Teem caij 20 thiab Teem sijhawm 40 yog ob qhov kev ntsuas siab hauv cov yeeb nkab steel. Qhov sib txawv tseem ceeb nyob rau hauv phab ntsa tuab, lub siab muaj peev xwm, thiab cov xwm txheej siv tau: Teem sijhawm 40 muaj cov phab ntsa tuab dua thiab muaj zog dua, thiab tsim nyog rau siab - cov kav dej muaj zog; Teem caij 20 muaj cov phab ntsa nyias nyias thiab tsim nyog rau qis - siab lossis tsis yog - cov dej tseem ceeb.

S20 thiab S40 pipeline Application Comparison
| Scenario | Pom zoo teem caij | Yog vim li cas |
| Siab -Nias Chav / Roj & Roj | S40 | Yuav tsum muaj cov phab ntsa tuab kom ntseeg tau tias muaj kev nyab xeeb nyob rau hauv siab. |
| Loj Txoj kab uas hla | S20 | Tsis tshua muaj siab; S20 txo cov txheej txheem thauj khoom thiab nqi. |
| Municipal Dej / Hluav Taws Kub | S40 | Kev lag luam tus qauv; tso cai rau corrosion margin thiab cuam tshuam tsis kam. |
| Tsawg-Npaum Dej / Temp Kab | S20 | Ua ntej kev lag luam; Cov dej cuam tshuam rau ntawm phab ntsa yog tsawg heev. |
| Plant Utilities (Air / Dej) | S40 | Feem ntau cov nroj tsuag spec; fittings (lub luj tshib, tees) yog qhov yooj yim tshaj plaws rau qhov chaw. |
