Yog tias koj tab tom yuav 316 stainless hlau kav, ib qho tseem ceeb tshaj plaws kom nkag siab yog cov yeeb nkab tuab, feem ntau hu ua yeeb nkab teem caij (SCH). Xaiv qhov raug thickness ncaj qha cuam tshuam rau lub siab ua haujlwm, durability, thiab qhov project nqi.
Hauv phau ntawv qhia no, peb piav qhia cov txheej txheem thickness ranges, specifications, thiab yuav ua li cas xaiv txoj kev xaiv rau koj daim ntawv thov.
Dab tsi yog SS 316 stainless hlau tubing?
SS 316 yog austenitic stainless hlau uas muaj molybdenum (2.0% - 2.5%). Piv rau SS 304, nws muaj kev tiv thaiv zoo tshaj rau cov tshuaj chloride, kua qaub, thiab dej hiav txwv corrosion, ua rau nws haum rau cov tshuaj thiab petrochemical pipelines, tshav kub exchangers thiab siab piping, marine thiab offshore lug, thiab zaub mov thiab kws ua kab.
Dab tsi yog Thickness ntawm 316 Stainless Hlau Yeeb Nkab?
Phab ntsa tuab ntawm 316/316L stainless hlau kav nws txawv heev nyob ntawm daim ntawv thov tshwj xeeb; rau cov kev qhia tshwj xeeb, phab ntsa tuab feem ntau yog li ntawm 0.6 hli mus rau 12.7 hli (kwv yees li 0.024 "mus rau 0.5"), txawm hais tias hnyav - cov kav dej muaj peev xwm ua rau phab ntsa tuab tshaj 50 hli. Cov yeeb nkab phab ntsa tuab feem ntau txhais los ntawm "Schedule" tooj (xws li Sch 5S, 10S, 40S, 80S), nrog rau cov Nominal Pipe Size (NPS) specifications spanning a range from 1/8" to 36".
SCH 5 / SCH 10 → Nyias phab ntsa (lub teeb yuag, tsis tshua muaj siab)
SCH 40 → Txheem thickness (kev siv dav dav)
SCH 80 → Thick wall (kev siv siab)
SCH 160 / XXS → Ntxiv tuab (hnyav heev)
Qhov tseeb phab ntsa thickness txawv nyob ntawm cov yeeb nkab txoj kab uas hla (NPS).
Qhov txawv ntawm ASME B36.19 thiab ASME B36.10 yog dab tsi?
Hauv kev lag luam stainless hlau, tuab yog tswj hwm los ntawm Schedule (Sch) system, feem ntau txhais los ntawm ASME B36.19 (rau stainless) thiab ASME B36.10 (rau carbon steel).
Rau ib qho twg muab Nominal Pipe Size (NPS), Sab Nraud Diameter (OD) tseem nyob tas li, tsis hais qhov tuab. Raws li tus lej Teem caij nce (xws li, los ntawm Sch 10S mus rau Sch 80S), phab ntsa thickness yuav loj dua, thiab Internal Diameter (ID) txo.

Qhov txawv ntawm 316 SCH 40 yeeb nkab thiab SCH 80 yog dab tsi?
Thawj qhov sib txawv ntawm Schedule 40 (SCH 40) thiab Schedule 80 (SCH 80) cov kav dej ua los ntawm 316 cov khoom nyob rau hauv qhov tseeb tias SCH 80 nta cov phab ntsa tuab dua thiab cov kab me me, thiab muaj qhov ntsuas siab dua SCH 40. SCH 40 feem ntau suav hais tias yog cov qauv kev qhia tshwj xeeb 8} raws li kev siv qis dua 80- txawv los ntawm nws qhov kev txhim kho lub zog thiab kev ua haujlwm ntev-yog tsim tshwj xeeb rau kev lag luam ib puag ncig uas muaj kev kub siab, hnyav hnyav, lossis cov kab mob corrosive heev.
Dab tsi yog "12.5% Wall Tolerance" hauv ASTM A312?
According to the ASTM A312 standard for seamless stainless steel pipe, the wall thickness is allowed a negative tolerance of 12.5%. For example, if the nominal thickness is 10mm, a pipe arriving at 8.75mm is technically compliant. If your safety code requires a strict minimum, you must specify "Minimum Wall" instead of "Nominal Wall."
