Welded Steel Pipe Pressure Rating Table
Aug 31, 2023
Khoom Description
Lub siab ntsuas ntawm welded steel yeeb nkab yog nyob ntawm ntau yam, nrog rau cov khoom siv yeeb nkab, phab ntsa thickness, txoj kab uas hla, qhov kub thiab txias, thiab hom dej xa tawm. Kev ntsuas siab feem ntau yog txiav txim siab los ntawm cov qauv kev lag luam thiab cov lej, xws li ASME B31.3 rau cov txheej txheem piping lossis ASME B31.1 rau cov kav dej.

Yuav Ua Li Cas Nyeem Daim Ntawv Ntsuas Siab
Txhawm rau kom nkag siab tag nrho cov lus ntsuas siab, koj yuav tsum paub yuav ua li cas nyeem cov kab ntawv. Cov kab no feem ntau qhia cov ntaub ntawv hauv qab no:
1. Pipe Size: Qhov no yog hais txog txoj kab uas hla ntawm cov yeeb nkab, feem ntau ntsuas hauv inches los yog millimeters.
2. Phab ntsa thickness: qhia lub thickness ntawm cov yeeb nkab. Nws yog ib qho tsim nyog sau cia tias qhov tuab ntawm cov yeeb nkab muaj qhov cuam tshuam rau qhov ntsuas siab. Qhov tuab ntawm cov yeeb nkab, qhov siab dua qhov ntsuas.
3. Khoom Qib: Qhov no yog hom khoom siv los ua cov yeeb nkab. Cov khoom siv feem ntau yog carbon hlau, stainless hlau, hlau alloy, thiab lwm yam.
4. Kev khiav hauj lwm kub: Qhov siab tshaj plaws kev khiav hauj lwm kub ntawm daim ntawv thov.
5. Kev ntsuas siab: Qhov no yog qhov siab tshaj plaws uas lub raj xa dej tuaj yeem tiv taus. Feem ntau ntsuas hauv psi (pounds ib square inch).
