API 5L x70 psl2 umbhobho intsimbi engenamthungo

Umbhobho we-API 5L X70 yimathiriyeli ye-premium grade piping in API 5L imilinganiselo esemgangathweni. Ikwabizwa ngokuba ngumbhobho we-L485, njengoko ubuncinci bamandla esivuno kwi-485 Mpa (70,300 psi). I-API 5L X70 ibandakanya iintlobo zokuvelisa kwiintlobo ezingenamthungo kunye ne-welded (RW, SAW), zombini ezisetyenziselwa ukuhanjiswa kweoli kunye negesi.

Iziphelo ze-API 5L X70 PSL2 Umbhobho

Iziphelo zetyhubhu zigudile, azinamisonto.
Ukusuka kwi-60.3 ubukhulu be-beveled ngokwemigangatho:
I-DIN, EN - a = 40 ° - 60 °, c = ukuya kwi-2 mm
ASME – a = 75° ± 5°, c = 1,6 ± 0,8 mm

Ukumakishwa kwe-API 5L X70 PSL2 Umbhobho kunye ne-tube bundles

Iityhubhu ezinodayamitha ukuya kwi-1 ½” ziphawulwe ngophawu kwinyanda. Iityhubhu ezinobukhulu obungaphezu kwe-1½” ziphunyezwa ngokwemiyalelo okanye ngokwesicelo.

I-API 5L X70 PSL2 Umbhobho - ukhuseleko lomphezulu

Imibhobho yomgca inikezelwa ngaphandle kokhuseleko lwexeshana ekudlekeni. Ngesicelo kunokwenzeka ukuhambisa iityhubhu kunye nokhuseleko oluvunyelweneyo lwe-anticorrosion. Iziphelo zetyhubhu zinokuvalwa ngeplagi yeplastiki.
