Tsananguro pfupi:

Mapaipi esimbi eLSAW, anoenderana neASTM A252 standards, mapaipi esimbi akasimba uye ane dhayamita hombe akakodzera mainjiniya efaundesheni, kuvaka mabhiriji, mainjiniya emugungwa, uye mapurojekiti ezvivakwa zvinorema. Mapaipi esimbi eLSAW ane chimiro chakanaka kwazvo chekuvaka, anogona kusvetwa zvakanaka, uye kugona kutakura mutoro, zvichiita kuti akwanise kushandiswa pafaundesheni yakadzika. Dhayamita yekunze inotangira pa508 kusvika 1422 mm. Aya mapaipi esimbi eLSAW anoenderana neASTM akagadzirwa zvichienderana nezvinodiwa neindasitiri pari zvino, zvichiita kuti ave nesimba rakawanda, ukobvu hwakaenzana hwemadziro, uye kugara kwenguva refu kunyangwe munzvimbo dzine ivhu rakaoma uye mvura ine munyu.

Mapaipi aya esimbi eLSAW akakodzera nheyo dzemabhiriji, nzvimbo dzechiteshi, mapuratifomu ekunze, nheyo dzezvivakwa dzakakwirira, uye zvivakwa zvemaindasitiri. Kushanda pamwe chete nevakawanda vane ruzivo muEPC uye mhinduro dzekuvaka dzepasi rose dzinoita kuti dzishande kwenguva refu, dzisanyanya ngura (dzine machira ekuwedzera), uye dziri nyore kuisa.

Kushandiswa Kukuru

1. Kuvaka Nheyo (Masisitimu Enheyo Dzakadzika)

Inoshandiswa senzvimbo dzakadzika dzekuvaka zvivakwa zvirefu, mafekitori emaindasitiri, matura ekufambisa zvinhu, nzvimbo dzekutengeserana, uye dzimba dzekugara. Mapombi aya esimbi anopa simba rakasimba rekutakura mutoro uye anovimbisa kugadzikana kwenguva refu kwechivakwa mumamiriro evhu asina kusimba kana akapfava.

2. Bridge Foundation Engineering

Yakanakira mabhiriji emigwagwa mikuru, mabhiriji ezvitima, migwagwa yakakwirira yemumaguta, uye zvivakwa zvinodarika nepakati.ASTM A252 LSAW / EFW simbi dzakaunganidzwaAnoshandiswa zvakanyanya pakuyambuka rwizi, kuyambuka dhamu, uye kuyambuka gungwa, zvichipa simba rakanakisisa rekudzivirira mitoro inoshanduka uye kufamba kwevhu.

3. Kuvaka Zviteshi zvengarava nezvikepe

Inoshandiswa munzvimbo dzinochengeterwa zviteshi, nzvimbo dzekuchengetera makontena, nzvimbo dzekuchengetera ngarava, nzvimbo dzechiteshi, nenzvimbo dzekuisa zvinhu kunze kwenyika. Mapombi aya esimbi akagadzirirwa kutsigira macrane anorema, masisitimu ekutakura zvinhu, uye zvivakwa zvikuru zvegungwa zvine simba rakasimba munzvimbo dzine ngura dzemahombekombe.

4. Simba reMhepo reMhepo yeOffshore & Uinjiniya hweMarine

Inoshandiswa zvakanyanya munheyo dzemhepo dzinoshandiswa pamhepo dziri kunze kwegungwa, mapuratifomu ari kunze kwegungwa, mapaipi egungwa, madziro egungwa, uye zvivakwa zvekudzivirira mahombekombe.Pombi yesimbi yeLSAWMirwi yacho inorwisa zvakanyanya kurova kwemafungu, simba remafungu, uye ngura yemvura yegungwa, zvichiita kuti ive yakakodzera kunzvimbo dzakaoma dziri mugungwa.

