Txawm hais tias koj yog tus tshiab rau lub raj xa dej lossis cov yeeb nkab alloy los yog tau ua haujlwm rau ntau xyoo, lo lus "Schedule 40" tsis yog tshiab rau koj.Nws tsis yog ib lo lus yooj yooj yim xwb, nws yog ib qho kev ntsuas tseem ceeb, yog li cia peb khawb me ntsis thiab nrhiav seb vim li cas Teem caij 40 thiaj li nrov!
Teem caij 40 yog dab tsi
Lub Sijhawm 40 yeeb nkab yog cov yeeb nkab uas muaj cov phab ntsa tshwj xeeb.Qhov tshwj xeeb phab ntsa thickness yuav txawv nyob ntawm seb lub cheeb sab nraud ntawm cov yeeb nkab.Qhov no yog vim tus lej tom qab Teem sijhawm tsis ncaj qha mus rau cov phab ntsa tshwj xeeb, tab sis yog qhov categorization.
Cov mis rau kev suav cov Sijhawm Sijhawm yog ib txoj hauv kev yooj yim los kwv yees qhov kev sib raug zoo ntawm phab ntsa tuab ntawm cov yeeb nkab thiab lub siab uas nws raug.
Cov mis yog raws li nram no:
Teem caij = 1000 (P / S)
Psawv cev rau kev tsim ua haujlwm siab ntawm cov yeeb nkab, feem ntau hauv psi (pounds ib square inch)
Ssawv cev rau qhov tsawg kawg nkaus kev ntxhov siab ntawm cov khoom siv yeeb nkab ntawm kev ua haujlwm kub, kuj yog psi (pounds ib square inch).
Cov qauv no muab cov txheej txheem theoretical rau kev nkag siab txog kev sib raug zoo ntawm cov kav dej tuab nrog cov txheej txheem sib txawv thiab qhov siab tshaj plaws uas lawv tuaj yeem tiv taus.Nyob rau hauv kev xyaum, Schedule tus nqi ntawm ib tug yeeb nkab yog predefined nyob rau hauv tus qauv.

Ua raws li Cov Qauv
Teem sijhawm 40 piping ua raws li cov qauv kev lees paub thoob ntiaj teb xws li American Society for Testing and Materials (ASTM) thiab American Society of Mechanical Engineers (ASME) kom ntseeg tau tias nws zoo thiab ua haujlwm tau zoo.
Yooj yim ntawm kev yuav khoom
Vim nws txoj kev siv dav dav, Teem sijhawm 40 piping yog muaj nyob hauv khw thiab tau yooj yim yuav hauv ntau qhov ntau thiab tsawg thiab cov khoom siv.
Kev txheeb xyuas qhov tob ntawm Schedule 40 kav dej qhia tau hais tias lawv muaj qhov zoo tshaj plaws tshuav nyiaj li cas ntawm tus nqi, lub zog, durability, thiab daim ntawv thov yooj.Qhov no tsis tsuas yog ua rau nws yog ib feem tseem ceeb ntawm ntau qhov project.Raws li kev siv thev naus laus zis thiab cov qauv tau hloov kho tas li, Teem sijhawm 40 cov kav dej yuav tsis xav tau txuas ntxiv mus siv thoob plaws ntiaj teb los txhawb kev tsim kho vaj tse thiab kev tsim kho kev lag luam.
