Khoom Taw qhia

Stainless hlau 316 kavsawv cev rau tus qauv ntsuas rau nruab nrab - mus rau - qib siab corrosion kuj nyob rau hauv cov txheej txheem nruj heev. Lub hauv paus sib txawv ntawm Qib 316 thiab ntau qib austenitic (xws li 304) nyob hauv nws cov tshuaj muaj pes tsawg leeg. Qib 316 yog txhim khu kev qha nrogmolybdenum(feem ntau yog 2.0% mus rau 3.0%), uas hloov pauv nws cov qauv siv lead ua lattice nyob rau hauv cov tshuaj tiv thaiv. HT PIPE is aSS316 cevtus xa khoom nrog 15+ kev xa tawm.Tiv tauj pebkom paub ntau ntxiv thiab quotes dawb!

Sib ntaus sib tua chloride-Induced Pitting

Nyob rau hauv ib cheeb tsam ntawm ntug dej hiav txwv los yog tshuaj ua cov nroj tsuag, chloride ions nquag tawm tsam cov passive chromium oxide txheej ntawm cov qauv hlau. Qhov kev puas tsuaj hauv cheeb tsam no ua rau pitting hnyav thiab crevice corrosion.

Qhov sib ntxiv ntawm molybdenum ua raws li tus neeg sawv cev ncaj qha -tus neeg sawv cev, stabilizing cov zaj duab xis passive thiab txo tus nqi ntawm qhov chaw propagation. Tus cwj pwm no tau txais qib 316 nws lub koob npe nrov ua tus thawj coj"marine qib"stainless hlau.

Lub 316 vs . 316L Distinction

Thaum sau cov nqi ntawm cov ntaub ntawv (BOM), xaiv ntawm tus qauv 316 thiab nws cov qib qis -carbon counterpart,316L, yog ib kauj ruam tsim qauv tseem ceeb:

Sensitization Risk:Thaum lub sij hawm vuam phab ntsa hnyav, qhov kub ntawm 450℃thiab 850℃ua rau cov pa roj carbon khi nrog chromium raws li cov ciam teb, tsim chromium carbides. Cov txheej txheem no, hu ua rhiab heev, tawm hauv cov cheeb tsam uas nyob ib sab uas muaj kev cuam tshuam rau intergranular corrosion.

Qhov qis-Carbon Solution:Los ntawm capping carbon cov ntsiab lus ntawm 0.035%, 316L zoo tshem tawm cov nag lossis daus carbide thaum vuam. Yog li ntawd, rau cov tshuab uas yuav tsum tau siv dav hauv kev vuam yam tsis muaj kev tshaj tawm -weld heat treatment (PWHT), 316L yog tus qauv zoo tshaj plaws engineering.

Primary Manufacturing Standards & Specifications

Cov kav dej muaj cov kav dej yuav tsum ua raws li cov qauv thoob ntiaj teb nruj kom ntseeg tau tias muaj kev ruaj ntseg thiab qhov sib npaug ntawm qhov sib npaug. Kev muab cov qauv tsim nyog yog nyob ntawm koj daim ntawv thov kev tsom xam: kev sib kis ntawm cov kua dej, cov khoom siv tshuab, lossis hloov hluav taws xob.

ASTM A312: Cov txheej txheem Piping Standard

Rau cov kev pabcuam corrosive thiab siab - ib puag ncig kub,ASTM A 312 Cov Lus Qhia(los yog ASME SA312) yog thawj qhov kev qhia tshwj xeeb. Nws tswj seamless, ncaj-seam welded, thiab hnyav hnyav- ua haujlwm austenitic kav.

Seamless (SMLS):Ua los ntawm kev tho qhov kub thiab txias kos duab. Nws nta tsis ntev weld seam, ua rau nws xaiv qhov kev xaiv rau siab -siab, tseem ceeb- kab kev nyab xeeb.

Welded (WLD / ERW / EFW):Tsim los ntawm cov khoom lag luam tiaj tus thiab koom nrog cov txheej txheem vuam tshuab tsis siv neeg hlau (lossis ntawm hluav taws xob fusion vuam rau cov kab loj dua). Welded xaiv muab cov phab ntsa thickness concentricity zoo heev thiab yog tus nqi siab heev -zoo rau cov yeeb nkab nominal loj.

Tus khub Tubing Standards

Nws yog ib qho tseem ceeb kom tsis txhob cuam tshuam cov qauv yeeb nkab nominal nrog cov tshuab tshwj xeeb lossis cov qauv siv hluav taws xob:

ASTM A213 Cov Lus Qhia:Npog seamless ferritic thiab austenitic alloy steel boilers, superheaters, thiab tshav kub -exchanger tubes qhov twg tshav kub zoo-coefficients pauv thiab nruj phab ntsa{2}} kam rau ua yog yuav tsum tau.

ASTM A269 Txuj:Tswj seamless thiab welded austenitic steel tubing npaj rau kev dav dav, tsis yog - siab- cov kev pabcuam kho tshuab, cov cuab yeej siv, lossis cov dej thauj yooj yim uas tsis tas yuav tsum muaj lub sijhawm teev cov yeeb nkab loj.
