Insait long ol wok olsem baim ol paip, wok konstraksen bilong enjiniaring, bilasim haus, na karim ol kemikel wara, ol paip we i gat 'stainless steel', wantaim ol gutpela samting bilong en olsem ol i no inap bagarap, strongpela, longpela sevis laip, na luk nais, i kamap wanpela bilong ol kain paip we planti manmeri i save yusim. Planti ol manmeri i save baim ol samting, ol enjinia, na ol distributa i save paul long planti kain kain 'stainless steel gred' taim ol i makim ol samting: 201, 304, 316L, 430... Wanem ol samting i narapela long ol dispela kain kain 'stainless steel'? Olsem wanem wanpela i mas makim bihainim 'usage scenario'? Nau, mipela bai lukluk gut long ol bikpela 'stainless steel' paip materiel we i stap long maket, na tok klia long ol pasin, ol samting we i narapela, na ol gutpela wok bilong wanwan kain, na helpim olgeta manmeri long abrusim ol rong long makim ol samting. Ol bikpela steinles stiel paip long maket i gat 4-pela lain: 200 siris, 300 siris, 400 siris, na dupleks steinles stiel. Ol narapela narapela series i no wankain long sait bilong metal komposesen, korosen resistens, magnetism, hai-temperature resistans, prosesing pefomens, na prais, we em ol bikpela samting tu bilong luksave long ol gred.
一. 200 Ol Steinles Stil Paip: Planti Manganese, Liklik Nikel, Em i Gutpela Sois
Ol samting bilong makim: 201, 202
Series 200 em i bilong 'austenitic stainless steel'. Long daunim kos, ol i save yusim 'manganese' long senisim hap bilong nikel, na dispela i mekim em i kamap nambawan 'stainless steel paip' we i no gat bikpela pe tumas long maket. Bihain long ol i wokim long kol, dispela kain paip i save soim liklik 'magnetism'. Strong bilong en long sakim ros em i namel na em i gutpela tasol long ol ples insait long haus we i no gat -korosiv. Ol komon reling insait long haus, ol paip bilong fenija, ol nomol bilas insait long haus, na ol simpol paiplain bilong sotpela taim tasol i save yusim 201 steinles stiel paip.
Ol hevi bilong en i klia tru: em i no inap long sakim sol sprei na ol asid na alkali. Sapos ol i larim i stap ausait, long ol ples klostu long nambis, o long ol faktori we i gat planti wara long en inap longpela taim, em i isi tru long ros na kamapim ol mak long en. Olsem na, em i no gutpela tru long yusim wara saplai na drenej, kemikel, ausait enjiniaring, o ol projek klostu long nambis. Sapos wanpela i no tingting long makim 201 na i no ol gutpela samting bilong baim liklik prais, bihain ol kos bilong lukautim na senisim bai go antap tru.
2. 300 Ol Steinles Stiel Paip: Gutpela Pefomens Olgeta, Maket Mainstrim
300 series em i 'austenitic stainless steel' tu na nau em i nambawan series we planti manmeri i save yusim na i gat gutpela nem. Em i no gat -magnetik, na i gat gutpela strong bilong sakim korosen, strong bilong en, na wok bilong weldim, na ol mak bilong en i gutpela tru.

Dispela em i nambawan gutpela 'food-grade stainless steel we pablik i tingim, wantaim 'scientificly balanced chromium' na 'nickel ratio', gutpela wok bilong en, gutpela tru long sakim bagarap long wara, na em i no inap long kisim 'oxidation' long nomol tempereja. Em i gutpela tru long prosesim, bendim, na weldim.
Wantaim ol pasin bilong en olsem em i seif, i no gat -toksik, na i save stap longpela taim, 304 steinles stiel paip i karamapim bikpela hap bilong ol sivil na jeneral indastriel senario: ol paiplain bilong wara bilong dring, ol paiplain bilong ol masin bilong prosesim kaikai, ol munisipal wara saplai na drenej, ol akitektural dekoresen, ol nomol masin paiplain, na ol narapela samting. drai ausait envairomen, na tu em i namba wan-sois materiel bilong enjiniaring prokiumen.
2. 304L Stainless Steel Pipe (Low Carbon Upgraded Version)
Long 304, mak bilong kabon i go daun. Gutpela samting bilong en em i strongpela wok bilong weldim, na dispela i mekim na em i no inap kisim bagarap long ol 'intergranular corrosion' bihain long em i weldim, na ol weld i no save bruk o ros hariap.
Em i gutpela long ol bikpela paip projek, paip bilong putim wara, na ol longpela paiplain we i nidim bikpela wok long weldim long ples, na dispela i mekim em i gutpela samting long ol wok bilong weldim long indastri.
3. 316 na 316L Steinles Stiel Paip (Hai Korosen-Resisten Vesen)
Tupela samting i gat 'molybdenum', we em i bikpela samting we i narapela long 304. 'Molybdenum' i save strongim paip long sakim ol 'chloride ions', 'salt spray', na 'acid-base corrosion', na dispela i mekim na 'corrosion resistance' bilong en i winim 304, na prais bilong en i antap moa.
