Pipe Yakasungirirwa Yemusono Welded Pombi GBT9711 2011PSL2

Tsananguro pfupi:

Mumunda wepombi yemafuta negasis, kushandiswa kwemapombi espiral welded kuri kuramba kuchiwanda. Anozivikanwawo segas line pipe, saw pipe, uye oil and gas pipe, mapombi aya anoshanduka-shanduka akagadzirwa achishandisa matekiniki akasiyana ewelding anopa mabhenefiti akawanda mukufambisa oiri, gasi rechisikigo, nezvimwe zvinwiwa. Mublog rino, tichaongorora kushanduka-shanduka kwemapombi espiral welded uye kuti nei ari iwo sarudzo yekutanga kumapurojekiti mazhinji epombi.

Chimwe chezvakanakira zvikuru zvepombi yedu yakasungirirwa nemusono wespiral isimba rayo risingaenzaniswi uye kugara kwenguva refu. Kushandiswa kwesimbi dzemhando yepamusoro kunoita kuti pombi dzedu dzikwanise kutsungirira mamiriro akaipisisa uye mitoro inorema, zvichiita kuti dzikwanise kushandiswa zvakasiyana-siyana. Kubva pakutumira mafuta negasi kusvika kumagetsi emvura netsvina, pombi dzedu dzinovimbisa kushanda kwakavimbika uye basa rinogara kwenguva refu.

Pamusoro pezvo, mapaipi edu esimbi akasungirirwa netambo dzesimbi dzemhando yepamusoro anopa hunyanzvi hwakasiyana-siyana. Nekukwanisa kugadzira mapaipi esimbi ane dhayamita hombe, tinogona kusangana nezvinodiwa zvakasiyana-siyana zvepurojekiti uye zvirevo. Kunyangwe muchida mapaipi ekuvandudza zvivakwa, mapurojekiti ekuvaka kana mashandisirwo emaindasitiri, tine hunyanzvi hwekusangana nezvinodiwa zvenyu.

Pamusoro pekusimba uye kushanduka-shanduka, mapaipi edu akasungirirwa nemusono we spiral anopa kudzivirira ngura kwakanyanya. Izvi zvakakosha, kunyanya mumaindasitiri anowanzo sangana nemamiriro ekunze akaomarara nezvinhu zvinoparadza. Mapaipi edu akagadzirwa kuti agare kwenguva refu, zvichiita kuti ashande zvakanaka kunyangwe mumamiriro ezvinhu akaomarara.

KuCangzhou Spiral Steel Pipes Group Co., Ltd., takazvipira kupa zvigadzirwa zvemhando yepamusoro uye sevhisi yakanaka kune vatengi. Matanho edu ekudzora mhando uye maitiro ekuyedza akaomarara anoita kuti pombi yega yega yakasungirirwa musono inobuda mufekitori isvike padanho repamusoro-soro reindasitiri. Pamusoro pezvo, timu yedu yekutsigira vatengi yakatsaurirwa iri pano kuti ikubatsire nemibvunzo kana zvinokunetsa zvaungave nazvo.

Zvose pamwe chete, mapaipi edu espiral seam welded imhinduro yakavimbika uye inoshanda kune akasiyana mashandisirwo. Kuburikidza nemaitiro edu ekugadzira emazuva ano uye kuzvipira kuita zvakanaka, tava mutengesi anovimbwa muindasitiri iyi. Kunyangwe uri kutsvaga simba, kushanduka-shanduka kana kuramba ngura, mapaipi edu espiral seam welded ndiyo sarudzo yakakodzera. Sarudza Cangzhou Spiral Steel Pipes Group Co., Ltd. kune zvese zvaunoda pamapaipi esimbi.
