Suma:
Mubasa rekugadzira mapaipi, kufambira mberi kwetekinoroji kwakagadzira nzira yesarudzo dzakasiyana siyana dzekusangana nezvinodiwa zvemaindasitiri. Pakati padzo, SAWH tube (spiral submerged arc tube) yakagamuchirwa nekutariswa kukuru uye kukosheswa. Nhasi, tichaongorora mabhenefiti akawanda ePombi yeSAWH, ichijekesa zvirevo zvayo, mashandisirwo ayo uye mhedzisiro yayo pamaindasitiri pasi rese.
1. Nzwisisa SAWHpombi:
Pombi yeSAWH, inozivikanwawo sepombi yesimbi yakanyudzwa mumvura, imhando yakasarudzika yemapaipi esimbi anogadzirwa uchishandisa tekinoroji ye spiral welding. Maitiro acho anosanganisira kugadzira coil yesimbi inoputirwa nekupisa kuita spiral wozoiisa pasi pe arc welding pamusoro pemukati nekunze. Mugumisiro wacho ipaipi yakasimba uye isingadhuri ine chimiro chakanaka.
2. Zvakanakira zvekuvaka:
Mapaipi eSAWH ane zvakanakira zvakawanda zvekuvaka, zvichiita kuti ave sarudzo yakanakisa kumaindasitiri akasiyana-siyana. Tekinoroji yekubatanidza inotenderera inoita kuti pombi yese ive nehukobvu hwakaenzana, nokudaro ichisimbisa simba rayo. Pamusoro pezvo, nzira iyi yekubatanidza inogona kugadzira mapaipi akakura, izvo zvinobatsira pakutakura zvinhu zvakawanda kure. Aya mapaipi ane dhayamita hombe anoita basa rakakosha mukuvandudzwa kwezvivakwa zvakaita sekuvakwa kwemapaipi emafuta negasi.
3. Kushandiswa kwakakura:
Kushanda kwemapaipi eSAWH kwakasiyana-siyana kunoonekwa mukushandiswa kwawo kwakasiyana-siyana. Mapaipi aya anowanzo shandiswa kutakura mvura negasi, zvichiita kuti ave chikamu chakakosha chemaindasitiri akadai semafuta negasi, nzvimbo dzekuchenesa mvura, uye masisitimu etsvina. Kusagona kwayo ngura zvakanyanya uye kugona kwayo kutsungirira mamiriro ekumanikidzwa kwakanyanya kunoita kuti mapaipi eSAWH akwanise kushandiswa pakuchera mafuta kunze kwenyika uye pakutsvaga mvura yakadzika.
4. Kubudirira kwemutengo:
Kufunga nezvemitengo kwakakosha mumaindasitiri mazhinji uye mapaipi eSAWH anopa mhinduro isingaenzaniswi kana tichitarisa kukwanisika kwemari. Maitiro ekugadzira mapaipi eSAWH anowedzera kubereka kana tichienzanisa nedzimwe nzira dzekugadzira mapaipi, nokudaro zvichideredza mari yekugadzira. Pamusoro pezvo, kugara kwavo kwenguva refu uye zvinodiwa zvekugadzirisa zvishoma zvinoita kuti zvive imwe nzira inodhura zvishoma pane zvimwe zvinhu zvepaipi nekufamba kwenguva.
5. Kufunga nezvezvakatipoteredza:
Sezvo matambudziko ezvakatipoteredza ari kuramba achikura, maindasitiri ari kutsvaga mhinduro dzinogara kwenguva refu. Nerufaro, mapaipi eSAWH anosangana nezvinodiwa izvi nekuti anogadzirwa nesimbi yepamusoro-soro, inogona kushandiswazve, zvichideredza kukanganiswa kwekabhoni. Uyezve, kugara kwawo kwenguva refu uye kuramba ngura zvinoderedza kudiwa kwekutsiviwa nguva nenguva, zvichiwedzera hupenyu hwawo hwese uye zvichideredza marara.
Mukupedzisa:
Mapaipi eSAWH kana mapombi esimbi akadzika midzi akachinja indasitiri yekugadzira mapaipi. Zvakanakira magadzirirwo awo, kushandiswa kwakasiyana-siyana, kushandiswa kwemari shoma uye zvakanakira nharaunda zvinoita kuti ave sarudzo yakakurumbira mumaindasitiri akasiyana-siyana. Sezvo maindasitiri aya achiramba achikura, kudiwa kwemapaipi eSAWH pasina mubvunzo kuchawedzera, zvichiita kuti mvura nemagasi zvifambiswe zvakanaka uye zvinogara kwenguva refu mumakore anotevera.