Namel long ol, 316L em i 'low-carbon vesen, we i save givim gutpela stebiliti bihain long weldim. Ol dispela kain paip i gutpela tru long ol ples klostu long nambis, wok bilong solwara, trenspot bilong solwara, ol marasin, ol gutpela kemikel, wok bilong klinim pipia wara, na ol narapela ples we i save bagarapim ol samting, na tu ol i save yusim long ol medikel ikwipmen na ol gutpela samting bilong klinim ples. Long ol ples we i gat sol o klorin, we ol i no inap yusim 304, 316L em i gutpela samting.
4. 321 Steinles Stiel Paip (Ol i wokim bilong ol bikpela hat)
Ol i save putim ol samting bilong 'titanium' long dispela samting, pastaim long strongim 'steel structure'. Em inap long holim gutpela wok insait long ol ples we i gat bikpela hat olsem 450 digri i go inap 850 digri, na em inap long sanap strong long taim bilong 'oxidation' na 'intergranular corrosion'.
Em i no strong tumas long sakim asid na alkali, tasol em i save lukluk long hai-temperature resistens, na ol i save yusim moa long ol boiler paiplain, ol 'heat exchanger', na ol indastriel hai-temperature flue gas delivery paiplain, namel long ol narapela hai-temperature aplikesen.
3.400 Series Stainless Steel Pipes: Ferritic / Martensitic, Naturally Magnetic
I no olsem non-magnetik 300 series, 400 series stainless steel em i magnetik olgeta, i no gat nikel long en, i gat liklik pe, na ol i brukim i go long tupela bikpela aplikesen daireksen bihainim pefomens.
1. 430 Stainless Steel Pipe (Gutpela long bilasim na yusim long olgeta de)
Em i bilong 'ferritic stainless steel', em i gat gutpela wok bilong polisim pes bilong en, em i no inap bagarap long ros, na em i no gat bikpela pe bilong en. Strong bilong en long sakim korosen i no strong tumas olsem 304 tasol em i gutpela moa long 201. Ol i save yusim long ol samting bilong haus kuk, ol hap bilong masin, ol nomol paip bilong bilasim haus, na ol ikwipmen we i gat liklik 'nitric acid corrosion'. Em i gutpela long ol samting we i no nidim bikpela strong, lukluk long lukluk na ol samting bilong stopim ros.
2. 409, 410, 420 Stainless Steel Pipes (Heat-resistant, High-strength Versions)
409 i tok moa long strong bilong san na ol i save yusim long ol paip bilong rausim win long ol kar na ol paip bilong ges we i gat liklik hat; 410 na 420 em ol 'martensitic stainless steel' we i gat planti kabon insait long en, we inap long mekim strong na strong bilong en i kamap strong moa long rot bilong hat tritmen, tasol strong bilong ol long sakim korosen i stap namel. Ol dispela kain paip ol i no save yusim long ol paiplain bilong daunim korosen na planti taim ol i save yusim long wokim ol valv, 'shaft', ol hap bilong masin, ol naip, na ol narapela samting we i nidim strong na 'wear resistance'.
5. Kwikpela Materiel Aidentifikesen na Baim Samari
Taim mipela i bungim ol dispela samting antap, mipela i stretim rot bilong baim ol samting long gutpela rot tru bilong helpim olgeta manmeri long inapim ol nid bilong ol hariap:
1.Limited baset, purely indoor dry environment:makim 201, tasol bilong bilasim na ol simpol straksa, i no ken pas wantaim wara o ol samting we i save bagarapim ol samting;
Ol jenerel samting, wara bilong dring, kaikai, enjiniaring oltaim, ol nomol indo na ausait envairomen: namba wan samting 304, long wanem, em i givim gutpela kos-pefomens na pefomens;
2.Ol projek bilong paiplain wantaim bikpela welding:putim 304L i go pas;
3.Ol ples we i gat planti korosen olsem ol ples klostu long nambis, nambis, solwara, kemikel, marasin:go long 316/316L;
4.Ol paiplain we i gat bikpela hat, ol boila, ol samting bilong senisim hat:yusim 321;
Ol samting bilong haus, ol nomol bilas, i no inap bagarap:makim 430;
6.Ol hap bilong masin, hai-temperature eksos, hai-hatnes komponen:yusim 409, 410, 420.
Long kisim ol 'stainless steel' paip, i no gat wanpela gutpela samting tru, tasol i gat gutpela samting tasol. Planti baia i save pundaun isi long trap bilong 'lukluk tasol long prais,' na senisim ol paip we i gat bikpela -dimand wantaim ol samting we i no gat bikpela pe, na dispela i save kamapim ol hevi olsem ros, lik, na wok gen long projek. Sapos yu kliagut long ol bikpela samting we i no wankain namel long ol samting, na tingim ol samting olsem ples we ol i yusim, ol samting we i save bagarap, ol samting we i mas i gat tempereja, na baset, dispela em i wanpela rot tasol long makim ol 'stainless steel' paip we i no gat bikpela hevi, na i no gat bikpela pe, na dispela i daunim ol rot bilong baim na yusim.
