Mapaipi esimbi asina madziro akatetepa anoshandiswa zvakanyanya mumaindasitiri nekutengesa zvikumbiro, uye zvinhu zvinonyanya kuzivikanwa zviri 304 uye 316L simbi isina tsvina. Aya masimbi maviri asina tsvina ane yakanakisa corrosion resistance uye mechanical properties uye naizvozvo anosarudzwa sezvinhu zvesarudzo zvepombi dzakatetepa-yakavakirwa simbi isina tsvina. Pazasi ini ndichatsanangura kuti sei kusarudza 304 kana 316L simbi isina tsvina.

Chekutanga, pombi dzesimbi dzisina simbi dzinoda kuve nekudzivirirwa kwakanaka nekuti dzinowanzo shandiswa kutakura midhiya yakasiyana siyana, kusanganisira zvinwiwa, magasi, uye makemikari. 304 Stainless simbi chinhu chakajairika Stainless simbi ine 18% chromium uye 8% nickel. Ichi chemikemikari chinopa 304 simbi isina tsvina yakanakisa kupikisa corrosion, ichiita kuti isarambe kune zvinonyanya kuodza media, zvakaita semvura, acids, uye alkalis. Naizvozvo, 304 mapaipi esimbi isina tsvina anoshandiswa zvakanyanya muindasitiri yakajairika uye minda yekuvaka.

Mukuenzanisa, 316L simbi isina tsvina ine yakakwira corrosion resistance. Iine 2-3% molybdenum, iyo inopa humwe kudzivirirwa kubva pakuora. Izvi zvinobvumira 316L Stainless simbi pombi kuti iite zvakanaka munzvimbo dzakaoma, kunyanya apo chloride ions kana mamwe magasi anoparadza aripo. Naizvozvo, 316L pombi dzesimbi dzisina simbi dzinoshandiswa zvakanyanya mumaindasitiri emakemikari, emugungwa, uye ekugadzira chikafu, ayo ane zvakakwirira zvinodikanwa zvekupokana nekuora.

Chechipiri, pombi dzesimbi dzisina simbi dzinodawo kuve neakanaka emuchina zvivakwa kuti asangane nemhando dzakasiyana dzekushandisa. Ose ari maviri 304 uye 316L simbi isina tsvina ane simba rakanakisa uye kuomarara, zvichiita kuti ive yakakodzera kune mapombi masisitimu munzvimbo dzakanyanya-kudzvanywa uye nepamusoro-tembiricha. Pamusoro pezvo, zvese zviri zviviri zviri nyore kuita muchina uye weld, zvichipa yakakura dhizaini kuchinjika.

Muchidimbu, kusarudzwa kwe304 kana 316L simbi isina tsvina sechinhu chepombi dzakatetepa-yakavakirwa simbi isina simbi yakavakirwa pane kwayo kwakanakisa kushora uye zvivakwa zvemuchina. Zvichienderana nezvinodiwa zvekushandisa uye mamiriro ezvakatipoteredza, kusarudza iyo yakakodzera Stainless simbi zvinhu zvinogona kuve nechokwadi chekuvimbika uye kusimba kwepombi yako system.
