Usati watengahombe-dhayamita yakatwasuka seam simbi mapaipi (LSAW), iwe unofanirwa kutevedzera zvakafanogadzirwa zvakatemwa, kureba, zvinhu, madziro ukobvu, welding zviyero uye weld zvinodiwa, izvo zvinofanirwa kutaurirwa zvakanaka usati watenga.

1. Yekutanga ndiyo tsanangudzo.Semuenzaniso, 800mm inodaidzwa zvakare kuti DN800, kusanganisira 820mm uye 813mm yeA uye B yakatevedzana, kana iyo yekunze dhayamita ye800mm inofanirwa kudiwa zvakajeka kudzivirira kurasikirwa kusingakoshi.

2. Ukobvu hwemadziro ehombe-dhayamita yakatwasuka seam simbi pombi inodiwa kuve 16mm.Zvinogoneka kuti ukobvu chaihwo hwezvigadzirwa zvichave 15.75mm uye 16.2mm, uye pachava nepamusoro kana pasi misiyano.Aya ndiwo maitiro akajairika.Nekuti dzakatwasuka musono mapaipi esimbi ese matani mitengo, zvinodikanwa kutaurirana pachine nguva kudzivirira kusiyana kwehuremu.

3. Kureba kwakajairika kwehombe-diameter yakatwasuka seam simbi pombi ndeye 12m.Apo inoda kugadziriswa, inoda kutaurirwa mberi, nokuti mutengo wehurefu hwakatarwa huchanyanya kudhura.Kana ikasaziviswa pachine nguva, ichave yakareba 9.87m, uye mugadziri anowanzo kupa 9.9m zvakananga.
4. Zvishandiso zvekutenga hombe-dhayamita yakatwasuka seam simbi mapaipi zvinofanirwawo kutaurirwa zvakanaka, uye zvinhu hazvifanirwe kuve OEM.Mukuwedzera, zvinhu zvinofanira kuvimbiswa, uye zvinyorwa zvepakutanga zvesimbi yesimbi zvinofanira kupiwa.Chero matambudziko enyama achadzoserwa uye kubhadharwa.

5. Muyero wekugadzira welding wekugadzira nekugadzirisa unofanirwa kuenderana neatomatiki yakanyura arc welding LSAW GB/T3091-2015, uye chitupa chemhando yechigadzirwa chinodiwa.Kana chiyero chisingaenderane nezvinodiwa, chigadzirwa chinokundikana.
6. Paunenge uchitenga hombe-dhayamita yakatwasuka seam simbi mapaipi, zvinodikanwa kuti utaure pachine nguva nezve mwero we weld flaw yekuona, nekuti weld flaw yekuona inodhura yakawedzera mari.dambudziko.
7. Mukuwedzera, hombe-dhayamita yakatwasuka musono simbi mapaipi pamusoro 1020mm anogona kuburitsa welds maviri.Mapurojekiti mazhinji haagamuchire maviri welds pasina kutaurirana, uye anozodaidzwa akaremara simbi mapaipi.

Nokudaro, zvakakosha kutaurirana zvakanaka nguva isati yasvika musati matenga chero pombi yesimbi, zvichikonzera kukakavara kusingakoshi uye kurasikirwa kwehupfumi.
