4. Cov qauv: Cov kav dej thiab cov kav dej tuaj yeem tsim tau rau ntau yam qauv thoob ntiaj teb, suav nrog ASTM, EN, thiab ASME.

5. Qhov kawg tiav: Cov kav dej thiab cov raj tuaj yeem muab tau nrog ntau qhov kawg ntawm qhov kawg, nrog rau qhov kawg kawg, beveled kawg, thiab threaded kawg.

6. Nto tiav: Cov kav dej thiab cov raj tuaj yeem muab tau rau hauv ntau qhov chaw ua tiav, suav nrog 2B, BA, No. 4, thiab No. 8.

7. Kev ntsuam xyuas thiab ntawv pov thawj: Cov kav dej thiab cov kav dej yuav raug rau ntau yam kev ntsuas kev tswj xyuas kom ntseeg tau tias lawv cov khoom siv kho tshuab, kev tiv thaiv corrosion, thiab tag nrho cov khoom zoo. Cov kev ntsuam xyuas no suav nrog kev kuaj hydrostatic, kuaj ultrasonic, thiab kuaj cov khoom. Raws li kev thov, cov kav dej thiab cov kav dej tuaj yeem muab tau nrog kev tshuaj xyuas thiab ntawv pov thawj thib peb.

Duplex stainless hlau tau pom dav siv nyob rau hauv kev lag luam uas yuav tsum tau muaj zog thiab corrosion kuj. Nws cov ntawv thov sib txawv ua rau nws muaj txiaj ntsig zoo rau ntau yam kev lag luam:

Kev lag luam roj thiab roj

Kev lag luam tshuaj

Kev lag luam marine

Kev lag luam kev tsim kho

Kev lag luam zaub mov thiab dej haus

1. Corrosion Resistance: Duplex steel kav thiab cov raj muaj kev tiv thaiv corrosion zoo heev, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav thiab corrosive. Lawv cov qauv ob-theem muab kev tiv thaiv zoo tshaj plaws rau kev ntxhov siab corrosion cracking, pitting, crevice corrosion, thiab dav corrosion.

2. Lub zog: Duplex steel muaj zog ntau dua li cov pa austenitic thiab ferritic stainless hlau. Qhov no tso cai rau cov phab ntsa nyias nyias thiab me me, uas tuaj yeem txuag tau cov nqi ntawm cov khoom siv thiab kev ua haujlwm.

3. Kev Tiv Thaiv Kev Kub Kub thiab Kev Kub Siab: Duplex steel kav thiab cov raj muaj kev tiv thaiv siab rau ob qho tib si kub thiab siab, ua rau lawv tsim nyog siv rau hauv cov ntawv siv high-pressure xws li kub exchangers, boilers, thiab siab hlab ntsha.

4. Tsawg Thermal Expansion: Lub thermal expansion coefficient ntawm duplex steel yog qis dua lwm yam hlau xws li carbon steel thiab austenitic stainless hlau. Qhov no ua rau duplex steel kav thiab cov kav dej ruaj khov thiab tsis tshua muaj kev cuam tshuam txog cov teeb meem thermal expansion.

Qhov sib txawv tseem ceeb ntawm duplex steel thiab super duplex steel yog nyob rau hauv lawv cov muaj pes tsawg leeg thiab cov khoom. Super duplex steel yog qhov tseem ceeb ntawm cov hlau ntau dua ntawm duplex steel uas muaj ntau cov chromium, molybdenum, thiab npib tsib xee. Qhov no ua rau kev txhim kho corrosion kuj, muaj zog dua, thiab ntau dua rau kev ntxhov siab corrosion cracking.

Loj: ½ "mus rau 48" inch thiab mus txog 40 ko taw ntev.

Ntev: 5 mus rau 7 meters los yog ntev raws li cov neeg siv khoom xav tau.

Xaus kev sib txuas: threaded, beveled, tiaj, flanged, los yog grooved.

Deg tiav: dub, galvanized, pleev xim rau, los yog coated nrog epoxy, polyethylene, los yog polyurethane. Qhov saum npoo tiav yog raws li qhov xav tau ntawm corrosion kuj, zoo nkauj, thiab durability.

Hauv kev xaus, SSM qhov kev txawj ntse hauv kev tsim thiab muab Duplex Steel Pipes hauv Suav teb ua rau lawv muaj kev ntseeg siab rau ntau yam kev lag luam uas xav tau cov kav dej zoo. Nrog rau lawv txoj kev cog lus los muab cov khoom tshwj xeeb thiab cov kev pabcuam, SSM ua kom cov neeg siv khoom txaus siab thiab tsim kev sib raug zoo nrog lawv cov neeg siv khoom ntev. Txawm hais tias rau cov roj thiab roj av, kev ua tshuaj lom neeg, lossis lwm yam kev siv, SSM's Duplex Steel Pipes yog cov kev daws teeb meem saum toj kawg nkaus rau cov kav dej xav tau.

Q: Qhov txawv ntawm 316 thiab duplex yog dab tsi?

A: Duplex muaj lub zog ntau dua thiab zoo dua corrosion dua li 316 stainless hlau, ua rau nws haum rau siv nyob rau hauv ib puag ncig hnyav xws li offshore roj rigs thiab tshuaj ua cov nroj tsuag.

Q: Puas yog 316L yog duplex steel?

A: 316L yog qhov sib txawv ntawm 316 stainless hlau nrog cov ntsiab lus qis dua, uas ua rau nws tiv taus ntau dua rau kev nkag siab thiab corrosion tom qab. Txawm li cas los xij, 316L tsis yog cov hlau duplex.

Q: Dab tsi yog qhov sib txawv ntawm duplex steels?

A: Lean duplex stainless hlau, Standard duplex stainless hlau, thiab Super duplex stainless hlau.
