mari yekugadzirisa. Nekutarisa kwekutakura kugona uye kuderedza kurasikirwa kwesimba, pombi inobatsira mukusangana kwekukura kwesimba kugombedzera maitiro anowedzera. Kudyara mumhinduro dzinosimudzira senge sjekiti yesimbi yakakosha kuhurumende, indasitiri uye nharaunda yekupa simba rakavimbika uye kugadzirira nzira yeramangwana renyama yakachena.
