Zvakanakira Kushandisa Pombi yePolyurethane Lined muDouble Submerged Arc Welded (DSAW) EN10219 Mashandisirwo eMapaipi

Chekutanga,pombi yakagadzirwa nepolyurethaneinozivikanwa nekusapfeka zvakanaka uye ngura. Rutivi rwepolyurethane runoshanda sechidziviriro, runodzivirira mukati mepombi kuti isasvibiswe nechinhu chinoputika nepaipi. Izvi zvakakosha zvikuru mukushandiswa kwepombi dzeDSAW EN10219 sezvo pombi dzinowanzo sangana nemvura inomhanyisa uye zvidimbu zvakasimba. Nekushandisa pombi dzakagadzirwa nepolyurethane, makambani anogona kuderedza zvakanyanya kuwanda kwekugadzirisa nekugadzirisa kunodhura, zvichikonzera kuchengetedza mari yakawanda munguva refu.

Pamusoro pezvo, mapaipi ane polyurethane anopa kuchinjika kwakanyanya uye kugara kwenguva refu zvichienzaniswa nezvimwe zvinhu zvepaipi. Maitiro ekuwelda arc akadzika kaviri anoshandiswa kugadzira mapaipi eEN10219 anoita kuti pave nechimiro chepaipi chisina musono uye chakasimba. Pamwe chete nehunhu hunochinjika uye hunochinjika hwepolyurethane, sisitimu yemapaipi inobuda inokwanisa kutsungirira tembiricha yakanyanya uye mitoro inorema, zvichiita kuti ive yakakodzera kushandiswa mumaindasitiri. Kusanganiswa uku kwesimba uye kuchinjika ndicho chikonzero chikuru nei mapaipi ane polyurethane ari sarudzo yekutanga yeDSAW EN10219 pombi.

Pamusoro pehunhu hwadzo hwepanyama, mapaipi ane polyurethane anorumbidzwawo nekuda kwekubatsira kwadzo nharaunda. Mapaipi ane polyurethane haana makemikari, zvichireva kuti haazobatikane nezvinhu zviri kutakurwa nemapaipi. Izvi hazvingobatsiri chete kuchengetedza kuchena kwezviri mukati, asi zvinodzivirirawo zvinhu zvinokuvadza kuti zvisaburitswe munzvimbo nharaunda. Sezvo mitemo yezvakatipoteredza ichiramba ichioma, kushandisa mapaipi ane polyurethane kunogona kubatsira makambani kuona kuti anotevedzera mitemo iyi uye kuderedza kukanganiswa kwezvakatipoteredza.

Chekupedzisira, mapaipi ane polyurethane anozivikanwa nekureruka kwawo pakuaisa nekugadzirisa. Kugadzirwa kwakanaka kwemapaipi eDSAW EN10219 pamwe chete nehunhu hwakareruka hwepolyurethane kunoita kuti kuiswa kuve nyore uye nekukurumidza. Pamusoro pezvo, pamusoro pemukati pe polyurethane liner panoderedza kuunganidzwa kwesedi uye kunoderedza kukweshana, zvichikonzera kuyerera kwakanaka uye kushandiswa kwesimba shoma. Izvi zvinoreva kudzikira kwemitengo yekushanda uye kugadzirwa kwepamusoro kwemaindasitiri kunoenderana nemapaipi eDSAW EN10219.

Muchidimbu, zvakanakira mapaipi ane polyurethane zvinoita kuti ive sarudzo yakanaka yekushandisa mapaipi ane arc welded ane arc EN10219 kaviri. Kusapera kwavo uye kuramba ngura, kuchinjika uye kugara kwenguva refu, hushamwari hwezvakatipoteredza, uye nyore kuisa nekugadzirisa zvinoita kuti ave pombi dzinosarudzwa munzvimbo dzakaoma dzemaindasitiri. Sezvo tekinoroji ichiramba ichifambira mberi uye mwero weindasitiri uchichinja, tinotarisira kuona kuvimba kwakanyanya nemapaipi ane polyurethane mumakore anotevera.
