Qib Kev Sib Piv Ntawm Stainless Hlau Yeeb Nkab Fittings (201 / 430 / 304 / 316L)

 

Tsab ntawv xov xwm no sib piv plaub lub ntsiab stainless hlau yeeb nkab haum qib hauv ntiaj teb kev lag luam txawv teb chaws los ntawm tsib qhov loj me: tus nqi, kev tiv thaiv corrosion, kev lag luam siv tau, kev pab cuam lub neej thiab kev ua haujlwm, los pab cov neeg siv khoom txawv teb chaws xaiv cov khoom sib txuam kom raug.

1. Nqe sib txawv

Muab faib los ntawm tus nqi qis rau tus nqi siab: 201 < 430 < 304 < 316L

201 stainless hlau yeeb nkab fittings: Txais qis-nickel siab-manganese formula, tus nqi qis tshaj plaws ntawm txhua qib, nyob ib ncig ntawm 35% -42% pheej yig dua li tus qauv 304. Nws tus nqi tsis tshua hloov pauv nrog tus nqi npib tsib xee thoob ntiaj teb, haum rau loj - cov peev txheej hauv tsev piping.

430 ferritic stainless hlau yeeb nkab fittings: Nickel- cov khoom siv dawb, nqe 20%–28% qis dua 304, ruaj khov hais txhua xyoo tsis muaj nqi npib tsib xee, zoo tagnrho rau cov kav dej hauv tsev qhuav.

304 austenitic stainless hlau yeeb nkab fittings: Ntiaj teb no kev lag luam benchmark qib nrog pob tshab pricing, 18% -25% pheej yig dua premium 316L. Tus nqi hloov pauv synchronously nrog npib tsib xee thiab chromium yav tom ntej, qhov chaw txaus txaus rau feem ntau nruab nrab - qauv kev lag luam thiab cov kav dej hauv nroog.

316L molybdenum-muaj tsawg- carbon yeeb nkab fittings: tus nqi siab tshaj ntawm cov pa roj carbon monoxide, 15%–25% siab dua 304. Ntxiv molybdenum alloy thiab ultra- carbon smelting tsawg nce nqi tsim khoom, tsim rau siab -corrosion siab{8} cov kav dej thiab cov kav dej huv.

2. Corrosion Resistance

Kev tiv thaiv -kev ua haujlwm corrosion: 201 < 430 < 304 < 316L

201: Tsis muaj zog xeb- pov thawj muaj peev xwm, tsuas yog ruaj khov hauv cov kav dej hauv tsev qhuav qhuav. Ncua rau pitting xeb thiab daj stains nyob rau hauv av ntub, ntug hiav txwv dej los yog acidic me ntsis ib puag ncig, txwv tsis pub rau sab nraum zoov thiab corrosive kua xa.

430: Zoo tiv thaiv - oxidation kev ua tau zoo nyob rau hauv cov huab cua qhuav, tab sis tsis zoo chloride thiab ntsev tsuag kuj. Nws yuav corrode sai heev nyob rau hauv ntev -lub sij hawm chav thiab ntug hiav txwv ntsev pos huab, tsuas yog siv tau rau qhuav cov kav dej txias hauv tsev.

304: Balanced comprehensive tiv thaiv -corrosion peev xwm. Tiv thaiv atmospheric xeb, dej tshiab thiab tsis muaj zog nruab nrab erosion, dhau tus qauv 48-96 teev ntsev tshuaj tsuag, dav siv rau hauv nroog sab nraum zoov dej, rhiav zaub mov thiab cov kav dej dav dav. Nws tsis tuaj yeem sawv ntev -lub sij hawm dej hiav txwv thiab muaj zog acid- hauv paus xov xwm.

316L: Sab saum toj -tier corrosion kuj. Molybdenum caij zoo txhim kho kev tiv thaiv rau chloride ion, dej hiav txwv, kua qaub thiab alkali, zoo tiv thaiv pitting thiab crevice corrosion. Nws tuaj yeem khiav ruaj khov hauv cov dej hauv hiav txwv, cov dej khib nyiab thiab cov ntug dej hiav txwv siab -cov kav dej ntsev ib puag ncig qhov twg lwm qib ua tsis tiav.

