Qhov sib txawv loj ntawm lub sijhawm 40 thiab lub sijhawm 80 yeeb nkab yog cov phab ntsa tuab, sab hauv txoj kab uas hla, thiab lawv qhov hnyav. Teem sijhawm 80 yuav muaj phab ntsa tuab dua, me me hauv txoj kab uas hla thiab qhov hnyav dua li Teem caij 40 yeeb nkab ntawm qhov muab cov yeeb nkab nominal loj.
A 1″ NPScev 40muaj ib lub phab ntsa nyias thiab ib txoj kab uas hla loj dua li 1 "NPScev 80, thiab nws yog siv rau kev siv qis thiab kub. Lub ntsiab sib txawv ntawm SCH 40 thiab SCH 80 yog phab ntsa tuab, cuam tshuam rau lub siab - nqa lub peev xwm. SCH 80 cov kav dej, nrog lawv cov phab ntsa tuab, tuaj yeem tiv taus siab dua piv rau SCH 40 cov kav dej. Qhov no ua rau SCH 80 cov kav dej tsim nyog rau cov ntawv thov uas qhov siab siab siab yog qhov xav tau.
Qhov txawv tseem ceeb: SCH 40 vs SCH 80 Steel Pipe
Phab ntsa Thickness:Rau cov Nominal Pipe Size (NPS), SCH 80 yeeb nkab nta phab ntsa tuab dua SCH 40.
Internal Diameter (ID):Vim tias Sab Nraud Sab Nraud (OD) tseem nyob ruaj khov rau NPS cov qauv, cov phab ntsa ntxiv ntawm SCH 80 txo nws qhov chaw ntws sab hauv.
Kev ntsuas siab:Lub phab ntsa tuab ntawm SCH 80 muab lub zog tensile ntau dua thiab lub hoop tsis kam, tso cai rau nws tiv taus kev ua haujlwm siab dua.
Nyhav & Nqi:SCH 80 yeeb nkab muaj cov khoom siv raw, ua rau nws hnyav dua thiab tus nqi siab dua SCH 40.

Yuav Ua Li Cas Xaiv Ntawm SCH 40 thiab SCH 80
Xaiv Teem sijhawm 40 thaum:
Kev khiav hauj lwm siab nyob twj ywm nyob rau hauv cov qauv siv hluav taws xob lossis qis - cov kev txwv kev ua haujlwm siab.
Qhov siab tshaj plaws yuav tsum tau (qhov loj dua hauv txoj kab uas hla yuav txo tau kev sib txhuam taub hau).
Kev txo qhov hnyav thiab tus nqi ua haujlwm yog lub hom phiaj tseem ceeb ntawm txoj haujlwm.
Xaiv Teem sijhawm 80 thaum:
Lub kaw lus siab tshaj SCH 40 txwv, los yog xav tias yuav tsum muaj lub siab spikes / dej rauj.
Cov kav dej tau muab tso rau hauv qhov siab -kev nyuaj siab, muaj kev phom sij, lossis ib puag ncig corrosive heev.
Mechanical threading yuav tsum tau (threading tshem tawm cov khoom siv phab ntsa, txo cov phab ntsa zoo).