5. Mapurojekiti Makuru Einjiniya Yezvivakwa

Inoshandiswa mumadhamu, zviteshi zvepasi pevhu, matuneri, zvivakwa zvekuchengetedza, uye mapurojekiti makuru ezvivakwa zvinoda rutsigiro rwakadzika rwenheyo. Makomba aya anokwanisa kutakura mitoro inorema yemidziyo yeindasitiri uye mamiriro akaomarara ekugadzirisa.

3) Inoongororwa nemasangano ane chiremera akadai seCCIC, SGS, BV, uye TUV, ine mapurasitiki akajairika anokodzera kufamba mugungwa

Kurongedza Uye Kutumira

1 Kurongedza:Mabhande esimbi ekubata zviri nyore. Mabhuroko emapuranga kana dunnage anoiswa pakati pemaburi emiti kudzivirira kuchinja kwenhengo panguva yekutakura. Kugadzirisa pamusoro (sarudzo): Pendi nhema, mafuta ekudzivirira ngura, firimu repurasitiki. Mapombi egirazi anonyudzwa mumvura inopisa anogona kuputirwa nefirimu rekudzivirira kwenguva pfupi kudzivirira kukwenya pamusoro. Mapakeji akagadzirwa anogona kupihwa.

2 Kutumirwa:Kureba kwemidziyo yakajairika: 6m, 12m. Inowanikwa muhurefu hwakasiyana. Inouya neSea Rail neRoad Applicable. Inokodzera kutakura zvinhu mugungwa, njanji kana mugwagwa. Nguva yekutumira inowanzo kuve mazuva 15-30 mushure mekugamuchira muripo, zvichienderana nehuwandu uye zvakatsanangurwa. Inokodzera kutengeswa kunze kwenyika pasi rese, ine gwaro rakazara (chitupa chekuongorora, runyorwa rwekurongedza, bhiri rekutakura zvinhu).

3 Nzira dzekudzivirira pakubata:Usashandise zvirauro kana zvikorekedzo zvisina mapedhi kuti zvishande zvakananga pamusoro pepombi kudzivirira kuti pombi isakanganiswe. Chengeta munzvimbo inotonhorera, yakaoma uye ine mhepo yakanaka, dzivisa ngura usati waisa. Kutumira zvinhu zvakakura uye zvinorema zvakanyanya ndapota tevedzera mitemo yekutumira zvinhu munharaunda.

Mibvunzo Inowanzo bvunzwa

1. Mashandisirwo emapaipi esimbi eASTM A252 Giredhi 3?

Mapaipi esimbi eASTM A252 Giredhi 3 LSAW anonyanya kushandiswa pakuumbwa kwenheyo dzakadzika mumabasa ekuvaka, akadai sezvivakwa, mabhiriji, zviteshi zvengarava, mahombekombe nezvimwewo.

2. Giredhi 1, Giredhi 2 neGiredhi 3 zvakasiyana sei?

Inopa simba rakanakisisa uye kugadzikana kwemagiredhi matatu, saka yakakodzera nheyo dzinorema, uye mainjiniya egungwa.

3. Chii chinonziChubhu yesimbi yeLSAW?

Yakagadzirwa kubva paruzivo rwehunyanzvi hwesimbi, LSAW pombi chigadzirwa chepombi chinogadzirwa nekugadzira uye kusanganisa maplate esimbi kwenguva refu, ayo anonziwo "longitudinal weld steel pipe".

4. Zvikuru sei uye ukobvu hupi huripo?

Dhayamita dziripo mbiri dzinosiyana pahukuru kubva paOD 406 mm kusvika 2500 mm uye ukobvu hwemadziro hunobva pa6 mm kusvika 60 mm dzinoshandiswa pakuvaka hwaro hunorema uye mabasa ekuvaka egungwa.

5. Inogona kushandiswa mumapurojekiti egungwa nekunze kwenyika here?

Ehe. Inowanzoshandiswa mumagetsi emhepo ari kunze kwegungwa, mumadziro egungwa, mumadoko, uye mumapuratifomu egungwa, pakati pezvimwe. Ine machira anosanganisira epoxy, 3PE, simende yekudzivirira ngura.