3. Daim ntawv thov kev lag luam

201 Stainless Hlau Yeeb Fittings

Txwv rau qis- nqi qis hauv tsev tsis yog- cov kav dej ntub dej, cov kav dej me me hauv tsev thiab cov kav dej hauv tsev ib ntus. Tsis pub rau chav ua noj, zaub mov, dej hiav txwv thiab sab nraum zoov mus tas li pipeline engineering.

430 Stainless Hlau Yeeb Fittings

Feem ntau yog siv rau cov kav dej txias hauv tsev hauv tsev, cov khoom siv hauv tsev me me nrog cov kua dej sib txuas, cov kav dej cua sov hauv tsev qhuav thiab qis - siab tsis yog - corrosive civil piping systems.

304 Stainless Hlau Yeeb Fittings

Cov qib thoob ntiaj teb feem ntau suav nrog ntau yam kev lag luam: cov kav dej hauv nroog, cov kav dej xa khoom noj khoom haus & dej haus ua cov kav dej, cov kav dej siv tshuaj ntau lawm, lub tsev hluav taws kub - cov kav dej sib ntaus sib tua, cov khoom siv tiv thaiv ib puag ncig, cov khoom siv petrochemical tsawg- cov kav dej nruab nrab thiab cov khoom siv tu vaj tse.

316L Stainless Hlau Yeeb Fittings

Tshwj xeeb rau siab -txheej txheem corrosive thiab huv si: marine offshore platform piping, seawater desalination pipeline accessories, tshuaj acid-puag tshuaj xa fittings, kho mob sterile kua pipelines, coastal municipal water supply systems thiab high-kawg tshuaj sterile ntau lawm kab.

4. Kev Pabcuam Lub Neej

Kev pab cuam lub neej txawv heev nyob rau hauv qhov chaw ua hauj lwm sib txawv, ua tiav cov yeeb nkab fittings raws li tus qauv:

Qhuav hauv tsev kaw ib puag ncig: 201 kav 6-8 xyoo; 430 kav 10-15 xyoo; 304 tuaj yeem ua haujlwm tshaj 30 xyoo; 316L ua tiav cov haujlwm ruaj khov ruaj khov yam tsis muaj corrosion tsis ua haujlwm.

Ordinary nroog sab nraum zoov cov kav dej tshiab: 201 xeb thiab ua tsis tiav hauv 2-3 xyoos; 430 tsuas yog ua haujlwm 5-7 xyoo; 304 tswj kev ua haujlwm ruaj khov rau 18-25 xyoo.

Dej hiav txwv ntsev pos huab & tshuaj tsis muaj zog corrosive pipeline: Tsuas yog 316L tuaj yeem khiav nyab xeeb rau 28-35 xyoo; 201, 430 thiab 304 yuav ua rau muaj kev cuam tshuam loj heev hauv 5-10 xyoo, ua rau cov kav dej xau.

5. Kev ua tau zoo

201: High hardness thiab hnyav ua hauj lwm hardening, tsawg ductility. Tsuas yog haum yooj yim txiav thiab ntxhib xov tig; yooj yim tawg thaum lub sij hawm khoov, zoo polishing thiab tag nrho vuam, siab tus nqi rau complex tsim fittings.

430: Smooth tig thiab txiav kev ua haujlwm rau huab hwm coj- tsim cov threaded yooj yim fittings. Kev sib sib zog nqus tsis zoo thiab khoov tawv, yooj yim rau tawg thaum ua tshwj xeeb - zoo li lub luj tshib thiab tees nrog loj deformation.

304: Zoo heev machinability thiab weldability, ruaj khov ductility thiab qis ua hauj lwm hardening ceev. Haum rau txhua qhov kev ua haujlwm xws li precision threading, txias dabtsi yog khoov, laser txiav, argon arc vuam thiab sab hauv daim iav polishing, siab tiav cov khoom tawm los rau txhua tus qauv thiab customized yeeb nkab fittings.

316L: khaws cov kev ua tau zoo ntawm cov hlau austenitic; ultra-tsim carbon tsawg tshem tawm cov vuam intergranular corrosion. Zoo meej rau siab -precision sanitary polished yeeb nkab fittings thiab complex anti-corrosion customized connectors nrog nruj vuam yuav tsum.
