Pipeline cov ntaub ntawv thiab cov yam ntxwv:
1. steel yeeb nkab:
Hom: seamless yeeb nkab (siab siab lub ntsiab kab), ncaj seam / kauv welded yeeb nkab (nruab nrab thiab tsis tshua muaj siab).
Cov khoom siv: L245 (GB/T 9711), X42-X80 siab- lub zog steel (ntev- nrug), kev kho tiv thaiv corrosion (3PE, FBE txheej) yog yuav tsum tau.
Cov xwm txheej ntawm daim ntawv thov: siab-siab ntev- cov kav xa mus los nyob deb, kev sib txuas hauv nroog hauv qab, thiab ntu kev hla.
2. Polyethylene yeeb nkab (PE yeeb nkab):
Qib: PE80 (qhov nruab nrab siab), PE100 / PE100-RC (siab siab / ua haujlwm kom qeeb kev loj hlob).
Standard: GB 15558.1 (pipe), GB 15558.2 (pipe fittings), tus nqi SDR txiav txim siab lub peev xwm bearing (xws li SDR11, lub siab tsis kam yog siab dua).
Qhov zoo: Corrosion kuj, zoo yoog raws, muaj zog vuam thiab sealing, haum rau faus nruab nrab thiab qis cov yeeb nkab sib txuas.
Cov ntaub ntawv tshwj xeeb:
Cov yeeb nkab hlau (nruab nrab thiab tsis tshua muaj siab faus), tooj liab yeeb nkab / stainless hlau yeeb nkab (sab hauv sab hauv qab yeeb nkab), cov yeeb nkab sib xyaw (xws li txhuas- cov yeeb nkab yas, cov yeeb nkab sab hauv tsev).
