I-API 5L x70 psl2 ipayipi lensimbi engenamthungo

Ipayipi le-API 5L X70 liwumsebenzi wamapayipi webanga le-premium ekucacisweni okujwayelekile kwe-API 5L. Iphinde ibizwe ngepayipi i-L485, njengoba ikhiqiza amandla amancane ku-485 Mpa (70,300 psi). I-API 5L X70 ihlanganisa izinhlobo zokukhiqiza ngezinhlobo ezingenamthungo nezishiselwe (i-RW, SAW), zombili ezifakelwa uwoyela negesi.

Iziphetho ze-API 5L X70 PSL2 Pipe

Iziphetho zamashubhu zibushelelezi, azinayo imicu.
Kusuka ku-60.3 ububanzi be-beveled ngokuvumelana nezindinganiso:
I-DIN, EN – a = 40° – 60°, c = kuya ku-2 mm
ASME – a = 75° ± 5°, c = 1,6 ± 0,8 mm

Ukumakwa kwe-API 5L X70 PSL2 Ipayipi nezinqwaba zamashubhu

Amashubhu anobubanzi obufika ku-1 ½” amakwe ilebula kunqwaba. Amashubhu anobubanzi obukhulu kuno-1 ½” asetshenziswa ngokweziqondiso noma ngokucelwa.

I-API 5L X70 PSL2 Pipe – ukuvikelwa kwendawo

Amapayipi olayini ahlinzekwa ngaphandle kokuvikelwa kwesikhashana ekugqwaleni. Uma uceliwe kungenzeka ukuletha amashubhu anezivikelo ze-anticorrosion okuvunyelwene ngazo. Iziphetho zeshubhu zingavalwa ngepulaki lepulasitiki.
