Mabhenefiti eA252 Grade 2 Steel Pipe Spiral Submerged Arc Welded Polypropylene Lined Pipe

Zvakanakira zveA252 Grade 2 Steel Pipe Spiral Submerged Arc Welded Polypropylene Lined Pipe Mufananidzo Unoratidza

Tsananguro pfupi:

Munyika dzemaindasitiri, kushandiswa kwemapombi ane polypropylene kuri kuramba kuchifarirwa nekuda kwezvibatsiro zvawo zvakawanda mukushandiswa kwakasiyana-siyana. Muindasitiri yekuvaka, kushandiswa kwemapombi esimbi echipiri eA252 isarudzo yakajairika kumapurojekiti mazhinji. Pamusoro pezvo, nzira yekuwelda ye spiral inopinda mu arc inowanzo shandiswa kubatanidza mapombi aya esimbi pamwe chete kuti agadzire sisitimu yepombi yakasimba uye inogara kwenguva refu.

Pombi yepolypropylene yakaputirwaine zvakanakira zvakawanda kana ikashandiswa pamwe chete ne spiral submided arc welding ye A252 Grade 2 steel pipe. Chimwe chezvakanakira zvikuru i corrosion resistance inouya ne polypropylene. Nekufukidza steel pipe ne polypropylene, mukati mepombi inodzivirirwa kubva kuzvinhu zvinoparadza, zvichiita kuti pombi igare kwenguva refu uye yakavimbika. Izvi zvinonyanya kukosha mukushandiswa uko mapaipi ari kusangana nemakemikari akaomarara kana mamiriro ekunze.

Pamusoro pezvo, mapaipi ane polypropylene anozivikanwa nepamusoro pawo pakanaka, izvo zvinobatsira kuderedza kukweshana uye kuwedzera kuyerera kwemvura mumapaipi. Izvi zvinowedzera kushanda zvakanaka uye zvinoderedza kushandiswa kwesimba, zvichiita kuti ive sarudzo inokwezva kune akasiyana mashandisirwo emaindasitiri nemabhizinesi.

Imwe mukana mukuru wekushandisa pombi dzakagadzirwa nepolypropylene mu spiral intensive arc welding ndeyekuwedzera dziviriro kubva pakusakara. Polypropylene lining inoshanda sechidziviriro, ichidzivirira pombi dzesimbi kubva mukukuvadzwa uye ichideredza kudiwa kwekugadzirisa nekugadzirisa nguva nenguva.

Pamusoro pezvakanakira zvinopihwa ne polypropylene lining, maitiro ekubatanidza spiral immersed arc welding chinhu chakakosha pakugadzira sisitimu yemapaipi yakasimba uye yakavimbika uchishandisaPombi yesimbi yeA252 Giredhi 2Tekinoroji iyi yekushongedza inoshandisa nzira yekushongedza ye arc ine flux-core iyo inogadzira welds dzakasimba uye dzakapfava dzinosangana nezvinodiwa zvepaipi dzeindasitiri.

Simba uye kusimba kwehurongwa hwemapaipi kunowedzerwawo nekushandisa mapaipi ane welded maviri akagadzirwa ne spiral submerged arc welding. Mapaipi aya akagadzirwa kuti agone kutsungirira kumanikidzwa kwakanyanya uye kupa mashandiro kwenguva refu, zvichiita kuti ave sarudzo yekutanga kune akasiyana mashandisirwo.

Muchidimbu, kusanganiswa kwepombi dzakagadzirwa nepolypropylene ne spiral submerged arc welding yepombi yesimbi yeA252 Grade 2 kunopa mabhenefiti akawanda kune masisitimu emapaipi emaindasitiri. Kubva pakuramba ngura uye kuderedza kukweshana kusvika pakudzivirira kubva pakusakara, zvikamu izvi zvinoshanda pamwe chete kugadzira mhinduro dzinoshanda uye dzakavimbika dzemapaipi. Sezvo maindasitiri achiramba achitsvaga zvinhu zvinoshanda uye matekiniki ekuvaka, kushandiswa kwepombi dzakagadzirwa nepolypropylene ne spiral submerged arc welding pasina mubvunzo kucharamba kuri sarudzo yekutanga kune akawanda mashandisirwo.
